+/** This file implements two fixed point number classes. These numbers can have a fractional
+part but are actually standard integers under the hood which makes calculations with them
+efficient on platforms which do not have a FPU like most micro-controllers. These numbers can be
+signed (SFixMath2) or unsigned (UFixMath2).
+
+A fixed point number has its range defined by the number of bits encoding the integer part (NI 
+in the following) and its precision by the number of bits encoding the fractional part (NF).
+
+Like standard C(++) types, the fixed point numbers defined here are following some rules:
+ - any fixed type can be converted to another *as long as the value can be represented in the destination type*. Casting to a bigger type in term of NI and NF is safe, but reducing NI can lead to an overflow if the new type cannot hold the integer value and reducing NF leads to a loss of precision.
+ - all operations between fixed point number is safe (it won't overflow) and preserve the precision. In particular:
+   - only addition, subtraction and multiplication are implemented
+   - any operation between a signed and an unsigned leads to a signed number
+   - resulting numbers will be casted to a type big enough to store the expected values. It follows that it is worth starting with types that are as small as possible to hold the initial value.
+ - all operations between a fixed point number and a native type (int, float, uint) are *not* safe. If the resulting value cannot be represented in the fixed point type it will overflow. Only addition, subtraction, multiplication and right/left shift are implemented.
+ - safe right/left shifts, which return the correct value in the correct type are implemented as .sR<shift>() and .sL<shift>() respectively, shift being the shifting amount.

 /** This file implements two fixed point number classes. These numbers can have a fractional

-
-A fixed point number has its range defined by the number of bits encoding the integer part (NI 
-in the following) and its precision by the number of bits encoding the fractional part (NF).
-
-Like standard C(++) types, the fixed point numbers defined here are following some rules:
- - any fixed type can be converted to another *as long as the value can be represented in the destination type*. Casting to a bigger type in term of NI and NF is safe, but reducing NI can lead to an overflow if the new type cannot hold the integer value and reducing NF leads to a loss of precision.
- - all operations between fixed point number is safe (it won't overflow) and preserve the precision. In particular:
-   - only addition, subtraction and multiplication are implemented
-   - any operation between a signed and an unsigned leads to a signed number
-   - resulting numbers will be casted to a type big enough to store the expected values. It follows that it is worth starting with types that are as small as possible to hold the initial value.
- - all operations between a fixed point number and a native type (int, float, uint) are *not* safe. If the resulting value cannot be represented in the fixed point type it will overflow. Only addition, subtraction, multiplication and right/left shift are implemented.
- - safe right/left shifts, which return the correct value in the correct type are implemented as .sR<shift>() and .sL<shift>() respectively, shift being the shifting amount.

+    - all operations between fixed point number is safe (it won't overflow) and preserve the precision. In particular:
+    - only addition, subtraction and multiplication are implemented
+    - any operation between a signed and an unsigned leads to a signed number
+    - resulting numbers will be casted to a type big enough to store the expected values. It follows that it is worth starting with types that are as small as possible to hold the initial value.
+    - all operations between a fixed point number and a native type (int, float, uint) are *not* safe. If the resulting value cannot be represented in the fixed point type it will overflow. Only addition, subtraction, multiplication and right/left shift are implemented.
+    - safe right/left shifts, which return the correct value in the correct type are implemented as .sR<shift>() and .sL<shift>() respectively, shift being the shifting amount.

Subject: [PATCH 037/215] Add a multi-complation-unit example

This is pretty pointless at the time being, but will be marginally useful, to demonstrate how to customize config
in that case, once Mozzi itself is compiled as single compilation unit.

Add it now, already (at the Mozzi2-branch), so it is available as a baseline for the "report" action in future PRs.

Subject: [PATCH 038/215] Start config rework

This does not actually do anything yet, but I hope the outline is becoming visible.

Plan is to finish this outline for AVR, first, then adapt MozziGuts, and get it to compile for AVR, then follow up on the other platforms.

+ *
+ * TODO: link to specific documentation for each option/platform, and/or spell out, what is supported, where
+ *
+ * Supported values:
+ *   - MOZZI_OUTPUT_PWM Output using pulse width modulation (PWM) on a GPIO pin. This is the default on most platforms.
+ *                      On the Arduino Uno (more generally ATMEGA328P), this allows for a sample resolution of 488 (almost 9 bits) on pin 9.
+ *                      Usable pins and resolution will be different on other boards.
+ *   - MOZZI_OUTPUT_2PIN_PWM Output using pulse width modulation on two GPIO pins, where one pin represents the lower bits, and the other the higer bits of the sample.
+ *                      On the Aduino Uno, this allows for 14 bits of resolution on pins 9 (low) and 10 (high). For further information (wiring etc.) see TODO add ref.
+ *   - MOZZI_OUTPUT_EXTERNAL Output is not controlled by Mozzi itself, but left to the user sketch. This setting allows to completely customize the audio output, e.g.
+ *                      for connecting to external DACs. For more detail, @see AudioOuput
+ *   - MOZZI_OUTPUT_PDM_VIA_I2S Output pulse density modulated (PDM) samples via a (hardware) I2S interface (without a DAC connected to it).
+ *   - MOZZI_OUTPUT_PDM_VIA_SERIAL Output pulse density modulated (PDM) samples via a hardware serial interface.
+ *   - MOZZI_OUTPUT_I2S_DAC Output samples to a PT8211 (or compatible) DAC connected to a hardware I2S interface.

+/** @ingroup hardware
+ * @page hardware_avr Mozzi on classic Arduino, Teensy (2.x and 3.x), Arduino Mega, and other 8 bit "AVR"/ATMEGA architecture boards
+ *
+ * The following audio modes (@see MOZZI_AUDIO_MODE) are currently supported on this hardware. In all cases, Timer 1 is claimed, and
+ * is not available for any other purpose:
+ *   - MOZZI_OUTPUT_PWM
+ *   - MOZZI_OUTPUT_2PIN_PWM
+ *   - MOZZI_OUTPUT_EXTERNAL
+ *
+ * In all cases, Timer 1 is claimed, and is not available for any other purpose.
+ *
+ * @section MOZZI_OUTPUT_PWM
+ * For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured
+ * within this tight limit. In particular, the default setup on the
+ * Arduino UNO is:
+ *    - Mono: Pin 9 -> configurable using MOZZI_AUDIO_PIN_1
+ *    - Stereo: Pin 9 (left) and Pin 10 (right)  -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2
+ * For pinouts on other boards, refer to config/known_16bit_timers.
+ *
+ * Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.
+ *
+ * The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution
+ * currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.
+ *
+ * @section MOZZI_OUTPUT_2PIN_PWM
+ * For MOZZI_OUTPUT_2PIN_PWM, Timer 2 is used in addition to Timer 1. Output is split across two pins (again, both connected to Timer 1), with each
+ * outputting 7 bits for a total of 14. Add signals through a 3.9k resistor on the "high" pin and 499k resistor on "low" pin.
+ * Use 0.5% resistors or select the most accurate from a batch. As discussed on http://www.openmusiclabs.com/learning/digital/pwm-dac/dual-pwm-circuits/
+ * Also, there are higher quality output circuits are on the site.
+ *
+ * The default pinout in this mode is: 
+ *    - Pin 9 (high bits) and Pin 10 (low bits) -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW
+ * For pinouts on other boards, refer to config/known_16bit_timers.
+ *
+ * Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE, and is much higher (125kHz), by default: MOZZI_PWM_RATE.
+ * 
+ * The default sample resolution is 7 bits per pin, for a total of 14 bits. This can be configured within hardware limits (@see MOZZI_PWM_RATE) using
+ * MOZZI_AUDIO_BITS_PER_CHANNEL, but beware that increasing this will require even more accuracy in our output resistors (see the linked documentation, above).
+ *
+ * @section MOZZI_OUTPUT_PWM

+ * This improves the signal quality at less cost than doubling the audio rate itself. However, increasing this too far will limit the dynamic resolution of the samples that can be

+ * In the more simple case (MOZZI_OUPUT_EXTERNAL_TIMED), Mozzi will still take care of buffering the samples, and calling this function

+ * your platform.
+ *
+ * Should you desire even more control - perhaps because your board, or your external DAC already comes with a rate controlled DMA buffer -
+ * using MOZZI_OUPUT_EXTERNAL_CUSTOM also bypasses Mozzis sample buffer. In addition to audioOutput(), you will then need to provide
+ * a definition for canBufferAudioOutput(), which will control the rate at which samples are produced. In essence, whenever
+ * canBufferAudioOutput() returns true, Mozzi will call updateAudio(), and pass the produced sample to audioOutput(), unbuffered. It is
+ * entirely your job to make sure that this actually happens at MOZZI_AUDIO_RATE, and / or an appropriate buffer gets used.

-Holds the audio rate setting.
-AUDIO_RATE can be \#defined as 16384 or 32768 Hertz in Mozzi/mozzi_config.h.
-
-Mozzi's original audio mode, now called STANDARD, uses 16384 Hz, chosen as a
-compromise between the sample rate (interrupt rate) and sample bitdepth (pwm
-width), which are interdependent due to the way pulse wave modulation is used to
-generate the sound output.
-An AUDIO_RATE of 32768 Hz works in STANDARD_PLUS and HIFI modes.
-Of course, doubling the sample rate halves the amount of time available to calculate the each sample, so it
-may only be useful for relatively simple sketches.  The increased frequency response can also make
-unwanted artefacts of low resolution synthesis calculations more apparent, so it's not always a bonus.
-
-Another factor which is important for Mozzi's operation is that with AUDIO_RATE
-being a power of two, some internal calculations can be highly optimised for
-speed.
-
-In STANDARD and STANDARD_PLUS modes, the sample resolution is 488,
-which provides some headroom above the 8 bit table resolution currently used by
-the oscillators. You can look at the TimerOne library for more info about how

-STANDARD / STANDARD_PLUS
----------------
-Use \#define AUDIO_MODE STANDARD_PLUS in Mozzi/config.h to select this
-output configuration, which is nearly 9 bit sound (-244 to 243) at 16384 Hz sample rate (AUDIO_RATE) and
-32768 Hz PWM rate. It uses Timer 1 for PWM and the sample updating routine (as an interrupt).
-
-STANDARD is obsolete now, replaced by STANDARD_PLUS which is the default audio mode.
-STANDARD mode uses 16384 Hz PWM rate with an output interrupt at the same frequency.
-Some people can hear the PWM carrier frequency as an annoying whine.
-
-STANDARD_PLUS mode uses 32768 Hz PWM rate, so the PWM carrier is out of hearing range.
-In this mode every alternate interrupt is used for the sample update (unless you /#define AUDIO_RATE 32768 in mozzi_config.h),
-which makes it slightly less efficient than STANDARD, but almost always better.
-
-Advantages: Only uses one timer for audio, and one output pin.
-Disadvantages: low dynamic range.

-----
-Use \#define AUDIO_MODE HIFI in Mozzi/config.h to set the audio mode to HIFI for output 14 bit sound at 16384 Hz sample rate and 125kHz PWM rate.
-The high PWM rate of HIFI mode places the carrier frequency beyond audible range.
-
-Also, 14 bits of dynamic range in HIFI mode provides more definition than the nearly 9 bits in STANDARD_PLUS mode.
-HIFI mode takes about the same amount of processing time as STANDARD_PLUS mode, and should sound clearer and brighter.
-However, it requires an extra timer to be used on the Arduino, which could increase the chances of
-conflicts with other libraries or processes if they rely on Timer 2.
-
-Timer 1 is used to provide the PWM output at 125kHz.
-Timer 2 generates an interrupt at AUDIO_RATE 16384 Hz, which sets the Timer1 PWM levels.
-HIFI mode uses 2 output pins, and sums their outputs with resistors, so is slightly less convenient for
-rapid prototyping where you could listen to STANDARD_PLUS mode by connecting the single output pin
-directly to a speaker or audio input (though a resistor of about 100 ohms is recommended).
-
-The resistors needed for HIFI output are 3.9k and 499k, with 0.5% or better tolerance.
-If you can only get 1% resistors, use a multimeter to find the most accurate.
-Use two 1M resistors in parallel if you can't find 499k.
-
-On 328 based Arduino boards, output is on Timer1, with the high byte on Pin 9 and low byte on Pin 10.
-Add the signals through a 3.9k resistor on high byte pin (9) and 499k resistor on low byte pin (10).
-Also, a 4.7nF capacitor is recommended between the summing junction of the resistors and ground.
-
-This dual PWM technique is discussed on http://www.openmusiclabs.com/learning/digital/pwm-dac/dual-pwm-circuits/
-Also, there are higher quality output circuits are on the site.
-
-Advantages: should be higher quality sound than STANDARD_PLUS mode.  Doesn't need a notch filter on
-the audio signal (like STANDARD which is now obsolete) because the carrier frequency is out of hearing range.
-
-Disadvantages: requires 2 pins, 2 resistors and a capacitor, so it's not so quick to set up compared
-to a rough, direct single-pin output in STANDARD_PLUS mode.

-Pins and where to put the resistors on various boards for HIFI mode.
-Boards tested in HIFI mode have an x, though most of these have been tested in STANDARD_PLUS mode

+ *
+ * The settings in the following section applies to the ESP32 architecture.
+ *
+ * It is generally not recommended to change anything, here, unless you really know, what you are doing and/or
+ * are willing to rough it out by yourself.
+ *
+********************************************************************************************************************************/
+
+
+/** @ingroup hardware
+ * @page hardware_esp32 Mozzi on ESP32-based boards.
+ *
+ * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *   - MOZZI_OUTPUT_PDM_VIA_I2S
+ *   - MOZZI_OUTPUT_I2S_DAC
+ *   - MOZZI_OUTPUT_INTERNAL_DAC
+ *
+ * The default mode is @ref esp32_internal_dac .
+ *
+ * @note
+ * This port really does not currently come with a PWM mode!
+ *
+ * @section esp32_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
+ * The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used.
+ * In a mono configuration, both pins output the same sample.
+ *
+ * TODO: We could really use this to hack in a 2 PIN mode!
+ *
+ * @note
+ * The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that.
+ *
+ * Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:
+ *
+ * @code
+ * #define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)
+ * @endcode
+ *
+ * @section esp32_i2s_dac MOZZI_OUTPUT_I2S_DAC
+ * This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins
+ * of one I2S interface. Presumably, any pins qualify, and you can configure this using:
+ * @code
+ * #define MOZZI_I2S_PIN_BCK  ... // (default: 26)
+ * #define MOZZI_I2S_PIN_WS   ... // (default: 15)
+ * #define MOZZI_I2S_PIN_DATA ... // (default: 33)
+ * #define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)
+ * @endcode
+ *
+ * See the note above (@ref esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!
+ *
+ * As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h".
+ * This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!
+ *
+ * @section esp32_pdm_via_i2s MOZZI_OUTPUT_PDM_VIA_I2S
+ * This mode uses the same setup as @ref esp32_i2s_dac, but rather than using an external DAC, the communication signal itself is modulated in PDM
+ * (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and
+ * WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.
+ *
+ * Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks
+ * of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.
+ *
+ * @section esp32_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ * See @ref external_audio

Subject: [PATCH 046/215] Temporarily bring back mozzi_config.h to allow
 intermediate testing

Fix some bits in AVR in reaction to that. Seems to work overall, however.

+ *
+ * The settings in the following section applies to the ESP8266 architecture.
+ *
+ * It is generally not recommended to change anything, here, unless you really know, what you are doing and/or
+ * are willing to rough it out by yourself.

+********************************************************************************************************************************/

+
+/** @ingroup hardware
+ * @page hardware_esp8266 Mozzi on ESP32-based boards.
+ *
+ * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *   - MOZZI_OUTPUT_PDM_VIA_I2S
+ *   - MOZZI_OUTPUT_PDM_VIA_SERIAL
+ *   - MOZZI_OUTPUT_I2S_DAC
+ *
+ * The default mode is @ref esp8266_pdm_via_serial .
+ *
+ * @note
+ * This port really does not currently come with a PWM mode!
+ *
+ * @section esp8266_pdm_via_serial MOZZI_OUTPUT_PDM_VIA_SERIAL
+ * Output is coded using pulse density modulation, and sent via GPIO2 (Serial1 TX).
+ *   - This output mode uses timer1 for queuing audio sample, so that timer is not available for other uses.
+ *   - Note that this mode has slightly lower effective analog output range than @ref esp8266_pdm_via_i2s, due to start/stop bits being added to the output stream.
+ *   - Supports mono output, only, pins not configurable.
+ *
+ * The option @ref MOZZI_PDM_RESOLTUON (default value 2, corresponding to 64 ones and zeros per audio sample) can be used to adjust the output resolution.
+ * Obviously higher values demand more computation power.
+ *
+ * @section esp8266_pdm_via_serial MOZZI_OUTPUT_PDM_VIA_I2S
+ * Output is coded using pulse density modulation, and sent via the I2S pins. The I2S data out pin (GPIO3, which is also "RX") will have the output,
+ * but *all* I2S output pins (RX, GPIO2 and GPIO15) will be affected. Mozzi tries to set GPIO2 and GPIO15 to input mode, and *at the time of this writing*, this allows
+ * I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Ground). However, it seems safest to assume that this mode may not be useable on boards where
+ * GPIO2 or GPIO15 are not available as output pins.
+ *
+ * Supports mono output, only, pins not configurable.
+ *
+ * Resolution may be controlled using MOZZI_PDM_RESOLUTION (see above; default value is 2).
+ *
+ * @section esp8266_i2s_dac MOZZI_OUTPUT_I2S_DAC
+ * Output is sent to an external DAC (such as a PT8211), digitally coded. This is the only mode that supports stereo (@ref MOZZI_AUDIO_CHANNELS). It also needs the least processing power.
+ * The pins cannot be configured (GPIO3/RX, GPIO2, and GPIO15).
+ *
+ * @section esp8266_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM

+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *   - MOZZI_OUTPUT_PDM_VIA_SERIAL
+ *   - MOZZI_OUTPUT_INTERNAL_DAC
+ *
+ * The default mode is @ref mbed_internal_dac .
+ *
+ * @section mbed_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
+ * This uses the inbuild DAC on the board. The default is setting is appropriate for the Arduino Giga: 12 bits going to A13 (3.5mm jack connector's tip),
+ * and in stereo mode to pin A12 (3.5mm jack connector's first ring) additionally.
+ *
+ * For other boards is may be appropriate to customize:
+ * @code
+ * #define MOZZI_AUDIO_PIN_1   ...   // mono / left channel; default: A13
+ * #define MOZZI_AUDIO_PIN_1   ...   // stereo only: right channel; default: A12
+ * #define MOZZI_AUDIO_BITS    ...   // default is 12
+ * @endcode
+ *
+ * @section mbed_pdm_via_serial MOZZI_PDM_VIA_SERIAL
+ * Returns a pulse-density modulated (mono only) signal on one of the hardware UARTs of the board (Serial ports). Default is using the SERIAL2, on pin D18.
+ * You can confiugre the pins to use, but it must be connected to a hardware UART. Output is written to the TX pin, only, but the RX pin needs to be
+ * claimed as well. Beware of confusing pinout labelling, for instance SERIAL2_TX iss labelled "TX1" on the Arduino Giga. The audio resolution can be enhanced
+ * using @ref MOZZI_PDM_RESOLUTION, which is described in more detail here: @esp32_pdm_via_i2s .
+ *
+ * Configuration options:
+ * @code
+ * #define MOZZI_SERIAL_PIN_TX ...    // default: SERIAL2_TX
+ * #define MOZZI_SERIAL_PIN_RX ...    // *must* specify the matching one, if customizing the above; default: SERIAL2_RX

+ * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *   - MOZZI_OUTPUT_INTERNAL_DAC
+ *
+ * The default mode is @ref renesas_internal_dac. Further modes may be added in the future.
+  - Because this board has an on-board DAC (A0), but only one, STEREO is not implemented and Mozzi uses this pin. Usage of other pins using PWM for instance is not implemented yet.
+  - Two timers are claimed by Mozzi when using the on-board DAC, one when using `EXTERNAL_AUDIO_OUTPUT`.
+  - `mozziAnalogRead()` returns values in the Renesas' full ADC resolution of 0-16384 rather than AVR's 0-1023. *This might change in the near future for speed purposes.*
+
+ * @section renesas_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
+ * This uses the inbuild DAC on the board on pin A0. Mono output only, and the pin is not configurable. Audio resolution is also fixed at 12 bits (which is what the board supports).
+ *
+ * This mode claims two timers (but it is not hardcoded, which ones).
+ *
+ * @section renesas_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ * MOZZI_OUTPUT_EXTERNAL_TIMED claimes one timer, MOZZI_OUTPUT_EXTERNAL_CUSTOM does not claim any timer.

+*  * The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:
+*    - Some boards use dedicated cores (e.g. Arduino Giga / Portenta @ref hardware_mbed) etc. For those, see the relevant sections (if we support them).
+*    - There is a series of libmaple-based cores, including [Roger Clark's libmaple-based core](https://github.com/rogerclarkmelbourne/Arduino_STM32). These are highly optimized,
+*      and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation
+*      via the Arduino Board Manager, and they do not currently seem actively maintained.
+*      For using these with Mozzi, see @ref hardware_stm32_maple
+*    - A generic Arduino core for STM32 is the [STM32duino core](https://github.com/stm32duino/Arduino_Core_STM32). It supports a huge step of boards, and seems to have offical
+*      backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what
+*      the libmaple cores above were known by (don't blame Mozzi for this mess!).

-*
-*  * The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:
-*    - Some boards use dedicated cores (e.g. Arduino Giga / Portenta @ref hardware_mbed) etc. For those, see the relevant sections (if we support them).
-*    - There is a series of libmaple-based cores, including [Roger Clark's libmaple-based core](https://github.com/rogerclarkmelbourne/Arduino_STM32). These are highly optimized,
-*      and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation
-*      via the Arduino Board Manager, and they do not currently seem actively maintained.
-*      For using these with Mozzi, see @ref hardware_stm32_maple
-*    - A generic Arduino core for STM32 is the [STM32duino core](https://github.com/stm32duino/Arduino_Core_STM32). It supports a huge step of boards, and seems to have offical
-*      backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what
-*      the libmaple cores above were known by (don't blame Mozzi for this mess!).
-*      For using this with Mozzi, see @ref hardware_stm32duino

- * Standard pulse width modulated output to one (mono) or two (stereo, see @ref MOZZI_AUDIO_CHANNELS) GPIO pins. Default pinout: PA8 (mono/left), PA9 (right channel in stereo).

- * // For stereo, only:
- * #define MOZZI_AUDIO_PIN_2       ...  // Right channel output pin. This *must* be connected to the same hardware timer as MOZZI_AUDIO_PIN_1 ! Default: PA9
- * @endcode
- *
- * @section stm32duino_pwm MOZZI_OUTPUT_2PIN_PWM
- * This mode is very similar to @ref stm32duino_pwm, but splitting output for a single channel across two GPIO pins for better resolution. For details on the required
- * hardware setup, and configuration tradeoffs, see @ref avr_2pin_pwm . Stereo output is not available in this mode.

 ## Hardware specific notes
 
-### STM32
-The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:
-- Some boards use dedicated cores (e.g. Arduino Giga / Protenta) etc. For those, see the relevant sections (if we support them)
-- There is a series of libmaple-based cores, including [Roger Clark's libmaple-based core](https://github.com/rogerclarkmelbourne/Arduino_STM32). These are highly optimized, and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation via the Arduino Board Manager, and they do not currently seem actively maintained.
-- A generic Arduino core for STM32 is the [STM32duino core](https://github.com/stm32duino/Arduino_Core_STM32). It supports a huge step of boards, and seems to have offical backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what the libmaple cores above were known by (don't blame Mozzi for this mess!).
-
-Mozzi supports both of the latter, but currently not at the same level of completeness.

-#### STM32 libmaple based
-port by Thomas Friedrichsmeier
-
-Compiles for and runs on a STM32F103C8T6 blue pill board, with a bunch of caveats (see below), i.e. on a board _without_ a
-real DAC. Should probably run on any other board supported by [Roger Clark's libmaple-based core](https://github.com/rogerclarkmelbourne/Arduino_STM32) (although this theory is untested).
-
-*NOTE* that at the time of this writing, [Stev Strong's slightliy more recent fork of this core](https://github.com/stevstrong/Arduino_STM32/) does *not* work with
-Mozzi, apparently due to a bug in pwmWrite().
-
-- You will need a very recent checkout of the Arduino_STM32 repository, otherwise compilation will fail.
-- Audio output is to pin PB8, by default (HIFI-mode: PB8 and PB9)
-- If you want to use MIDI, be sure to replace "MIDI_CREATE_DEFAULT_INSTANCE()" with "MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI)" (or Serial2)
-- Timers 4 (PWM output), and 2 (audio rate) are used by default.
-- The STM32-specific options (pins, timers) can be configured in AudioConfigSTM32.h
-- Default audio resolution is currently set to 10 bits, which yields 70khZ PWM frequency on a 72MHz CPU. HIFI mode is 2*7bits at up to 560Khz (but limited to 5 times audio rate)
-- AUDIO_INPUT is completely untested (but implemented in theory)
-- Note that AUDIO_INPUT and mozziAnalogRead() return values in the STM32's full ADC resolution of 0-4095 rather than AVR's 0-1023.
-- twi_nonblock is not ported

-[STM32duino core](https://github.com/stm32duino/Arduino_Core_STM32) (although this theory is untested).

-achievable, and whether the desired output pins are PWM capable.

-- Audio output is PWM-based to pin PA8, by default (HIFI-mode: PA8 and PA9)

-- The STM32-specific options (pins, timers) can be configured in AudioConfigSTM32duino.h
-- Default audio resolution is currently set to 10 bits, which yields 70khZ PWM frequency on a 72MHz CPU. IMPORTANT: Should your CPU be slower, you will need to lower the audio resolution!
-- HIFI mode is 2*7bits at up to 560Khz with a 72MHz CPU (but limited to 5 times audio rate)
-- Analog input implementation is somewhat experimental, and may not be able to service a whole lot of pins (contributions welcome)
-- AUDIO_INPUT is completely untested (but implemented in theory)

-Some of the differences for Teensy 3.* which will affect users include:
-
-- On Teeensy 3.0/3.1/3.2/Audio output is on pin A14/DAC, in STANDARD or STANDARD_PLUS audio modes.
-    These modes are identical on Teensy 3.0/3.1/3.2, as the output is via DAC rather than PWM.
-- Output is 12 bits in STANDARD and STANDARD_PLUS modes, up from nearly 9 bits for Atmel based boards. HIFI audio, which works by summing two output pins, is not available on Teensy 3.0/3.1.
-- twi_nonblock code by Marije Baalman for non-blocking I2C is not compatible with Teensy 3.0/3.1/3.2.

 - The audio output resolution is always 16 bits on this platform, _internally_. Thus, in updateAudio(), you should scale your output samples to a full 16 bit range. The effective number of output bits cannot easily
   be quantified, due to PDM coding.
 - audioHook() calls `yield()` once for every audio sample generated. Thus, as long as your audio output buffer does not run empty, you should not need any additional `yield()`s inside `loop()`.

  *
  * @note
  * It is generally safe to leave the Mozzi Configuration unchanged, and that's very much recommended _until_ you have a very specific need to customize something.
+ * Contrary to past versions of Mozzi, all configuration options have a (usually sensible) default value, so you do not have to configure _anything_, unless you
+ * actually want to change something.
+ *
+ * Configuring Mozzi is mostly done using various preprocessor definitions. This approach is used to move as much of the processing involved to compile time, in order
+ * to save Flash, RAM, and CPU use at runtime. This section lists various global options, but in addition, most ports allow additional hardware dependent
+ * configuration options. See @ref hardware.
+ *
+ * Several configuration examples are provided in the "config" folder of the Mozzi sources. You may want to look at these, first.
  *
- * Usage:
- *   - either:
- *      1. Copy this file to your sketch directory
- *      2. Adjust as desired, uncommenting only those options that you intend to change from their default value
- *      3. #include it in your sketch **before** #include <MozziGuts.h>
- *         (must be included in each .cpp-file using Mozzi inside your sketch, if more than one)
- *   - or:
- *      1. Copy only the sections you want to customize
- *      2. Put them near the top of your sketch **before** #include <MozziGuts.h>
- *         (should your sketch have more than one .cpp-file, identical options need to be set before each #include <MozziGuts.h>)
- * 
  * TODO: Fix and complete Doxygen coverage

-/** @ingroup hardware
- * @page hardware_avr Mozzi on classic Arduino, Teensy (2.x and 3.x), Arduino Mega, and other 8 bit "AVR"/ATMEGA architecture boards
- *
- * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware. In all cases, Timer 1 is claimed, and
- * is not available for any other purpose:
- *   - MOZZI_OUTPUT_PWM
- *   - MOZZI_OUTPUT_2PIN_PWM
- *   - MOZZI_OUTPUT_EXTERNAL_TIMED
- *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
- *
- * In all cases, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose.
- *
- * @section avr_pwm MOZZI_OUTPUT_PWM
- * For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured
- * within this tight limit. In particular, the default setup on the
- * Arduino UNO is:
- *    - Mono: Pin 9 -> configurable using MOZZI_AUDIO_PIN_1
- *    - Stereo: Pin 9 (left) and Pin 10 (right)  -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2
- * For pinouts on other boards, refer to config/known_16bit_timers.
- *
- * Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.
- *
- * The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution
- * currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.
- *
- * @section avr_2pin_pwm  MOZZI_OUTPUT_2PIN_PWM
- * In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for
- * much better dynamic range, providing much more definition than can be achieved using @ref avr_pwm , while using
- * only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see @ref
- * MOZZI_PWM_RATE), which is well beyond the audible range.
- *
- * On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility
- * problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient
- * for rapid prototyping:
- *
- * In hardware, add the two signals through a 3.9k resistor on the "high" pin and 499k resistor on "low" pin.
- * Use 0.5% resistors or select the most accurate from a batch. It is further recommended to place a 4.7nF capacitor between the summing junction
- * of the resistors and ground. This is discussed in much more detail on http://www.openmusiclabs.com/learning/digital/pwm-dac/dual-pwm-circuits/
- * Also, there are higher quality output circuits are on the site.
- *
- * On the classic Arduino Uno, the default pinout in this mode is:
- *    - Pin 9 (high bits) and Pin 10 (low bits) -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW
- *
- * Here is table of the default pins on some other boards. Rows with an x on it have actually been tested (and importantly, the outcome recoreded;
- * input welcome on further boards.)

- * In a mono configuration, both pins output the same sample.
- *
- * TODO: We could really use this to hack in a 2 PIN mode!
- *
- * @note
- * The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that.
- *
- * Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:
- *
- * @code
- * #define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)
- * @endcode
- *
- * @section esp32_i2s_dac MOZZI_OUTPUT_I2S_DAC
- * This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins
- * of one I2S interface. Presumably, any pins qualify, and you can configure this using:
- * @code
- * #define MOZZI_I2S_PIN_BCK  ... // (default: 26)
- * #define MOZZI_I2S_PIN_WS   ... // (default: 15)

- * See the note above (@ref esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!
- *
- * As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h".
- * This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!
- *
- * @section esp32_pdm_via_i2s MOZZI_OUTPUT_PDM_VIA_I2S
- * This mode uses the same setup as @ref esp32_i2s_dac, but rather than using an external DAC, the communication signal itself is modulated in PDM
- * (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and
- * WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.
- *
- * Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks
- * of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.

-port by Adrian Freed
-
-- Currently, only output on the inbuilt DAC (pin DAC0) is supported. So, obviously, boards without a DAC are not yet convered (in theory you can still use EXTERNAL_AUDIO_OUTPUT)
-- Output resolution is fixed at 10 bits. If your board supports more, configure in AudioConfigSAMD21.h
-- mozziAnalogRead() and AUDIO_INPUT are not implemented (contributions welcome)
-- We don't have a lot of data, which boards this port has been tested on. Success or not, let us know, if you are using Mozzi on SAMD21 boards
-
-### ESP8266
-port by Thomas Friedrichsmeier
-
-- Since flash memory is not built into the ESP8266, but connected, externally, it is much too slow for keeping wave tables, audio samples, etc. Instead, these are kept in RAM on this platform.
-- Asynchronous analog reads are not implemented. `mozziAnalogRead()` relays to `analogRead()`.
-- AUDIO_INPUT is not implemented.
-- twi_nonblock is not ported
-- Several audio output modes exist, the default being PDM_VIA_SERIAL (configurable in AudioConfigESP.h):
-  - PDM_VIA_SERIAL: Output is coded using pulse density modulation, and sent via GPIO2 (Serial1 TX).
-    - This output mode uses timer1 for queuing audio sample, so that timer is not available for other uses.
-    - Note that this mode has slightly lower effective analog output range than PDM_VIA_I2S, due to start/stop bits being added to the output stream.
-  - PDM_VIA_I2S: Output is coded using pulse density modulation, and sent via the I2S pins. The I2S data out pin (GPIO3, which is also "RX") will have the output,
-  but *all* I2S output pins (RX, GPIO2 and GPIO15) will be affected. Mozzi tries to set GPIO2 and GPIO15 to input mode, and *at the time of this writing*, this allows
-  I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Gnd). However, it seems safest to assume that this mode may not be useable on boards where
-  GPIO2 or GPIO15 are not available as output pins.
-  - EXTERNAL_DAC_VIA_I2S: Output is sent to an external DAC (such as a PT8211), digitally coded. This is the only mode that supports STEREO. It also needs the least processing power.
-- There is no "HIFI_MODE" in addition to the above output options. For high quality output, either use an external DAC, or increase the PDM_RESOLUTION value.
-- Note that the ESP8266 pins can output less current than the other supported CPUs. The maximum is 12mA, with a recommendation to stay below 6mA.
-  - WHEN CONNECTING A HEADPHONE, DIRECTLY, USE APPROPRIATE CURRENT LIMITING RESISTORS (>= 500Ohms).
-- _Any_ WiFi-activity can cause severe spikes in power consumption. This can cause audible "ticking" artifacts, long before any other symptoms.
-  - If you do not require WiFi in your sketch, you should turn it off, _explicitly_, using `WiFi.mode(WIFI_OFF)`.
-  - A juicy enough, well regulated power supply, and a stabilizing capacitor between VCC and Gnd can help a lot.
-  - As the (PDM) output signal is digital, a single (fast!) transistor can be used to amplify it to an independent voltage level.
-- The audio output resolution is always 16 bits on this platform, _internally_. Thus, in updateAudio(), you should scale your output samples to a full 16 bit range. The effective number of output bits cannot easily
-  be quantified, due to PDM coding.
-- audioHook() calls `yield()` once for every audio sample generated. Thus, as long as your audio output buffer does not run empty, you should not need any additional `yield()`s inside `loop()`.

-### ESP32
-port by Dieter Vandoren and Thomas Friedrichsmeier
-
-- Since flash memory is not built into the ESP32, but connected, externally, it is much too slow for keeping wave tables, audio samples, etc. Instead, these are kept in RAM on this platform.
-- Asynchronous analog reads are not implemented. `mozziAnalogRead()` relays to `analogRead()`.
-- AUDIO_INPUT is not implemented.
-- twi_nonblock is not ported
-- Currently, three audio output modes exist, the default being INTERNAL_DAC (configurable in AudioConfigESP32.h). *The configuration details may still be subject to change; please be prepared to make some minimal adjustments to your code, when upgrading Mozzi*:
-  - INTERNAL_DAC: Output using the built-in DAC on GPIO pins 25 and 26.
-    - 8 bits resolution, mono (on both pins) or stereo
-    - For simplicity of code, both pins are always used, even in mono output mode
-  - PT8211_DAC: Output is sent via I2S in a format suitable for the PT8211 external EXTERNAL_DAC
-    - 16 bits resolution, mono or stereo. Remember to shift your audio accordingly.
-    - Output pins can be configured in AudioConfigESP32.h. Default is BCK: 26, WS: 15, DATA: 33
-  - PDM_VIA_I2S: Output is converted using pulse density modulation, sent to the I2S data pin. No external hardware needed.
-    - 16 bits resolution. Remember to shift your audio accordingly.
-    - Output (DATA) pin can be configured in AudioConfigESP32.h. Default 33. Note that the BCK and WS pins are also used in this mode.
-    - The PDM_RESOLUTION parameter can be used to reduce noise at the cost of more CPU power.
-    - Mono, only.
-- "HIFI_MODE" is not currently implemented, but could conceivably be realized for the INTERNAL_DAC mode. Patches welcome.
-- WIFI-activity not yet tested, but likely the same notes as for ESP8266 apply. Consider turning off WIFI.
-- The implementation of audioTicks() may be slightly inaccurate on this platform.
-
-### RP2040 (Raspberry Pi Pico)
-port by Thomas Friedrichsmeier
-
-Compiles and runs using [this core](https://github.com/earlephilhower/arduino-pico). Can probably be ported to the Mbed core for RP2040, relatively easily, as it relies mostly
-on the RP2040 SDK API. Tested on a Pi Pico.
-
-- This is a recent addition, implementation details may still change (currently just PWM driven by a timer; this may be worth changing to a DMA driven output)
-- Wavetables and samples are not kept in progmem on this platform. While apparently speed (of the external flash) is not much of an issue, the data always seems to be copied into RAM, anyway.
-- Currently, two audio output modes exist (configurable in AudioConfigRP2040.h) in addition to using an user-defined `audioOutput` function, with the default being PWM_VIA_BARE_CHIP:
-  - PWM_VIA_BARE_CHIP: PWM audio output on pin 0, by default, with 11 bits default output resolution
-    - One hardware timer interrupt and one DMA channel are claimed (number not hardcoded), a non-exclusive handler is installed on DMA_IRQ_0.
-    - HIFI_MODE not yet implemented (although that should not be too hard to do).
-  - EXTERNAL_DAC_VIA_I2S: I2S output to be connected to an external DAC
-    - 16 bits resolution by default (configurable in AudioConfigRP2040.h), 8, 16, 24 (left aligned) and 32 resolution are available.
-    - Both plain I2S and LSBJ_FORMAT (for the PT8211 for instance) are available (configurable in AudioConfigRP2040.h), default is LSBJ.
-    - Outputs pins can be configured in AudioConfigRP2040.h. Default is BCK: 20, WS: 21, DATA: 22.
-    - Two DMA channels are claimed (numbers not hardcoded), non-exclusive handlers are installed on DMA_IRQ_0.
-    - At the time of writing, LSBJ is only available with github arduino-pico core.
-- Note that AUDIO_INPUT and mozziAnalogRead() return values in the RP2040's full ADC resolution of 0-4095 rather than AVR's 0-1023.
-- twi_nonblock is not ported
-- Code uses only one CPU core
-
-### Arduino Giga/MBED
-port by Thomas Friedrichsmeier & Thomas Combriat
-
-Compiles and runs using Arduino's standard and Arduino_AdvancedAnalog libraries. This port is still **experimental**, testing reveals some instabilities for some configurations (in particular with USE_AUDIO_INPUT) that are under active investigations.
-
-- This port is not complete yet, in particular:
-  - Asynchroneous analog reads are not implemented (yet), `mozziAnalogRead()` relays to `analogRead()`.
-  - HIFI mode is not implemented.
-- In addition to using an user-defined `audioOutput()` by setting `EXTERNAL_AUDIO_OUTPUT` to `true` in mozzi_config.h, two bare chip output modes exist (configurable in AudioConfigMBED.h):
-  - INTERNAL_DAC: uses the DAC present on the board and outputs by default on pin A13 (3.5mm jack connector's tip). Stereo mode uses pin A12 (3.5mm jack connector's first ring) additionally.
-  - PDM_VIA_SERIAL: returns a pulse-density modulated signal on one of the hardware UART of the board (Serial ports). Default is using the SERIAL2, on pin D18.
-- This port should support other MBED based Arduino boards like the Arduino Portenta, in *theory*. It has only been tested on the giga but feedbacks are welcome!
-
-### Arduino Uno R4
-port by Thomas Combriat
-
-Compiles and runs using Arduino's standard library (Renesas 0.8.7 at the time of this writing).
-
-- A few particularities:
-
-  - Because this board has an on-board DAC (A0), but only one, STEREO is not implemented and Mozzi uses this pin. Usage of other pins using PWM for instance is not implemented yet.
-  - Two timers are claimed by Mozzi when using the on-board DAC, one when using `EXTERNAL_AUDIO_OUTPUT`.
-  - `mozziAnalogRead()` returns values in the Renesas' full ADC resolution of 0-16384 rather than AVR's 0-1023. *This might change in the near future for speed purposes.*
+## Hardware compatibility and hardware specific notes
+
+While originating on the 8 bit AVR based "classic Arduino" boards, Mozzi supports a wide variety of different MCUs, these days, including:
+  - Classic AVR boards: Arduino Uno, Duemilanove, Nano, Nano 33, Pro Mini, Leonardo, Mega, many others, and countless clones, Teensy 1 and 2.x, ...
+  - Various Teensy 3.x boards: Teensy 3.0/3.1/3.2/3.4/3.5/LC
+  - Teensy 4.x boards: Teensy 4.0 and 4.1 are known to work, future boards stand good chances of working with Mozzi out of the box
+  - STM32-based boards: Confusingly, several popular Arduino cores exist for these MCUs - and Mozzi supports several. Refer to the documentation
+    linked below. Mozzi has been tested on the popule STM32F1 "blue pill" and STM32F4 "black pill" boards, but should support a very wide range
+    of further boards out of the box.
+  - SAMD21-based boards: Tested on the Arduino Circuitplayground M0, expect to work on others, too.
+  - ESP8266: Should run on the whole range of boards, including the minimal ESP-01
+  - ESP32: Should run on the wohle range of boards
+  - Arduiono Giga/MBED: The Arduino Giga, and - in untested theory - the Arduion Portenta
+  - RP2040: The Raspberry Pi Pico and other boards using RP2040
+  - Arduino Uno R4: The new Uno, based on a 32-bit Renesas MCU
+
+Since the hardware capatibilies of these boards are vastly different, the ports, too, differ in their internals and their capabilities. Importantly,
+of course, they also differ in what pin(s) are used for audio output by default. Refer to the [Hardware Section of the Documentation](https://sensorium.github.io/Mozzi/doc/html/group__hardware.html) for the details
+applicable to your hardware.

+ * This is the original "port" of Mozzi, and thus very elaborate. The main challenges on this platform, compared to other MCUs, are limitations in
+ * flash, RAM, and CPU power.
+ *
+ * @section avr_output Output modes
+ * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware. In all cases, Timer 1 is claimed, and
+ * is not available for any other purpose:
+ *   - MOZZI_OUTPUT_PWM
+ *   - MOZZI_OUTPUT_2PIN_PWM
+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *
+ * In all cases, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose.
+ *
+ * @section avr_pwm MOZZI_OUTPUT_PWM
+ * For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured
+ * within this tight limit. In particular, the default setup on the
+ * Arduino UNO is:
+ *    - Mono: Pin 9 -> configurable using MOZZI_AUDIO_PIN_1
+ *    - Stereo: Pin 9 (left) and Pin 10 (right)  -> configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2
+ * For pinouts on other boards, refer to config/known_16bit_timers.
+ *
+ * Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.
+ *
+ * The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution
+ * currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.
+ *
+ * @section avr_2pin_pwm  MOZZI_OUTPUT_2PIN_PWM
+ * In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for
+ * much better dynamic range, providing much more definition than can be achieved using @ref avr_pwm , while using
+ * only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see @ref
+ * MOZZI_PWM_RATE), which is well beyond the audible range.
+ *
+ * On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility
+ * problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient
+ * for rapid prototyping:
+ *
+ * TODO: Move this bit to a dedicated page on output circuits?
+ * In hardware, add the two signals through a 3.9k resistor on the "high" pin and 499k resistor on "low" pin.
+ * Use 0.5% resistors or select the most accurate from a batch. It is further recommended to place a 4.7nF capacitor between the summing junction
+ * of the resistors and ground. This is discussed in much more detail on http://www.openmusiclabs.com/learning/digital/pwm-dac/dual-pwm-circuits/
+ * Also, there are higher quality output circuits are on the site.

+/** @ingroup hardware
+ * @page hardware_esp32 Mozzi on ESP32-based boards.
+ *
+ * port by Dieter Vandoren and Thomas Friedrichsmeier
+ *
+ * @section esp32_status Port status and notes
+ *   - Since flash memory is not built into the ESP32, but connected, externally, it is much too slow for keeping wave tables, audio samples, etc. Instead, these are kept in RAM on this platform.
+ *   - Asynchronous analog reads are not implemented. `mozziAnalogRead()` relays to `analogRead()`. @ref MOZZI_AUDIO_INPUT is not implemented
+ *   - twi_nonblock is not ported
+ *   - WIFI-activity not yet tested, but likely the same notes as for ESP8266 apply, i.e. @em any Wifi activity is likely to introdcue considerable nose. Consider turning off WIFI.
+ *   - The implementation of audioTicks() may be slightly inaccurate on this platform.
+ *
+ * @section esp32_output Output modes
+ * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:
+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *   - MOZZI_OUTPUT_PDM_VIA_I2S
+ *   - MOZZI_OUTPUT_I2S_DAC
+ *   - MOZZI_OUTPUT_INTERNAL_DAC
+ *
+ * The default mode is @ref esp32_internal_dac .
+ *
+ * @section esp32_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
+ * The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used.
+ * In a mono configuration, both pins output the same sample.
+ *
+ * TODO: We could really use this to hack in a 2 PIN mode!
+ *
+ * @note
+ * The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that.
+ * Check a detailed pinout diagram, if in any doubt.
+ *
+ * Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:
+ *
+ * @code
+ * #define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)
+ * @endcode
+ *
+ * @section esp32_i2s_dac MOZZI_OUTPUT_I2S_DAC
+ * This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins
+ * of one I2S interface. Presumably, any pins qualify, and you can configure this using:
+ * @code
+ * #define MOZZI_I2S_PIN_BCK  ... // (default: 26)
+ * #define MOZZI_I2S_PIN_WS   ... // (default: 15)
+ * #define MOZZI_I2S_PIN_DATA ... // (default: 33)
+ * #define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)
+ * @endcode
+ *
+ * See the note above (@ref esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!
+ *
+ * As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h".
+ * This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!
+ *
+ * @section esp32_pdm_via_i2s MOZZI_OUTPUT_PDM_VIA_I2S
+ * This mode uses the same setup as @ref esp32_i2s_dac, but rather than using an external DAC, the communication signal itself is modulated in PDM
+ * (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and
+ * WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.
+ *
+ * Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks
+ * of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.
+ *
+ * @section esp32_external MOZZI_OUTPUT_EXTERNAL_TIMED and MOZZI_OUTPUT_EXTERNAL_CUSTOM

+ *   - twi_nonblock is not ported
+ *   - Note that the ESP8266 pins can output less current than the other supported CPUs. The maximum is 12mA, with a recommendation to stay below 6mA.
+ *      - WHEN CONNECTING A HEADPHONE, DIRECTLY, USE APPROPRIATE CURRENT LIMITING RESISTORS (>= 500Ohms).
+ *   - _Any_ WiFi-activity can cause severe spikes in power consumption. This can cause audible "ticking" artifacts, long before any other symptoms.
+ *      - If you do not require WiFi in your sketch, you should turn it off, _explicitly_, using @code WiFi.mode(WIFI_OFF) @endcode.
+ *   - A juicy enough, well regulated power supply, and a stabilizing capacitor between VCC and Gnd can help a lot.
+ *   - As the (PDM) output signal is digital, a single (fast!) transistor can be used to amplify it to an independent voltage level.
+ *   - audioHook() calls `yield()` once for every audio sample generated. Thus, as long as your audio output buffer does not run empty, you should not need any additional `yield()`s inside `loop()`.
+ *
+ * @section esp8266_output Output modes
+ * The following audio modes (see @ref MOZZI_AUDIO_MODE) are currently supported on this hardware:

+ *   - MOZZI_OUTPUT_PDM_VIA_I2S
+ *   - MOZZI_OUTPUT_PDM_VIA_SERIAL
+ *   - MOZZI_OUTPUT_I2S_DAC
+ *
+ * The default mode is @ref esp8266_pdm_via_serial .
+ *
+ * @note
+ * This port really does not currently come with a PWM mode!
+ *
+ * @section esp8266_pdm_via_serial MOZZI_OUTPUT_PDM_VIA_SERIAL
+ * Output is coded using pulse density modulation, and sent via GPIO2 (Serial1 TX).
+ *   - This output mode uses timer1 for queuing audio sample, so that timer is not available for other uses.
+ *   - Note that this mode has slightly lower effective analog output range than @ref esp8266_pdm_via_i2s, due to start/stop bits being added to the output stream.
+ *   - Supports mono output, only, pins not configurable.
+ *
+ * The option @ref MOZZI_PDM_RESOLTUON (default value 2, corresponding to 64 ones and zeros per audio sample) can be used to adjust the output resolution.
+ * Obviously higher values demand more computation power.
+ *
+ * @section esp8266_pdm_via_serial MOZZI_OUTPUT_PDM_VIA_I2S
+ * Output is coded using pulse density modulation, and sent via the I2S pins. The I2S data out pin (GPIO3, which is also "RX") will have the output,
+ * but *all* I2S output pins (RX, GPIO2 and GPIO15) will be affected. Mozzi tries to set GPIO2 and GPIO15 to input mode, and *at the time of this writing*, this allows
+ * I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Ground). However, it seems safest to assume that this mode may not be useable on boards where
+ * GPIO2 or GPIO15 are not available as output pins.
+ *
+ * Supports mono output, only, pins not configurable.
+ *
+ * Resolution may be controlled using MOZZI_PDM_RESOLUTION (see above; default value is 2).
+ *
+ * @section esp8266_i2s_dac MOZZI_OUTPUT_I2S_DAC
+ * Output is sent to an external DAC (such as a PT8211), digitally coded. This is the only mode that supports stereo (@ref MOZZI_AUDIO_CHANNELS). It also needs the least processing power.

+ *
+ * This port is not complete yet, in particular:
+ *   - Asynchroneous analog reads are not implemented (yet), `mozziAnalogRead()` relays to `analogRead()`. (Note that @ref MOZZI_AUDIO_INPUT @em is implemented!)
+ *   - This port should support other MBED based Arduino boards like the Arduino Portenta, in *theory*, but the developer have only tested it on the Giga. Feedback welcome!

+ *   - MOZZI_OUTPUT_EXTERNAL_TIMED
+ *   - MOZZI_OUTPUT_EXTERNAL_CUSTOM
+ *   - MOZZI_OUTPUT_PDM_VIA_SERIAL
+ *   - MOZZI_OUTPUT_INTERNAL_DAC
+ *
+ * The default mode is @ref mbed_internal_dac .
+ *
+ * @section mbed_internal_dac MOZZI_OUTPUT_INTERNAL_DAC
+ * This uses the inbuild DAC on the board. The default is setting is appropriate for the Arduino Giga: 12 bits going to A13 (3.5mm jack connector's tip),
+ * and in stereo mode to pin A12 (3.5mm jack connector's first ring) additionally.
+ *
+ * For other boards is may be appropriate to customize:
+ * @code

+ * @endcode
+ *
+ * @section mbed_pdm_via_serial MOZZI_PDM_VIA_SERIAL
+ * Returns a pulse-density modulated (mono only) signal on one of the hardware UARTs of the board (Serial ports). Default is using the SERIAL2, on pin D18.
+ * You can confiugre the pins to use, but it must be connected to a hardware UART. Output is written to the TX pin, only, but the RX pin needs to be
+ * claimed as well. Beware of confusing pinout labelling, for instance SERIAL2_TX iss labelled "TX1" on the Arduino Giga. The audio resolution can be enhanced
+ * using @ref MOZZI_PDM_RESOLUTION, which is described in more detail here: @esp32_pdm_via_i2s .

  *
  * Mozzi provides support for audio ouput on a range of different boards and CPUs. This page is about the following related topics:
  *
@@ -10,30 +9,35 @@
  *
  * For all of these topics, it is helpful to have a basic understanding of the basic output steps in Mozzi:
  *
- * 1. Inside the loop() function in your sketch you call audioHook(). This function is responsible for calling updateAudio(), whenever there is room in the output buffer,
- *    adding the generated sample to the output buffer, calling updateControl() at an appropriate rate, and a few other details that are not important for this discussion.
+ * 1. Inside the loop() function in your sketch you call audioHook().
+ * 1a. If the audio output buffer is currently filled, this does nothing.
+ * 1b. Otherwise, this calls updateAudio(). The generated sample is then added to the audio output buffer. (Also, updateControl() will be called at an appropriate rate,
+ *     and a few other details that are not important for this discussion.)
  *
  * 2. A platform-specific timer is triggered at audio rate (usually), takes a sample from the output buffer and sends it to audioOutput().
  *
  * 3. The audioOutput() function - usually predefined inside Mozzi - takes care of sending the sample to the hardware.
- *    // TODO refer to @see external_audio for most of this, instead.
  *
- * This basic output pipeline can be customized in several ways. First, defining EXTERNAL_AUDIO_OUTPUT to true in mozzi_config.h will allow you to define your own audioOutput()
- * fuction. The library ships with some sample sketches for output to external DACs using this mechanism.
+ * These output steps are not always followed, however. Firstly, when using @ref external_audio output, the audioOutput() funtion is supplied by the user sketch,
+ * instead of Mozzi. @ref external_audio output.
  *
- * In some cases, you will additionally want to bypass Mozzis output buffer, for example, if your board, or your external DAC already comes with an efficient built-in buffer.
- * In this case, define BYPASS_MOZZI_OUTPUT_BUFFER to true. You will then have to provide a custom definition of canBufferAudioOutput(), returning true whenever your hardware
- * is ready toaccept a new sample of output. This is called from inside audioHook(), and whenever there is room for a new sample, it is generated and sent to audioOutput(),
- * immediately. In this case, should you need a timer running at AUDIO_RATE, you will have to set up one, yourself, if needed.
+ * Some ports will also want to bypass the Mozzi audio output buffer. For instance, an internal DAC may be addressable via an efficient DMA-connected
+ * buffer, already, and also have a built-in rate control. In this case, ports will internally set the define @ref BYPASS_MOZZI_OUTPUT_BUFFER to true. Such a port will
+ * have to provide a custom definition of canBufferAudioOutput(), returning true, whenever a new sample of output can be accepted. No timer at audio-rate is set up in this
+ * case.
  *
- * In custom code, setting BYPASS_MOZZI_OUTPUT_BUFFER does not make much sense without EXTERNAL_AUDIO_OUTPUT also set to true. However, some platform ports (e.g. ESP32) actually
- * use this combination, internally.
+ * Finally, the @ref external_audio output mode @ref MOZZI_OUTPUT_EXTERNAL_CUSTOM is essentially a combination of the two. Here, the user sketch needs to provide
+ * both audioOutput() and canBufferAudioOutput(). The latter is again called from audioHook(), and whenever it returns true, a new sample is generated and passed to
+ * audioOutput().
  *
+ * @section audio_shifting Platform specific audio resolution
  * Different output methods often support a different resolution of output samples. To provide best performance on slow boards, Mozzi expects your updateAudio() function to
  * return samples in exactly the width that is needed at the output stage. Thus, defining this naively, an updateAudio() function designed for 8 bit output will produce very
  * low volume output on a 16 bit DAC, while the other way around overflows will result in way too loud and heavily distored output. Fortunately, all that is needed to write
  * portable sketches is to specify how many bits your updateAudio() function provides. The (inline) functions in the AudioOutput namespace do just that. Using them makes sure
  * your audio output is shifted if, and as much as needed on all platforms.

Subject: [PATCH 070/215] Move auto random seeding to hardware specific
 implementation files

(This is expected to increase flash size, marginally, but the effect will mostly go
away once implementation and usage are once again in the same compilation unit.)

Subject: [PATCH 072/215] Restore the plain "int" overloads to rand().

When int is not an alias to intXY_t, compilers may be too stubborn to understand, which overload to use.
Conversely, having both an int16_t and and int overload is not possible on AVR (where the two _are_ an alias).

Subject: [PATCH 073/215] MozziGuts implementation is now included from
 MozziGuts.h (most important step for single compilation unit)

This required introduction of a private namespace, so that internals do not leak out and clash with user code.
That, in turn, meant changes all over the place.

  * @note
  * For compatibility reasons, the option AUDIO_RATE is automatically set to the same value as this option, and you will find some uses of that in old (pre Mozzi 2.0) code examples.
  * It is advised to use only MOZZI_AUDIO_RATE in new code, however.

 Moved headers:
  - Header files not meant for user inclusion have been moved to "internal"
  - New sketches should include "Mozzi.h", rather than "MozziGuts.h", thereby documenting, they have been written for Mozzi 2.0+

Subject: [PATCH 079/215] Trick doxygen into showing more of the existing
 documentation.

Doxygen still ignores quite a bit of existing stuff. Importantly, apparently, we need to @defgroup all groups before using them,
and define all documented preprocessor tokens (documenting them, alone, is not enough).

  - Since Mozzi (AVR-port) no longer uses Timer 0 since a long time, the corresponding library (utility/TimerZero.h) has now been removed, too.
    The Arduino functions delay(), millis(), micros() and delayMicroseconds() should now be usable in theory. That said,
    you should avoid these functions, as they are slow (or even blocking). For measuring time, refer

+/*  Example of simple and stereo synthesis,
+    using Mozzi sonification library with output to an A2DP sink
+    (i.e. a Bluetooth speaker / headphone).
+
+
+    IMPORTANT:
+    - This example requires the ESP32-A2DP library by Phil Schatzmann:
+    https://github.com/pschatzmann/ESP32-A2DP/
+    - This example works on ESP32, only
+    (Examples for other bluetooth-capable boards will follow, eventually.)
+    - You will want to adjust at least the "BLUETOOTH_DEVICE"-define, below!
+
+    Technical notes:
+    The BT-lib expects to read samples at its own pace, so we cannot
+    just "push" samples at the MOZZI_AUDIO_RATE, but rather they get
+    "pulled" via get_data_frames().
+
+    We therefore need a custom buffering scheme, i.e we select 
+    MOZZI_OUTPUT_EXTERNAL_CUSTOM as output mode, and keep an own, custom buffer
+    (which is visible to Mozzi via the two special functions
+    canBufferAudioOutput(), and audioOutput()).
+
+    Note that the BT default sample rate is 44100, which is not one of the powers
+    of two that Mozzi likes so much (32768 in this example). Ignoring this would
+    "work", but everything would essentially play too fast, resulting in an upward
+    frequency shift. To fix this, we use a very crude sample rate adjustment,
+    simply by repeating some of the frames to stay in sync.
+
+    Support for Bluetooth A2DP is also provided by the Espressif IDF, so this sketch *could*
+    be made to work without an external library. However this is fairly low level,
+    and Phil's ESP32-A2DP library does a great job of managing all the scary details.

     A fixed point number has its range defined by the number of bits encoding the integer part (NI 
-    in the following) and its precision by the number of bits encoding the fractional part (NF). For UFixMath types, the integral part can hold values in [0,2^NI-1], for SFixMath types, the integral part can hold values in [-2^NI,2^NI-1].
+    in the following) and its precision by the number of bits encoding the fractional part (NF). For UFixMath types, the integral part can hold values in [0,2^NI-1], for SFixMath types, the integral part can hold values in [-2^NI,2^NI-1]. The number of bits encoding the fractional can be considered as the precision of the number: given NF, the number of possible values in the  [0,1[ range will 2^NF. Hence, given NF, the resolution will be 1/(2^NF).
+
+    Under the hood, these types will keep track of the maximum possible value they might hold (this is the RANGE template parameter), and, if only *SAFE* operations (see below) are used, will automatically adjust there NI and NF to accomodate the result of a operation. It will also try not to promote there internal type when possible, assuming that you use the complete range of a given type.
+
+    The operations possible with these types can be divided into two categories:
+    - the operations between FixMath types are all safe (aka won't overflow) and are the only one included by default
+    - the operations between a FixMath and a native C type (int, float) are NOT safe and are not included by default. In order to activate them, you need to `#define FIXMATHUNSAFE` before including FixMath.h.
+
 
     Like standard C(++) types, the fixed point numbers defined here are following some rules:
     - any fixed type can be converted to another *as long as the value can be represented in the destination type*. Casting to a bigger type in term of NI and NF is safe, but reducing NI can lead to an overflow if the new type cannot hold the integer value and reducing NF leads to a loss of precision.
+    - Fixed types can be constructed from and converted to standard C types.
     - all operations between fixed point number is safe (it won't overflow) and preserve the precision. In particular:
-    - only addition, subtraction and multiplication are implemented
+    - only addition, subtraction and multiplication are implemented (this is a design choice, see below)
     - any operation between a signed and an unsigned leads to a signed number
     - resulting numbers will be casted to a type big enough to store the expected values. It follows that it is worth starting with types that are as small as possible to hold the initial value.
-    - all operations between a fixed point number and a native type (int, float, uint) are *not* safe. If the resulting value cannot be represented in the fixed point type it will overflow. Only addition, subtraction, multiplication and right/left shift are implemented.
-    - safe right/left shifts, which return the correct value in the correct type are implemented as .sR<shift>() and .sL<shift>() respectively, shift being the shifting amount. These shifts are basically on
+    - all operations between a fixed point number and a native type (int, float, uint) are *not* safe. If the resulting value cannot be represented in the fixed point type it will overflow. Only addition, subtraction, multiplication and right/left shift are implemented. These are only accessible activating the `FIXMATHUNSAFE` set.

It will also try not to promote there internal type when possible, assuming that you use the complete range of a given type.

Subject: [PATCH 133/215] Remove STEREO_HACK

This has been deprecated for several years, now. Also, as this is a config option, projects using it will need to adjust, anyway, so it
does not actually help to keep sketches working.

While in the process, turn AudioOutput and AudioOutput_t into typedefs, rather than #defines to reduce the macro-mess. This required
moving some bits around, however.

Subject: [PATCH 137/215] CONTROL_RATE -> MOZZI_CONTROL_RATE

While the old name continues to work, let's be consistent in the examples.
For the same reason (and to silence some legit compiler warnings; consider what happends when changing after inclusion
of PDResonsant.h, for example!), move it above #include <Mozzi.h>, in all examples.

Change occurences of startMozzi(CONTROL_RATE) to simply startMozzi(), which does the same thing.

-/** This file implements two fixed point number classes. These numbers can have a fractional
-    part but are actually standard integers under the hood which makes calculations with them
-    efficient on platforms which do not have a FPU like most micro-controllers. These numbers can be
-    signed (SFix) or unsigned (UFix).
-
-    A fixed point number has its range defined by the number of bits encoding the integer part (NI 
-    in the following) and its precision by the number of bits encoding the fractional part (NF). For UFix types, the integral part can hold values in [0,2^NI-1], for SFix types, the integral part can hold values in [-2^NI,2^NI-1]. The number of bits encoding the fractional can be considered as the precision of the number: given NF, the number of possible values in the  [0,1[ range will 2^NF. Hence, given NF, the resolution will be 1/(2^NF).
-
-    Under the hood, these types will keep track of the maximum possible value they might hold (this is the RANGE template parameter), and, if only *SAFE* operations (see below) are used, will automatically adjust there NI and NF to accomodate the result of a operation. It will also try not to promote there internal type when possible, assuming that you use the complete range of a given type.
-
-    The operations possible with these types can be divided into two categories:
-    - the operations between FixMath types are all safe (aka won't overflow) and are the only one included by default
-    - the operations between a FixMath and a native C type (int, float) are NOT safe and are not included by default. In order to activate them, you need to `#define MOZZI_FIXMATH_UNSAFE` before including FixMath.h.
-
-
-    Like standard C(++) types, the fixed point numbers defined here are following some rules:
-    - any fixed type can be converted to another *as long as the value can be represented in the destination type*. Casting to a bigger type in term of NI and NF is safe, but reducing NI can lead to an overflow if the new type cannot hold the integer value and reducing NF leads to a loss of precision.
-    - Fixed types can be constructed from and converted to standard C types.
-    - all operations between fixed point number is safe (it won't overflow) and preserve the precision. In particular:
-    - only addition, subtraction and multiplication are implemented (this is a design choice, see below)
-    - any operation between a signed and an unsigned leads to a signed number
-    - resulting numbers will be casted to a type big enough to store the expected values. It follows that it is worth starting with types that are as small as possible to hold the initial value.
-    - all operations between a fixed point number and a native type (int, float, uint) are *not* safe. If the resulting value cannot be represented in the fixed point type it will overflow. Only addition, subtraction, multiplication and right/left shift are implemented. These are only accessible activating the `MOZZI_FIXMATH_UNSAFE` set.
-    - safe right/left shifts, which return the correct value in the correct type are implemented as .sR<shift>() and .sL<shift>() respectively, shift being the shifting amount.
-
-    More specifically on the returned types of the operations between fixed point math types:
-    - Additions:
-      - UFix<NI,NF> + UFix<_NI,_NF> returns UFix<MAX(NI,_NI)+1,MAX(NF,_NF)> at worse
-      - SFix<NI,NF> + SFix<_NI,_NF> returns SFix<MAX(NI,_NI)+1,MAX(NF,_NF)> at worse
-      - UFix<NI,NF> + SFix<_NI,_NF> returns SFix<MAX(NI,_NI)+1,MAX(NF,_NF)> at worse
-      - UFix<NI,NF> + anything_else (signed or not) returns UFix<NI,NF> (only available with `MOZZI_FIXMATH_UNSAFE`)
-      - SFix<NI,NF> + anything_else (signed or not) returns SFix<NI,NF> (only available with `MOZZI_FIXMATH_UNSAFE`)
-    - Subtractions:
-      - UFix<NI,NF> - UFix<_NI,_NF> returns SFix<MAX(NI,_NI),MAX(NF,_NF)> at worse
-      - SFix<NI,NF> - SFix<_NI,_NF> returns SFix<MAX(NI,_NI)+1,MAX(NF,_NF)> at worse
-      - SFix<NI,NF> - UFix<_NI,_NF> returns SFix<MAX(NI,_NI)+1,MAX(NF,_NF)> at worse
-      - UFix<NI,NF> - anything_else (signed or not) returns UFix<NI,NF> (only available with `MOZZI_FIXMATH_UNSAFE`)
-      - SFix<NI,NF> - anything_else (signed or not) returns SFix<NI,NF> (only available with `MOZZI_FIXMATH_UNSAFE`)
-      - (-)SFix<NI,NF> return SFix<NI,NF>
-      - (-)UFix<NI,NF> return SFix<NI,NF>
-    - Multiplications:
-      - UFix<NI,NF> * UFix<_NI,_NF> returns UFix<NI+_NI,NF+_NF> at worse
-      - UFix<NI,NF> * SFix<_NI,_NF> returns SFix<NI+_NI,NF+_NF> at worse
-      - SFix<NI,NF> * SFix<_NI,_NF> returns SFix<NI+_NI,NF+_NF> at worse
-      - UFix<NI,NF> * anything_else (signed or not) returns UFix<NI,NF> (only available with `MOZZI_FIXMATH_UNSAFE`)
-      - SFix<NI,NF> * anything_else (signed or not) returns SFix<NI,NF> (only available with `MOZZI_FIXMATH_UNSAFE`)
-    - Shifts:
-      - UFix<NI,NF> .sR<NS> returns UFix<NI-NS,NF+NS>
-      - UFix<NI,NF> .sL<NS> returns UFix<NI+NS,NF-NS>
-      - same for SFix.
-    - Inverse:
-      - UFix<NI,NF>.invFast() returns the inverse of the number as UFix<NF,NI>
-      - SFix<NI,NF>.invFast() returns the inverse of the number as SFix<NF,NI>
-      - UFix<NI,NF>.invAccurate() returns the inverse of the number as UFix<NF,2*NI+NF>
-      - SFix<NI,NF>.invAccurate() returns the inverse of the number as SFix<NF,2*NI+NF>
-      - UFix<NI,NF>.inv<_NF>() returns the inverse of the number as UFix<NF,_NF>
-      - SFix<NI,NF>.inv<_NF>() returns the inverse of the number as SFix<NF,_NF>
-    - Conversion (should be preferred over casting, when possible):
-      - UFix<NI,NF>.asSFix() returns SFix<NI,NF>
-      - SFix<NI,NF>.asUFix() returns UFix<NI,NF>
-      - UFix<NI,NF>.asFloat() returns the value as a float.
-      - SFix<NI,NF>.asFloat() returns the value as a float.
-      - UFix<NI,NF>.asRaw() returns the internal value.
-      - SFix<NI,NF>.asRaw() returns the internal value.
-      - T.toUFraction() returns UFix<0,NF> with NF the number of bits of T (uint8_t leads to NF=8bits).
-      - T.toSFraction() returns SFix<0,NF> with NF the number of bits of T (int8_t leads to NF=7bits).
-      - T.toUInt() returns UFix<NI,0> with NI the number of bits of T (uint8_t leads to NI=8bits).
-      - T.toSInt() returns SFix<NI,> with NI the number of bits of T (int8_t leads to NI=7bits).   
-    
-    Note on division:
-      The division is not implemented. This is a deliberate choice made for two reasons:
-        - in contrast with all the other fundamental operations, it is not possible to guarantee that precision will be kept (other operations returns *exact* results whenever the operands were also exactly represented. Note that this is actually not the case when using normal floating point numbers. The inverse functions can be used to fake a division, by multiplying by the inverse of a number.
-	- division are usually very slow operations on MCU, hence there usage is discouraged. The ideal way of doing it is to compute the inverse whenever needed and only when needed. In the context of Mozzi for instance, a good way to do it would be to compute needed inverses in updateControl(), and use them in updateAudio().

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice

+That's all there is to it!

-Using Creative Commons Public Licenses
-
-Creative Commons public licenses provide a standard set of terms and
-conditions that creators and other rights holders may use to share
-original works of authorship and other material subject to copyright
-and certain other rights specified in the public license below. The
-following considerations are for informational purposes only, are not
-exhaustive, and do not form part of our licenses.
-
-     Considerations for licensors: Our public licenses are
-     intended for use by those authorized to give the public
-     permission to use material in ways otherwise restricted by
-     copyright and certain other rights. Our licenses are
-     irrevocable. Licensors should read and understand the terms
-     and conditions of the license they choose before applying it.
-     Licensors should also secure all rights necessary before
-     applying our licenses so that the public can reuse the
-     material as expected. Licensors should clearly mark any
-     material not subject to the license. This includes other CC-
-     licensed material, or material used under an exception or
-     limitation to copyright. More considerations for licensors:
-	wiki.creativecommons.org/Considerations_for_licensors
-
-     Considerations for the public: By using one of our public
-     licenses, a licensor grants the public permission to use the
-     licensed material under specified terms and conditions. If
-     the licensor's permission is not necessary for any reason--for
-     example, because of any applicable exception or limitation to
-     copyright--then that use is not regulated by the license. Our
-     licenses grant only permissions under copyright and certain
-     other rights that a licensor has authority to grant. Use of
-     the licensed material may still be restricted for other
-     reasons, including because others have copyright or other
-     rights in the material. A licensor may make special requests,
-     such as asking that all changes be marked or described.
-     Although not required by our licenses, you are encouraged to
-     respect those requests where reasonable. More considerations
-     for the public:

-
-Section 2 -- Scope.
-
-  a. License grant.
-
-       1. Subject to the terms and conditions of this Public License,
-          the Licensor hereby grants You a worldwide, royalty-free,
-          non-sublicensable, non-exclusive, irrevocable license to
-          exercise the Licensed Rights in the Licensed Material to:
-
-            a. reproduce and Share the Licensed Material, in whole or
-               in part, for NonCommercial purposes only; and
-
-            b. produce, reproduce, and Share Adapted Material for
-               NonCommercial purposes only.
-
-       2. Exceptions and Limitations. For the avoidance of doubt, where
-          Exceptions and Limitations apply to Your use, this Public
-          License does not apply, and You do not need to comply with
-          its terms and conditions.
-
-       3. Term. The term of this Public License is specified in Section
-          6(a).
-
-       4. Media and formats; technical modifications allowed. The
-          Licensor authorizes You to exercise the Licensed Rights in
-          all media and formats whether now known or hereafter created,
-          and to make technical modifications necessary to do so. The
-          Licensor waives and/or agrees not to assert any right or
-          authority to forbid You from making technical modifications
-          necessary to exercise the Licensed Rights, including
-          technical modifications necessary to circumvent Effective
-          Technological Measures. For purposes of this Public License,
-          simply making modifications authorized by this Section 2(a)
-          (4) never produces Adapted Material.
-
-       5. Downstream recipients.
-
-            a. Offer from the Licensor -- Licensed Material. Every
-               recipient of the Licensed Material automatically
-               receives an offer from the Licensor to exercise the
-               Licensed Rights under the terms and conditions of this
-               Public License.
-
-            b. Additional offer from the Licensor -- Adapted Material.
-               Every recipient of Adapted Material from You
-               automatically receives an offer from the Licensor to
-               exercise the Licensed Rights in the Adapted Material
-               under the conditions of the Adapter's License You apply.
-
-            c. No downstream restrictions. You may not offer or impose
-               any additional or different terms or conditions on, or
-               apply any Effective Technological Measures to, the
-               Licensed Material if doing so restricts exercise of the
-               Licensed Rights by any recipient of the Licensed
-               Material.
-
-       6. No endorsement. Nothing in this Public License constitutes or
-          may be construed as permission to assert or imply that You
-          are, or that Your use of the Licensed Material is, connected
-          with, or sponsored, endorsed, or granted official status by,
-          the Licensor or others designated to receive attribution as
-          provided in Section 3(a)(1)(A)(i).
-
-  b. Other rights.
-
-       1. Moral rights, such as the right of integrity, are not
-          licensed under this Public License, nor are publicity,
-          privacy, and/or other similar personality rights; however, to
-          the extent possible, the Licensor waives and/or agrees not to
-          assert any such rights held by the Licensor to the limited
-          extent necessary to allow You to exercise the Licensed
-          Rights, but not otherwise.
-
-       2. Patent and trademark rights are not licensed under this
-          Public License.
-
-       3. To the extent possible, the Licensor waives any right to
-          collect royalties from You for the exercise of the Licensed
-          Rights, whether directly or through a collecting society
-          under any voluntary or waivable statutory or compulsory
-          licensing scheme. In all other cases the Licensor expressly
-          reserves any right to collect such royalties, including when
-          the Licensed Material is used other than for NonCommercial
-          purposes.
-
-
-Section 3 -- License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-  a. Attribution.
-
-       1. If You Share the Licensed Material (including in modified
-          form), You must:
-
-            a. retain the following if it is supplied by the Licensor
-               with the Licensed Material:
-
-                 i. identification of the creator(s) of the Licensed
-                    Material and any others designated to receive
-                    attribution, in any reasonable manner requested by
-                    the Licensor (including by pseudonym if
-                    designated);
-
-                ii. a copyright notice;
-
-               iii. a notice that refers to this Public License;
-
-                iv. a notice that refers to the disclaimer of
-                    warranties;
-
-                 v. a URI or hyperlink to the Licensed Material to the
-                    extent reasonably practicable;
-
-            b. indicate if You modified the Licensed Material and
-               retain an indication of any previous modifications; and
-
-            c. indicate the Licensed Material is licensed under this
-               Public License, and include the text of, or the URI or
-               hyperlink to, this Public License.
-
-       2. You may satisfy the conditions in Section 3(a)(1) in any
-          reasonable manner based on the medium, means, and context in
-          which You Share the Licensed Material. For example, it may be
-          reasonable to satisfy the conditions by providing a URI or
-          hyperlink to a resource that includes the required
-          information.
-       3. If requested by the Licensor, You must remove any of the
-          information required by Section 3(a)(1)(A) to the extent
-          reasonably practicable.
-
-  b. ShareAlike.
-
-     In addition to the conditions in Section 3(a), if You Share
-     Adapted Material You produce, the following conditions also apply.
-
-       1. The Adapter's License You apply must be a Creative Commons
-          license with the same License Elements, this version or
-          later, or a BY-NC-SA Compatible License.
-
-       2. You must include the text of, or the URI or hyperlink to, the
-          Adapter's License You apply. You may satisfy this condition
-          in any reasonable manner based on the medium, means, and
-          context in which You Share Adapted Material.
-
-       3. You may not offer or impose any additional or different terms
-          or conditions on, or apply any Effective Technological
-          Measures to, Adapted Material that restrict exercise of the
-          rights granted under the Adapter's License You apply.
-
-
-Section 4 -- Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that
-apply to Your use of the Licensed Material:
-
-  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
-     to extract, reuse, reproduce, and Share all or a substantial
-     portion of the contents of the database for NonCommercial purposes
-     only;
-
-  b. if You include all or a substantial portion of the database
-     contents in a database in which You have Sui Generis Database
-     Rights, then the database in which You have Sui Generis Database
-     Rights (but not its individual contents) is Adapted Material,
-     including for purposes of Section 3(b); and
-
-  c. You must comply with the conditions in Section 3(a) if You Share
-     all or a substantial portion of the contents of the database.
-
-For the avoidance of doubt, this Section 4 supplements and does not
-replace Your obligations under this Public License where the Licensed
-Rights include other Copyright and Similar Rights.
-
-
-Section 5 -- Disclaimer of Warranties and Limitation of Liability.
-
-  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
-     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
-     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
-     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
-     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
-     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
-     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
-     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
-     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
-     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
-
-  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
-     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
-     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
-     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
-     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
-     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
-     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
-     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
-     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
-
-  c. The disclaimer of warranties and limitation of liability provided
-     above shall be interpreted in a manner that, to the extent
-     possible, most closely approximates an absolute disclaimer and
-     waiver of all liability.
-
-
-Section 6 -- Term and Termination.
-
-  a. This Public License applies for the term of the Copyright and
-     Similar Rights licensed here. However, if You fail to comply with
-     this Public License, then Your rights under this Public License
-     terminate automatically.
-
-  b. Where Your right to use the Licensed Material has terminated under
-     Section 6(a), it reinstates:
-
-       1. automatically as of the date the violation is cured, provided
-          it is cured within 30 days of Your discovery of the
-          violation; or
-
-       2. upon express reinstatement by the Licensor.
-
-     For the avoidance of doubt, this Section 6(b) does not affect any
-     right the Licensor may have to seek remedies for Your violations
-     of this Public License.
-
-  c. For the avoidance of doubt, the Licensor may also offer the
-     Licensed Material under separate terms or conditions or stop
-     distributing the Licensed Material at any time; however, doing so
-     will not terminate this Public License.
-
-  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
-     License.
-
-
-Section 7 -- Other Terms and Conditions.
-
-  a. The Licensor shall not be bound by any additional or different
-     terms or conditions communicated by You unless expressly agreed.
-
-  b. Any arrangements, understandings, or agreements regarding the
-     Licensed Material not stated herein are separate from and
-     independent of the terms and conditions of this Public License.
-
-
-Section 8 -- Interpretation.
-
-  a. For the avoidance of doubt, this Public License does not, and
-     shall not be interpreted to, reduce, limit, restrict, or impose
-     conditions on any use of the Licensed Material that could lawfully
-     be made without permission under this Public License.
-
-  b. To the extent possible, if any provision of this Public License is
-     deemed unenforceable, it shall be automatically reformed to the
-     minimum extent necessary to make it enforceable. If the provision
-     cannot be reformed, it shall be severed from this Public License
-     without affecting the enforceability of the remaining terms and
-     conditions.
-
-  c. No term or condition of this Public License will be waived and no
-     failure to comply consented to unless expressly agreed to by the
-     Licensor.
-
-  d. Nothing in this Public License constitutes or may be interpreted

 ## Use and Remix
-Mozzi is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, which is detailed in LICENSE.txt
+Mozzi is licensed under a the LGPL version 2.1 or (at your option) any later version of the license.
 
 Disclaimer: This is a human-readable summary of (and not a substitute for) the license.
+- You may copy, distribute and modify the Mozzi library itself provided that you state modifications and license them under LGPL-2.1.
 
-You are free to:
- - Share — copy and redistribute the material in any medium or format
- - Adapt — remix, transform, and build upon the material
+- You may distribute *your own* source code which merely *uses* the Mozzi-API under any licence that you wish.
 
-The licensor cannot revoke these freedoms as long as you follow the license terms.
-Under the following terms:
- - Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
- - NonCommercial — You may not use the material for commercial purposes.
- - No additional restrictions — You may not apply legal terms or technological measures that legally restrict others from doing anything the license permits.
+- Regarding distribution of *binaries* (also inside a hardware project) that include Mozzi, the Arduino FAQ sums up the situation as follows:
+  "Using the Arduino core and libraries for the firmware of a commercial product does not require you to release the source code for the firmware. The LGPL does, however, require you to make available object files that allow for the relinking of the firmware against updated versions of the Arduino core and libraries. Any modifications to the core and libraries must be released under the LGPL."
+
+- Note that using third-party libraries/code - including as shown in some of the Mozzi examples - may introduce additional restrictions.

+@note Analog reads have different hardware resolution on different platforms. E.g. an analog read

+      it will return 0-4095 (12 bits). For portable code, it is thus necessary to specify the desired
+      resolution of reads. This can be done by setting MOZZI_ANALOG_READ_RESOLUTION to the resolution
+      in bits, near the top of your sketch. All reads will then be adjusted to that range, automatically
+      (using a simple bit-shift). Alternatively, the templated version of mozziAanalogRead() allows
+      to specifiy the target resolution per read.
+      If MOZZI_ANALOG_READ_RESOLUTION is not defined, this (non-templated) function returns a value

+
+
+<h3><a id="mozzi_audio_output_architecture"></a>Basic architecture of audio generation, buffering, and output in Mozzi</h3><div class="textblock">Mozzi provides support for audio ouput on a range of different boards and CPUs.This page is about the following related topics:<ul>
+<li>adding a custom output method (importantly using external DACs) to your sketch</li>
+<li>writing sketches that will work on different platforms / with different output methods</li>
+<li>extending Mozzi for a new architecture</li>
+</ul>
+For all of these topics, it is helpful to have a basic understanding of the basic output steps in Mozzi:<ol type="1">
+<li>Inside the loop() function in your sketch you call <a class="el" href="group__core.html#ga2fca37b988ab369e2f3c3108c683e59d" title="This is required in Arduino&#39;s loop(). ">audioHook()</a>. 1a. If the audio output buffer is currently filled, this does nothing. 1b. Otherwise, this calls <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code. ">updateAudio()</a>. The generated sample is then added to the audio output buffer. (Also, <a class="el" href="group__core.html#ga59d187b915b2e366c88489e52801951a" title="This is where you put your control code. ">updateControl()</a> will be called at an appropriate rate, and a few other details that are not important for this discussion.)</li>
+<li>A platform-specific timer is triggered at audio rate (usually), takes a sample from the output buffer and sends it to audioOutput().</li>
+<li>The audioOutput() function - usually predefined inside Mozzi - takes care of sending the sample to the hardware.</li>
+</ol>
+These output steps are not always followed, however. Firstly, when using <a class="el" href="group__audio__output.html">External audio output</a> output, the audioOutput() funtion is supplied by the user sketch, instead of Mozzi. <a class="el" href="group__audio__output.html">External audio output</a> output.Some ports will also want to bypass the Mozzi audio output buffer. For instance, an internal DAC may be addressable via an efficient DMA-connected buffer, already, and also have a built-in rate control. In this case, ports will internally set the define BYPASS_MOZZI_OUTPUT_BUFFER to true. Such a port will have to provide a custom definition of canBufferAudioOutput(), returning true, whenever a new sample of output can be accepted. No timer at audio-rate is set up in this case.Finally, the <a class="el" href="group__audio__output.html">External audio output</a> output mode (<a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a> MOZZI_OUTPUT_EXTERNAL_CUSTOM) is essentially a combination of the two. Here, the user sketch needs to provide both audioOutput() and canBufferAudioOutput(). The latter is again called from <a class="el" href="group__core.html#ga2fca37b988ab369e2f3c3108c683e59d" title="This is required in Arduino&#39;s loop(). ">audioHook()</a>, and whenever it returns true, a new sample is generated and passed to audioOutput().<h1><a class="anchor" id="audio_shifting"></a>
+Platform specific audio resolution</h1>
+<p>Different output methods often support a different resolution of output samples. To provide best performance on slow boards, Mozzi expects your <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code. ">updateAudio()</a> function to return samples in exactly the width that is needed at the output stage. Thus, defining this naively, an <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code. ">updateAudio()</a> function designed for 8 bit output will produce very low volume output on a 16 bit DAC, while the other way around overflows will result in way too loud and heavily distored output. Fortunately, all that is needed to write portable sketches is to specify how many bits your <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code. ">updateAudio()</a> function provides. The (inline) functions in the AudioOutput namespace do just that. Using them makes sure your audio output is shifted if, and as much as needed on all platforms.</p>

">MonoOutput::fromNBit()</a>, <a class="el" href="struct_stereo_output.html#aba322189d188eb977cc74a8c6ae909c1" title="See MonoOutput::fromNBit(), stereo variant.

+<h3><a id="external_audio"></a>External audio output</h3><div class="textblock"><em>Only for <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a> set to MOZZI_OUTPUT_EXTERNAL_TIMED or MOZZI_OUTPUT_EXTERNAL_CUSTOM</em>. Most (all?) platforms support output using an "external" function. When using this option, you will need to provide a suitable definition for audioOutput() in your own sketch, yourself. Some understanding of the general Mozzi audio output architecture may be recommendable, when using this mode: See AudioOutput .In the more simple case (MOZZI_OUTPUT_EXTERNAL_TIMED), Mozzi will still take care of buffering the samples, and calling this function at audio rate (hence "timed"). This generally involves use of a timer, which should be detailed in the <a class="el" href="group__hardware.html">Hardware</a> details for your platform.Should you desire even more control - perhaps because your board, or your external DAC already comes with a rate controlled DMA buffer - using MOZZI_OUTPUT_EXTERNAL_CUSTOM also bypasses Mozzis sample buffer. In addition to audioOutput(), you will then need to provide a definition for canBufferAudioOutput(), which will control the rate at which samples are produced. In essence, whenever canBufferAudioOutput() returns true, Mozzi will call <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code. ">updateAudio()</a>, and pass the produced sample to audioOutput(), unbuffered. It is entirely your job to make sure that this actually happens at MOZZI_AUDIO_RATE, and / or an appropriate buffer gets used.One additional configuration setting is MOZZI_AUDIO_BITS, which defaults to 16 bits for this mode, but might be set higher, if your hardware supports it.<dl class="section see"><dt>See also</dt><dd><a class="el" href="group__config.html">Mozzi Configuration options</a> </dd></dl>

+Configuring Mozzi</h1>
+<p>Mozzi configuration options include details such as audio rate, number of audio channels (mono or stereo), output generation method and many others, where details on the available options differ between the different platforms (see <a class="el" href="group__hardware.html">Hardware</a>), and may include additional options beyond those listed, here.</p>
+<dl class="section note"><dt>Note</dt><dd>It is generally safe to leave the Mozzi Configuration unchanged, and that's very much recommended <em>until</em> you have a very specific need to customize something. Contrary to past versions of Mozzi, all configuration options have a (usually sensible) default value, so you do not have to configure <em>anything</em>, unless you actually want to change something.</dd></dl>
+<p>Configuring Mozzi is mostly done using various preprocessor definitions. This approach is used to move as much of the processing involved to compile time, in order to save Flash, RAM, and CPU use at runtime. This section lists various global options, but in addition, most ports allow additional hardware dependent configuration options. See <a class="el" href="group__hardware.html">Hardware</a>.</p>
+<p>Several configuration examples are provided in the "config" folder of the Mozzi sources. You may want to look at these, first. The general approach is as follows:</p>

+<p>Whether to compile in support for non-blocking analog reads. </p>
+<p>This is enabled by default on platforms that support it, but may be disabled, explicitly, to save resources, or in order to implement custom read schemes (e.g. with IO multiplexing).</p>
+<p>For simplicity, <a class="el" href="group__analog.html#gae9536bf35f6ea46a6938d5eb52b947c3" title="Reads the analog input of a chosen channel, without blocking other operations from running...">mozziAnalogRead()</a> is always defined, but when MOZZI_ANALOG_READ s are disabled or unsupported, it simply relays to Arduino's regular analogRead(). It is thus quite recommended <em>not</em> to depend on <a class="el" href="group__analog.html#gae9536bf35f6ea46a6938d5eb52b947c3" title="Reads the analog input of a chosen channel, without blocking other operations from running...">mozziAnalogRead()</a> when disabling this.</p>
+<p>As a rough estimate (your numbers may differ a bit, depending on compiler version, etc.), on an ATMEGA328P (aka Arduino Uno), disabling analog reads saves 33 bytes of RAM and 340 bytes of FLASH. The performance savings are theorized to be neglegible, however.</p>
+<p>Currently allowed values are:</p><ul>
+<li>MOZZI_ANALOG_READ_NONE Disabled</li>

When customizing this, it is highly recommended to start experimenting with a simple and known-to-work sketch (such as a basic sinewave) to verify that your hardware setup is correct. Similarly, if you observe problems running your "real" sketch, it is often a good idea ot test your sketch with the default audio mode, too (by leaving this option, and preferrably all others, unset).</dd></dl>
+<p>Refer to the <a class="el" href="group__hardware.html">Hardware</a> specific documentation for which modes are supported on your hardware, and further details!</p>
+<p>Supported values:</p><ul>
+<li>MOZZI_OUTPUT_PWM Output using pulse width modulation (PWM) on a GPIO pin. This is the default on most platforms. On the Arduino Uno (more generally ATMEGA328P), this allows for a sample resolution of 488 (almost 9 bits) on pin 9. Usable pins and resolution will be different on other boards.</li>
+<li>MOZZI_OUTPUT_2PIN_PWM Output using pulse width modulation on two GPIO pins, where one pin represents the lower bits, and the other the higer bits of the sample. On the Aduino Uno, this allows for 14 bits of resolution on pins 9 (low) and 10 (high). For further information (wiring etc.) see hardware_avr_2pin.</li>
+<li>MOZZI_OUTPUT_EXTERNAL_TIMED Output is not controlled by Mozzi itself, but left to the user sketch. This setting allows to completely customize the audio output, e.g. for connecting to external DACs. For more detail, see <a class="el" href="group__audio__output.html">External audio output</a></li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM As above, but additionally bypassing Mozzi's sample buffer. For more detail, see <a class="el" href="group__audio__output.html">External audio output</a></li>
+<li>MOZZI_OUTPUT_PDM_VIA_I2S Output pulse density modulated (PDM) samples via a (hardware) I2S interface (without a DAC connected to it).</li>
+<li>MOZZI_OUTPUT_PDM_VIA_SERIAL Output pulse density modulated (PDM) samples via a hardware serial interface.</li>
+<li>MOZZI_OUTPUT_I2S_DAC Output samples to a PT8211 (or compatible) DAC connected to a hardware I2S interface.</li>
+<li>MOZZI_OUTPUT_INTERNAL_DAC Output to the interal DAC on boards that support one.</li>

+<p>The default rate on the classis Arduino Uno is 16384 Hz, but can be increased to 32768 Hz, subject to the caveats, detailed below. For most other platforms 32678 Hz is the default, but even higher rates may be supported. Increasing the rate allows for better frequency response, but generally all affects achievable sample bitdepth (especially from PWM output). Also, of course, doubling the sample rate also halves the amount of time available to calculate the each sample, so it may only be useful for relatively simple sketches. The increased frequency response can also make unwanted artefacts of low resolution synthesis calculations more apparent, so it's not always a bonus.</p>
+<p>It is highly recommended to keep the audio rate a power of two (16384, 32678, 64536, etc.), as some internal calculations can be highly be optimised for speed, this way.</p>

+<p>On some platforms, the rate at which PWM signals are repeated may be higher than that at with audio signals are produced (i.e. MOZZI_AUDIO_RATE). E.g. for MOZZI_OUTPUT_PWM on the classic Arduino, the pwm defaults to 32768 while the audio rate defaults to 16384. The reasoning behind this is that 16384 Hz audio rate turned out to be te most useful compromise - in most casses - between output quality, and available computing power. However, output at that rate produced high-frequency whine, audible to some people, which could be mitigated by the higher PWM rate.</p>
+<p>In other words, increasing this improves the signal quality at less cost than doubling the audio rate itself. However, increasing this too far will limit the dynamic resolution of the samples that can be written to the output pin(s): 2 ^ (output bits) * MOZZI_PWM_RATE cannot be higher than the CPU frequency! </p>

-<p>AUDIO_RATE can be #defined as 16384 or 32768 Hertz in <a class="el" href="mozzi__config_8h_source.html">Mozzi/mozzi_config.h</a>.</p>
-<p>Mozzi's original audio mode, now called STANDARD, uses 16384 Hz, chosen as a compromise between the sample rate (interrupt rate) and sample bitdepth (pwm width), which are interdependent due to the way pulse wave modulation is used to generate the sound output. An AUDIO_RATE of 32768 Hz works in STANDARD_PLUS and HIFI modes. Of course, doubling the sample rate halves the amount of time available to calculate the each sample, so it may only be useful for relatively simple sketches. The increased frequency response can also make unwanted artefacts of low resolution synthesis calculations more apparent, so it's not always a bonus.</p>
-<p>Another factor which is important for Mozzi's operation is that with AUDIO_RATE being a power of two, some internal calculations can be highly optimised for speed.</p>
-<p>In STANDARD and STANDARD_PLUS modes, the sample resolution is 488, which provides some headroom above the 8 bit table resolution currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.</p>
-<p>HIFI audio mode enables much higher quality output by combining signals from pins 9 and 10. For HIFI mode, edit <a class="el" href="mozzi__config_8h_source.html">Mozzi/mozzi_config.h</a> to contain #define AUDIO_MODE HIFI, and comment out #define AUDIO_MODE STANDARD and #define AUDIO_MODE STANDARD_PLUS.</p>

-<p>Used to set AUDIO_MODE to STANDARD, STANDARD_PLUS, or HIFI. </p>
-<h2>STANDARD / STANDARD_PLUS </h2>
-<p>Use #define AUDIO_MODE STANDARD_PLUS in Mozzi/config.h to select this output configuration, which is nearly 9 bit sound (-244 to 243) at 16384 Hz sample rate (AUDIO_RATE) and 32768 Hz PWM rate. It uses Timer 1 for PWM and the sample updating routine (as an interrupt).</p>
-<p>STANDARD is obsolete now, replaced by STANDARD_PLUS which is the default audio mode. STANDARD mode uses 16384 Hz PWM rate with an output interrupt at the same frequency. Some people can hear the PWM carrier frequency as an annoying whine.</p>
-<p>STANDARD_PLUS mode uses 32768 Hz PWM rate, so the PWM carrier is out of hearing range. In this mode every alternate interrupt is used for the sample update (unless you /#define AUDIO_RATE 32768 in <a class="el" href="mozzi__config_8h_source.html">mozzi_config.h</a>), which makes it slightly less efficient than STANDARD, but almost always better.</p>
-<p>Advantages: Only uses one timer for audio, and one output pin. Disadvantages: low dynamic range.</p>
-<p>Below is a list of the Digital Pins used by Mozzi for STANDARD and STANDARD_PLUS audio out on different boards. Those which have been tested and reported to work have an x. Feedback about others is welcome.</p>

-<p>On Teensy 3.* STANDARD and STANDARD_PLUS are the same, providing 16384Hz sample rate and 12 bit resolution on pin A14/ADC. The Teensy 3.* DAC output does not rely on PWM.</p>
-<p>Used to set AUDIO_MODE to HIFI.</p>
-<h2>HIFI for AVR and STM32 (not for Teensy 3.*) </h2>
-<p>Use #define AUDIO_MODE HIFI in Mozzi/config.h to set the audio mode to HIFI for output 14 bit sound at 16384 Hz sample rate and 125kHz PWM rate. The high PWM rate of HIFI mode places the carrier frequency beyond audible range.</p>
-<p>Also, 14 bits of dynamic range in HIFI mode provides more definition than the nearly 9 bits in STANDARD_PLUS mode. HIFI mode takes about the same amount of processing time as STANDARD_PLUS mode, and should sound clearer and brighter. However, it requires an extra timer to be used on the Arduino, which could increase the chances of conflicts with other libraries or processes if they rely on Timer 2.</p>
-<p>Timer 1 is used to provide the PWM output at 125kHz. Timer 2 generates an interrupt at AUDIO_RATE 16384 Hz, which sets the Timer1 PWM levels. HIFI mode uses 2 output pins, and sums their outputs with resistors, so is slightly less convenient for rapid prototyping where you could listen to STANDARD_PLUS mode by connecting the single output pin directly to a speaker or audio input (though a resistor of about 100 ohms is recommended).</p>
-<p>The resistors needed for HIFI output are 3.9k and 499k, with 0.5% or better tolerance. If you can only get 1% resistors, use a multimeter to find the most accurate. Use two 1M resistors in parallel if you can't find 499k.</p>
-<p>On 328 based Arduino boards, output is on Timer1, with the high byte on Pin 9 and low byte on Pin 10. Add the signals through a 3.9k resistor on high byte pin (9) and 499k resistor on low byte pin (10). Also, a 4.7nF capacitor is recommended between the summing junction of the resistors and ground.</p>
-<p>This dual PWM technique is discussed on <a href="http://www.openmusiclabs.com/learning/digital/pwm-dac/dual-pwm-circuits/">http://www.openmusiclabs.com/learning/digital/pwm-dac/dual-pwm-circuits/</a> Also, there are higher quality output circuits are on the site.</p>
-<p>Advantages: should be higher quality sound than STANDARD_PLUS mode. Doesn't need a notch filter on the audio signal (like STANDARD which is now obsolete) because the carrier frequency is out of hearing range.</p>
-<p>Disadvantages: requires 2 pins, 2 resistors and a capacitor, so it's not so quick to set up compared to a rough, direct single-pin output in STANDARD_PLUS mode.</p>
-<p>Pins and where to put the resistors on various boards for HIFI mode. Boards tested in HIFI mode have an x, though most of these have been tested in STANDARD_PLUS mode and there's no reason for them not to work in HIFI (unless the pin number is wrong or something). Any reports are welcome. <br />

+<h3><a id="hardware_avr"></a>Mozzi on classic Arduino, Teensy 2.x, Arduino Mega, and other 8 bit &quot;AVR&quot;/ATMEGA architecture boards</h3><div class="textblock"><h1><a class="anchor" id="avr_status"></a>
+Port status and notes</h1>
+<p>This is the original "port" of Mozzi, and thus very elaborate. The main challenges on this platform, compared to other MCUs, are limitations in flash, RAM, and CPU power.</p>
+<h1><a class="anchor" id="avr_output"></a>
+Output modes</h1>
+<p>The following audio modes (see <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a>) are currently supported on this hardware:</p><ul>
+<li>MOZZI_OUTPUT_PWM</li>
+<li>MOZZI_OUTPUT_2PIN_PWM</li>
+<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
+</ul>
+<p>In all modes, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose. This means, among other things, that pins 9 and 10 cannot be used for analogWrite(), while pins 3 and 11 should still be available <em>except</em> in MOZZI_OUTPUT_2PIN_PWM mode (as Timer2 is also claimed, then; for definite info on which pin is connected to which timer, check a suitable reference, as your board may differ). See <em>Mozzi&gt;examples&gt;11.Communication&gt;Sinewave_PWM_pins_HIFI</em>. for an example of emulating analogWrite() on any digital pin, without the need for a hardware timer.</p>
+<h1><a class="anchor" id="avr_pwm"></a>
+MOZZI_OUTPUT_PWM</h1>
+<p>For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured within this tight limit. In particular, the default setup on the Arduino UNO is:</p><ul>
+<li>Mono: Pin 9 -&gt; configurable using MOZZI_AUDIO_PIN_1</li>
+<li>Stereo: Pin 9 (left) and Pin 10 (right) -&gt; configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2 For pinouts on other boards, refer to config/known_16bit_timers.</li>
+</ul>
+<p>Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.</p>
+<p>The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.</p>
+<h1><a class="anchor" id="avr_2pin_pwm"></a>
+MOZZI_OUTPUT_2PIN_PWM</h1>
+<p>In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for much better dynamic range, providing much more definition than can be achieved using <a class="el" href="group__hardware.html#avr_pwm">MOZZI_OUTPUT_PWM</a> , while using only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see <a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>), which is well beyond the audible range.</p>
+<p>On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient for rapid prototyping. For circuit details, see <a href="https://sensorium.github.io/Mozzi/learn/output/">https://sensorium.github.io/Mozzi/learn/output/</a> .</p>
+<p>On the classic Arduino Uno, the default pinout in this mode is:</p><ul>
+<li>Pin 9 (high bits) and Pin 10 (low bits) -&gt; configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW</li>
+</ul>
+<p>Here is table of the default pins on some other boards. Rows with an x on it have actually been tested (and importantly, the outcome recoreded; input welcome on further boards.)</p>

+ For pinouts on other AVR boards, config/known_16bit_timers might contain some hints.</p>
+<p>Rate of the PWM output can be controlled separately from <a class="el" href="group__config.html#gabc7b46bc3dbe1078f411287572226eff">MOZZI_AUDIO_RATE</a>, and is much higher (125kHz), by default: <a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>.</p>
+<p>The default sample resolution is 7 bits per pin, for a total of 14 bits. This can be configured within hardware limits (<a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>) using <a class="el" href="group__config.html#ga9bfd84013cbc04ddb51b31f583178720">MOZZI_AUDIO_BITS_PER_CHANNEL</a>, but beware that increasing this will require even more accuracy in our output resistors (see the linked documentation, above).</p>

+<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
+<li>MOZZI_OUTPUT_PDM_VIA_I2S</li>
+<li>MOZZI_OUTPUT_I2S_DAC</li>
+<li>MOZZI_OUTPUT_INTERNAL_DAC</li>
+</ul>
+<p>The default mode is <a class="el" href="group__hardware.html#esp32_internal_dac">MOZZI_OUTPUT_INTERNAL_DAC</a> .</p>
+<h1><a class="anchor" id="esp32_internal_dac"></a>
+MOZZI_OUTPUT_INTERNAL_DAC</h1>
+<p>The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used. In a mono configuration, both pins output the same sample.</p>
+<p>TODO: We could really use this to hack in a 2 PIN mode!</p>
+<dl class="section note"><dt>Note</dt><dd>The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that. Check a detailed pinout diagram, if in any doubt.</dd></dl>
+<p>Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)</span></div></div><!-- fragment --><h1><a class="anchor" id="esp32_i2s_dac"></a>
+MOZZI_OUTPUT_I2S_DAC</h1>
+<p>This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins of one I2S interface. Presumably, any pins qualify, and you can configure this using: </p><div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_I2S_PIN_BCK  ... // (default: 26)</span></div><div class="line"><span class="preprocessor">#define MOZZI_I2S_PIN_WS   ... // (default: 15)</span></div><div class="line"><span class="preprocessor">#define MOZZI_I2S_PIN_DATA ... // (default: 33)</span></div><div class="line"><span class="preprocessor">#define MOZZI_I2S_PORT     ... // (default: I2S_NUM_0)</span></div></div><!-- fragment --><p>See the note above (esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!</p>
+<p>As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h". This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!</p>
+<h1><a class="anchor" id="esp32_pdm_via_i2s"></a>
+MOZZI_OUTPUT_PDM_VIA_I2S</h1>
+<p>This mode uses the same setup as <a class="el" href="group__hardware.html#esp32_i2s_dac">MOZZI_OUTPUT_I2S_DAC</a>, but rather than using an external DAC, the communication signal itself is modulated in PDM (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.</p>
+<p>Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.</p>

Mozzi tries to set GPIO2 and GPIO15 to input mode, and <em>at the time of this writing</em>, this allows I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Ground).

+<li>The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:<ul>
+<li>Some boards use dedicated cores (e.g. Arduino Giga / Portenta <a class="el" href="group__hardware.html">Mozzi on MBED-based boards (Arduino Giga / Portenta).</a>) etc. For those, see the relevant sections (if we support them).</li>
+<li>There is a series of libmaple-based cores, including <a href="https://github.com/rogerclarkmelbourne/Arduino_STM32">Roger Clark's libmaple-based core</a>. These are highly optimized, and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation via the Arduino Board Manager, and they do not currently seem actively maintained. For using these with Mozzi, see <a class="el" href="group__hardware.html">Mozzi on STM32duino-based boards.</a></li>
+<li>A generic Arduino core for STM32 is the <a href="https://github.com/stm32duino/Arduino_Core_STM32">STM32duino core</a>. It supports a huge set of boards, and seems to have offical backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what the libmaple cores above were known by (don't blame Mozzi for this mess!).

+<p>The following audio modes (see <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a>) are currently supported on this hardware:</p><ul>
+<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
+<li>MOZZI_OUTPUT_INTERNAL_DAC</li>

+<h1><a class="anchor" id="teensy3_internal_dac"></a>
+MOZZI_OUTPUT_INTERNAL_DAC</h1>
+<p>Output is to the inbuilt DAC. Output resolution is 12 bits. Mono, only. The DAC output pin differs from board to boards. In most cases the appropriate pin will be set outmatically. If needed, you can specify the DAC pin, explicitly:</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_AUDIO_PIN_1       ...  // Default: A14, A12, or A21, depending on board</span></div></div><!-- fragment --><h1><a class="anchor" id="teensy3_external"></a>

+<p>This port requires the following two libraries (which should be part of a default installtion, however):</p><ul>
+<li><a href="https://github.com/loglow/IntervalTimer">Timer library</a> for Teensy 4.* by Daniel Gilbert</li>
+<li><a href="http://github.com/pedvide/ADC">ADC library</a> by Pedro Villanueva</li>
+</ul>
+<p>Contrary to the Teensy 3, the Teensy 4 do not have any DAC. The output is done on pin A8 (PWM) by default (see below). twi_nonblock is not ported.</p>

+<dl class="section note"><dt>Note</dt><dd>Intialization of the random seed is done differently on different MCUs, but is nowhere near perfect for most (and for some it is not even implemented at all). Many implementations (e.g. on AVR, STM32) simply rely on reading a (hopefully noisy) internal temperature sensor. You will often get better results by calling analogRead() - <em>not</em> mozziAnalogRead(0), in this case! - on one or two floating (non-connected) analog pins. </dd></dl>

+<div class="textblock"><p>README! This file is meant to be used as a template when adding support for a new platform. </p>
+<p>Please read these instructions, first.</p>
+<p>Files involved:</p><ol type="1">
+<li>Modify <a class="el" href="hardware__defines_8h_source.html">hardware_defines.h</a>, adding a macro to detect your target platform</li>
+<li>Modify MozziGuts.cpp to include MozziGuts_impl_YOURPLATFORM.hpp</li>
+<li>Modify <a class="el" href="config__checks__generic_8h_source.html">internal/config_checks_generic.h</a> to include internal/config_checks_YOURPLATFORM.h</li>
+<li>Copy this file to MozziGuts_impl_YOURPLATFORM.hpp and adjust as necessary, same for <a class="el" href="config__checks__template_8h_source.html">internal/config_checks_template.h</a> (If your platform is very similar to an existing port, it may instead be better to modify the existing MozziGuts_impl_XYZ.hpp/config_checks_XYZ.h, instead of steps 2-3.). Some platforms may need small modifications to other files as well, e.g. <a class="el" href="mozzi__pgmspace_8h_source.html">mozzi_pgmspace.h</a></li>
+</ol>
+<p>How to implement MozziGuts_impl_YOURPLATFORM.hpp:</p><ul>
+<li>Follow the NOTEs provided in this file</li>
+<li>Read the doc at the top of <a class="el" href="_audio_output_8h_source.html">AudioOutput.h</a> for a better understanding of the basic audio output framework</li>
+<li>Take a peek at existing implementations for other hardware (e.g. TEENSY3/4 is rather complete while also simple at the time of this writing)</li>
+<li>Wait for more documentation to arrive</li>
+<li>Ask when in doubt</li>
+<li>Don't forget to provide a PR when done (it does not have to be perfect; e.g. many ports skip analog input, initially) </li>

">StereoOutput</a>, making it easy to e.g. implement support for an external DAC in both mono and stereo. d) Finally, an automatic conversion operator to int aka AudioOutput_t provides backward compatibility with old Mozzi sketches. Internally, the compiler will actually do away with this whole struct, leaving just the same basic fast integer operations as in older Mozzi sketches. However, now, you don't have to rewrite those for different configurations. </p>

-<div class="textblock"><p>This struct encapsulates one frame of mono audio output. </p>
-<p>Internally, it really just boils down to a single int value, but the struct provides useful API an top of that, for the following:</p>
-<p>a) To construct an output frame, you should use one of the <a class="el" href="struct_mono_output.html#a7478d3111845040f553a965e7e54a539" title="Construct an audio frame from a zero-centered value known to be in the 8 bit range. ">from8Bit()</a>, <a class="el" href="struct_mono_output.html#a02f9adf531ab61ce96ed80a8319bdeea" title="Construct an audio frame a zero-centered value known to be in the N bit range. ">fromNBit()</a>, etc. functions. Given a raw input value, at a known resolution (number of bits), this scales the output efficiently to whatever is needed on the target platform. Using this, your <a class="el" href="group__core.html#ga41f0db3f560ff1fdec78f9c60822466e" title="This is where you put your audio code. ">updateAudio()</a> function will be portable across different CPU and different output methods, including external DACs. b) The struct provides some convenience API on top of this. Right now, this is the function <a class="el" href="struct_mono_output.html#a0e641cbab9732214c696cd1071e45de5" title="Clip frame to supported range. ">clip()</a>, replacing the more verbose, and non-portable constrain(x, -244, 243) found in some old sketches. c) The struct provides accessors l() and r() that are source-compatible with <a class="el" href="struct_stereo_output.html" title="This struct encapsulates one frame of mono audio output. ">StereoOutput</a>, making it easy to e.g. implement support for an external DAC in both mono and stereo. d) Finally, an automatic conversion operator to int aka AudioOutput_t provides backward compatibility with old Mozzi sketches. Internally, the compiler will actually do away with this wholw struct, leaving just the same basic fast integer operations as in older Mozzi sketches. However, now, you don't have to rewrite those for different configurations. </p>

 <p>Appropriate left- or right-shifting will be performed, based on the number of output bits available. While this function takes care of the shifting, beware of potential overflow issues, if your intermediary results exceed the 16 bit range. Use proper casts to int32_t or larger in that case (and the compiler will automatically pick the 32 bit overload in this case) </p>

+<div class="line">    not above. This is the principal usage of MetaOscil.</div>
+<div class="line"> </div>
+<div class="line">    MetaOscil can be used (after construction) as a proper Oscil but really is a bunch of oscillators with only one playing.</div>
+<div class="line">    It will switch between different oscils seemlessly depending on the asked frequency. This allows to switch between oscillators with less </div>
+<div class="line">    and less harmonics as the pitch goes up, in order to avoid aliases, which is demonstrated by this example.</div>
+<div class="line"> </div>
+<div class="line">    The bandlimited tables are nammed according to the max frequency they can play without bringing aliases at a given frequency. For example:</div>
+<div class="line">    square_max_90_at_16384_512_int8.h ensures that no aliases will be present up to 90Hz at 16384Hz sampling rate (the default for Arduino).</div>
+<div class="line">    If your sampling rate is higher (say 32768 which is the default for most 32bits platforms) this table will be able to play up to </div>
+<div class="line">    180=90*2Hz without aliases, as the Nyquist frequency is two times higher.</div>

 <dl class="section note"><dt>Note</dt><dd>Intialization of the random seed is done differently on different MCUs, but is nowhere near perfect for most (and for some it is not even implemented at all). Many implementations (e.g. on AVR, STM32) simply rely on reading a (hopefully noisy) internal temperature sensor. You will often get better results by calling analogRead() - <em>not</em> mozziAnalogRead(0), in this case! - on one or two floating (non-connected) analog pins. </dd></dl>

 <p>Alternatively you can export a sound from Audacity, which seems to have less noticeable or no dithering, using Project Rate 16384 Hz and these output options: Other uncompressed files, Header: WAV(Microsoft), Encoding: Unsigned 8 bit PCM</p>
 <p>The header file contains two lengthy arrays: One is "SOUNDDATA" which must fit into Flash RAM (available in total: 32k for ATMega328) The other is "HUFFMAN" which must also fit into Flash RAM </p>

E.g. an analog read on an Arduino Uno R3 will return a value in the range 0-1023 (10 bits), on a Raspberry Pi Pico it will return 0-4095 (12 bits). For portable code, it is thus necessary to specify the desired resolution of reads. This can be done by setting MOZZI_ANALOG_READ_RESOLUTION to the resolution in bits, near the top of your sketch. All reads will then be adjusted to that range, automatically (using a simple bit-shift). Alternatively, the templated version of mozziAanalogRead() allows to specifiy the target resolution per read. If MOZZI_ANALOG_READ_RESOLUTION is not defined, this (non-templated) function returns a value in the default hardware resolution, with a warning.</dd></dl>

To provide best performance on slow boards, Mozzi expects your <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code.">updateAudio()</a> function to return samples in exactly the width that is needed at the output stage. Thus, defining this naively, an <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code.">updateAudio()</a> function designed for 8 bit output will produce very low volume output on a 16 bit DAC, while the other way around overflows will result in way too loud and heavily distored output. Fortunately, all that is needed to write portable sketches is to specify how many bits your <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code.">updateAudio()</a> function provides. The (inline) functions in the AudioOutput namespace do just that. Using them makes sure your audio output is shifted if, and as much as needed on all platforms.</p>

Most (all?) platforms support output using an "external" function. When using this option, you will need to provide a suitable definition for audioOutput() in your own sketch, yourself. Some understanding of the general Mozzi audio output architecture may be recommendable, when using this mode: See AudioOutput .In the more simple case (MOZZI_OUTPUT_EXTERNAL_TIMED), Mozzi will still take care of buffering the samples, and calling this function at audio rate (hence "timed"). This generally involves use of a timer, which should be detailed in the <a class="el" href="group__hardware.html">Hardware</a> details for your platform.Should you desire even more control - perhaps because your board, or your external DAC already comes with a rate controlled DMA buffer - using MOZZI_OUTPUT_EXTERNAL_CUSTOM also bypasses Mozzis sample buffer. In addition to audioOutput(), you will then need to provide a definition for canBufferAudioOutput(), which will control the rate at which samples are produced. In essence, whenever canBufferAudioOutput() returns true, Mozzi will call <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code.

 MOZZI_OUTPUT_PWM</h1>
 <p>Standard pulse width modulated output to one (mono) or two (stereo, see <a class="el" href="group__config.html#ga6ffeecfb574900db4d3161ce0992b8bb">MOZZI_AUDIO_CHANNELS</a>) GPIO pins. Default pinout: PB8 (mono/left), PB9 (right channel in stereo). This mode uses two hardware timers: One for the PWM (Timer 4 when using the default pin configuration), and a second for updating the output at audio rate. The default audio resolution is 10 bits, which results in a carrier frequency of ~70kHz on a 72MHz CPU. On slower boards you will have to descrease this. The following settings may be costumized, if desired:</p>

 <p>This mode is very similar to <a class="el" href="group__hardware.html#stm32_maple_pwm">MOZZI_OUTPUT_PWM</a>, but splitting output for a single channel across two GPIO pins for better resolution. For details on the required hardware setup, and configuration tradeoffs, see <a class="el" href="group__hardware.html#avr_2pin_pwm">MOZZI_OUTPUT_2PIN_PWM</a> . Stereo output is not available in this mode. Output is at 2*7 bits at up to 560kHz carrier frequency (but limited to 5 times audio rate).</p>

 Configuring Mozzi</h1>
-<p>Mozzi configuration options include details such as audio rate, number of audio channels (mono or stereo), output generation method and many others, where details on the available options differ between the different platforms (see <a class="el" href="group__hardware.html">Hardware</a>), and may include additional options beyond those listed, here.</p>

 <dl class="section note"><dt>Note</dt><dd>It is generally safe to leave the Mozzi Configuration unchanged, and that's very much recommended <em>until</em> you have a very specific need to customize something. Contrary to past versions of Mozzi, all configuration options have a (usually sensible) default value, so you do not have to configure <em>anything</em>, unless you actually want to change something.</dd></dl>
-<p>Configuring Mozzi is mostly done using various preprocessor definitions. This approach is used to move as much of the processing involved to compile time, in order to save Flash, RAM, and CPU use at runtime. This section lists various global options, but in addition, most ports allow additional hardware dependent configuration options. See <a class="el" href="group__hardware.html">Hardware</a>.</p>

-<h3><a id="hardware_avr"></a>Mozzi on classic Arduino, Teensy 2.x, Arduino Mega, and other 8 bit &quot;AVR&quot;/ATMEGA architecture boards</h3><div class="textblock"><h1><a class="anchor" id="avr_status"></a>
-Port status and notes</h1>
-<p>This is the original "port" of Mozzi, and thus very elaborate. The main challenges on this platform, compared to other MCUs, are limitations in flash, RAM, and CPU power.</p>
-<h1><a class="anchor" id="avr_output"></a>
-Output modes</h1>
-<p>The following audio modes (see <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a>) are currently supported on this hardware:</p><ul>
-<li>MOZZI_OUTPUT_PWM</li>
-<li>MOZZI_OUTPUT_2PIN_PWM</li>
-<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
-<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
-</ul>
-<p>In all modes, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose. This means, among other things, that pins 9 and 10 cannot be used for analogWrite(), while pins 3 and 11 should still be available <em>except</em> in MOZZI_OUTPUT_2PIN_PWM mode (as Timer2 is also claimed, then; for definite info on which pin is connected to which timer, check a suitable reference, as your board may differ). See <em>Mozzi&gt;examples&gt;11.Communication&gt;Sinewave_PWM_pins_HIFI</em>. for an example of emulating analogWrite() on any digital pin, without the need for a hardware timer.</p>
-<h1><a class="anchor" id="avr_pwm"></a>
-MOZZI_OUTPUT_PWM</h1>
-<p>For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured within this tight limit. In particular, the default setup on the Arduino UNO is:</p><ul>
-<li>Mono: Pin 9 -&gt; configurable using MOZZI_AUDIO_PIN_1</li>
-<li>Stereo: Pin 9 (left) and Pin 10 (right) -&gt; configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2 For pinouts on other boards, refer to config/known_16bit_timers.</li>
-</ul>
-<p>Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.</p>
-<p>The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.</p>
-<h1><a class="anchor" id="avr_2pin_pwm"></a>
-MOZZI_OUTPUT_2PIN_PWM</h1>
-<p>In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for much better dynamic range, providing much more definition than can be achieved using <a class="el" href="group__hardware.html#avr_pwm">MOZZI_OUTPUT_PWM</a> , while using only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see <a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>), which is well beyond the audible range.</p>
-<p>On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient for rapid prototyping. For circuit details, see <a href="https://sensorium.github.io/Mozzi/learn/output/">https://sensorium.github.io/Mozzi/learn/output/</a> .</p>
-<p>On the classic Arduino Uno, the default pinout in this mode is:</p><ul>
-<li>Pin 9 (high bits) and Pin 10 (low bits) -&gt; configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW</li>
-</ul>
-<p>Here is table of the default pins on some other boards. Rows with an x on it have actually been tested (and importantly, the outcome recoreded; input welcome on further boards.)</p>

- For pinouts on other AVR boards, config/known_16bit_timers might contain some hints.</p>
-<p>Rate of the PWM output can be controlled separately from <a class="el" href="group__config.html#gabc7b46bc3dbe1078f411287572226eff">MOZZI_AUDIO_RATE</a>, and is much higher (125kHz), by default: <a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>.</p>
-<p>The default sample resolution is 7 bits per pin, for a total of 14 bits. This can be configured within hardware limits (<a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>) using <a class="el" href="group__config.html#ga9bfd84013cbc04ddb51b31f583178720">MOZZI_AUDIO_BITS_PER_CHANNEL</a>, but beware that increasing this will require even more accuracy in our output resistors (see the linked documentation, above).</p>

-<p>The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used. In a mono configuration, both pins output the same sample.</p>
-<p>TODO: We could really use this to hack in a 2 PIN mode!</p>
-<dl class="section note"><dt>Note</dt><dd>The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that. Check a detailed pinout diagram, if in any doubt.</dd></dl>

-<p>This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins of one I2S interface.

-<p>As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h". This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!</p>

-MOZZI_OUTPUT_PDM_VIA_I2S</h1>
-<p>This mode uses the same setup as <a class="el" href="group__hardware.html#esp32_i2s_dac">MOZZI_OUTPUT_I2S_DAC</a>, but rather than using an external DAC, the communication signal itself is modulated in PDM (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.</p>
-<p>Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.</p>

-<li>Some boards use dedicated cores (e.g. Arduino Giga / Portenta <a class="el" href="group__hardware.html">Mozzi on MBED-based boards (Arduino Giga / Portenta).</a>) etc. For those, see the relevant sections (if we support them).</li>
-<li>There is a series of libmaple-based cores, including <a href="https://github.com/rogerclarkmelbourne/Arduino_STM32">Roger Clark's libmaple-based core</a>. These are highly optimized, and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation via the Arduino Board Manager, and they do not currently seem actively maintained. For using these with Mozzi, see <a class="el" href="group__hardware.html">Mozzi on STM32duino-based boards.</a></li>
-<li>A generic Arduino core for STM32 is the <a href="https://github.com/stm32duino/Arduino_Core_STM32">STM32duino core</a>. It supports a huge set of boards, and seems to have offical backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what the libmaple cores above were known by (don't blame Mozzi for this mess!).

-Status and peculiarities of this port</h1>
-<p>Compiles for and runs on a STM32F103C8T6 blue pill board, with a bunch of caveats (see below), i.e. on a board <em>without</em> a real DAC. Should probably run on any other board supported by <a href="https://github.com/rogerclarkmelbourne/Ardu0ino_STM32">Roger Clark's libmaple-based core</a> (although this theory is untested).</p>
-<dl class="section note"><dt>Note</dt><dd>that at the time of this writing, <a href="https://github.com/stevstrong/Arduino_STM32/">Stev Strong's slightliy more recent fork of this core</a> does <em>not</em> work with Mozzi, apparently due to a bug in pwmWrite().</dd></dl>
-<ul>
-<li>If you want to use MIDI, be sure to replace "MIDI_CREATE_DEFAULT_INSTANCE()" with "MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI)" (or Serial2)</li>
-<li>MOZZI_AUDIO_INPUT_STANDARD is implemented in theory, but untested (feedback welcome)</li>

This mode uses two hardware timers: One for the PWM (Timer 4 when using the default pin configuration), and a second for updating the output at audio rate.

+Port status and notes</h1>
+<p>This is the original "port" of Mozzi, and thus very elaborate. The main challenges on this platform, compared to other MCUs, are limitations in flash, RAM, and CPU power.</p>
+<h1><a class="anchor" id="avr_output"></a>
+Output modes</h1>
+<p>The following audio modes (see <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a>) are currently supported on this hardware:</p><ul>
+<li>MOZZI_OUTPUT_PWM</li>
+<li>MOZZI_OUTPUT_2PIN_PWM</li>
+<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
+</ul>
+<p>In all modes, except MOZZI_OUTPUT_EXTERNAL_CUSTOM, Timer 1 is claimed, and is not available for any other purpose. This means, among other things, that pins 9 and 10 cannot be used for analogWrite(), while pins 3 and 11 should still be available <em>except</em> in MOZZI_OUTPUT_2PIN_PWM mode (as Timer2 is also claimed, then; for definite info on which pin is connected to which timer, check a suitable reference, as your board may differ). See <em>Mozzi&gt;examples&gt;11.Communication&gt;Sinewave_PWM_pins_HIFI</em>. for an example of emulating analogWrite() on any digital pin, without the need for a hardware timer.</p>

+<p>For MOZZI_OUTPUT_PWM, output is restricted to pins that are hardware-attached to Timer 1, but can be configured within this tight limit. In particular, the default setup on the Arduino UNO is:</p><ul>
+<li>Mono: Pin 9 -&gt; configurable using MOZZI_AUDIO_PIN_1</li>
+<li>Stereo: Pin 9 (left) and Pin 10 (right) -&gt; configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_2 For pinouts on other boards, refer to config/known_16bit_timers.</li>
+</ul>
+<p>Rate of the PWM output can be controlled separately from MOZZI_AUDIO_RATE: MOZZI_PWM_RATE.</p>
+<p>The available sample resolution is 488, i.e. almost 9 bits, providing some headroom above the 8 bit table resolution currently used by the oscillators. You can look at the TimerOne library for more info about how interrupt rate and pwm resolution relate.</p>
+<h1><a class="anchor" id="avr_2pin_pwm"></a>
+MOZZI_OUTPUT_2PIN_PWM</h1>
+<p>In this mode, output is split across two pins (again, both connected to Timer 1), with each outputting 7 bits for a total of 14. This allows for much better dynamic range, providing much more definition than can be achieved using <a class="el" href="hardware_avr.html#avr_pwm">MOZZI_OUTPUT_PWM</a> , while using only modestly more processing power. Further, it allows for a much higher PWM carrier rate can be much higher (125 kHz by default; see <a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>), which is well beyond the audible range.</p>
+<p>On the downside, this mode requires an extra hardware timer (Timer2 in addition to Timer1), which may increase compatibility problems with other Arduino libraries that also require a timer. Further, a more elaborate hardware setup is needed, making it less convenient for rapid prototyping. For circuit details, see <a href="https://sensorium.github.io/Mozzi/learn/output/">https://sensorium.github.io/Mozzi/learn/output/</a> .</p>
+<p>On the classic Arduino Uno, the default pinout in this mode is:</p><ul>
+<li>Pin 9 (high bits) and Pin 10 (low bits) -&gt; configurable using MOZZI_AUDIO_PIN_1 and MOZZI_AUDIO_PIN_1_LOW</li>
+</ul>
+<p>Here is table of the default pins on some other boards. Rows with an x on it have actually been tested (and importantly, the outcome recoreded; input welcome on further boards.)</p>

+<p>Rate of the PWM output can be controlled separately from <a class="el" href="group__config.html#gabc7b46bc3dbe1078f411287572226eff">MOZZI_AUDIO_RATE</a>, and is much higher (125kHz), by default: <a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>.</p>
+<p>The default sample resolution is 7 bits per pin, for a total of 14 bits. This can be configured within hardware limits (<a class="el" href="group__config.html#ga3a6d77e502b179f2e490f6151e93414e">MOZZI_PWM_RATE</a>) using <a class="el" href="group__config.html#ga9bfd84013cbc04ddb51b31f583178720">MOZZI_AUDIO_BITS_PER_CHANNEL</a>, but beware that increasing this will require even more accuracy in our output resistors (see the linked documentation, above).</p>

+<li>The implementation of <a class="el" href="group__core.html#ga55fa9d48f327b646c2f71cef7da7b8f0" title="An alternative for Arduino time functions like micros() and millis().">audioTicks()</a> may be slightly inaccurate on this platform.</li>
+</ul>
+<h1><a class="anchor" id="esp32_output"></a>
+Output modes</h1>
+<p>The following audio modes (see <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a>) are currently supported on this hardware:</p><ul>
+<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
+<li>MOZZI_OUTPUT_PDM_VIA_I2S</li>
+<li>MOZZI_OUTPUT_I2S_DAC</li>
+<li>MOZZI_OUTPUT_INTERNAL_DAC</li>
+</ul>
+<p>The default mode is <a class="el" href="hardware_esp32.html#esp32_internal_dac">MOZZI_OUTPUT_INTERNAL_DAC</a> .</p>
+<h1><a class="anchor" id="esp32_internal_dac"></a>
+MOZZI_OUTPUT_INTERNAL_DAC</h1>
+<p>The internal DAC has 8 bit resolution, and outputs to GPIO pins 25 and 26 (non-configurable). For simplicity of code, both pins are always used. In a mono configuration, both pins output the same sample.</p>
+<p>TODO: We could really use this to hack in a 2 PIN mode!</p>
+<dl class="section note"><dt>Note</dt><dd>The number 25 refers to "GPIO 25" or sometimes labelled "D25". Confusingly, many boards come with an additional, totally different numbering scheme on top of that. Check a detailed pinout diagram, if in any doubt.</dd></dl>
+<p>Internally, the inbuilt DAC is connected via an I2S interface. Which interface number to use can be configured using:</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_I2S_PORT     ... </span><span class="comment">// (default: I2S_NUM_0)</span></div>
+</div><!-- fragment --><h1><a class="anchor" id="esp32_i2s_dac"></a>
+MOZZI_OUTPUT_I2S_DAC</h1>
+<p>This mode outputs to a PT8211 (or compatible) I2S DAC, which allows for very high quality (mono or stereo) output. Communication needs the BCK, WS, and DATA(out) pins of one I2S interface. Presumably, any pins qualify, and you can configure this using: </p><div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_I2S_PIN_BCK  ... </span><span class="comment">// (default: 26)</span></div>
+<div class="line"><span class="preprocessor">#define MOZZI_I2S_PIN_WS   ... </span><span class="comment">// (default: 15)</span></div>
+<div class="line"><span class="preprocessor">#define MOZZI_I2S_PIN_DATA ... </span><span class="comment">// (default: 33)</span></div>
+<div class="line">#define MOZZI_I2S_PORT     ... <span class="comment">// (default: I2S_NUM_0)</span></div>
+</div><!-- fragment --><p>See the note above (esp_internal_dac) regarding pin numbering. Also, please always test the default pinout, should a custom setting fail!</p>
+<p>As a technical note, I2S support in the ESP32 SDK has been reworked since this was implemented in Mozzi, and Mozzi uses the "legacy" implementation "i2s.h". This should not be an issue, unless you want to connect additional I2S components, yourself. In which case contributions are certainly welcome!</p>
+<h1><a class="anchor" id="esp32_pdm_via_i2s"></a>
+MOZZI_OUTPUT_PDM_VIA_I2S</h1>
+<p>This mode uses the same setup as <a class="el" href="hardware_esp32.html#esp32_i2s_dac">MOZZI_OUTPUT_I2S_DAC</a>, but rather than using an external DAC, the communication signal itself is modulated in PDM (pulse density modulation) encoded form. Thus not extra hardware is needed, and the signal is output on the DATA pin (see above). The BCK and WS pins are also claimed, but should be left non-connected, and do not produce anything meaningful. This can only be used in mono mode.</p>
+<p>Output resolution may be adjusted by defining MOZZI_PDM_RESOLUTION , where the default value of 4 means that each audio sample is encoded into four 32 bit blocks of ones and zeros. Obviously, more is potentially better, but at the cost of considerable computation power.</p>

+MOZZI_OUTPUT_PDM_VIA_SERIAL</h1>
+<p>Output is coded using pulse density modulation, and sent via the I2S pins. The I2S data out pin (GPIO3, which is also "RX") will have the output, but <em>all</em> I2S output pins (RX, GPIO2 and GPIO15) will be affected. Mozzi tries to set GPIO2 and GPIO15 to input mode, and <em>at the time of this writing</em>, this allows I2S output on RX even on boards such as the ESP01 (where GPIO15 is tied to Ground). However, it seems safest to assume that this mode may not be useable on boards where GPIO2 or GPIO15 are not available as output pins.</p>
+<p>Supports mono output, only, pins not configurable.</p>
+<p>Resolution may be controlled using MOZZI_PDM_RESOLUTION (see above; default value is 2).</p>
+<h1><a class="anchor" id="esp8266_i2s_dac"></a>
+MOZZI_OUTPUT_I2S_DAC</h1>
+<p>Output is sent to an external DAC (such as a PT8211), digitally coded. This is the only mode that supports stereo (<a class="el" href="group__config.html#ga6ffeecfb574900db4d3161ce0992b8bb">MOZZI_AUDIO_CHANNELS</a>). It also needs the least processing power. The pins cannot be configured (GPIO3/RX, GPIO2, and GPIO15).</p>

+<h1><a class="anchor" id="mbed_status"></a>
+Port status and notes</h1>
+<p>Compiles and runs using Arduino's standard and Arduino_AdvancedAnalog libraries. This port is still <b>experimental</b>, testing reveals some instabilities for some configurations (in particular with <a class="el" href="group__config.html#ga40857197e27e3b4d3ee7177e95f59d6d">MOZZI_AUDIO_INPUT</a>) that are under active investigations.</p>
+<p>This port is not complete yet, in particular:</p><ul>
+<li>Asynchroneous analog reads are not implemented (yet), <code><a class="el" href="group__analog.html#gadedb573129313bad0c183af2486c5283" title="See mozziAnalogRead().">mozziAnalogRead()</a></code> relays to <code>analogRead()</code>. (Note that <a class="el" href="group__config.html#ga40857197e27e3b4d3ee7177e95f59d6d">MOZZI_AUDIO_INPUT</a> <em>is</em> implemented!)</li>
+<li>This port should support other MBED based Arduino boards like the Arduino Portenta, in <em>theory</em>, but the developer have only tested it on the Giga. Feedback welcome!</li>
+</ul>
+<h1><a class="anchor" id="mbed_output"></a>
+Output modes</h1>
+<p>The following audio modes (see <a class="el" href="group__config.html#ga9b14b158a7a469612a89dcc9630933b7">MOZZI_AUDIO_MODE</a>) are currently supported on this hardware:</p><ul>
+<li>MOZZI_OUTPUT_EXTERNAL_TIMED</li>
+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>
+<li>MOZZI_OUTPUT_PDM_VIA_SERIAL</li>
+<li>MOZZI_OUTPUT_INTERNAL_DAC</li>
+</ul>
+<p>The default mode is <a class="el" href="hardware_mbed.html#mbed_internal_dac">MOZZI_OUTPUT_INTERNAL_DAC</a> .</p>
+<h1><a class="anchor" id="mbed_internal_dac"></a>
+MOZZI_OUTPUT_INTERNAL_DAC</h1>
+<p>This uses the inbuild DAC on the board. The default is setting is appropriate for the Arduino Giga: 12 bits going to A13 (3.5mm jack connector's tip), and in stereo mode to pin A12 (3.5mm jack connector's first ring) additionally.</p>
+<p>For other boards is may be appropriate to customize: </p><div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_AUDIO_PIN_1   ...   </span><span class="comment">// mono / left channel; default: A13</span></div>
+<div class="line"><span class="preprocessor">#define MOZZI_AUDIO_PIN_2   ...   </span><span class="comment">// stereo only: right channel; default: A12</span></div>
+<div class="line">#define MOZZI_AUDIO_BITS    ...   <span class="comment">// default is 12</span></div>
+</div><!-- fragment --><h1><a class="anchor" id="mbed_pdm_via_serial"></a>
+MOZZI_PDM_VIA_SERIAL</h1>
+<p>Returns a pulse-density modulated (mono only) signal on one of the hardware UARTs of the board (Serial ports). Default is using the SERIAL2, on pin D18. You can confiugre the pins to use, but it must be connected to a hardware UART. Output is written to the TX pin, only, but the RX pin needs to be claimed as well. Beware of confusing pinout labelling, for instance SERIAL2_TX iss labelled "TX1" on the Arduino Giga. The audio resolution can be enhanced using MOZZI_PDM_RESOLUTION, which is described in more detail here: @esp32_pdm_via_i2s .</p>
+<p>Configuration options: </p><div class="fragment"><div class="line"><span class="preprocessor">#define MOZZI_SERIAL_PIN_TX ...    </span><span class="comment">// default: SERIAL2_TX</span></div>

+Port status and notes</h1>
+<p>Compiles and runs using <a href="https://github.com/earlephilhower/arduino-pico">this core</a>. Can probably be ported to the Mbed core for RP2040, relatively easily, as it relies mostly on the RP2040 SDK API. Tested on a Pi Pico.</p>
+<ul>
+<li>This is a recent addition, implementation details may still change (currently just PWM driven by a timer; this may be worth changing to a DMA driven output)</li>
+<li>Wavetables and samples are not kept in progmem on this platform. While apparently speed (of the external flash) is not much of an issue, the data always seems to be copied into RAM, anyway.</li>
+<li>Note that <a class="el" href="group__analog.html#gacd5e655ae9057843ade0d7647f909663" title="See getAudioInput().">getAudioInput()</a> and <a class="el" href="group__analog.html#gadedb573129313bad0c183af2486c5283" title="See mozziAnalogRead().">mozziAnalogRead()</a> return values in the RP2040's full ADC resolution of 0-4095 rather than AVR's 0-1023.</li>

+<li>Code uses only one CPU core</li>

+<li>MOZZI_OUTPUT_EXTERNAL_CUSTOM</li>

+<li>The situation on STM32-based boards is rather confusing, as there are several competing Arduino cores. Importantly:<ul>
+<li>Some boards use dedicated cores (e.g. Arduino Giga / Portenta <a class="el" href="hardware_mbed.html">Mozzi on MBED-based boards (Arduino Giga / Portenta).</a>) etc. For those, see the relevant sections (if we support them).</li>
+<li>There is a series of libmaple-based cores, including <a href="https://github.com/rogerclarkmelbourne/Arduino_STM32">Roger Clark's libmaple-based core</a>. These are highly optimized, and provide very complete support, but only for a limited number of boards. Unfortunately, at the time of this writing (2023/04), they are not available for installation via the Arduino Board Manager, and they do not currently seem actively maintained. For using these with Mozzi, see <a class="el" href="hardware_stm32_maple.html">Mozzi on STM32duino-based boards.</a></li>
+<li>A generic Arduino core for STM32 is the <a href="https://github.com/stm32duino/Arduino_Core_STM32">STM32duino core</a>. It supports a huge set of boards, and seems to have offical backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what the libmaple cores above were known by (don't blame Mozzi for this mess!).

Should probably run on any other board supported by the <a href="https://github.com/stm32duino/Arduino_Core_STM32">STM32duino core</a> (although this theory is untested). When trying any other board, you probably want to check the platform specific settings (see below), carefully, importantly, whether the desired output resolution is achievable, and whether the desired output pins are PWM capable.</p>

 Port status and usage notes</h1>
 <p>Tested on a STM32F103C8T6 blue pill board as well as an STM32F411CE black pill board, i.e. on sboards <em>without</em> a real DAC. Compiles and runs, with a bunch of caveats (see below). Should probably run on any other board supported by the <a href="https://github.com/stm32duino/Arduino_Core_STM32">STM32duino core</a> (although this theory is untested). When trying any other board, you probably want to check the platform specific settings (see below), carefully, importantly, whether the desired output resolution is achievable, and whether the desired output pins are PWM capable.</p>

-## Installation  
-Use the "code" button on Mozzi's Github page to download a ZIP file of the latest developing code.  Import this into Arduino, following the instructions from the [Arduino libraries guide](http://arduino.cc/en/Guide/Libraries).
-
-*In the Arduino IDE, navigate to Sketch > Include Library > Add .ZIP Library. At the top of the drop down list, select the option to "Add .ZIP Library".*
-
-(Note: the files in the "releases" section on Github are now legacy.  The development code is recommended.)
-
-***
-
-## Quick Start  
-To hear Mozzi, connect a 3.5mm audio jack with the centre wire to the PWM output
-on Digital Pin 9 on the Arduino, and the ground to the Ground on the Arduino.
-Use this as a line out which you can plug into your computer and listen to with
-a sound program like [Audacity](http://audacity.sourceforge.net/).

-
-## General caveats and Workarounds
-
-* While Mozzi is running, calling `delay()`, `delayMicroseconds()`, or other functions which wait or cycle through loops can cause audio glitches.
-Mozzi provides `EventDelay()` for scheduling instead of `delay`. In general, make sure to write non-blocking code!
-
-* `analogRead()` is a time-consuming operation especially on the classic AVR boards. Mozzi provides `mozziAnalogRead()` as a drop-in replacement, which works in the
-background instead of blocking the processor.
-
-* Depending on the hardware and configured audio output mode, Mozzi will usually claim one or more hardware timers. This may affect, among other things, the ability to
-use `analogWrite()`. Check the [Hardware Section of the Documentation](https://sensorium.github.io/Mozzi/doc/html/group__hardware.html) to options to configure ressource
-usage.
-  - If you need `analogWrite()`, you can do PWM output on any digital pins using the technique in *Mozzi>examples>11.Communication>Sinewave_PWM_pins_HIFI*.  
-
-* As last resort, the timers can be made available with `stopMozzi()`, which stops audio interrupts, until you call `startMozzi()`.

-## Hardware compatibility and hardware specific notes
-
-While originating on the 8 bit AVR based "classic Arduino" boards, Mozzi supports a wide variety of different MCUs, these days, including:
-  - Classic AVR boards: Arduino Uno, Duemilanove, Nano, Nano 33, Pro Mini, Leonardo, Mega, many others, and countless clones, Teensy 1 and 2.x, ...
-  - Various Teensy 3.x boards: Teensy 3.0/3.1/3.2/3.4/3.5/LC
-  - Teensy 4.x boards: Teensy 4.0 and 4.1 are known to work, future boards stand good chances of working with Mozzi out of the box
-  - STM32-based boards: Confusingly, several popular Arduino cores exist for these MCUs - and Mozzi supports several. Refer to the documentation
-    linked below. Mozzi has been tested on the popule STM32F1 "blue pill" and STM32F4 "black pill" boards, but should support a very wide range
-    of further boards out of the box.
-  - SAMD21-based boards: Tested on the Arduino Circuitplayground M0, expect to work on others, too.
-  - ESP8266: Should run on the whole range of boards, including the minimal ESP-01
-  - ESP32: Should run on the wohle range of boards
-  - Arduiono Giga/MBED: The Arduino Giga, and - in untested theory - the Arduion Portenta
-  - RP2040: The Raspberry Pi Pico and other boards using RP2040
-  - Arduino Uno R4: The new Uno, based on a 32-bit Renesas MCU
-
-Since the hardware capatibilies of these boards are vastly different, the ports, too, differ in their internals and their capabilities. Importantly,
-of course, they also differ in what pin(s) are used for audio output by default. Refer to the [Hardware Section of the Documentation](https://sensorium.github.io/Mozzi/doc/html/group__hardware.html) for the details
-applicable to your hardware.

-## Tweaking Arduino for Faster Audio Code
+## Compatibiliy issues
 
-If you need your synth to run faster on AVR architectures, Arduino versions above 1.5 can be tweaked to optimise compiled code for speed instead of small size.  
+* In most setups, Mozzi claims one or two hardware timers. This may result in incompatibilities with certain libraries, and / or the ability to use timer-based functions such as `analogWrite()`. As the details on this
+  differ a lot between the supported boards, read up on the details - and available workarounds - in the [ardware Section of the API-Documentation](https://sensorium.github.io/Mozzi/doc/html/hardware.html).
 
-Find Arduino’s platform.txt (on OSX you can find it by searching in Users/your_name/Library/Arduino15). Search and replace -Os with -O2. Save.
+* There is also an example on emulating `analogWrite()` on any digitial pin in *Mozzi>examples>11.Communication>Sinewave_PWM_pins_HIFI*.
 
-It’s explained more thoroughly (for Windows) [here](http://www.instructables.com/id/Arduino-IDE-16x-compiler-optimisations-faster-code/?ALLSTEPS).
+* The timers can be made available with `stopMozzi()`, which stops audio interrupts, until you call `startMozzi()`.
 
-If you still need more speed, Arduino 1.0.5 produces slightly faster code.
+* Note that it is of utmost importance to write non-blocking code, such that the
+  audio buffer never runs low. Hints on how to do this, including why, and how you
+  should avoid using `delay()`, `analogRead()`, and how to make your code run faster,
+  can be found at [on the learn pages](https://sensorium.github.io/Mozzi/learn/hints/).
 
-Mozzi itself offers many helpers for producing faster code, such as Fixed-Point integer maths, fast replacements for `map()`, `random()`, `millis()`, and other functions.
-Be sure to use these!

 External chips (DAC) can also be used on any platform which does not support natively the I2S protocol  using an user defined `audioOutput` function. This can allow a greater audio quality over the native ways to output the sound (PWM for AVR Arduinos and STM32 and 12 bit DAC for Teensy 3.*).
 Examples are provided for the MCP492X DAC (12 bit on SPI) and for the (PT8211) 16 bit stereo DAC using SPI port to emulate the I2S protocol. The latter should be compatible with any DAC using I2S.

+### Extendig the library itself
 
 If you enjoy using Mozzi for a project, or have extended it, we would be
 pleased to hear about it and provide support wherever possible. Contribute

+<dl class="section note"><dt>Note</dt><dd>Intialization of the random seed is done differently on different MCUs, but is nowhere near perfect for most (and for some it is not even implemented at all). Many implementations (e.g. on AVR, STM32) simply rely on reading a (hopefully noisy) internal temperature sensor. You will often get better results by calling analogRead() - <em>not</em> mozziAnalogRead(0), in this case! - on one or two floating (non-connected) analog pins. </dd></dl>

Most (all?) platforms support output using an "external" function. When using this option, you will need to provide a suitable definition for audioOutput() in your own sketch, yourself. Some understanding of the general Mozzi audio output architecture may be recommendable, when using this mode: See AudioOutput .In the more simple case (MOZZI_OUTPUT_EXTERNAL_TIMED), Mozzi will still take care of buffering the samples, and calling this function at audio rate (hence "timed"). This generally involves use of a timer, which should be detailed in the <a class="el" href="hardware.html">Hardware and configuration</a> details for your platform.Should you desire even more control - perhaps because your board, or your external DAC already comes with a rate controlled DMA buffer - using MOZZI_OUTPUT_EXTERNAL_CUSTOM also bypasses Mozzis sample buffer. In addition to audioOutput(), you will then need to provide a definition for canBufferAudioOutput(), which will control the rate at which samples are produced. In essence, whenever canBufferAudioOutput() returns true, Mozzi will call <a class="el" href="group__core.html#ga936b78c8ab7a4d7f7075b41e32780d3e" title="This is where you put your audio code.">updateAudio()</a>, and pass the produced sample to audioOutput(), unbuffered. It is entirely your job to make sure that this actually happens at MOZZI_AUDIO_RATE, and / or an appropriate buffer gets used.One additional configuration setting is MOZZI_AUDIO_BITS, which defaults to 16 bits for this mode, but might be set higher, if your hardware supports it.<dl class="section see"><dt>See also</dt><dd><a class="el" href="group__config.html">Mozzi Configuration options</a> </dd></dl>

-<div class="textblock"><p>README! This file is meant to be used as a template when adding support for a new platform. </p>
-<p>Please read these instructions, first.</p>
-<p>Files involved:</p><ol type="1">
-<li>Modify <a class="el" href="hardware__defines_8h_source.html">hardware_defines.h</a>, adding a macro to detect your target platform</li>
-<li>Modify MozziGuts.cpp to include MozziGuts_impl_YOURPLATFORM.hpp</li>
-<li>Modify <a class="el" href="config__checks__generic_8h_source.html">internal/config_checks_generic.h</a> to include internal/config_checks_YOURPLATFORM.h</li>
-<li>Copy this file to MozziGuts_impl_YOURPLATFORM.hpp and adjust as necessary, same for <a class="el" href="config__checks__template_8h_source.html">internal/config_checks_template.h</a> (If your platform is very similar to an existing port, it may instead be better to modify the existing MozziGuts_impl_XYZ.hpp/config_checks_XYZ.h, instead of steps 2-3.). Some platforms may need small modifications to other files as well, e.g. <a class="el" href="mozzi__pgmspace_8h_source.html">mozzi_pgmspace.h</a></li>
-</ol>
-<p>How to implement MozziGuts_impl_YOURPLATFORM.hpp:</p><ul>
-<li>Follow the NOTEs provided in this file</li>
-<li>Read the doc at the top of <a class="el" href="_audio_output_8h_source.html">AudioOutput.h</a> for a better understanding of the basic audio output framework</li>
-<li>Take a peek at existing implementations for other hardware (e.g. TEENSY3/4 is rather complete while also simple at the time of this writing)</li>
-<li>Wait for more documentation to arrive</li>
-<li>Ask when in doubt</li>
-<li>Don't forget to provide a PR when done (it does not have to be perfect; e.g. many ports skip analog input, initially) </li>
-</ul>
+<div class="textblock"><p>Internal. </p>
+<p>Do not use function in this namespace in your sketch!</p>
+<p>This namespace contains various functions that are used by Mozzi, internally, but are not meant to be used in a sketch.</p>
+<p>The details of these may change without warning. I repeat: Do not use these in your sketch! </p>

+<li>Copy this file to MozziGuts_impl_YOURPLATFORM.hpp and adjust as necessary, same for <a class="el" href="config__checks__template_8h_source.html">internal/config_checks_template.h</a> (If your platform is very similar to an existing port, it may instead be better to modify the existing MozziGuts_impl_XYZ.hpp/config_checks_XYZ.h, instead of steps 2-3.). Some platforms may need small modifications to other files as well, e.g. <a class="el" href="mozzi__pgmspace_8h_source.html">mozzi_pgmspace.h</a></li>
+</ol>
+<p>How to implement MozziGuts_impl_YOURPLATFORM.hpp:</p><ul>
+<li>Follow the NOTEs provided in this file</li>
+<li>Read the doc at the top of <a class="el" href="_audio_output_8h_source.html">AudioOutput.h</a> for a better understanding of the basic audio output framework</li>
+<li>Take a peek at existing implementations for other hardware (e.g. TEENSY3/4 is rather complete while also simple at the time of this writing)</li>
+<li>Wait for more documentation to arrive</li>
+<li>Ask when in doubt</li>
+<li>Don't forget to provide a PR when done (it does not have to be perfect; e.g. many ports skip analog input, initially) </li>

+Mozzi 2.0 brings a lot of changes under the hood, and is not 100% source compatible with earlier versions of Mozzi. Most sketches should continue to compile, but with
+a lot of warnings. A few others will no longer work. See [Porting to Mozzi 2.0](https://sensorium.github.io/Mozzi/learn/porting/) for what to change.
+If desparate, there is still a "Mozzi_1" branch in the git repository, but this will not get any new development.

 <li>A generic Arduino core for STM32 is the <a href="https://github.com/stm32duino/Arduino_Core_STM32">STM32duino core</a>. It supports a huge set of boards, and seems to have offical backing by STM, but some features of the libmaple based cores are still lacking. To complete confusion, this core now uses the label "STM32duino", which used to be what the libmaple cores above were known by (don't blame Mozzi for this mess!).
