@henrikbrixandersen @MaureenHelm any chance to get another review pass before the end of the year? This is a blocker for us to use upstream drivers |

Update the backend for sensor emulators to include a function for setting the offset as well as a function to query an attribute's metadata such as bounds and increment size. Additionally, add backend support for setting the _xyz channel values. Make the appropriate test changes to accomodate. Signed-off-by: Yuval Peress <[email protected]>
The logic in the driver was not aligned to the datasheet. Also, temperature reading was not being done in fetch, but in channel_get. There was also some extra conversions from SI->register->SI when setting the range, this was causing the register value calculation to produce an incorrect scale in some cases. Tests were added to cover these cases. Signed-off-by: Yuval Peress <[email protected]>
Add support for getting the following attribute values: - SENSOR_ATTR_OFFSET - SENSOR_ATTR_SAMPLING_FREQUENCY - SENSOR_ATTR_FULL_SCALE Signed-off-by: Yuval Peress <[email protected]>
Adding a hook for tests to inject a mock transport and migrating the accel test to test bmi160 specific things. The old version of the test which checks for read values is now covered by the generic test in the sensor build_all target. Signed-off-by: Yuval Peress <[email protected]>
Rename the test directory to more accuratly reflect what's being tested. Signed-off-by: Yuval Peress <[email protected]>
The range map was sorted wrong since the function bmi160_range_to_reg_val() that uses it checks for the user value less than the range component of the bmi160_range struct. This means that no matter what range is set, the value will always end up 2000dps. Signed-off-by: Yuval Peress <[email protected]>
As an example, when the gyro range is set to 250 deg/sec the scale was set to 133 where it really should be 133.160058662. This leads to a 0.12% error in the value returned. By separating the numerator and denominator, we're able to drastically reduce the error. Signed-off-by: Yuval Peress <[email protected]>
