Rust PAC194X Power Monitor Driver

A platform-agnostic driver crate for the Microchip PAC194X single/multi channel power monitor using the embedded-hal traits.

This driver allows you to:

• Read/Write every available register as a Rust data structure, allowing you to configure alerts, averaging, etc.
• Read the bus and sense voltages directly as f32s

Usage

To use this driver, import this crate and an embedded_hal implementation, then instantiate the appropriate device. See the examples folder for example code.

Run it on Linux with cargo build --examples linux && sudo ./target/debug/examples/linux. It's hardcoded to bus /dev/i2c-3 and I2C address 0b10000 (grounded).

I wrote a blog post about the development of this crate here
