# Rust PAC194X Power Monitor Driver

A platform-agnostic driver crate for the Microchip [PAC194X](https://ww1.microchip.com/downloads/en/DeviceDoc/PAC194X-Data-Sheet-20006543.pdf) single/multi channel power monitor using the embedded-hal traits.

[![Build Status](https://github.com/kiranshila/pac194x/workflows/Main/badge.svg)](https://github.com/kiranshila/pac194x/actions)

[![Crates.io](https://img.shields.io/crates/v/pac194x)](https://crates.io/crates/pac194x)

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 `f32`s

## Usage

To use this driver, import this crate and an `embedded_hal` implementation,

then instantiate the appropriate device.

```rust

use linux_embedded_hal::I2cdev;

use pac194x::{PAC194X, AddrSelect};

const SENSE_RESISTOR: f32 = 0.5;

fn main() {

    let i2c = I2cdev::new("/dev/i2c-1").unwrap();

    let mut sensor = PAC194X::new(i2c, AddrSelect::GND).unwrap();

    loop {

        let bus_voltage_1 = sensor.read_bus_voltage_n(1).unwrap();

        let sense_voltage_1 = sensor.read_sense_voltage_n(1).unwrap();

        println!("Channel 1 has a bus voltage of: {:.2} V", bus_voltage_1);

        println!("Channel 1 is pulling a current of: {:.2} A", sense_voltage_1 / SENSE_RESISTOR);

    }

}

```
