axp173 0.1.2

axp173

What is this?

This is a embedded-hal driver for X-Powers' Power Management IC AXP173.

It's device-agnostic and uses embedded-hal's Write/WriteRead for I2C communication.

Usage

1. Add dependency to Cargo.toml:

   cargo add axp173
   

2. Instantiate and init the device:

   // ... declare and configure your I2c peripheral ...
   
   // Init AXP173 PMIC
   let axp173 = axp173::Axp173::new(i2c);
   axp173.init()?;
   Ok(axp173)
   

3. Configure the PMIC
