LC709203

A Rust library for interfacing with ON Semiconductor LC709203 battery gauge chips. Based on embedded-hal traits and requires a concrete implementation of at least the i2c::Write and i2c::WriteRead traits.

A platform agnostic Rust driver for the LC709302 battery gauge sensor.

Example usage

// some concrete type implementing I2C access, i.e. the embedded_hal::blocking::i2c::WriteRead
// and embedded_hal::blocking::i2c::Write traits
let i2c = I2C::new();

// create a builder
let lc709203 = lc709203::Builder::default()
    .with_battery_capacity(2500) // battery capacity (specified in mAh) must be set!
    .build(&mut i2c)?; // initialize the lc709203 chip
let battery_voltage = lc709203.cell_voltage_v(&mut i2c)?; // query current battery voltage
