Module capsules::max17205

Driver for the Maxim MAX17205 fuel gauge.

https://www.maximintegrated.com/en/products/power/battery-management/MAX17205.html

The MAX1720x/MAX1721x are ultra-low power stand-alone fuel gauge ICs that implement the Maxim ModelGauge™ m5 algorithm without requiring host interaction for configuration. This feature makes the MAX1720x/MAX1721x excellent pack-side fuel gauges. The MAX17201/MAX17211 monitor a single cell pack. The MAX17205/MAX17215 monitor and balance a 2S or 3S pack or monitor a multiple-series cell pack.

Usage

// Two i2c addresses are necessary.
// Registers 0x000-0x0FF are accessed by address 0x36.
// Registers 0x100-0x1FF are accessed by address 0x0B.

let max17205_i2c_upper = static_init!(
    capsules::virtual_i2c::I2CDevice,
    capsules::virtual_i2c::I2CDevice::new(i2c_bus, 0x0B));
