lib.rs:

This is a platform agnostic Rust driver for the INA229, an SPI output current/voltage/power monitor with alerts, using the embedded-hal traits.

This driver allows you to:

• Callibrate the device. See callibrate().
• Read the shunt voltage. See shunt_voltage_nanovolts().
• Read the bus voltage. See bus_voltage_microvolts().
• Read the current. See current_amps().
• Read the power. See power_watts().

The device

The INA229-Q1 is an ultra-precise digital power monitor with a 20-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure a full-scale differential input of ±163.84 mV or ±40.96 mV across a resistive shunt sense element with common-mode voltage support from –0.3 V to +85 V.
