Background

We use the INA230 for monitoring voltage, current, and power consumption on each power rail. We need to write a driver to interface with the device.

Requirements

• Must provide interface for communicating with multiple sensors. I.e. the driver should not hold any global state shared between sensors.
• Implement function to configure a sensor
• Implement function to get shunt voltage
• Implement function to get bus voltage
• Implement function to get power
• Implement function to get current
• Must validate the driver before merging

Important Information

• Datasheet: https://www.ti.com/lit/ds/symlink/ina230.pdf
• There is a PR up INA230 Load switch pull request #276 but it was never tested
