Targets aarch64-unknown-linux-gnu architecture, uses the GPIO/I2C on the Raspberry Pi Zero 2W to show status of the MakerPower MPPT board.
Currently just outputs to STDOUT.
Cross-compile from a PC/Mac with cross with the command:
cross build --target aarch64-unknown-linux-gnu
and copy the file in target/aarch64-unknown-linux-gnu/debug called pi-makerpower-gpio to your Raspberry Pi Zero 2W.
- Read "alert" GPIO pin to trigger system shut down
- Output to file so webserver can render values of charging, battery voltage, figure out charge level.
- Other types of output?
