a PWM fan controller built for the Raspberry Pi 4 & Noctua NF-A4x10 5V PWM
i'm running ubuntu so I build with GOOS=linux GOARCH=arm go build ..
sudo ./GoFan
root is required to use PWM pins
run with sudo BACKGROUND="anything but empty string" ./GoFan & to run as a background process
BACKGROUND changes logging behavior. If this var is present, logs are not printed to the console and are instead written to logfile TODOLOL yeeted to the void
DriftKingTw's pi PWM fan was the main source I used in building this, with the main difference being the use of Golang instead of Python to write the fan controller
Check out their guide for pin setups & general PWM fan theory!
