Developer @sum_yung_gai@programming.dev

I created a program to control pwm fans through the hardware pwm gpio pins for raspberry pi. I wanted a pwm fan control program that supports hardware pwm, any pwm fan/brand(theoretically), single binary for ease of installation and released with pre-compiled binaries.

All the existing options were either python scripts without hardware pwm or had hard coded pwm control frequencies that wouldn't work with my fan.

Currently the program must be run as root(atleast on my pi4b using pwm on gpio 18), please let me know if you have a solution to this.
