Setup Raspberry Pi GPIO pins using a configuration file, not boilerplate.
Boilerplate code is annoying and sometimes there can be a lot of it working with Raspberry Pi GPIO (RPi.GPIO). I got tired of setting the board mode and declaring GPIO channels in every script so I made a library that uses a config file instead. In addition to getting rid of the boilerplate, Pi-Pin-Manager offers a cleaner interface for working with RPi.GPIO.
