A PI-Controller to control the beam position implemented digitally on an Arduino which can be mounted on a PCB which contains the necessary level-conversions and a multi-channel DAC.
This repository contains all the necessary files to replicate the implemented controller. In devices one finds the .ino and .cpp libraries for the controller itself as well as a .py script to communicate with it.
The KiCaD-folder contains the .kicad_pro for the arduino shield and its .gbr files.
