- Create class 'evaluatedJoystick' - evaluates a joystick with 2 analog signals - scales the adc input to coordinates with detailed tolerances - calculates angle and radius - defines an enum with position information - Add joystick configuration and class instance to config.cpp - Add code for testing the new class to main.cpp - Add joystick.cpp to cmakelists now function `joystick.getData` can be used globally to obtain a struct with current position data of the joystick
