 Raspberry Pi implementation should be connected to A4988, DRV8825 or any other
 stepper motor drivers with DIR and STEP pin inputs.
 Default config is created for Raspberry Pi 2-3 and this wiring diagram:

 So having Raspberry Pi connected this way, there is no need to configure
 pin map for project.
