Motor Control with the X-NUCLEO-IHM02A1 Expansion Board

This application provides a simple example of usage of the X-NUCLEO-IHM02A1 Stepper Motor Control Expansion Board.
It shows how to use two stepper motors connected in daisy chain configuration to the board, moving the rotors to specific positions, with given speed values, direction of rotations, etc.
