Motor Control with the X-NUCLEO-IHM01A1 Expansion Board

This application provides a simple example of usage of the X-NUCLEO-IHM01A1 Stepper Motor Control Expansion Board.
It shows how to use two stepper motors connected to two stacked boards in daisy chain configuration, moving the rotors to specific positions, with given speed values, directions of rotation, etc.
