ST / Mbed 2 deprecated HelloWorld_IHM01A1

Simple test application for the STMicroelectronics X-NUCLEO-IHM01A1 Stepper Motor Control Expansion Board.

Dependencies:   X_NUCLEO_IHM01A1 mbed

Fork of HelloWorld_IHM01A1 by ST Expansion SW Team

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 one stepper motor connected to the board, moving the rotor to a specific position, with a given speed value, direction of rotation, etc.
