ST / Mbed OS HelloWorld_IHM01A1_mbedOS

Simple test application for the STMicroelectronics X-NUCLEO-IHM01A1 Stepper Motor Control Expansion Board, built against mbed OS.

Dependencies:   X_NUCLEO_IHM01A1

Fork of HelloWorld_IHM01A1 by ST

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.
