ST / Mbed OS HelloWorld_IHM01A1_2Motors_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_2Motors by ST

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.
