ST / Mbed OS MotorControl_IHM01A1_mbedOS

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

Motor Control with the X-NUCLEO-IHM01A1 Expansion Board

This application provides a more complex 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, with an example of ISR and error handler, as well as an almost complete coverage of the available APIs, e.g.:

  • moving the rotor to a specific position;
  • moving the rotor for a certain amount of time;
  • setting the speed value;
  • setting the direction of rotation;
  • changing the stepper motor mode;
  • soft/hard stopping the rotor;
  • powering off the power bridge.
