Fork of X-NUCLEO-IHM05A1 by ST Expansion SW Team

Motor Control Library

Library to handle the X-NUCLEO-IHM05A1 Motor Control Expansion Board based on the L6208 component.

It features the:

  • Read and write of device parameters
  • Configuration of GPIOs and IRQs (for enabling, direction, current decay and microstepping)
  • Control of position, speed, acceleration and deceleration
  • Command locking until the device completes movement
  • Handling of overcurrent and thermal alarms (flag interrupt handling)

The API allows to easily:

  • perform various positioning, moves and stops
  • get/set or monitor the motor positions
  • set home position and mark another position
  • get/set minimum and maximum speed
  • get current speed
  • get/set acceleration and deceleration
  • get/set the step mode (up to 1/16)

Platform compatibility

Compatible platforms have been tested with the configurations provided by the HelloWorld_IHM05A1 example.
