3.3.1.1.2 Step Mode

The DRV8428P EVM provides the ability to operate a stepper motor in full step mode. The firmware provides the necessary timing pulses on the AINx/BINx input signals to drive the stepper at the desired speed and direction.

To use the stepper feature, set the “Control Mode” toggle to “Step”.
