RE: DRV8711EVM: Reaching Desired RPS with 1/2 step

Hi Griffin,

The motor can stall based on several events. Generally it is one of the following:

the motor is accelerated/decelerated too quickly from one speed to another
the current cannot be inserted or removed quickly enough as the step current is changed
too little current is set for the motor

If you have a current probe, please examine the current in the motor to determine if you are getting the specified amount. If you are not, this can be remedied by:

Raising the VM voltage - this will allow more current at each step.
Changing the step rate to full step, and lowering the pulses/second
Slowly accelerating/decelerating from 0 to the desired speed.
