I need to be able to discover the limited range of motion of a knob I’m turning with a stepper motor. The Allegro 4988 seems to provide a way to watch the motor’s current, which I gather would let me detect when the motor is encountering resistance. First: does that seem plausible?
Second: although the chip provides SENSE1 and SENSE2, I don’t see them broken out on the A4988 carrier board. Is there a way to detect stalls?
