Abstract
Controlling a stepper motor. A stepper motor is driven towards an index position. An attempt is made to stop the stepper motor on the index position in a fashion that would ordinarily cause the stepper motor to ring at the index position. Characteristics of one or more subsequent pulses that would counteract the ringing are determined. The one or more determined subsequent pulses are issued to the stepper motor.
