Abstract
A low overhead controller for microstepping a stepper motor and a low overhead method for microstepping a stepper motor. The reduction in overhead in system processor is accomplished by the control circuit which dynamically interpolates motor positions between steps commanded from the processor. Also, the reduction in overhead is accomplished by a microstepping method used to effect microstepping resolution control by employing a stored look-up table which gives a resolution value at a given speed according to a predetermined function.
