Abstract
A microprocessor controls the operation of a stepper motor. A look-up table containing a sequence of numbers is used to generate up ramp or down ramp speed control of the stepper motor. The microprocessor supplies numbers from the look-up table to a stepper motor speed control, which causes the stepper motor to step at rates determined by the numbers supplied by the microprocessor.
