kind of optimization design of two phase composite step motor driver based on 8051. The paper mostly intro duces system configuration, communication strategy, control of raise and reduce frequency and so on. At the same time the step motor's microstep control is introduced in detail. The experiment result indicates that the optimization design brings a notable improvement to the dynamic and static performance of the driver
