Study on Speep-up/down and Precision Control of Step Motor Based on Single-chip Microcomputer

The hardware structure of the control of step motor using single-chinp microcomputer was introduced in this paper.on this basis,put forward three ways to realize the speed-up of step motor.In the last,analysed the influence of timing error of shigle-chinp microcomputer in the control of step motor,then gave the way to solve this problem.
