This thesis also simulates that under the system of singlechip stepping motor speed control has the disadvantages of changing speed、 time arbitrary、 Positive and negative transfer、 installation of accelerated and deceleration、 lowpower system and online debugging. Singlechip as core of control and the circuit made up by active crystal as clock signal, the stepper motor speed control system starts to making a series of necessary judgment and then control rotate speed and change direction when it receive the mand of stepper transfer control from singlechip control system by keyboard. As run steady, this project has already passed the simulation and has achieved the basic purpose. This project consists of two parties. One is hardware circuit and the other is software programming. In the part of hardware circuit is include active crystal、 control system of keyboard input 、 system of motor drive circuit and liquid crystal system. In the second part, Design of connection of singlechip、software prepared is the mainly prepared of Subroutine and Main program including initialization code 、 liquid drive code 、 the timing of recording code form data code[8]. Key words: MCU； stepper motor； 12864LCD； Instruction Set.
