说明：  介绍了一种基于仿真软件PROTEUS的单片机步进电机控制系统的仿真应用。整个系 统以AT89C51单片机为控制核心，利用单片机自身的定时中断、I/U输出，并与一些外围器件等有机结合起来，实现采用按键对步进电机的连续调速、实时控制与显示步进电机工作方式等功能。同时，采用C语言进行系统的软件编程，并在PROTEUS环境下通过了仿真验证。
(A simulation application of stepping motor control system based on PROTEUS is introduced. Whole Department With AT89C51 as the control core, the system uses the timing interruption and I/U output of the single chip computer itself, and combines with some peripheral devices to realize the functions of continuous speed regulation, real-time control and display of the working mode of the stepper motor by using keys. At the same time, C language is used to program the software of the system, and it has passed the simulation verification under the environment of PROTEUS.)
