本文利用单片机实现对步进电机的正反转、速度及转动角度控制，资源包中包括8051汇编源代码、对应的protues仿真电路，通过protues的仿真，可以看到实际的运行效果 -DSP source code for the stepper motor can be run directly, is ideal for beginners debugging test programs, you can also add protect the drive motor.

基于汇编的计算器功能内含protues仿真，基本的四则混合混算功能-Calculator based on implicit protues compiled simulation, the basic function of four mixed mixed operators
