提出了一个由AT89C52单片机控制步进电机的实例。可以通过键盘输入相关数据, 并 根据需要, 实时对步进电机工作方式进行设置, 具有实时性和交互性的特点。该系统可应用于 步进电机控制的大多数场合。实践表明, 系统性能优于传统的步进电机控制器。-Put forward a AT89C52 single-chip stepper motor control example. Through the keyboard input data, and in accordance with the needs of real-time work on the stepper motor set up, with real-time and interactive features. The system can be applied to stepper motor control of the majority of occasions. Practice shows that system performance is superior to traditional stepper motor controller.

通过键盘控制，选择max262不同的工作方式（低通，高通，带通）。用‘+’，‘-’及数字键来控制不同的中心频率，该文件就有详细的正确的C51程序及部分仿真电路。该源代码经过实际验证。-max262--Programmable Filtering
