支持SD卡的MP3电路图,powerpcb4.0格式.使用AVR单片机

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.

数码管的显示操作，同时也有按键操作程序，通过单片机控制可以直接进行显示-Digital tube display operation, but also has key operating procedures, can be directly controlled through the single-chip display

这是单片机多机通信的C源码程序，供大家参考。-This is a multi-machine communication C source programs, for your reference.

这是一个基于MCU的电机控制系统，单片机接收PC的信息，根据Modbus通信协议转换为相应电机控制命令。 整个程序在keil环境下开发，实现了电机的启动、停止、增速、减速、反馈运行时间和速度的功能。-This an MCU-based motor control system, the 8031 PC receiving the information, according to Modbus communication protocol conversion to the corresponding motor control commands. Keil in the whole process environment in development and the launch of the motor, stop, the growth rate, deceleration, feedback running time and speed functions.
