proteus的数字电压表仿真程序源代码及电路图。(The digital voltmeter proteus simulation program source code and the circuit diagram.)

关于与计算机超级终端通讯的小程序.(RS232)(HyperTerminal on the computer applet communication. (RS232))

适用于韦根26与34的通讯，基于stm32开发，自动切换，方便，兼容性强(It is suitable for communication between Wigan 26 and 34. It is developed based on stm32. It has automatic switching, convenience and strong compatibility.)

对初学单片机非常实用的一些小程序老师写的 这是第二部分(right novice SCM some very practical procedures for the teacher to write small, which is the second part)

说明：  它是关于80C51单片机的原理介绍和使用其开发的过程，有具体的实例。(It was introduced on the 80C51 microcontroller and use the principle of its development process, with specific examples.)

说明：  步进电机L298N可调速msp430控制调试成功(Stepper motor L298N can be governor the msp430 control debugging success)

电子设备的接触不良原因分析，分析的很深刻。(Electronic equipment is bad cause analysis, very deep.)

基于STM32的4轴步进电机加减速控制全套工程源码，共有两套； 一套是STM32F103的，另外一套是STM32F405的； 可以同时控制4轴步进电机进行加减速； 速率可以达到100K以上； (4-axis stepper motor control acceleration and deceleration based STM32 full project source code, there are two Set is STM32F103 and STM32F405 is another set of Can simultaneously control four-axis stepper motor acceleration and deceleration Rate can reach more than 100K)

基于STM32F103利用SPI协议，RC522多功能读取，修改，删除卡片(Based on STM32F103 and SPI protocol, RC522 can read, modify and delete cards with multiple functions.)
