用C语言编写的温度采集程序，可以用于C51单片机的开发(Temperature using C language acquisition program, can be used for C51 MCU development)

使用51单片机，用其内部定时中断，和外部中断只找一个可控脉宽调制信号PWM(Using 51, with its internal timer interrupt, and external interrupt only to find a controllable pulse width modulation signal PWM)

对矩阵键盘的程序编写，详细地讲述了如何扫描键盘的输入！(The matrix keyboard programming, detailed tells the story of how to scan the keyboard input!)

基于STM32f103控制HX711和LCD实现的电子秤，软件已调试成功，称重比较准确(Based STM32f103 control the HX711 and LCD electronic scale implementation, the software has debugging success, weighing more accurate)

利用28335的cpu-timer0的中断功能进行AD采集，并有AD校核程序(Use cpu-timer0 interrupt functions of 28335 AD acquisition, and checking procedures AD)

简单的继电保护控制源代码，变压器及线路保护类(Simple relay control source code)

ME850单片机开发实验仪演示程序 - LCD1602显示 基于 c51系列的单片机程序，用AT89S52延时通过(ME850 SCM experimental instrument demo- LCD1602 display based on c51 series SCM process, using AT89S52 delay through)

对RC500卡的读和写，假如刷卡正确的话模块上的LED灯就会亮，没有卡、卡不对、或是其他的不能识别的都不能通过(RC500 card to read and write, if correct module on the card will be light, LED lamp without card and card wrong, or other cannot identify cannot pass)

本程序实现基于单片机的自动电阻测试，包括AD芯片的使用和继电器的控制。(This procedure to achieve automatic resistance measurement based on single chip microcomputer, control and relay includes a AD chip.)
