本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

This adapter is used to filter contacts on both name and number.

通过单片机控制，实现8个led灯流水显示。(Through the control of the single-chip microcomputer, 8 LED lights are displayed.)

ad7792-ad7793驱动程序，包括： AD7792.c，AD7792.h，Communication.c， Communication.h等等，有应用和参考价值. ADI官网下载。 (ad7792-ad7793 driver, including: AD7792.c, AD7792.h, Communication.c, Communication.h, etc., there are applications and reference value)

SDL2_image-2.0.0开发包，方便大家使用(SDL2_image-2.0.0 Development Kit to facilitate the use)

说明：  注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地(Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land)

基于PCF8591的51单片机温度监测系统，串行AD转换，程序已验证可行，显示准确，含proteus仿真文件(Based on PCF8591 51 single chip temperature monitoring system, serial AD conversion, the program has been verified feasible, accurate display, including proteus simulation file.)

设计并制作一个功率可程控的高效率音频功率放大器及其参数的测量、显示装置。功率放大器的电源电压为+12V（电路其他部分的电源电压不限），负载为8Ω电阻。(Audio amplifier)

说明：  IAR for stm8编译环境和配置参考模板(IAR for stm8 Compilation environment and configuration reference template)

基于STC89C52单片机实现中断LED数码管显示及处理的程序，适合初学值使用(Based STC89C52 MCU interrupt LED digital display and processing procedures, suitable for beginners to use the value)
