基于STM32的双串口通信程序，能实现两个串口的收发，程序默认采用串口2接收数据，串口1发送(Based on the STM32 dual serial communication procedures, can achieve two serial transceivers, the program defaults to the serial port 2 receives the data, send the serial port 1)

说明：  通过计算机25针并口读写SPI总线Flash存储器(25-pin through the computer parallel port read and write SPI bus Flash memory)

通过反转法循环扫描矩阵键盘，并通过数码管显示数据(By inversion method cyclic scan matrix keyboard, and through the digital display data)

电子时钟程序，简洁明了，原创请勿抄袭 适用于stc15单片机(Electronic clock program)

说明：  模糊PID控制器,解决了规则爆炸的问题,同时改善了系统的动态性能和实时性(Fuzzy PID controller to solve the rule explosion problem, while improving the system dynamic performance and real-time)

单片机常用芯片手册,非常实用,初学者适合(Commonly used single-chip chip manual, very practical, suitable for beginners)

用诺基亚5110显示的悬挂运动控制系统，完美的运行了寻点，直线，画圆，循迹的程序没加进去，如果想要的话发信息至1551142817@qq.com(Nokia 5110 display with a suspension motion control system, running to find the perfect point, line, circle, tracking program not added, if desired send a message to 1551142817@qq.com)

基于atmega16l usart的实现(atmega16 usart)
