基于nordic soc蓝牙芯片开发的双串口例程。(There is a demo project, which based on ble_app_uart, please place the project under SDK13/examples/ble_peripheral.)

说明：  MCP2515 驱动，直接修改mcp2515.h里面端口即可移植使用。(MCP2515 driver, directly modify the inside ports of mcp2515.h can be transplanted.)

使用STM32f103c8t6输出两路PWm(Using STM32f103c8t6 to output two PWM)

用PSCAD软件编写的燃料电池发电模型，包括逆变器(Fuel cell power generation model)

点亮小灯，针对51单片机系统，简单实用，操作简单，具有可移植性(lighten the light)

利用单片机IO口模拟UART程序,系统用了一个定时器和一个外部中断,外部中断主要是用来检测串口起始位的到来。(IO mouth simulation UART program, microcontroller system with a timer and an external interrupt, external interrupt is mainly used to detect the arrival of the start bit serial port.)

基于C8051F020单片机的液晶驱动程序，通过编译、链接，调试没有错误，压缩包里有C程序号头文件以及源程序的汇编版本。(C8051F020-based single-chip LCD driver, through the compile, link, debug, no errors, compression bag has C header files, as well as procedures for its source code version of the compilation.)

动压气体轴承的动态刚度和动态阻尼系数 (Dynamic pressure gas bearing dynamic stiffness and dynamic damping)

More testing with arduino for cs1180 and 485 micro.

基于STM32的简易电子琴。采用STM32F103ZET6主控芯片，矩阵键盘和无源蜂鸣器实现简易电子琴功能。(Electronic organ)
