51环境的超声波程序，keil直接完美运行，需要复制到程序中(51 microcontroller ultrasound procedure can be run directly keil)

MSP430F5529 MPU6050代码(MSP430F5529 MPU6050 code)

利用easyx写的矩阵键盘仿真，希望可以给爱好者提供参考。(Use easyx wrote matrix keyboard emulation, hoping to provide a reference for enthusiasts.)

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)

模拟电表软件，主要模拟电表数据、遥测数据、参数修改、报文显示、可以模拟2个电表（可以自行修改增加），最终通过RS232转485输出。。。(Analog meter software, the main analog meter data, telemetry data, parameter modification, message displays, you can simulate two meters (which can be modified to increase its own), the final output through the RS232 switch 485. . .)

the function of the code is like a calculator.Basic calculator may be build by the code.

说明：  通过SSDTHOOK技术实现文件隐藏。。(File hidden by SSDTHOOK technology. .)

基于K60的PID调速，飞思卡尔都要用到，很重要的(K60 is based PID control, Freescale must be used, it is important)

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.)

基于蓝牙协议栈BLE4.0的模块CC2541的ADC采集实验(Stack BLE4.0 module CC2541-based Bluetooth protocol ADC acquisition experiment)
