UART

基于51单片机的32和弦音乐盒程序，有曲目切换，音量调节，播放时间，步进电机驱动，流水灯等功能，是普通音乐的升级版本，且代码清晰，注释完整，结构合理。(Based on 51 single-chip 32 polyphonic music box procedures, switch tracks, adjust volume, play time, stepper motor drive, water lights and other functions, is an upgraded version of the ordinary music and clear code, comments, integrity, reasonable structure.)

NUAA微机实验课设：1.密码确认。2.数据采集控制系统。3.数码管显示(NUAA Computer Lab located: a password confirmation. 2 Data acquisition and control system. 3 digital display)

说明：  红外编码发生器程序 自己编写 调试成功 大家可以看看(IR code generator program written to debug their success we can see)

通过51单片机实现串口通信，并在外接LED显示器上显示。(51 microcontroller via serial communications, and displayed on an external LED display.)

利用Arduino实现读取MPU6050的DMP四元数(Arduino MCU reads MPU6050 use a DMP quaternion)

it is program for led matrix

stm32芯片--用GPIO口模拟I2C驱动MPU6050陀螺仪(Stm32 chip- using GPIO port simulation I2C driver MPU6050 gyroscope)

说明：  一个特别好的modbus从机扫描程序，可以以RTU或ASCII方式通信以此来检验下位机。(A particularly good modbus slave scanner can communicate with RTU or ASCII way to test this lower position.)

C++电梯模拟程序，同过仿真的方式在控制台下测试其电梯程序的准确性(elevator simulation)

PIC （PIC16F886） 做的简单频率计 用TMR0定时1s，将待测信号从T1CKI脚输入，用TMR1进行计数，读出TMR1H，TMR1L的值就是频率 单片机：PIC16F886 显示：LCD1602 编程语言：PIC C 附Proteus仿真。(PIC (PIC16F886) to do a simple frequency counter TMR0 timer with 1s, the test signal input pin from T1CKI with TMR1 count, read TMR1H, TMR1L value is the frequency of the microcontroller: PIC16F886 display: LCD1602 with Proteus simulation.)
