power electronic machine model

使用读卡器实现了为个人化的IC卡数据读写(Achieved using the reader for personal IC card data read and write)

在51单片机上实现RS485通讯，能够实现与上位机的通信(RS485 mode on 51 single, able to communicate with the host computer)

智能车PID控制，非常不错的讲述PId原理的文献(Smart car PID control, very good about the principles of literature PId)

用普通遥控器做的电脑鼠标，遥控器发送数据，51单片机解码，通过串口发送到上位机上，在上位机上运行程序，实现鼠标控制(Do with an ordinary remote control computer mouse, the remote control to send data, 51 single-chip decoder, sent through the serial port to the PC, run the program on the host computer, mouse control)

点阵液晶屏的参考程序，内置菜单动能，大家可以研究一下(Dot matrix LCD screen reference program, built-in menu kinetic energy, we can look)

基于AT89C51单片机的出租车计价器的程序设计(AT89C51 microcontroller Taximeter-based program design)

STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))
