ATK-SIM900A

ftdi公司的USB设备通信上位机编程。(The PC programing for FTDI S USB device)

说明：  该源码实现51单片机之间符合modbus通信协议的通信(This code can achieve communications between MCS51 by modbus protocol. )

用PIC单片机实现带音乐播放的电压表,最高实现3.3V的电压测试(PIC mcu)

通过PWM定时器延迟一秒，实现一个LED灯的明灭。实验中观察I/O口的值对LED灯的明灭的控制，学习I/O口的输入输出方式和设置，了解PWM的配置方式(Through the PWM timer to delay a second, the realization of a LED lamp at. I/O values for LED lamp light control experiment, learning I/O port input and output method and setting, understanding of PWM configuration methods)

通过MFC实现上位机与下位机的串口通讯，可自配置。(Through MFC to achieve the host computer and the next bit machine serial communication, self configuration.)

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)

MSP430实现的多级菜单功能，采用OLED实现，占用Ram量较少(MSP430 realize multi-level menu functions, the use of OLED achieved occupancy of less Ram)

4X4点阵键盘+1602液晶显示做的计算器（AVR单片机）(4X4 matrix keyboard 1602 LCD calculator to do (AVR microcontroller))

C写的ArcSDE连接添加Feature的类(Add ArcSDE Connection C written in class Feature)

能够实现通过红外遥控器控制电机的正反，停止转动。(Can be achieved through an infrared remote control motor forward and reverse, stop turning.)
