实现了tm4c1294的硬件i2c通信，很方便(The hardware I2C communication of tm4c1294 is realized)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)

一个用AVR单片机ATmega8515输出SPWM波形并驱动一个LED渐亮渐灭的示范程序，输出波形的占空比和频率显示在1602液晶屏上，编译环境Code Vision AVR(AVR with a ATmega8515 SPWM output waveform and an LED driver gradually Liang gradually eliminate the program, the duty cycle output waveform and frequency displayed on the LCD screen 1602, Build Environment Code Vision AVR)

基于51单片机的温湿度控制系统上位机，实现温湿度的动态曲线显示，以及数据采集，监控，excel表格保存(singlechip，humiture，curve,data acquicition, save in excel )

说明：  使用正点原子的精英板/战舰板，使用带FIFO的ov7725 实现普通二值化(Ordinary binarization using the elite plate/warship plate with punctual atoms and ov7725 with FIFO)

一调试好了，放心使用吧，很好的，保证你会满意的。(A debugging good, feel free to use, very good, guarantee that you will be satisfied.)

AT91SAM9263的Keil下的CAN总线的例程文件(AT91SAM9263 under the CAN bus of the Keil routine document)

Thorough application of the C8051 C-language

本实验是关于CC2530的源码，讲的是如何用按键控制LED灯的亮与灭(This experiment is about the CC2530 source tells of how keys to control LED lights on and off light)

对于学习分析时序很有帮助，是一款逻辑分析仪的软件，很有用的。(Timing analysis is useful for learning, is a logic analyzer software, very useful.)
