说明：  由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)

单片机红外遥控系统 ，该文章详细的介绍了用单片机实现红外遥控。(SCM infrared remote control system, the article describes in detail the infrared remote control with MCU.)

基于cortex-M3的TCP客户端程序，有上位机软件，及MCU的驱动程序，使用LWIP协议栈。(cortex-m3，lwip，TCP/IP)

说明：  用C语言编写的51单片机智能小车程序；该小车能自行循迹，超声波避障和测距，液晶显示信息以及红外遥控等功能；(The 51 single-chip intelligent car program written in C language can track itself, avoid obstacles and measure distance by ultrasound, display information by LCD and infrared remote control.)

说明：  看电子电路时序图如何看，这是个好方面，可以看看(Electronic circuit timing diagram to see how the look, this is a good side, you can see)

说明：  下面的程序利用友元函数求两点间的距离。请你将有关的程序补充完整，并总结为什么这里要用友元函数来求两点间的距离。(using friend to get the result.)

说明：  51单片机红外线遥控解码，4位led显示，多路继电器控制(Infrared remote control decoding, LED display, relay control)

使用FFMPEG库进行视频解码，然后在一个Static控件上使用SDL2.0进行视频显示，相比SDL1.0,2.0版本支持多窗口同时显示，性能也大幅提升。（demo中未处理音频帧）。本Demo优点：将视频解码和显示分别封装了两个类CFfmpegDecod和CSdlShow，便于学习和理解播放流程。适合学习者使用。(Using the FFMPEG library for video decoding, and then on a Static control on the use of SDL2.0 video display, compared to the SDL1.0,2.0 version supports multi window at the same time, performance is also greatly improved. (demo is not processed for audio frames). The Demo advantages: the video decoding and display are encapsulated in two classes CFfmpegDecod and CSdlShow, easy to learn and understand the playback process. Suitable for learners to use.)
