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.)

由单片机和DAC0832产生正弦波或三角波的程序。单片机和DAC0832可将频率进行分频的具体程序(Sine or triangle wave and DAC0832 procedures generated by the microcontroller. SCM and DAC0832 can divide the frequency of specific procedures)

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))
