又来了~~继上次之后的又一重磅出击，本程序也是图形填充(Here we go again ~ ~ Following the last after another heavy attack, the process is filled with graphics)

OpenGL FPS sample. + bird eye view(OpenGL FPS sample.+ bird eye view)

微分先行PID算法，MATLAB语言编写，仿真效果不错。(Differential first PID algorithm, MATLAB language, simulation results are good.)

这是一个网上书店系统，除了具有一般的网站功能以外，计划开展独创用户交流购书体验，以实用有用为目的，使用户知道同类书籍自己应该选择哪本，或者是自己要学习某部分知识。(This is an online bookstore system, in addition to the general site features, plans to carry out original user exchange book purchase experience, practical and useful for the purpose of allowing users to know which books should choose their own, or their own to learn part of the knowledge.)

说明：  UCOS III操作系统培训教程，非常好的文件，入门学习！(UCOS III operating system training tutorial, very good documentation, the beginning of learning!)

Every blogger dreams of making a lot of money online and most of them want to make a lot of money online particularly from Google Adsense

白噪声产生程序，使用C++编程，适合初级系统辨识的研究人员使用(whilte noise)

说明：  摄像头两轮原理图pcb完整版大小结构都十分精确适合飞思卡尔竞赛(The size and structure of the complete PCB version of the two rounds of the camera schematic are very precise and suitable for Freescale competition)

STM8L151的SI4463/SI4438的驱动程序，433MHz、915MHz都可以适用，晶振26MHz。

程序是要建立一个哈弗曼树，并利用哈夫曼树求相应编码和译码，根据输入的一串电文（字符串）来设计哈夫曼树，并根据哈弗曼树求出每个字符相应的编码，最后根据已知的编码，随机组合输入编码串，根据哈弗曼编码和哈弗曼树求出译码内容。 主要输入形式为一串字符串例如：abcd 输入的范围就是这26个字母，不限大小写，定义最多输入的字符不超过100个。 输出的形式根据要求，输入字符串后，要输出每个字符及其权值（出现次数）； 然后再输入要译码的编码串，输出译码内容。
