本代码主要实现SVPWM的算法，主要针对dsp28335。PWM波的频率为10KHz，死去时间2us。(This source code mainly realizes SVPWM and dsp28335 is used.The frequency of pwm is 10Khz and dead band time is 2us)

e4改进NLMS算法的回声消除器研究与DSP实现，挺不错的一篇论文(aec)

说明：  利用Select into生成临时表，使用SQL语句生成数据库中的临时表(Use Select into to generate temporary tables, use SQL statements to generate temporary tables in the database)

输出动态字，可以动态输出两个字，以坐标为处理程序核心(Output dynamic word, you can dynamically output word processing program to coordinate the core)

基于VC++6.0、ODBC、MFC的酒店客房管理程序。数据库为Acess，界面简洁，有详细使用说明。(Based on VC++6.0, ODBC, MFC hotel rooms management procedures. Database for Acess, the interface is simple and has detailed instructions.)

VC6.0实现的，只能有一个程序实例运行的例子程序。两套实现方案。一个使用互斥对象，一个使用找到窗口句柄(VC6.0 achieved, there can be only one instance to run the example program. Two implementations. Use of a mutex object, a window handle to use to find)
