类的继承与派生的几道练习题，内有题的大意(Class inheritance and derived)

1） 从网络采集实时数据：在软件运行过程中，可以实时地从网络上根据自定义的通信协议采集数据，并且按照层次结构显示在主界面中。 2） 自动生成数据表：在服务器程序初次运行时，创建数据库，并且随着程序的进行在数据库中根据收到的数据生成数据表。 3） 历史数据存储功能：从网络上采集的数据值只要发生变化，就会存储到历史数据表中。 -a) real-time data acquisition networks : the software process, in real time from the network on the basis of communications from the definition of data acquisition agreement, in accordance with the hierarchy shown in the main interface. 2) Automatic Generation Data Sheet : in the initial operation of the server, database creation, and with the conduct of the proceedings in the database according to the data received generate data sheets. 3) Historical data storage functions : collection from the network as long as the data values change, it will store historical data table.

用DSP28335实现三电平SVPWM整流器的程序，用到了12路PWM波，60°坐标系的的矢量算法。(DSP28335 achieved using a three-level SVPWM rectifier procedures used 12 PWM wave vector algorithm 60 ° coordinate system.)

这是DSP F2812的CAN总线功能配置程序，希望对大家有用！(This is a DSP F2812 features CAN bus configuration program, we hope to useful!)
