画图程序，可以话直线，矩形，圆，椭圆和多边形(Paint program, you can, then straight, rectangular, round, oval and polygon)

由DSP产生正弦扫频信号和幅频特性测量的核心算法和实现过程。按此方案设计的扫频仪，可测得被测网络在20Hz~20KHz范围内的幅频特性，并将测量结果发送给PC机显示(Sine sweep signal generated by the DSP and the core algorithm of the measurement of the amplitude-frequency characteristics and implementation process. Click Sweep program design can be measured by the amplitude of the measured network in the range of 20Hz ~ 20KHz frequency characteristics, and measurement results are sent to the PC display)

28035的GPIO配置例程，实现流水灯相关的功能(28035 GPIO configuration routines for implementing water-light related functions)

使用NPOI处理excel的类文件(create a class to process excel file)

卫星在轨运行的可视化仿真,能够直观、逼真反映卫星的实时轨道和姿态运动。卫星工具软件包( STK)是进行卫星系统仿真和分析的重要工具,能够满足卫星二维和三维的可视化仿真要求。在深 入研究STK/Connect模块的基础上,应用WindowsSockets和多线程编程技术,开发了STK实时视景仿真驱动程序,该程序利用UDP协议接收模拟遥测计算机给出的卫星参数,通过与STK/Connect模块的通信,实时驱动STK的仿真运行,成功实现了卫星在轨运行实时视景仿真的演示效果。(STK (Satellite Too l Kit) STK/Connect)
