主要是实现调制识别，区分几种常用的数字调制信号。含有两个文件夹 其一为特征参数的仿真；其二为正确识别率的仿真。文件夹key feature simulink中： 运行程序会得到各特征参数之间区分图 从图中可看到特征参数的有效性，见图。 文件夹classification rate simulink中：运行main.m文件 可以得到正确识别率 见图。(It is mainly to realize modulation recognition and distinguish several commonly used digital modulation signals. The simulation of two folders is one of the characteristic parameters, and the second is the simulation of the correct recognition rate. In the folder key feature Simulink: The running program will get the validity of the feature parameters that can be seen from the diagram, as shown in the diagram. Folder classification rate Simulink: running the main.m file can get the correct recognition rate.)

Sample code in VB.NET for calculate and check CRC (Modbus specification). Supported both string format (like MSComm) and bytes array(like DCB).

VS2010串口例程，VC2010写的串口调试助手,开发环境为VS2010,使用的uncioud环境,纯API,不错的C++串行通讯例子程序，希望能对串口学习的朋友有所帮助 (VS2010 serial routines, VC2010 write serial debugging assistant development environment VS2010, using uncioud environment, pure API, a good example of C++ serial communication program, hoping to help a friend learn the serial port)

DXF轨迹图转G代码，有 直线，圆，圆弧，样条曲线，优化多段线，多段线。与下位机串口通讯！无法编译，是因为要先注册mscomm控件(DXF trajectories turn the G-code, line, circle, arc, spline curves to optimize the polyline, polyline. With lower serial communications! Not compile because the first registered mscomm controls)
