USB接口转换成RS232接口驱动程序，通过串口——USB线即可实现通信-USB interface into RS232 interface driver, through serial port -- USB cable communication can be realized

此代码是用vc编写的多线程的UDP通信聊天室，也可以进行USB通信，可以和下位机进行USB通信-This code is written using vc multi-threaded UDP communication chat rooms can also be USB communication, can be lower computer USB communication

用QT实现局域网内通信，分别用UDP和TCP实现；还有的就是用UDP传输USB摄像头采集到的图像-Use QT realize local area network communication, respectively for UDP and TCP implementation And with the UDP transmission USB webcam is collected image
