USART的驱动程序，在C++编译环境下，进攻学习参考

本程序代码可以准确地生成1－500Hz波形文件，正弦波，方波等。具体功能，下载下来，自己运行一下就知道了-the code can be accurately produce 1-500Hz waveform, sine, square, etc.. Specific functions, downloads, running about themselves will know.

这个是串口的基于停止等待协议原理编程，这个是接收程序，很好用哦-this is the agreement on principle to stop waiting for the program, this is the receiving process, oh well spent
