利用windowsAPI（非组建/控件等）编写的comm通信程序库，能够实现comm单字节/多数据发送接收，延时处理等。使用前如不调用.h中的初始化函数，则使用默认频率。.c文件为一个小的测试程序，使用时包含.h即可。-The use of windowsAPI (non-set up/control, etc.) prepared comm communication library, to achieve single-byte comm/data to send more than rec

通过介绍SetTimer函数，来计算通信延时。在VC下得到精确延时时间，而sleep函数是完成不了的-By introducing the SetTimer function to calculate the communication time delay. In the next VC to be accurate delay time, and can not sleep function is to complete

制作了一个延时开和延时关的结构，该结构采用线程来完成两个功能，可以实现IO板卡的信号输出并且调用函数后立刻返回，不会阻塞程序-Produced a time delay and delay-related open structure that uses the thread to complete the two functions can be achieved IO board and the signal output after the function call returns im

包含：833us延时程序，接收的数据处理函数，接收一个字符函数，字符串发送函数-Contains: 833us delay procedure, the receiving data processing functions, receiving a character function, the string sending function
