本程序是i2c总线读写一个字节的程序。在写过程序中，不一定非要检测i2c的应答位，可以直接延时过去就行，但是在读过程中必须给应答信号，读完发停止位，一定确认所发...

从串口读取数据，有两种方法， 1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。 2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data

该程序是不占用资源的串口数据捕捉.同一台计算机中,再有其他应用程序或设备同时占用一个或多个串口的情况下,捕捉这些串口的通信数据,显示在界面上,并可保存-that the procedure was not occupied resources serial data capture. Same computer, we have other applications or devices occupying one or more serial circumstances, the capture of these serial data communications, and display the interface and can be preserved
