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接收,其实就是第一种方法的变种: 一个侦听EV_RXCHAR,一个对EV_RXCHAR进行分析,其实就是超时判断。如果接收到一个消息后,一段时间没收到下一个EV_RXCHAR,就认为是一个数据包的结束。这个线程就会通知数据接收线程,进行数据接收。一般同一包数据,两个字符之间的时间间隔,应该很小了吧,而两个数据包之间的间隔,应该不会太小吧!(这个地方我不清楚,猜的:( :) )最后一个线程,是接收数据的。-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 reception, the first method is a variant : an interception EV_RXCHAR, one pair of EV_RXCHAR analys
