Description: 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 analysis is, in fact, overtime judgment. If a receiver to the news, some time had not received a EV_RXCHAR, it is a data packet to an end. This thread will receive notification of data threads for da Platform: |
