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: |

Description: 我主要是通过串口来实时采集GPS得同步数据，频率20HZ，而且数据长度（均大于200个字符）是变化的，每次都要提取里面有用的数据。所取数据用于汽车试验参数。
本人分别采用两种方式来实时读取串口数据：一种是大家常用的ＶＩＳＡ控件； 另一种是调用Mscomm。本人在使用中感觉后一种通讯方式很好！
-I mainly collected through the serial port in real-time GPS data were synchronized, frequency 20HZ, and the data length (all greater than 200 characters) is the change, inside each time extracting useful data. The obtained data are used for automotive test parameters.
I were used in two ways to read data from serial port in real-time: one is our common VISA controls the other is called Mscomm. I use the feeling of a good means of communication! Platform: |
