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: 串口通信的概念非常简单，串口按位（bit）发送和接收字节。尽管比按字节（byte）的并行通信慢，但是串口可以在使用一根线发送数据的同时用另一根线接收数据。它很简单并且能够实现远距离通信。比如IEEE488定义并行通行状态时，规定设备线总常不得超过20米，并且任意两个设备间的长度不得超过2米；而对于串口而言，长度可达1200米。典型地，串口用于ASCII码字符的传输。通信使用3根线完成：（1）地线，（2）发送，（3）接收。由于串口通信是异步的，端口能够在一根线上发送数据同时在另一根线上接收数据。其他线用于握手，但是不是必须的。串口通信最重要的参数是波特率、数据位、停止位和奇偶校验。-The concept of serial communication is very simple, serial by bit (bit) to send and receive bytes. Although more than by byte (byte) of parallel communication slow, but can use a serial line to send data at the same time another line to receive data. It is very simple and can achieve long-distance communications. For example, the definition of IEEE488 parallel access mode, the total line often provides equipment shall not be more than 20 meters, and between any two devices may not be more than two meters in length and in terms of the serial port, up to 1200 meters in length. Typically, serial code for the ASCII character transmission. 3 lines of communication to use to complete: (1) ground, (2) send, (3) to receive. Due to the asynchronous serial communication port to send data in a line at the same time another line to receive data. Other lines for the handshake, but not necessary. Serial communication the most important parameter is the baud rate, data bits, stop bits and parity.
