CserialPort类源码

串口温度数据采集并实时显示 读串口数据的原理是,只要当有数据向串口发数据来时,计算机就会自动将其数据写到一个特定的缓冲区,我们只要写程序去读那个特定的缓冲区就可以了. 有数据向串口发过来时,程序可以将数据接收到,接收的数据是字符型的,那么将数据转化为数字型的,再将这个数据的大小作为画图的某一个点的纵坐标,横坐标为数据的序号.将这些点用线连起来就是一个曲线图了,这个就是图形显示基本原理. 查看原来的数据的原理也是这样的,不同的地方就是,数据是从文件中来,同样的也是将多个数据分成一个一个的,然后这一个数据的大小就是画图的某一个点的纵坐标,横坐标同样为数据的序号,再将这些点用线连起来就是曲线图. 图形能移动的原理,是我们首先改变的只是数据,图形并没有变,但图形的形式是由这些数据来确定的,当数据发生变化后,我们通过刷新显示区来变化的.(Serial temperature data acquisition and real-time serial data reading the principle is, as long as when a serial data to the data, the computer will automatically writes data to a specific buffer, we can write specific procedures read that the buffer zone would be fine. Serial data to be sent, process data can be received, the receiving of data is the character, then transform data into digital type, and then the size of the data as a drawing of a point Ordinate, the abscissa serial data. these points will be used to link line is a curve, this is the graphic display the basic tenets. View the original data is the same principle, the difference is, the data from the file, the same data also will be divided into a number one, and then this one is the size of the data to draw a certain point )

串口调试：这还是个初步的！如果你有兴趣还可以自己再改！如果还有更好的请联系我(serial debugger : This is still preliminary. If you are interested in then they can change! If there is a better contact I)

串口程序实现Ymodem协议，也可以使用TCPIP实现Ymodem协议。 串口和网络程序都可以当一个助手使用。(Serial procedures to achieve Ymodem protocol, you can also use TCPIP achieve Ymodem protocol. Serial and network programs can use when an assistant.)

把SerialPort通讯类封装成的DLL+使用例子(SerialPort Dll and demo)

说明：  Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

XWP仪表参数的读取，是帮1个朋友编写的(Instrument parameters XWP read, is to help a friend prepare the)

调试串口的程序，本程序运行于PC机，是开发串口电路的好帮手。(Debug serial procedures, the program runs on PC, is to develop a good helper serial circuit.)

一个功能比较全面的串口调试工具。你值得拥有。(A more comprehensive functional serial debugging tools. You deserve. )

VC实现和S7-200PLC的串口通信程序,很有价值哦(VC and S7-200PLC Serial Communication Program and of great value oh)

vc++ 串口编程,用vc++编写上上位机程序 常见的几种方式以及注意事项均有介绍
