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 )

用visual c++写的串口通信程序,有rs232,同步串口通信,不错的(Written in visual c++ serial communication program, rs232, synchronous serial port communication, good)

VC从串口读取数据并实时绘制曲线图，非常好用。(VC data from the serial port to read real-time rendering curve is very useful.)

VC串口通信modbus协议源代码,测试可用。(modbus通信协议)(VC serial communication protocol source code modbus)

vc写的基于udp的串口通信简单实例 (Udp serial communication instance, a simple small program)

此程序实现了对串口输入的ADC数据和温度数据的实时曲线图显示。(This program realizes the serial input of the ADC data and temperature data in real-time graph display.)

串口监视工具。可以监视窗口的接受和发送的数据(Serial port monitoring tools. Can monitor the window to receive and send data)

485通讯接口模块的编程应用，监控显示，检测报警显示，上下值的设置输入输出的结构(485 Communications Interface Module programming applications, monitor display, alarm detection showed that the whole value of the structure of input and output settings)

VC++的MFC开发串口调试助手源代码，包括数据发送，接收，显示制式等 (VC++ of MFC development of serial debugging assistant source code, including data transmission, reception, display formats, etc.)

使用MSCOMM控件，实现两台电脑通过串口进行通信的功能。(Use MSCOMM control, to achieve two computers to communicate through the serial port function.)
