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 )

串口通信，采用CRC16 算法，用mscomm控件实现对chp500电源的信息采集，可以设置电源的电压和频率，word文件的是通讯协议，上位机发送和下位机返回，串口通讯看懂了通讯协议就没什么问题的啦。(Serial communication using the CRC16 algorithm, mscomm realize chp500 power control information collection, you can set the voltage and frequency, word document is the communication protocol, host computer to send and return lower machine, serial communication protocol is very important to you)

一个多线程串口编程的test，简单而实用，适合工业控制(A multi-threaded programming serial port test, easy and practical for industrial control)

说明：  串口通信，对串口发出的数据进行读取和处理，进行检测(Serial communication, read and process the data sent by the serial port, and detect it.)

串口调试程序源代码，本例作为学习串口编程具有很好的参照作用。(Serial debugger source code, in this case as a learning serial programming with a good reference to the role.)

this is visual c++ 6 project it is a Serial port excerszier software

通过调用API函数实时采集来自串口的数据,并将数据实时显示在界面中(function: sample data come from serio port and display information in form)

使用vc++开发的云台镜头控制系统，主要通过串口实现控制，已编译通过，可学习使用(PTZ camera control system)

说明：  比较实用的串口编程基本知识和实例，没时间整理，下了自己正吧(Serial programming of the basic knowledge and examples)
