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 )

串口通信处理的多个线程需要协调运行，一个线程必须等待另一线程结束才能开始，在处理一个线程的同时必须把其余待处理的线程挂起等待，以减少其余待处理线程对CPU的资源占用，正处理的线程一旦处理结束则通过线程间的通信发出信号来击活被挂起的线程中的一个线程进入处理。(Serial communication processing necessary to coordinate multiple threads running, a thread must wait until the end of the beginning of another thread in a thread at the same time deal with the need to deal with the rest of the thread to be suspended waiting for in order to reduce the remaining lines to be processed way of CPU resources occupation, is the thread once the deal by the end of treatment inter-thread communication signal to hit live thread was hang a thread into the handle.)
