从串行端口读取数据 [ ^ ]

从中，您将获得输入/输出数据并将其显示为图形.

谢谢.

See My answer at


Reading Data from Serial Port[^]

From it you will get the data Input/Output and show it to graph.

Thanks.

就这样.

这闻起来很像您的作业，所以没有代码！

您将需要:
SerialPort类实例:处理已接收数据 [ ^ ]事件和从传感器格式转换为实际温度.
存放它的地方:我建议使用列表类 [

So do it.

This smells strongly of your homework, so no code!

You will need:
A SerialPort class instance: handle the DataReceived[^] event and convert from sensor format to actual temperature.
Somewhere to store it: I would suggest a List class[^] - what type you put in the list depends on what kind of temperatures you receive from the sensor. I would suggest your own class, so that you can timestamp each temperature, to help with charting them.
A Chart control to display it (MS provide one if you aren''t going to make your own - Google will help you find it.
Buttons, and code to save and load - again this will depend on what your values look like.
