In this instructable you will learn :
how to receive data from your arduino
how to plot them on a graph
To do this I use Qt (say cute) which I already presented in my former instructable :
Control your arduino from your PC with the Qt Gui
To start to write your programs you will need to:
install Qt (sounds obvious ;) ) : https://qt.nokia.com/products/
install the additional library to read the port com : see my former instructable
install the additional library to put graphs in your programs : see the next step.
PS : As you probably notice it, I am not a native English speaker. I would be please if you can correct me.
Step 1: Installation of QWT
I assume that you have already installed Qt, and you have basic skills in programming in C/C++.
First you need to get qwt from source-forge : http://sourceforge.net/projects/qwt/
Then you extract the files.
Here comes the tricky part. The files you downloaded are not compiled.
So you must compiled them. To do so you must start the Qt prompt console.
You can find it on Windows in :
Qt 4.7.3 for Desktop (MinGW)
Then send the command that are on picture 2.
Congratulation, you perfectly compiled the library!
