je veux dessiner un graphe en temps réal en recevant des données a partir le PORT USB..
est ce que quelqu'un a une idée ?

merci d'avance


I used Google translate to translate your question to English, and it seems you want to draw a graph and get the data from a USB port. For this scenario, you may want to check the existing solutions to the similar question.

You should write in English here...

For any serious real time graph, you should consider using existing components that fit your need...

For simple case regular chart might do or you might draw yourself on screen.
