Bonjour,

Je devais faire un Bargraph basique sous LabWindows CVI (sans trop d'explications données).
D'après ce que j'ai compris j'ai fais un truc qui me donne ça:


J'ai donc fait un switch sur l'état de 'BUTTON1' (le potentiomètre); et en fonction de cet état je décris l'état de chaque LED (0 ou 1).... seulement ça me parait un peu barbare comme méthode.

Ma question est donc: Est-ce qu'il y a moyen de simplifier tout ça... ?

Voici le code de la partie en question:
Code : Sélectionner tout - Visualiser dans une fenêtre à part
