}Quand je debug en pas à pas, une led connectée sur le port B pin 4 s'allume puis s'éteint et si je laisse aller le programme elle s'allume moins lumineuse puisqu'il n'y a pas de délai. Je n'ai pas trouvé de délai qui fonctionne mais c'est un autre problème.
Si je clique "make and program device main project" (j'utilise mplab) la comilation se fait bien et la programmation du pic aussi mais j'ai uniquement des chose bizarre qui se passe (soit led est éteinte soit légèrement allumé, soit elle s'allume quand j'approche mes doigts à quelques centimètres !).
Je ne sais pas ce qui n'ai pas bon, peut être les réglages pour l'oscillateur car je n'ai pas tout compris.
Merci d'avance.
