Bonjour,
Je tente de faire un truc extrêmement simple avec un PIC18F458, allumer une diode, pour tester mon programme écrit sous MPLabX et compilé avec XC8.
Le PIC fonctionne, avec un ancien programme qui est dedans, mais quand je flash le PIC (avec un ICD3), et bien le PIC n'a pas l'air de réceptionner la nouveau soft, il continue sur l'ancien. MPLabX n'affiche aucun message d'erreur...
J'ai essayé de voir d’où vient le problème, mais rien... Le programme est ci dessous. J'ai oublié quelque chose d'important ? Les config sont généré avec MPLabX
