Bonjour,
Très étrange ce qui m'arrive ce midi.
Après plusieurs heures de fonctionnement parfait, je modifie un peu le code et la compilation reste bloquée sans aucun message d'erreur.
Je charge un programme exemple RAS tout passe 
Je vous propose mon programme

Pour ce qui est des branchements, tout fonctionnait avant, je pense qu'il s'agit là d'un soucis logiciel.
Merci pour votre aide
Seul message dans la fenêtre compilation :
_"Les options de compilation ont été modifiées, tout sera recompilé"*_
Et il tourne en boucle
