bonjour à tous,
j'ai un problème d'interruption dans un code pour lire 5 débitmètres à effet hall sur un arduino uno et un lcd key pad.
le problème c'est que je peux lire les voie 1 et 2 qui sont sur les pin 2 et 3
mais pas les voies 3 4 5 sur les pins 11 12 13
les autres pins sont pris par le lcd.
j'ai cru voir que les pins 2 et 3 sont interrupts et pas les autres
y a t il un moyen de faire fonctionner différemment ou dois-je acheter une mega 2560 ?
