Bonjour,
j'ai besoin d'une aide pour l'affichage sur le moniteur série de mon Arduino des informations reçu de la carte émettrice dans le protocole I2C
je reçois bien les informations avec sur RX de l'Arduino récepteur mais sur le moniteur série l'information est découpée en ce sens qu'elle s'affiche de manière verticale au lieu d'horizontale et j'aimerai une aide pour résoudre ce problème.
ci joint les codes
