bonjour je reviens vers vous une nouvelle fois pour le code de mon DFPlayer mini
après avoir chercher sur les tutos et sur le net ,même sur chatgpt, je ne trouve pas comment afficher ma piste en cours /
j'ai bien créer le void spécifique pour la lecture de la piste avec son adresse hexa trouver dans le datasheet du DFPLAYER MINI mais je pense que j'ai raté une étape .
ci joint le code
merci d'avance pour votre aide.
