Bonjour à tous,
voilà mon premier projet avec arduino, j'avoue que je n'y connais pas grand chose mais j'essaie de comprendre en utilisant mes notions de PHP, javascript etc.
Je suis sur un projet qui est presque terminé, c'est une sorte de répondeur qui enregistre les messages sur une carte SD. J'ai un bouton qui me permet de lire les enregistrements mais cela ne lit que le dernier.
En modifiant PlayAllRecordings à la place de PlatLastRecording j'arrive à lire tout mais cela commence par le plus ancien. Or J'aimerai lire plusieurs messages en partant du dernier pour écouter le plus récent dabord donc. Eventuellement choisir une limite par exemple les 5 ou 10 derniers, mais toujours avec le plus récent en premier de façon à écouter dabord celui que l'on vient d'enregistrer.
Donc en gros quand je décroche le combiné, j'appuie sur le bouton lecture, j'entend le message que je viens d'enregistrer, puis le précédent,, puis encore le précédent et ainsi de suite avec une limite queje pourrai remettre à 1 facilement pour n'écouter que le dernier.
J'ai suivi un tuto pour faire tout ça, donc le code n'est pas de moi. J'espère que vous allez pouvoir m'aider car cette fonctionnalité m’intéresse vraiment beaucoup.
Merci par avance à ceux qui me répondront, en espérant qu'une solution simple me permette d'y arriver
voici le code:
