bonjour, je suis débutant j’ai un capteur meteo qui m’envoie des valeurs toutes les minutes.
j’ai un graph qui affiche ces valeurs sur 24 h.
=> je trouve que cela prend trop de place inutilement en mémoire, donc je voudrais filtrer ces valeurs à 1 toutes les 15 mn.
j’ai réalisé un exemple ci-dessous ( petit programme ) ( j’ai 3 entrées qui simulent les infos capteurs temperature que je clic toutes les 5 secondes et j’ai une entree true qui est valide toutes les 2 minutes => je voudrais valider l’info capteur qui arrive toutes les 2 minutes )
j’espère avoir été assez clair ? ? ?
merci de m’aider :
