Code pour affichage info sur MAX7219

International Français
7

Et voilà le résultat. Voici l'utilisation :

  • Récupération des valeurs température et consommation sur le Jeedom pour affichage des informations.
  • Arrêt/Démarrage écran en fonction de la présence ou bouton
  • Intégration d'une sonde BMP280 pour remonter la valeur dans Jeedom
  • MAJ via OTA
  • Affichage de l'heure via NTPClient

Je reste bien sûr ouvert à toutes remarques/amélioration, surtout avec le niveau de novice en code.
