Bonjour,
je n’arrive pas a faire fonctionner l’écran intégré de mon ESP32 avec esphome
j’ai recu en test l’esp32 suivant : https://www.amazon.fr/diymore-ESP32-ESP-WROOM-32-OLED/dp/B0DK399Y9Q?ref_=ast_sto_dp&th=1
je l’ai intégré sans souci via esp home et fais qque test tout va bien, je le retrouve dans home assistant.
mon probleme, c’est quer je n’arive pas a faire fonctionner l’écran, alors que le programme de test préchargé (et que je n’ai plus bien sur:/ ) affichait bien une image en couleur.
Comme je débute en esp home j’ai peu etre loupé qque chose?
touours est il que je me tape les mots doux suivants dans les logs
