(Résolu) Erreur de compilation avec uno+ds1307+lcd 1602 I2C

Bonjour à tous.

Il y a longtemps que je n’ai pas jouer sur arduino. Sur une horloge ds1307et un afficheur lcd I2c, j’ai une erreur que je n’arrive pas a déterminer. Voici la ou les erreurs:

Il y a une embrouille entre LiquidCrystal_I2C et LiquidCrystal

La ligne ci-dessus crée une instance d'un afficheur ayant une interface parallèle donc supporté par LiquidCrystal

Bonjour fdufnews et mercie de m’avoir répondu.

Mais alors comment procéder? parce que là, je suis perdu. A noter que ce code n’est pas de moi, d’ailleurs j’en serais incapable.

Cordialement JC.

Pour un afficheur LCD I2C, la déclaration doit se présenter ainsi
LiquidCrystal_I2C(uint8_t lcd_Addr,uint8_t lcd_cols,uint8_t lcd_rows);

Donc dans ton cas tu devrais avoir
`LiquidCrystal_I2C(I2C_ADDR, 16, 2);

Si j'en crois la librarie, begin() n'est pas nécessaire mais par contre il faut appeler lcd.init() dans le setup() avant de faire afficher quoi que ce soit.
Le plus simple serait de regarder les exemples installés avec la librairie que tu utilises.

un grand merci mais maintenant j’ai une autre erreur.

setBacklight_Pin() n'existe pas dans cette librairie, il suffit de virer la ligne. Sur l'afficheur I2C, il n'y a pas de broche dédiée au rétro-éclairage car c'est géré par le composant qui fait l'interface entre le bus I2C et l'afficheur.

Bonjour fdufnews.

Un grand merci pour le coup de main, ça fonctionne maintenant. J’ai bien compris le fonctionnement de la librairie. A noter qu’il n’y a pas de dérive de l’horloge depuis hier.

Cordialement JC.

LA DS1307 n'est pas très fiable dans le temps mais pas à ce point. Tu devrais noter une dérive de quelques secondes au bout de 3-4 jours sans doute.
