Bonjour, je suis étudiant en BTS SN et pour mon projet je dois réaliser un didacticiel à partir d'un Arduino Mega 2560, de 3 boutons poussoir et d'un afficheur graphique TFT2.8".

J'ai déjà réalisé le code sauf que mes messages (mes println) se superposent sur l'écran et mes boutons ne font pas changer mes pages.

Je vous mets le code afin que vous compreniez plus en détail ma demande:

Code :

Si vous avez des solutions à m'apporter ou des questions plus précise, ça serait sympa.

Merci à bientôt.
