C'est un problème qui a déjà été rencontré, en fait toutes les cartes n'utilisent pas le même driver.
Certaines ont besoin du driver ST7789.
Si le fait de compiler le code ne vous fait pas peur, vous pouvez essayer la solution expliqué dans ce post :
https://f1atb.fr/forum_f1atb/thread-1133...l#pid10015
Cela a marché pour des utilisateurs mais pas pour d'autres (pas de tactile) donc même parmi les cartes qui ont besoin du driver ST7789 il y a encore des différences concernant le tactile.
bonjour, de mon coté; après le téléversement j'ai toujours un écran noir, je pense que mon pb viens de la librairie lovyan comme pour les autres utilisateurs, mais le fichier ecran.h que j'ai testé aussi semble ne pas etre compatible non plus.
je précise que j'ai fait des modifs dans mon User_Setup.h du dossier TFT_eSPI et que depuis j'ai ce fichier test qui me donne bien de l'affichage :
/*
Example animated analogue meters using a ILI9341 TFT LCD screen
Needs Font 2 (also Font 4 if using large scale label)
Make sure all the display driver and pin comnenctions are correct by
editting the User_Setup.h file in the TFT_eSPI library folder.
