  • Bonjour,

    mon application lit des données issu du USB, et fait déplacer les blocks d'une Tetris selon ces donnée.

    le problème que la valeur data2 ne se change pas durant l’exécution du programme, elle prend uniquement la première valeur lit de l'USB.

    j'ai essayé plusieurs méthodes, c'est pourquoi vous allez trouver que mon code est un peu gênant!

    SVP aidez moi :/

    voici le code.
