oui
Parce que dans ce cas là, juste écrire à 0x90130018 marche, je viens de tester sur ma CX II-T CAS
c'est bien ce que j'ai essaye de faire pourtant.
Mais c'est peut-etre le lcd controller qui pose probleme. Ce que je ne comprends pas c'est que le code suivant passait avec le precedent ndless mais pas avec celui-ci
