Bonjour Tout le monde, 
je suis en train de programmer une matrice 8x8 verte avec un MAX7219.
Cependant après que mon programme a boucler une fois, ma matrice n'affiche plus rien ... =(
et si je reset ma mega, c'est pareil ... =(
Pouvez vous m'aider ? 
Merci.

Hello Everyone,
I'm trying to program a 8x8 green matrix with a MAX7219.
However, after my program loop once, my matrix does not show anything ... =(
and if I reset my mega, it's the same ... =(
Can you help me?
Thank you.
