Bonjour 
Voilà, je possède un Arduino nano et des MAX7219 et je recherche à faire défiler un texte.
Pour se faire, j'utilise le programme ci-joint.
Et lorsque je lance la vérification, il m'indique :
sketch_aug11b:8: error: variable or field 'scrollMessage' declared void
sketch_aug11b:8: error: 'prog_uchar' was not declared in this scope
sketch_aug11b:8: error: 'messageString' was not declared in this scope
sketch_aug11b:11: error: 'prog_uchar' does not name a type
sketch_aug11b.ino: In function 'void loop()':
sketch_aug11b:23: error: 'scrollText' was not declared in this scope
sketch_aug11b:23: error: 'scrollMessage' was not declared in this scope
sketch_aug11b.ino: At global scope:
sketch_aug11b:29: error: 'prog_uchar' does not name a type
sketch_aug11b:903: error: variable or field 'scrollMessage' declared void
sketch_aug11b:903: error: 'prog_uchar' was not declared in this scope
sketch_aug11b:903: error: 'messageString' was not declared in this scope
variable or field 'scrollMessage' declared void
Quelqu'un sait il comment résoudre ce problème?
D'avance merci
