Bonjour à tous,

J'essai de bidouiller avec STCubeIde pour faire clignoter la led intégrée sur PA5 avec les interruptions. Lorsque je complile le programme , j'ai une erreur de déclaration du TIMER 2;

Voilà le code et en dessous le rapport d'erreur... j'ai beau fouiller , je ne sais pas pourquoi ? C'est la ligne soulignée qui pose problème...
