Hello, depuis tout petit j'ai toujours rêvé d'avoir un afficheur avec un gros chiffre rouge pour me dire sur quel rapport je suis... ben, j'y suis presque.
Sauf que ce fichu code arduino me fait perdre les derniers cheveux qui me restent. J'arrive à afficher les vitesses en montant et en descendant, a l'initialisation du digit ça part même sur un 0 (point mort) par contre si j'ai le malheur de vouloir descendre un rapport avant d'enclencher la 1ere, un 1 s'affiche. Alors que je souhaiterai ne pouvoir afficher la première qu'avec la première impulsion positive. Si je tripote le levier en descendant les rapports en partant du point mort, je ne voudrai avoir que le 0. Quelle ligne rajouter à ce fichu code ???? Si une âme charitable pouvait se pencher sur mon cas désespéré....
