Bonjour à tous, débutant en Arduino je souhait faire comme 2 boucles pour traiter deux informations en même temps sans fin...
Exemple :
J'ai une bouche qui fait un chenillard va et vient (déjà fait) mais j'aimerais que les yeux clignotent tout le temps et en même temps que le chenillard.
Merci.
Voilà, voilà :
Tu remplaces SDL_GetTicks par millis() et le tour est joué... bon d'accord y un peu de taf, mais c'est comme ça au début pour comprendre ce que l'on fait 
Sinon il y a une lib que s'appele Protothreads pour l'arduino.
Il y a eu une discussion dessus à cette adresse :http://arduino.cc/pipermail/developers_arduino.cc/2009-January/000456.html
La lib est dispo ici : Garn, Krea- & Hobbybutik online - Køb garn og tilbehør billigt her
Je précise que je n'ai pas testé.
J'ai utilisé ProtoThread mais int led2 et int led1 restent allumés tout le temps et les 2 leds spéciales s'allument qu'à la fin du va et vient.
