résumé
le TP de la semaine de la fabacademy consiste à se familiariser avec la programmation de microcontroleurs et processeurs.
je vais commencer par programmer les deux circuits que j'ai réalisé : le FabISP et le helloWorld
premiers pas
La première étape est de finir mon travail en retard sur le fabISP : comme j'attendais l'arrivée des composants, je n'ai pas eu le temps de programmer le circuit à temps. De plus je ne comprenais pas bien la logique d'alimentation du circuit : je croyais que le programmateur alimentait la puce cible alors qu'il fallait qu'elle le soit séparément...
