Les sorties num\u00e9riques sont les p\u00e9riph\u00e9riques les plus simples utilis\u00e9s pour commander d’autres appareils. Sur les appareils ESP32, ils peuvent \u00e9mettre un signal haut de 3,3 V qui correspond g\u00e9n\u00e9ralement \u00e0 l’\u00e9tat de marche, ainsi qu’un signal bas oppos\u00e9 de 0 V qui est g\u00e9n\u00e9ralement interpr\u00e9t\u00e9 comme un \u00e9tat d’arr\u00eat. Ce p\u00e9riph\u00e9rique peut \u00eatre connect\u00e9 \u00e0 des transistors, des MOSFET, des relais et d’autres dispositifs \u00e9lectriques qui effectuent une action en fonction d’une tension d’entr\u00e9e. Le signal de 3,3 V peut \u00eatre d\u00e9plac\u00e9 vers une tension de 5 V, 12 V ou plus \u00e0 l’aide d’un d\u00e9caleur de niveau si l’appareil \u00e9lectrique \u00e0 commander fonctionne \u00e0 une tension plus \u00e9lev\u00e9e.<\/p>\n

Configuration des sorties num\u00e9riques<\/h2>\n

Les principaux aspects \u00e0 configurer dans les sorties num\u00e9riques sont la broche \u00e0 utiliser et le type de point de donn\u00e9es. La plupart des broches de l’ESP32 peuvent \u00eatre utilis\u00e9es comme broches de sortie. Les exceptions sont les broches les plus hautes, 34 \u00e0 39, ainsi que les broches inf\u00e9rieures \u00e0 16 qui peuvent \u00eatre utilis\u00e9es mais qui peuvent \u00e9mettre des signaux au d\u00e9marrage. Pour plus de d\u00e9tails, consultez la r\u00e9f\u00e9rence des broches de l’ESP32.<\/a> Le type de point de donn\u00e9es aide \u00e0 d\u00e9finir les t\u00e2ches du contr\u00f4leur de valeurs de consigne, ce qui leur donne un contexte pour l’appareil connect\u00e9, par exemple l’unit\u00e9 qu’il attend.<\/p>\n

Par d\u00e9faut, un point de donn\u00e9es est enregistr\u00e9 \u00e0 chaque fois que la valeur est d\u00e9finie. Ces points de donn\u00e9es peuvent ensuite \u00eatre utilis\u00e9s dans des tableaux de bord pour montrer les changements d’\u00e9tat des appareils connect\u00e9s. Ce comportement peut \u00eatre d\u00e9sactiv\u00e9 dans les t\u00e2ches du contr\u00f4leur de valeurs de consigne.<\/p>\n

Dans la section avanc\u00e9e, l’\u00e9tat initial de la sortie num\u00e9rique peut \u00eatre r\u00e9gl\u00e9 sur haut ou bas. Par d\u00e9faut, la sortie n’est pas d\u00e9finie. En outre, la sortie num\u00e9rique peut \u00e9galement \u00eatre configur\u00e9e comme active basse. Cela signifie que s’il re\u00e7oit un 1, la sortie est r\u00e9gl\u00e9e sur 0V. Inversement, une valeur de 0 fixe la sortie \u00e0 3,3V. Cela simplifie la logique dans le reste du syst\u00e8me qui s’attend \u00e0 ce qu’un appareil soit allum\u00e9 lorsqu’il envoie un 1, m\u00eame si l’appareil s’attend \u00e0 l’inverse.<\/p>\n

Test des sorties num\u00e9riques<\/h2>\n

Il est possible de tester les p\u00e9riph\u00e9riques de sortie num\u00e9rique directement \u00e0 partir de la page de configuration sans avoir \u00e0 lancer manuellement une t\u00e2che du contr\u00f4leur. Les boutons de mise en marche<\/em> et d’arr\u00eat<\/em> commandent la mise en marche et l’arr\u00eat du p\u00e9riph\u00e9rique. Assurez-vous que les param\u00e8tres ont \u00e9t\u00e9 sauvegard\u00e9s, sinon l’ancienne configuration sera utilis\u00e9e.<\/p>\n
