Abstract

Excitation et lecture d'un réseau d'oscillateurs LC La présente description concerne un système électronique (5) comprenant des oscillateurs LC (LCA, LCB, LCT) connectés à des circuits d'entrée/sortie à usage général correspondants (GPIO1, GPIO2, GPIO3). Le système (5) comprend un circuit de commande (CTRL) qui, lorsqu'il est activé par un microcontrôleur (µC) du système (5), commande l'excitation et la lecture des oscillateurs LC par l'intermédiaire des circuits d'entrée/sortie à usage général. Le système (5) comprend en outre un circuit (PM) pour éteindre le microcontrôleur (µC) après l'activation du circuit de commande (CTRL) par le microcontrôleur (µC). Figure pour l'abrégé : Fig. 1
