Abstract
L'invention concerne un système comprenant une pluralité de cartes (20, 21) dont chacune comprend un capteur (12) et un processeur de commande (22, 23). Les cartes sont connectées ensemble par un bus série (24). L'une (20) des cartes agit en maître et les autres (21) en esclaves. La carte maître est adaptée à accéder aux mesures de la pluralité de cartes et à envoyer ces mesures par une connexion UART (26), à un processeur hôte (28). L'acquisition des mesures se fait selon un procédé de de synchronisation spécifique.
