Bonjour,
Difficulté à la consigne: “Read the accelerometer and magnetometer values every 500ms in an endless loop in the thread handler function”.
Je n’arrive pas à lire les deux sensors (problème dans la gestion des Threads et Loop).
Voici mon main.c et je n’obtiens dans le terminal que le print des données du sensor 1 (Pressure/temp).

N’ayant pas de base en programmation, je suis un peu perdu sur ce point.
J’ai essayé de joué avec les valeurs de priorisations des threads… pas d’amélioration.
Merci pour vos conseils !
