Bonjour à tous !
Dans mon projet réalisé sous AVR32, je souhaite réaliser deux type de communication sur ma carte atmel AT32UC3A0512.
La première est la communication série et la seconde une communication telnet.
Séparément elle fonctionne mais lorsque je relis les 2 dans mon main, je ne peut communiquer qu'avec une d'entre elle (celle situé en premier)
Voici le code.
