CAN

Comunicazione utilizzando il protocollo CAN

Controller Area Network (CAN) è un protocollo di comunicazione robusto che abilita la comunicazione tra più dispositivi. È possibile sfruttare le capacità del CAN per progettare e implementare in modo efficiente sistemi di comunicazione basati su CAN robusti e affidabili.
