CAN

Kommunikation über das CAN-Protokoll

Controller Area Network (CAN) ist ein robustes Kommunikationsprotokoll, das die Kommunikation zwischen mehreren Geräten ermöglicht. Sie können die Funktionen von CAN nutzen, um robuste und zuverlässige CAN-basierte Kommunikationssysteme effizient zu entwerfen und zu implementieren.
