CAN Protocol - OverviewCAN Protocol - Overview

CAN protocol , is a serial communication protocol widely used in the vehicle industry, due to it’s high reliability.

The CAN-Bus consists of several nodes connected to a single serial Bus.

Flexible : adding new components is simple.

Collision avoidance : only one node transmits, all other listen.

Message ID, not component ID.

Smart Error management.
