In-Depth Analysis of CAN Bus Working Principles

The CAN bus, as a core communication protocol in the automotive and industrial fields, achieves high-reliability multi-node communication through differential signaling and non-destructive arbitration. Its physical layer uses CAN_H and CAN_L to transmit differential signals over a two-wire system, distinguishing between dominant (logic 0) and recessive (logic 1) states through voltage differences. Coupled with 120Ω … Read more
