I2C Communication Protocol Q&A Collection for Self-Assessment -- Part 2

1. What is the basic principle of I2C communication?A: I2C adopts a master-slave communication mechanism. The master device initiates and controls the communication, while the slave device responds to the master’s requests. 2. What are the key features of I2C communication?A: Supports multi-master and multi-slave architecture; requires only two communication lines; supports different transmission rates. … Read more

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
