Principles and Programming Implementation of I2C Communication in Embedded Technology (Temperature and Humidity Sensor)
1. Detailed Explanation of I2C Communication Principles 1. Hardware Structure and Physical Layer Bus Topology: The I2C bus is a multi-master/slave structure that supports multiple master and slave devices sharing the bus. SCL (Clock Line) and SDA (Data Line) are both open-drain outputs and require external pull-up resistors (typical value: 4.7kΩ, specific values should be … Read more
