I2c Overview Instant

SDA and SCL are connected to a voltage source via pull-up resistors, allowing devices to pull the lines low without creating short circuits.

I2C communication is master-controlled. The master initiates, manages, and terminates communication, generating the clock signal. I2C Overview

Data is sent in 8-bit bytes, most significant bit first, with each byte followed by an ACK/NACK bit. SDA and SCL are connected to a voltage

The slave device with the matching address responds with an Acknowledge (ACK) bit (low), signaling it is ready, or a Not Acknowledge (NACK) bit (high). and terminates communication

Each slave device has a unique 7-bit (or 10-bit) address, eliminating the need for complex Chip Select (CS) lines used in SPI.
