I2c Overview | FAST | VERSION |

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

Data is sent in 8-bit bytes, most significant bit first, with each byte followed by an ACK/NACK bit. I2C Overview

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 releases the SDA line to high while SCL is high, signaling the end of transmission. Advantages and Limitations Understanding I2C 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.
