The master sends the 7-bit unique address of the target slave, followed by a R/W bit (0 for write, 1 for read).
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). 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. The master sends the 7-bit unique address of
The master releases the SDA line to high while SCL is high, signaling the end of transmission. Advantages and Limitations Understanding I2C The master releases the SDA line to high
Multiple masters can control the same slave, and multiple slaves can reside on the same bus.
The master pulls the SDA line low while SCL remains high.
I2C communication is master-controlled. The master initiates, manages, and terminates communication, generating the clock signal.
