I2c Overview [TOP]
Multiple masters can control the same slave, and multiple slaves can reside on the same bus.
Data is sent in 8-bit bytes, most significant bit first, with each byte followed by an ACK/NACK bit. I2C Overview
Each slave device has a unique 7-bit (or 10-bit) address, eliminating the need for complex Chip Select (CS) lines used in SPI. Multiple masters can control the same slave, and
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
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).
The master pulls the SDA line low while SCL remains high.
SDA and SCL are connected to a voltage source via pull-up resistors, allowing devices to pull the lines low without creating short circuits.
