The master releases the SDA line to high while SCL is high, signaling the end of transmission. Advantages and Limitations Understanding I2C
Each slave device has a unique 7-bit (or 10-bit) address, eliminating the need for complex Chip Select (CS) lines used in SPI. 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 releases the SDA line to high
The master sends the 7-bit unique address of the target slave, followed by a R/W bit (0 for write, 1 for read). 1 for read).
