Webb5 maj 2016 · After sending the slave address: when the I2C master sends the address of the slave to talk to (including the read/write bit), a slave which recognizes its address sends an ACK. This tells the master that the slave it is trying to reach is actually on the bus. If no slave devices recognize the address, the result is a NACK. Webb11 jan. 2015 · I2C PROTOCOL: This protocol uses 2 bidirectional open drain pins SDA and SCK for data communication.
