Understanding I2C Device Addressing for 24LC04

Description I2C supports N-2-N on the bus, so addresses are needed to distinguish devices. A complete transmission always starts with a START signal followed by the device address and the read/write flag. Device Address So how do we view and define the device address? The device address corresponds to the first BYTE’s BIT7-BIT1, with BIT … Read more
