I2C-bus also known as the IIC bus, the main advantage is its simplicity and effectiveness. The interface directly above the component, the I2C bus, a very small footprint, reducing board space and the number of chip pins, reducing interconnection costs. The length of the bus up to 25 feet, and able to support the maximum transfer rate of 10Kbps to 40 components. Another advantage of I2C bus is that it supports multi-master (multimastering), any of them can be sending and receiving devices can become a main bus. A master can control the signal transmission and clock frequency. Of course, at any point in time only one master. This is the code at24c02
