Inter IC Communication:-
Inter IC Communication bus, often abbreviated as I2C bus, is a multi-master bi directional 2 wire serial bus for Inter IC communication, developed by Philips Semiconductor. The I2C bus consists of only two lines; one is called SDA (Serial Data line) carries the data bits and the other is called SCL (Serial Clock Line) is used as a clock signal. The messages sent over the I2C bus contain addresses to define which device should reply to them. All I2C-bus compatible devices incorporate an on-chip interface which allows them to communicate directly with each other via the I2C-bus. This design concept solves the many interfacing problems encountered when designing digital control circuits.
Before the introduction of I2C bus method, the method that was used for inter-IC communication was via a parallel 8 bit wide bus. This bus structure, which is also used to connect memory and peripherals to CPUs, requires apart from eight data lines for the data transfer,......
