Interfacing the Microchip PIC18F Microcontroller Master Synchronous Serial Port (MSSP) to various I2C Devices

The Inter-Integrated Circuit or I2C (read as I square C) bus has been introduced in 1980 by Philips, and has become a de-facto world standard for data exchange between Microcontroller and various devices such as temperature sensor, ADC (analog to digital converter), DAC (digital to analog converter), I/O expander, EEPROM, and many more. With more than thousand different IC devices have been manufactured with an I2C-bus interface, making the understanding of the working principle of this I2C bus is an essential knowledge that has to be acquired by anyone who want to involve in the embedded world professionally or just as hobbyist.
