How to use I2C-bus on the Atmel AVR Microcontroller
Wednesday February 04, 2009 by rwb, under Microcontroller.
I2C (read as I Squared C) bus first introduced by Philips in 1980, because of its simplicity and flexibility the I2C bus has become one of the most important microcontroller bus system used for interfacing various IC-devices with the microcontroller. The I2C bus use only 2 bidirectional data lines for communicating with the microcontroller and the I2C protocol specification can support up to 128 devices attached to the same bus. Read more »
