Evalbot I2C & Nunchuk lib

After few long evenings I created I2C library for Evalbot from Texas Instruments. I wanted use I2C module which can be connected to J0 and PJ1 pins which are perfectly accessible but I had no luck with initialization of them.

So the second try was about using another I2C module connected to pins PB2 and PB3. These pins are also on expansion connector but I don't have the other side of the connector so I soldered near the pull-up resistors and the audio codec.

Short tutorial, pictures and libraries are on the homepage
