AVR-Chat

Use this:
http://hubbard.engr.scu.edu/embedded/avr/doc/avr-libc/avr-libc-user-manual/twi_demo.html

Just compile it with AVR GCC, and that's all.  Take
into account that this example is for devices like
24C04.  If you use another device with different
addressing then you will have to modify the source
code.  Check the documentation of mcp23016 and compare
with 24C04's documentation.

Jose
