Hi
1st off wow! that code is tiny!! 
and i would never of thought of setting it up that way.
i was just wondering if you could possibly guide my through the code a little. This is my first ever C/C++ coding and what I've managed to do so far has been a mash up between reading the data sheet, internet searches and the forums on here.
What im trying get my head round is how each device is initiated :~.
thanks again, and sorry im such a n00b 
matt
