Brian,

I had a (very) quick look at it, and it looks fairly complex to me, 
lots of decoding and stuff. I'm a very basic c programmer, and that 
looks above my skill level, plus it appears you need an RS485 chip. 
Wouldn't it be easier to utilise a 2 wire interface instead? I'm 
currently looking at the mega64, and it has the module onboard, but 
it appears to allow multi-masters, and only needs the two pull-ups 
on the SDA & SCL lines. I realise that it'd be a pain in the butt on 
older chips (I've played with 8535s), but I think it may be simpler 
to implement.

In your opinion, would it be easier/more efficient to go for TWI or 
for ROBIN?
