Hi Pete

Got any pics of your controller ;-)

Havent  had a chance to play with my 18F  chips ......is it a big step up
from the 16F series ??

Dave Mc Laughlin used Atmel /canbus  for his heating controller.....

How many devices have you on your canbus network....??

I believe there doesnt have to be a master on a canbus system ...?? and the
canbus chips  ensure all message get onto the bus ???
