Try looking at these URL's maybe there is something here that can be useful.  Try all of the links, these should provide you with hours of learning and reading.  Some URL's may apply more than others, I did a random search... and I think atleast on or two will have what you are looking for.

There appears to be a fair amount of interest in using CAN on the PIC18's.
If there are no objections, I am open to collecting a few E-Mail addresses
of persons who might want to exchange ideas, PIC code, and projects offlist.

I am committed to continuing my own work, and would be willing to share with
others as working code becomes available. I am currently working with some
folks at MChip also to refine some of the Maestro code.

I don't claim to be an expert, but I would be happy to try and manage some kind
of informal offlist group to exchange ideas and information.

If anyone is interested in the same, please write me at lylehaze@bellsouth.net

If this suggestion is not in the best interest of the PICList as a whole, please
reply onlist and I'll be happy to comply with whatever decision is reached.

Lyle
