Samuel,

I'm interested in this too, mostly SAE J 1939.  I'd like to share with
you, please let me know (offline if you choose) what you decide to work
with, it would be nice to swap notes.  If I find anything useful, I'll
pass it on to you.


SOFTWARE:

I've been looking for some CANopen stuff to get me started on a network
protocol layer, have you found any links that give (at least) function
headers to supply in order to be conformant?  I have not found more than
some discriptive academic papers and the like.  Some interesting one's,
but not what I need.  I'm looking for an outline of a "minimal spec" in
the form of function headers and description of basic behavior.

HARDWARE:

I've seen a MCHP development board based upon the MCP250XX chip.  Do
you, or anyone here know if this is a good deal?  It is about $169 here,
I think it comes with CAN bus sniffer / chip programmer too.  I'm using
the free C18 compiler.  This would be a nice addition to my PICDEM2+,
and fairly cheap to get "online" as it were.

Can this (the MCP250XX series chip) be made to work with SAE 1959?  Or
is the behavior strictly MCHP specific?


RHETORICAL:

Why can't this information be free?.....I'd like to use the standard,
but $500 or 500 euro is too much to spend for a book of regulations?


Good luck Samuel.
