Has anybody tried to write a CAN communication layer on a small PIC?
The planned CAN controller is much too big for simple applications...

I think that CAN spec is a bit too resource greedy to work well on
little PICs, perhaps you could try a small Alterra part using a CAN
design note (probably in their CDROM)
, these are a sophisticated programable logic part.

The obivious restriction would that it would have to run pretty slowly. I
think 50 pkts/sec should be easily doable on a '84. This corresponds to
5000kbits/sec (assuming 100bit packets - all 8 bytes full). I would
probably use RS485 as a physical layer (with my data out connected to the
control pin of the transciever).
So, I think implementing the protocol is doable, just so long as you don't
want to connect it to real CAN devices.
