I've got enough working that I can enter commands in a test app on the PC,
which sends commands over the USB, which causes the host CAN controller to
send a frame, which is received by another board, which causes it to wiggle
some I/O lines.  Eventually there will be a family of I/O boards, but for
now there is a single one that has some digital inputs and outputs.  The
command set is just enough to prove communication is working.  The CAN
protocol will eventually be very different, which is the part I'm working on
now.  You caught me rather in the middle of getting the whole system working
the way I intend.

I was planning on making the code available eventually, but you can see a
snapshot by first installing my PIC development environment, then
http://www.embedinc.com/ioext/install_ioext.exe.  The source code will be in
the SOURCE > IOEXT directory within the software installation directory.

Again, this is work in progress and isn't pretending to be a finished
anything at this point.  I may be willing to answer a few questions, but
this is definitely not supported.  If you want to follow the code, you'll
also have to learn my preprocessor first.

The IO1 board that the IO1C firmware runs on needs a revision, so I'm not
going to release a schematic at this point.  Also, ignore the P1 connector
on the HCAN0 board.  I don't even want to explain what that's about.
