Thanks.

It sounds like I posted my question at just about exactly the right time.=
=A0 I'll take a look at the current source code, but I don't know how much =
it'll mean to me.

What I AM very much looking forward to is following the progress of your pr=
oject and perhaps being able to benefit very much from it as it matures.

Thanks again!

BTW... If you came up with GP USB-CAN adapter at a $50 or $75 price-point I=
 bet it'd sell like hotcakes!!

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.=A0 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.=A0 The
command set is just enough to prove communication is working.=A0 The CAN
protocol will eventually be very different, which is the part I'm working on
now.=A0 You caught me rather in the middle of getting the whole system work=
ing
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.=A0 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.=A0 I may be willing to answer a few questions, but
this is definitely not supported.=A0 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.=A0 Also, ignore the P1 connector
on the HCAN0 board.=A0 I don't even want to explain what that's about.
