As the "keeper" of DirectDSP software, I can say this:

1) It does not support C6713 DSK board because the combined USB-JTAG interface is
slow, around 20-30 kbyte/sec. Neither USB or JTAG by itself should be that slow, but
it's something in the Spectrum Digital implementation. I'm sure they could have made
it faster, but as you say, that is not TI's purpose in making inexpensive DSK boards
that provide both showcase and reference design for their chips.

2) If someone on the group can make an HPI daughtercard for the DSK board and show
basic HPI register-level connectivity from a simple C program, then we can port the
parallel port driver in DirectDSP to it. Such a daughtercard would look something
like this: __ HPI-PP daughtercard

DirectDSP has both WinXP and Linux drivers, PP and PCI. Basically any time the HPI
is accessible.

Interesting idea Jeff -
 
About the mechanical design - I don't know how expensive the Samtec connectors are.  Would it make sense to make a mechanically robust board that just does a 'pass through' on the other two connectors??
 
FYI - although this is a pretty simple design, I would be willing to offer my assistance/opinion if anyone is interested in taking on such a board.

Yes I thought about that... but I'm worried that even the bit of extra signal
distance might throw off some of the daughtercards out there. A product like
HPI-to-PP interface for DSK boards would have its share of tech support anyway, and
adding to it in any way would not be good.

I think the basic approach should be to "jack in" on the HPI connector with minimal
interference in anyone else's virtual reality :-)

Jeff and others

Try contacting educational DSP, LLC (www.educationaldsp.com).
They've got a HPI daughtercard which gives the functionality you
described. It was demonstrated at the TI Developers conference two
weeks ago. I didn't see the product on their web site yet.

We have an approach called Live Data Exchange which works with the
DSK over a standard RS-232 port. We have a Daughter card which can
be purchased which includes an RS-232 (our IDE Daughter Card). On
the PC side, LDX comes with an ActiveX server so that any windows
client can have access to the DSP target device. (see our website:
http://www.appliedsignalprocessing.com/lde.htm). This interface will
let you download new code to the DSK as well as peek/poke your target
DSP variables by name.

Hope this helps

Shawn-

Thanks for this heads-up. Educational DSP is, as far as I can tell, organized and
operated by Dr. Mike Morrow at Univ Wisconsin @ Madison. He teaches DSP and
microprocessor classes in the ECE department.

The odd thing is he has no posts on comp.dsp, here, or otherwise... must be flying
under the radar. But he knows DSP well enough and long enough to create C3x items --
and that's a ways back. A page with a DSK software summary and some screen captures
is here:

http://eceserv0.ece.wisc.edu/~morrow/software/

I'll send him a mail and find out about the C6713 DSK HPI card.

I have used one of his *free* educational software product called
windsk for c6711 , which is quite handy for testing the board for
confidence if nothing else. It can load .out files and execute them
without CCS but no more.It also few cool pre-loaded audio effects like
echo,karoke,equalizer etc...Good stuff.
