[DSP-10] New $99.00 EZ-Kit Lite (Blackfin family)

Fri, 12 Dec 2003 07:52:20 -0700

Hello Perry!

Yes, ADI has two versions of the demo software, one time limited and the
other memory limited.  I saw the $1750 price.  That's a big discount from
the original $3500 price tag.

Concerning the DSP-10 and sound card, I have created a microcontroller
adapter.  See

   http://www.tapr.org/~n7hpr/sdr/

I've mentioned it on the list a couple of times but there does not seem to
be a lot of interest.

And I agree, an updated design would be great to help design out the
obsolete parts.  What we really need is a common programming interface so
that we can program and design hardware that interworks.  See AE4JY Amateur
Station Control Protocol (ASCP) Development Project link on the page above.

73,

- Steve, N7HPR
