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

Fri, 12 Dec 2003 10:06:57 -0600

I've looked at your project before (in fact, I offered to build the GUI, you
may recall, if you could get the soundcard DSP functions into a DLL).  A
real worthy effort to extend the DSP-10!  One suggestion for your "glue"
logic, use a USB communication interface.  See
http://www.delcom-eng.com/products_USBIO.asp#USBIO for a $8 USB solution.
With an I/O expander chip and their 16 I/O line chip, it might be possible
to have all the "glue" logic you need.
The other interface choice, as pointed out on the ASCP site, is Ethernet.
If you went the "next" step and specified TCP/IP and VoIP protocols, it
would be possible to have a "virtual" transceiver over the Internet.  It
would be nice to throw out a few calls from work (during your breaks, of
course!  ;-> ).
