1. Are you running an example program that was provided by eDSP??
If not, I suggest that you run and understand the examples before you
try to do anything else.

2. Did you install the 2 pin power connector on your DSK??
If yes, does the LED blink with the operating mode??

3. There are 2 ways to perform your output - 'push' the output from
the DSP [DSP Services] or 'pull' the output from the PC [Host
Services]. The documentation looks like DSP Services [what it sounds
like you are planning to use] will be limited to about 4 K chars/sec.

BTW, since I have had a few questions on eDSP and did some
investigation. The owner of the company is very much a 'good guy' and
has been very active in making DSPs more usable to students since the
6211 DSK came out several years ago. Judging from the providing
documentation, I have great confidence that the provided software will
work well for its intended use. I mention this because there some
products out there that provide very little useful
software/documentation.
[This reflects my personal opinion and I am not affiliated with eDSP].
