I'm sure this is somewhere on the web but I can't find it. How do I
load the Chapter 10 and 11 code into the DSPx/KDSP10 and then how do I
execute it? NOT DSP-10, just FIR filters, etc.

Thanks

Hi Tom,

The page you are probably looking for is KK7P's DSPx page:
http://www.kk7p.com/dsp.html

This includes a link to Roger Hayward's Windows loader that can be used to
get the programs into the DSPx. If you want to load and run from DOS, I
recommend Dwight Elvey's EZLD for small programs:
http://www.proaxis.com/~boblark/ezld.zip
Both of these load the program to PM and it will stay there as long as the
power stays on.

Finally, if you end up with a large program, such as the DSP-10 , it is
most handy to load it permanently to flash and run at startup. This is
more complicated, but works well, and I am happy to say has no reported
bugs. I use this exclusively with the DSPx now. It is linked from
http://www.proaxis.com/~boblark/dsp10.htm
Look about half way down the page, below the picture of the DSPx.

And, there must be several more ways to do the load and go! Maybe someone
has other suggestions.

Good luck with your experiments, and let us know how it goes!

Thanks for the info Bob.
I got the Windows loader to work with my DSPx/KDSP10. I am new to
embedded programming; I'm just doing the FIR filters etc in Chap 10
of EMRFD. If I may, let me ask you a question. If I run want my rig
(TS940) audio thru the KDSP to see the effects of different filters,
which audio signal do I grab? Right now I'm just running the
headphone output to the KDSP input and listening to the KDSP audio
output with headphones.

Thanks,
Tom N4WBS


And is there any way to grab the input and output signals to plot in
Matlab, etc?

That should work fine.

Hi Lyle,
Now I'm ready to write my own code. What environment do you suggest
for an assembler/debugger to generate .exe files?

Using the Analog Devices tools, a DOS computer is the first choice. I
outline how to set the tool sup under Windows XP here <

Windows XP Environment Variables"

Hi Lyle,

With regard to DOSBox as mentioned on your site, I've found that it
solved a problem with DOS programs that run full screen under Windows
XP, including Wes, W7ZOI's IRFD programs. Wes has a page on his site
about this, specifically in doing printscreens. The version that I
used to run Wes's programs, and also some of the DOS programs on the
RF Cafe site, was version 0.63 (your site mentions ver. 0.61).
Unfortunately, my attempts to use the latest version of DOSBox, 0.65,
for these programs have been unsuccessful.

The good news is that versi
