Hello,

I am an intern for a lab, and I recently installed P25M from Innovative
Integration on a pc.
I was told to use Octave, which I found easily.
My next step, however, is this:
"Get a sample code for data logging using DSP"

I AM STARTING COMPLETELY FROM SCRACTH.
PLEASE HELP ME.

Answers such as "read a book first," "read basics first" will not help
because I was told to "get a sample code," not learn about DSP.

If anyone could help me, it would be really really appreciated.
Thanks in advance.

Uh -- get a new boss first?

Have you done a web search? This is the sort of thing that I never seem
to find joy with trying to scratch up code from the Internet -- if you
find anything at all, chances are it doesn't work. In fact, you may be
best served if you _do_ find something that is _clearly_ not applicable.
Then you can show it to your boss, say "this is the best that's out
there", and suggest that you start writing code.

_Then_ you'll need to learn the basics!

Document what you search for -- if your boss is convinced that its out
there and it isn't then saying "I couldn't find it" won't prove to him
that it's not there -- it'll prove to him that you're not there. Saying
"I tried this, and this, and this and still no luck" will be your best
chance if it really isn't out there.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.

In my practice, quite often I have to fix up things which are already
messed up. How I wish that I could start everything from scratch.

Get a sample code then. What is a problem?

Hm. And what do you offer in return for help?

Have you read the docs that came with your DSP board? Is there not
sample code to grab data from the A/Ds and transfer to the PC memory?

Out of curiosity, I just looked at the II website. This took me approx
45 seconds. Under "Support-->Forums" there is an "Application Notes"
forum, and an example called:

"High-speed Data Logging to a RAM disk". Might that be the sort of thing
you want?

If it is, can I claim a consultancy fee from II? At 1$ per second, I
reckon I am cheap at twice the price.
