Hi Circuits...
(Apologies for any typos.)
Welcome to UNIX.COM.
Well Linux is catered for inside the OS section of the forums but judging by your post you are into, using an AMIGA term, 'banging the metal', much like myself.
This site is a *NIX related site and is primarily to help people with *NIX related problems, usually programming problems.
Having said that many here are electronics minded and can help solve HW, SW and other problems related to *NIX OSes.
Read the rules first and when asking questions be as accurate as you can and stick to said rules:
Simple rules of the UNIX.COM forums:
there are some remarkably bright guys and gals on here and have a deep understanding of the *NIX environment.
If it is more HW related then these forums might be of interest:

If you don't get an answer to your post then it could be that no one has an answer, not that we are ignoring you.
Enjoy you stay and never post with the word 'urgent' or any synonym of it in the title. It could well be ignored and locked.
Bazza...
