Usrp1, uhd?

Hi mr. Josh B.,

  I would like to ask you something if you allow me. I don’t want to
bother
you, but I would like to ask you a few question regarding the UHD and
it’s usage
with USRP1 and Windows.

   I posted a differnt question mainly focused on Windows and GNU
Radio, how
all these can be used and what are the steps to make it work. I was
asking that
because I couldn’t found any tutorial or other document where it would
be
explained what and how has to be made to start to work with these.

   The OS I’m using each day is Win XP and I’m developing software in
VisualStudio and a few other development environments, so I like windows
and I
can do anything here. I’m not familiarized with Linux and others. As I
mentiond
in a previous post I have to make a project where I have to use some SDR
hardware therefore I have bought an USRP1 hardware from Ettus. It’s
connected to
the computer but here I had to stop because I couldn’t find any clear
way to
make it work. In this post I won’t repeat what I have written in the
previous
one so the question is related to UHD. It’s something I would like to
work with,
to have some functions in a DLL file and to be able to call those
functions to
read out some data from the USB data stream, to call different functions
to make
some data processing, I don’t mind if I will have to install python
and GNURadio (maybe someone in the previous post will explain me how
they
installed these on Windows) and to call a function with the name of the
script
(that will take some parameters and give back others) and some
parameters to be
able to extract some data from a coded stream.

   To tell you the truth I don’t know what’s your vision about the UHD,
how you
want (I read that you are developing the UHD)Â it to work, and how is
working
right now? What are the limitations regarding the usage of UHD and
USRP1? Could
I make an application to read out a byte of data from the USB stream and
to
demodulate it, to get the real values (ex: to send from a device a value
$5C
that will be modulated by a hardware and transmitted while at the other
end to
be able to receive with the USRP that, to demodulate and to get the $5C
value).
I suppose that the whole UHD has to be flexible therefore it should be
able to
allow user to use different demodulation and other scripts. Like in the
previous
example, if the modulation is ASK or OOK, that is a simple situation but
what if
it’s bout FSK or other more complicated, than user has to have the
ability to
make a script that has described the whole demodulation process, how to
take the
stream and give it back like (executeFunction (InputStream;
OutputStream;
pythonScript);).

   I’m asking you some help, or links, to get the picture of what the
UHD is
working; how could we extend it, to make a really flexible system; how
it can be
used on Windows OS? Maybe if we (me and those who would like to use the
UHD)Â will get some help we will be able to use it and to come up with
some
end-to-end projects (explained on real hardware, and making real data
transfer).

   Maybe after several answers from different persons there will be
possible to
make a document with all suggestions and ideas so that these questions
will not
be asked in the future.

   Excuse me for bothering you with my questions, but I really don’t
know
anybody else who could know much more about the UHD. Thank you for any
answer
and any suggestion you might have. I wish you and to all those who are
reading
this post a wonderfull day.
