Question UHD, WINDOWS

GNU Radio
1

Hi,

As I mentioned a few times here, I really can’t install that GNU Radio
in
Windows environment (I followed all steps found in those descriptions
regarding,
how to install it with MinGW or CygWin). So I have to give it up and try
to
focuse on other solutions like UHD or maybe others. What I want to do is
to make
some simple data transfers on different frequencies, basic communication
with
some modules made by me. Really I don’t need all that python stuff and
all those
dependencies problems. I was even thinking to control USRP from my
application,
it would be much faster than using Python, but how to write the firmware
into
the FPGA. OK, I got it, through that nice USB transceiver. After
installing the
USB driver when the USRP1 is connected to the PC it shows up the device
with
that FFFE VID and 0002 PID. Could anybody tell me what to do from this
point to
be able to program the firmware into the FPGA or maybe to change the
firmware of
the EZ-USB FX2 transceiver? I suppose after I will program the rbf file
into the
FPGA I could start to get and set things, send orders to the board to
set
frequency, decimation, sampling rate or read/write raw data. Commands to
drive
the USRP1 and my WBX daughterboard I could get from written source code
(ex:
http://gnuradio.org/redmine/repositories/entry/gnuradio/usrp/host/lib/db_wbxng.cc),
anyway I’ll start to make the whole program with the help of
FreePascal.

A second alternative would be to use UHD (documentation is very
poor)because
it has support for USRP1, but after I read that I would have to get I
don’t know
what program to do something with the source code and to compile the UHD
source
code and other steps I started to think if it’s a good idea, maybe I
will have
the same problems encountered when installing GNU Radio on Windows OS,
why
couldn’t they provide a simple DLL file for using it on all Win OS’s.
Could
anybody tell me how does UHD behave in Win OS? It’s easy to use it?

As a final answer, based on my description I do expect too much from
this
USRP1+WBX hardware or there are other people heaving the same problems?

Thank you very much.

Best regards,
Florian E…

I understand that it can be frustrating to get started in a completely
new system where the learning curve is fairly steep. However, don’t give
up yet. It is probably worth getting Gnuradio installed via Cygwin in
order to accomplish what you’re trying to do without reinventing the
wheel. And it is certainly less painful to figure out how to install UHD
than it is to rewrite it from scratch. You might even consider
installing Ubuntu or another Linux distribution, even in a virtual
machine, and running Gnuradio from a Linux environment. Gnuradio tends
to be better-supported on Linux, and the community of users who can help
you is larger.

UHD and Gnuradio are not alternatives to each other, they are
complementary. UHD is for getting samples from your USRP onto your
computer. Gnuradio is for doing something useful with those samples.

At any rate, you will have much more success getting help with your
Gnuradio and UHD problems if you can describe the problem you are having
in detail, with the procedure you have followed so far, and with
cut-and-paste results.

I’m posting a uhd, gnuradio, and misc dependencies installer. Make sure
to set your PATH to the installed library dirs. The other pre-reqs come
with installers you can get from the internet and maybe I will upload
them later (python, numpy, pyqt, pygtk, etc…)

The performance overhead of python is irrelevant because its not used in
