Hi All,
Can anyone shed some light on how the FX2 firmware / GPIF handles
simultaneous reads and writes? I mean if I set up my USRP1 to receive
and transmit simultaneously, what is happening exactly down there at
the GPIF level? Given that there are two GPIF waveform configurations
one each for Re
Just so you don't think I gave up all disillusioned.
I have figured out how to change the GRC generated python files to not
refer to the wx libraries, only takes a couple of lines to be edited.
The result is that I can now create flowgraphs in grc on my development
vm, copy the python file to
Hi All,
I was wondering if there is any buffering happening on the host and/or on
the USRP (USRP1 and N210) when the UHD send() and recv() methods are called?
Thanks,
Shiva

Thanks Josh. Getting the newest gnuradio from git solved the uhd
problem, but now gnuradio is broken. I know it must be some path problem
but I have tried the usual tricks: I set my
PYTHONPATH=/usr/local/lib/pkgconfig/dist-packages and

Yes, that was typo.
PYTHONPATH=/usr/local/lib/python2.6/dist-packages
I did mean dist-pakages. I have three directories in dist, gnuradio
grc_gnuradio usrpm. And nothing in the site-packages.

Where does one get the uhd version of the FPGA sources?

In either the uhd git tree or by getting the ise12 branch from the FPGA
git tree.

Yes of course. There are buffers in the host and device (fifos).

Jeff, Al, Brian,
A little bit delayed thank you to all of you!
So, I took my time to investigate TI offer further and after all I
should agree that TI support of open-source is indeed much more decent
then that of Freescale. Combined with Jeff's comment about the number
of developers who work wit
Hi,
we are doing some research here on decoding 802.11g using GNURadio. As
far as i know there is code available for transmission of 802.11g frames
on CGRAN but no receiver code. Is there any work going on for the
receiver side right now? Is it theoretically possible to decode a signal
receive
This is quick and off the top of the top of my head but here are some clues:
1)The appropriate Makefile.srcs should call both 'fifo_xlnx_2Kx36_2clk.v' and
''fifo_xlnx_2Kx36_2clk.xco'
2) In the log (capture all ISE output to a file for review by redirecting
STDOUT) you should see the following l
Is there a list of options can be passed to uhd::device::make ?
So far I have found: "addr", "recv_buff_size" (is this in samples or bytes?).

Hi,
in libusrp2 samples are sent to device in packets of 370 samples,
while in UHD now the max is 362,
is there any way to have 370 in UHD as well ?

Yes and maybe: The default recv_frame_size is the mtu of 1472 for a
maximum length udp pack
