Hi,
From my measures:
Bit stream 0.8 original : logic elements 56%, Memory bits 27%
One cordic unit is 6% of the logic elements

Hi,
Matt in a previous thread you were talking about making d/b that let
DC component pass:
If there is enough interest, I might make such a set of boards. If someone
else
is interested in the design, the BasicRX/TX are a great starting point, and I
can offer guidance.

Hi,
thanks for the solution, maybe i'll try with a different transformer
to shift the cutoff.
When i'm inspecting the my FIR output, it's really difficult to
measure a 30ns (one sample) delay if the signal is not clean.
This is unrelated to the DC component issue.
Blame it on my bad
Hi Eric,
I need for my project (channel simulator) to send parameters to the FPGA.
This issue was raised in this mail:
http://lists.gnu.org/archive/html/discuss-gnuradio/2005-03/msg00127.html
Is it possible to send parameter to the 'serial_io' module from Python code?
Here speed is not a
Hi,
i think i just hit the same issue
From this simple code (no display what so ever):
fg = gr.flow_graph ()
u = usrp.source_c (0, 64, 1, 0xf0f0f0f0, 0)
n = gr.null_sink(gr.sizeof_gr_complex);
fg.connect(u, n);
dest = usrp.sink_c (0, 64)
siggen = gr.sig_source_c
Hi,
correct me if i'm wrong, but I think the only way to do it is to go
through the PC with the official Bitstream.
At least i didn't see anything to do it in the verilog code. I'm
trying to do it (with a FIR in between) for my channel simulator
project. But it's still far from working.
BTW,
Good day,
this file is missing in the 0.8 tarballs, I got mine browsing the CVS.
The path is : usrp-0.8\fpga\sdr_lib\cic_int_shifter.v

Hi everyone,
Our project is to use the USRP as a DTV channel simulator to test the
respective quality of DTV set boxes. That means to be able to
attenuate the signal, add noise and simulate echos from reflexions on
mountains for example.
The biggest question is how to do it. One way would be to
Hi,
i'm setting a system for gnu-radio, managed to install software (make
check ok), the USRP is correctly detected and i flashed the
daughterboards.
When i try to run basic TX examples i receive an error from
_submit_urb (listing at the end).
I tried CVS and tarballs with no luck.
I'm running a
Hi,
I managed to install Gnu-radio project on ubuntu (based on debian)
without the 'make check' error message.
Here is a small walk-though. I'll add a Wiki entry if you think it's worth it.
