Hello,
Just one basic doubt.
How do I send and receive data between the computer and the ADC-DACs on the
USRP?
I mean, how do I read that data from the board or send to it using software?
Please clear this one in detail.
Thanks a lot.
Regards,
Kuntal

The RS Codec tests pass, the vmcircbuf tests pass and then a string of

gives a clue.

This thread related to the USRP version 4.2, 10-2-2006. As you point
out, the v3 boards have a smaller heatsink pad.

Hi,
Thanks for the replies.
Yes, I have had it working with the rational resampler, but I'm trying to
eliminate that block. I'm eventually going to use a very low power, fanless
pc to run the software, so we're trying to shave off as many cycles as
possible.

Hi All
When seeded with a positive number gr_noise_source_X seems to always
return the same sequence.
i.e.
call gr_noise_source_f(gr.GAUSSIAN,1,Z) where Z > 0 the sequence is
always the same. Called with a negative seed (Z < 0 ) it behaves as I
would expect.
Am I missing something?

We definitely have work to do. Portaudio is the ONLY thing I can get to
work the PS3 sound system but not in gnuradio.
The pieces in the bin directory for testing portaudio that open the sink
only work. I can produce tones, hundreds of tones, do latency tests, etc.

I believe the USRP needs a 3 Vpp clock in, and this TCXO only outputs
0.8 Vpp.

Hi,
I'm trying to demodulate and decode a CPFSK signal generated by a

had success. I noticed that the gmsk code is in the limbo directory, so
I'm not sure
