Does the current USRP2 FPGA/firmware release allow for a PPS interrupt
handler? I've tried adding these lines to the txrx.c firmware app:
static void
test_pps_handler(unsigned irq)
{
putstr(Got to PPS handler at time:);
puthex32_nl(timer_regs-time);
pic_regs-pending =
Yes, connecting to SPI is an interesting option. We'll consider looking at it.
Is there any documentation for this bus available?

Dear Thomas and Tim,
Thank you for replying all my questions previously. I have another
question for the list. Hope you don't mind. I wrote a demod for dbpsk. I
had to because I am spreading/despreading packets using dbpsk modulation.
Hi Eric ,
We here have just got introduced with gnuradio and are seeking support on
few problems with usrp2 .
We are unable to get the correct output of usrp2_fft.py after
installation and upgrading to 11370s (fpga and s/w) . No carrier freq seen
only noise at ~ -100 dB for different values of

Hi people,
I and a friend will try the OpenBTS (we aim to make a free GSM network),
and I'd like to know if I can use a DBSRX in the RX chain (just for
testing purposes), and a RFX900 in the TX chain.
I already own a DBSRX, so them I'd have to buy only a RFX900.
I'm following this page:

We expect to be able to get VCTCXOs in modest volumes for less than
$30. The TCXO we are using now is $23. Most of the cost of the
clock doubler board is the labor for getting it assembled locally in
small batches.
When/if the FPGA firmware gets fixed, we can use a 26 MHz
Hi all
I am making progress. Using GRC and the information from Joshknows.com I
was able to build the blocks for dial_tone and got it to work. But I am
unable to get the volume and noise sliders to function. I have spent several
hours trying to solve the problem but with no success. I'm sure the
Hi all,
My current equipment seems can't handle normal parameter setting for
OFDM test. The receiver can only receive very small number of packet
correctly. One possible reason maybe because the host can't catch up the
process speed. So, I would like to modify some paramters and reduce the
Does any one know what is the sample per symbol rate in OFDM gnuradio? Or
how to change the value?
Thanks,

Steve,
I am not sure what the problem is. Can you be more/very specific?

Hi,
I tried to log the data from benchmark_tx.py using dbpsk modulation but for
some reason it doesn't happen. --log option works on other computers but not
on my laptop. I have gnuradio-3.2svn installed.
Thanks,
