Re: [Discuss-gnuradio] how to get dqpsk2 block?
Thanks! I've started to understand this a bit. Now it's like this: gcell gr-gcell gr-audio-jack gr-audio-osx gr-audio-portaudio gr-audio-windows gr-comedi gr-video-sdl grc These components will not be built. I wonder if I need gcell and gr-gcell. Definitely need grc. Here is a log http://old.nabble.com/file/p29504085/config.log config.log I really can't understand why grc wouldn't install. -- View this message in context: http://old.nabble.com/how-to-get-dqpsk2-block--tp29448241p29504085.html Sent from the GnuRadio mailing list archive at Nabble.com. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

I think that's needed if you want to run GNU Radio on the IBM Cell Broadband Engine processor, which is used to power the Playstation 3. http://gnuradio.org/redmine/wiki/gnuradio/PS3FC8Install The Cell processor on the PS3 has 2 PowerPC processor units, and 7 vector processors (or SPUs, 1 of a total of 8 is disabled to improve yield). The IBM Cell Blades have chips with all 8 SPUs enabled. Best regards, Elvis Dowson ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Record file format
Does anybody know the file format? that i recorded signals into files and I want to read them for analysis. what is the format of the data written/read by filesink/source block (I used GRC) And I used the USRB source block and choose complex type of output So does the file i record are complex?(The signal that I received by USRP are real signal(beacon signal)) and i saw that they are code to read the file from matlab named read_*_binary.m and i see that thay got * = complex,float,short,char ,so what kind of these type do i use or will i just use the same with what kind of signal i receive? like i receive real signal so i use float , does it correct?

[Discuss-gnuradio] 'gr_hier_block2_sptr' object has no attribute '_write_fpga_reg'
Hi all, I'm working on a synchronization block to allow the transmitter and receiver to co-locate on the same motherboard and work alternatively, transmitter working for 0.5 second then receiver working for 0.5 second, and then repeat this process. I'm using USRP1 and LFTX/RX to develop my transmitter and receiver, which work well when transmitter and receiver are plugged on two USRP1 mother board. I'm trying to write fpga register FR_MASTER_CTRL to enable transmitter board or receiver board every 0.5 second, in order to implement tx and rx working alternatively. owever, i got an AttributeError File /home/john/gnuradio/gr-iono/usrp_ionsonde_control.py, line 197, in set_reset self.write_mode() File /home/john/gnuradio/gr-iono/usrp_ionsonde_control.py, line 166, in write_mode self._u._write_fpga_reg(FR_MASTER_CTRL, self.mode) File /usr/local/lib/python2.5/site-packages/gnuradio/gr/hier_block2.py, line 50, in __getattr__ return getattr(self._hb, name) AttributeError: 'gr_hier_block2_sptr' object has no attribute '_write_fpga_reg' What's the problem may be? Could this fpga reg be written every half second or even 20 microseconds? Thank you so much for help.

[Discuss-gnuradio] Locking USRP2 to external 10MHz reference in the UHD/GRC universe
How do I arrange to lock the USRP2 to an external 10MHz reference in the UHD+GRC world? Is there an arg I can pass when I create the UHD USRP2 simple source in GRC?

[Discuss-gnuradio] doubt about the the DC offset
Hi all: when I run the test program test_usrp_standard_tx/rx.cc, I found that the DC offect is set to 4M. So can anyone tell me how this value come out and where can I find the process of setting this value? and can we set other values to instead of this value?

Re: [Discuss-gnuradio] eye diagram sink
The usrp_oscope has a mode where you can do channel 1 vs channel 2. Try that with real on channel 1 and complex on channel 2.

Re: [Discuss-gnuradio] Locking USRP2 to external 10MHz reference in the UHD/GRC universe
Swig brings in the clock config struct into python. The python code looks like: from gnuradio import uhd ccfg = uhd.clock_config_t() ccfg.ref_source = ccfg.REF_SMA ccfg.pps_source = ccfg.PPS_SMA ccfg.pps_polarity = ccfg.PPS_POS so the the grc xml wrapper you need that bit of code along with $(id).set_clock_config(ccfg) -Josh On 08/22/2010 04:52 PM, Marcus D.
