[Discuss-gnuradio] GRC - python code generation quirk for Function Probe with empty BlockID

2014-04-25 Thread Darren Long
Hi, I've been pottering around in GRC trying to get a pair of function probe's to update the QT fosphor GUI sink's centre frequency by calling self.set_freq(float(subprocess.check_output(['/usr/bin/rigctl', '-m', '2', 'f']).strip())) at 5Hz and self.set_samp_rate(self.samp_rate) at 20Hz.

Very nice. I've only just changed to using the gqrx repository instead of building everything from source, but I couldn't resist having a go at getting this working. I've managed to get the demo program running, but I've not been able to do anything else yet. Hopefully Alex will be able to

Hi Alex, The benchmark utility source is in gr-fosphor/lib/fosphor I had to run make manually, but in order to get it to build I had to bodge it. The changes I made are in the diff below. === diff --git a/lib/fosphor/Makefile b/lib/fosphor/Makefile index a1ea187..3500d64

Hi Sylvain, I can't get osmocom_fft to run, due to a problem inporting fosphor. It runs OK without the -F argument. Not sure what is wrong yet. Everything seemed to build and install OK. Please see the output below. Also, should there be any new blocks in grc? Cheers, Darren

Good call. I applied the 4 patches and now I can run osmocom_fft with the -F option succesfully. $ osmocom_fft -F -a fcd=1 linux; GNU C++ version 4.8.1; Boost_105300; UHD_003.005.004-0-unknown gr-osmosdr v0.1.x-xxx-xunknown (0.1.1git) gnuradio 3.7.1 built-in source types: file

Yep, I concur. It is blazingly fast at rendering with the HackRF :) Can we control any options on the sink? For example frequency scale, waterfall rate, etc. A callback would be nice too. I'd like to use the fosphor sink in my gr-kx3 script that I use to control my HF transceiver. This

Hi Chris, Might I be so bold to suggest that in your efforts, you consider using the gr-osmosdr abstraction (http://sdr.osmocom.org/trac/wiki/GrOsmoSDR) so that the RTL-SDR could be used too. In fact it supports UHD, FCD and RTL-SDR, and works well in gqrx for example. Sorry for being cheeky :P
