Re: [Discuss-gnuradio] QT GUI (Constellation Sink) Update Period (Refresh Rate)

​The error at run-time was caused by setting one of the Alphas > 1. That's fixed. I set the trigger to Free and this seems to resolve the problem. I have also split them up so there is only one input per plot as it looks better anyway. Thanks! From:

[Discuss-gnuradio] VOLK tests fail on E310 and other neon

Hi, I've been trying for the last week or so to get VOLK to build on the E310 or on another ARMv7 mini computer (Odroid XU4) that I have access to. I've tried git HEAD on down the the oldest release available on libvolk.org and depending on the version, they fail 2 out of the following 3 tests:

Re: [Discuss-gnuradio] QT GUI (Constellation Sink) Update Period (Refresh Rate)

Thanks Johannes, I am currently trying with different trigger modes, and just one input - great minds think alike :) Unfortunately there is no data at any higher rates in the flow graph, its a complex relay implementation and the source sends packets with very low duty cycle. This is surely

Re: [Discuss-gnuradio] DPSK DEMOD sync out option

It'll probably be best if you do that. Thank you for looking into it. I have another question while I have you. I was hoping that sync output was going to be some sort of magical correlate/sync option. About a month ago I was trying to get a messaging system to work over the air using two

Re: [Discuss-gnuradio] Creating QT GUI out-of-tree blocks in Python

Hi Patrick, this should work. I meddled with this very subject a while back; the idea was that you can just replace the "Qt App framework" boilerplate that GRC generates with your own PyQt/PySide application. https://lists.gnu.org/archive/html/discuss-gnuradio/2015-09/msg00038.html Best regards,

[Discuss-gnuradio] Creating QT GUI out-of-tree blocks in Python

Hi everybody, I would like to create out-of-tree modules for the GRC, that show graphical interfaces (GUIs) created with QT. As the purpose of these blocks is mainly for prototyping only, I would like to do everything quickly in Python, without the need of additional C++-files. Here is what I

[Discuss-gnuradio] DPSK DEMOD sync out option

Hello all, I was wondering if anyone knew what the sync out option did on the DPSK Demod block. I can't seem to find any documentation on it, and I'm also having trouble finding the source code for it. Does it just use the generic mod_demod file? Thanks, Logan Washbourne Electrical Engineering

Re: [Discuss-gnuradio] QT GUI (Constellation Sink) Update Period (Refresh Rate)

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi David, I can't find any obvious mistakes with the configuration. Did you try to play around with different trigger modes? Did you try to only have one input? It may be an issue with different rates from your input data and output data streams. Did

Re: [Discuss-gnuradio] DPSK DEMOD sync out option

Hi Logan, skimming through the xml that defines the DPSK Demod block, gr-digital/grc/digital_dxpsk_demod.xml, reveals that this option sets the "sync_out" variable, which is used nowhere. This means that it's without effect. Do you want to delete that option and open a pull request, or should I
