Re: [Discuss-gnuradio] LIBUSB_ERROR_PIPE and "improperly" stopping gnuradio

Hi Lefteris, does the same happen when you just press any key instead of killing the script? Greetings, Marcus On 05.11.2014 03:40, Eleftherios(Lef) Kampianakis wrote: > Hello all, > > I am facing a strange problem when I am starting my gnuradio script. I keep > getting the following message. >

Re: [Discuss-gnuradio] BER VS EBNO

Hi Lucas, that graphic was generated using the python file that is linked to directly above the graphic, and not by adjusting some slider. I think you should really read that source code, it will bring a lot of insight into the problem at hand. Best regards, Marcus On 05.11.2014 14:55, Lucas Lope

Re: [Discuss-gnuradio] Hierarchical Block in c++ not working, linker or swig problem

Hi, I forgot to edit the CMakeList.txt to add the GR components that I used (the line set(GR_REQUIRED_COMPONENTS... ). I still find it strange, that on one PC I got a linker error (which obviously was the Issue and led me to the solution) and the other one builds without complaint but okay.

[Discuss-gnuradio] Markup GRC Flowgraph

Hi all, I would like to know if there is any way to add textboxes to a GRCs flowgraph for notes and documentation? Thanks, Rich ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Try a CTRL-F and search for "note" block. I think it's under the misc folder also. It only lets you do one line. Lou Richard Bell wrote > Hi all, > > I would like to know if there is any way to add textboxes to a GRCs > flowgraph for notes and documentation? > > Thanks, > Rich -- View t

GR nation, My first attempt at this question was foiled by my e-mail program's insistance on sending html. I apologize for the repeat. I am interested in using controlport for monitoring, debug, and control of a flowgraph as part of a larger distributed signal processing system.  I'm currentl

Hello Thank you for your reply. No it happens only when I kill the script. let me give you another example. I have a flowgraph in GRC that looks like this: USRP source --> USRP sink I connect the B210 to the macmini via USB3 and press the "execute the flow graph" button. The script is execut

Sylvain thank you for your reply, Ok, what about the python script in my previous message? How can I write my code in order to prevent the LIB_USB_ERROR_PIPE message. No matter how I stop the gnuradio script (e.g. catch keyboard interrupt and issue stop() and wait as in my original post), I always

Re: [Discuss-gnuradio] LIBUSB_ERROR_PIPE and "improperly" stopping gnuradio

Thanks again for your (rapid) response! 1) I think there should be somekind of bug report on that although I dont really know how to do this 2) I was thinking of a workaround through lsmod (similar to modprobe in linux) to emulate the removal and re-insertion of USB, this way I could write a simpl

Hi Ed - The actual link command was not included in the output you provided, so it’s difficult to say exactly where the issue lies. But, the basic cause is that “libSDL.dylib” is not being included in the link command, and/or it does not contain the various “SDL_*” symbols that are not being fo

Hey Tom, I'll pull together the git branch and let you know when it's ready. As for gr_spectrogram_plot, we do use the standard GR header format, with some "extras" such as center frequency. I think it would be useful in the metadata format to have center frequency, seconds/sample, and file l
