[Discuss-gnuradio] How to tell Flowgraph to Stop in Work()?

2017-04-28 Thread Ghost Op
I'm working on a module in C++ and when a condition happens I want my work function to signal to the flowgraph to stop. I saw some references for python to self._top_block but does anyone have a suggestion on how to do it in C++? Thanks! ___

That's fine for low rate stuff, but for Mehmeto's application, he probably needs to be more coherent. Correlating on a preamble would be a good idea, I think. On Fri, Apr 28, 2017 at 9:04 AM Vitt Benv wrote: > Hi Mehmeto, > in my opinion and in my experience with LEO sats,

Hi Vamsi - it looks like you're not linking with Volk directly; indirect linking (via one of the GR libraries) doesn't work. Check out any of the various OOT modules that do that linking for specifics. - MLD On Fri, Apr 28, 2017 at 12:12 AM, vamsi krishna wrote: > > I get the following error when

If you want to change the default size you can look in /usr/local/etc/gnuradio/conf.d/grc.conf and change the line `canvas_default_size = 1280, 1024`. The path might be different on your system. You can run `find / -name grc.conf 2>/dev/null` to hunt it down. On Fri, Apr 28, 2017 at 5:05 AM,
