Re: [Discuss-gnuradio] Re: change variables in the FFT Plot the 2.
I do not understand why you have the problem? Do you have the latest gnuradio trunk installed? http://gnuradio.org/svn/gnuradio/trunk I have the SVN Version 2009-Jan-28. It was this changeset on jan 28th http://gnuradio.org/trac/changeset/10327 Make sure the files are installed. good luck -josh ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Do you have the latest gnuradio trunk installed? http://gnuradio.org/svn/gnuradio/trunk I have the SVN Version 2009-Jan-28. Aha, I believe that I added the set_sample_rate callback recently (possibly in February). svn up! Further on everytimen i open my *.grc file, the deletes the manually inserted class-method, so there must be a Problem. When you generate or run a flow graph in grc, the generated flow graph is always overwritten. Also, I am concerned that the gl fftsink aborted/segfaulted. Can you run the flow graph in gdb and send the traceback? Yes i will try this and post the message here. Another important Point, Is there a possibility to save my manually inserted python commands in the file without loosing this by the next start of ? Nope, too complicated! If you want to change things: the best way is to manipulate the xml block wrappers or make your own custom wrappers: http://gnuradio.org/trac/wiki/GNURadioCompanion#AddingCustomBlocks And here is fftsink: http://gnuradio.org/trac/browser/gnuradio/trunk/grc/data/platforms/python/blocks/wxgui_fftsink2.xml Regards Markus ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Please follow the directions to enable the wxgui - open gl sinks: http://gnuradio.org/trac/browser/gnuradio/trunk/gr-wxgui/README.gl Let me know how it works for you! -Josh feldmaus wrote: feldmaus gmx.de> writes: Not really RIGHT: def set_samp_rate(self, samp_rate): self.samp_rate = samp_rate self.wxgui_fftsink2.set_samp_rate(self.samp_rate) How is the Name of the method to set up the samp_rate ? self.wxgui_fftsink2.set_sample_rate(self.samp_rate) ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
