[Discuss-gnuradio] the problem with the uhd_fft.py modified
Hi,everyone I 'd like to watch the OFDM constellation,so I modified the uhd_fft.py, I added some code as follows: demod = blks2.ofdm_demod(options) stream = gr.vector_to_stream(8,200) self.connect(self.u, (demod.ofdm_recv,0),stream,self.scope) self.connect((demod.ofdm_recv,1),gr.null_sink(1)) when modified the code, the graph stopped after running one or two seconds, it looks like not receive any data. Could you tell me where is wrong? I appreciate any help, thanks in advance.

Re: [Discuss-gnuradio] How to display constellation in gnuradio
I have found it, but i'd like to add FFT before sopesink2 of wxgui, there a error in it. the error info is itemsize mismatch:gr uhd usrp source(1):0 using 8,fft_vcc_fftw(14):0 using 4096,how to have their itemsizi matched? 2011/9/5 Josh Blum j...@ettus.com: On 09/04/2011 04:42 AM, guojun chang wrote: How to display constellation in gnuradio? I know that uhd_fft.py can show a window, but there is not anything what i need. I appreciate any help, thanks a lot in advance. The both the qtgui sink and wxgui scope sink has an XY mode to plot complex input. -josh ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
