Re: [Discuss-gnuradio] Vec Length

Hi Josh, One more thing. Where can I find the class that has the member function real() implemented? I tracked the conversion of complex to float in the gnuradio code in ~/gnuradio/gnuradio-core/src/lib/general/gr_complex_to_xxx.cc . And came across the line: out0[i] = in[i].real (); But I am no

I guessed so. However, I am stumped as to how to make my complex short a real short. Do I have to write my own code or is there a gnuradio-companion method? Nick On Thu, May 12, 2011 at 1:34 PM, Josh Blum wrote: > > > On 05/12/2011 10:18 AM, Nick Othieno wrote: > > Hi all, > > > > What does th

[Discuss-gnuradio] Vec Length

Hi all, What does the Vec Length parameter signify in gnuradio-companion blocks? I have realized that Vec Length for the USRP2 source is by default 2 and cannot be changed on the GUI. How can this be changed to 1? In my case, I have set the USRP2 UHD source Input Type to Short. I am assuming that

[Discuss-gnuradio] RDS block doesn't find python module

Hello, I have installed GnuRadio 3.4.0 from Git on Ubuntu, now I am trying to setup the RDS block from https://www.cgran.org/wiki/RDS. I have followed the instructions (configure, make, make install) and apart from a missing italian translation file, it seemed to work (I used make -i). However,
