In this case you have to edit the top_block.py by hand, this cannot be done from the GRC.

You just need to perform these steps: Step 1: In GRC (gnuradio-companion), open the flowgraph and then press F5 (or, click menu Build --> Generate) This will generate a new file: "top_block.py" The file is located at the same directory where your *.grc file is located. Step 2: Open a terminal, cd to directory of the top_block.py, execute it: python top_block.py With this you will see all python outputs at this terminal. Is this exactly what you asking for..? P/S: In fact Marcus Muller had already answered your question in above message. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Re: [Discuss-gnuradio] Calling functions from flowgraph ?
Hi Abouda, in GNU Radio, there's no real main loop; I don't really know what you're trying to do. The python files GNU Radio generates are executables, you can just run them in a terminal without GRC :) Greetings, Marcus On 05.06.2014 11:07, Abouda Yassine wrote: > Hi everybody, > > well,I had a python script which works with gnuradio and outputs results on > the terminal.To make it more visual,I made all the blocks on the > gnuradio-comapnion but now I would like to output the results on the > terminal which means I have to call the main loop in the python script from > the flowgraph to get the job done.In other words,when I hit the button > execute the flowgraph,I want to see the porgram running.I hope you > understood what I'm trying to do.So,how can I do that? > > regards, > -Yassine > > > > ___ > 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
[Discuss-gnuradio] Calling functions from flowgraph ?
Hi everybody, well,I had a python script which works with gnuradio and outputs results on the terminal.To make it more visual,I made all the blocks on the gnuradio-comapnion but now I would like to output the results on the terminal which means I have to call the main loop in the python script from the flowgraph to get the job done.In other words,when I hit the button execute the flowgraph,I want to see the porgram running.I hope you understood what I'm trying to do.So,how can I do that? regards, -Yassine ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
