Hi all,
after some time searching through the list archives I was not able to
find out what happened to the multi_usrp.py file which is needed to run
the the multi_usrp/multi_usrp_rx_cfile.py and
multi_usrp/multi_usrp_rx_oscope.py in the examples directory.
I found in the svn log, that they haven’t been converted to hier_block2
yet. (Rev. 7607 afaik)
After changing some code in usrp_multi.py and manually copying it to the
python dist-packages directory, I was able to run the
multi_usrp/multi_usrp_rx_cfile.py, which seemed to work fine. Looking
at the samples in Octave they seemed fine too.
However I was not able to get the multi_usrp_rx_oscope.py to run, as I
was not able to convert the scopesink stuff in it to scopesink2.
Although it’s flagged as unsupported, I think it would be nice to have
this kind of examples running. If there’s interest in fixing this I
could send my changes for others to check. If there’s
no interest in fixing it I don’t see the point in keeping the example in
current versions.
Best regards,
Moritz

It would be great to have it running. Please fix it and send a patch.
FWIW, the reason it’s still there is so that somebody who cares (== you)
doesn’t have to start from zero

Hmmm, didn’t I send a patch out way, way, back (last summer?) to convert
the
multi_usrp.py code to hier_block2? Perhaps I forgot to hit the send
button.
I can’t find it in a quick search just now. FWIW, I don’t remember ever
getting the multi_usrp_oscope working, but I was mainly working with
multi_usrp_rx_cfile.py at the time.

I’ll do that, after trying for a whole day, I finally sent the message
to the list, and about 20mins later I managed to make some progress :-/
However I still have not managed to get the ‘-s’ switch for attaching
the counters to the scopesink to work together with 4 channels.
I’ll have another look and sent the patch next week.
If I will still be to stupid to complete the somewhat simple task of
determining the correct number of inputs for the scope with 4 channels
and ‘-s’ switch from options.nchan and options.show_counters I will cry
again to the list for help
Does someone know what the maximum number of channels one can attach to
the scopesink2 is?

The current limit is 8, but it’s arbitrary. See gr_oscope_guts.h
