Re: [Discuss-gnuradio] various USRP GUIs freezing

[Martin Dvh]

I am having this problem all the time.
The defaults for the fft display are to try to display 15 fft's a second
which is too much for anything but the fastest  processors.

In the usrp_wfm_rcv example several fft's are displaying at the same time
which worsens the problems.

I allways add the following parameter to all ftt's.
fft_rate=5
What this does is to tell the fft gui to try to display 5 fft's a second in
stead of 15.
For me this solves most gui_freeze problems.
If you still have the problem then go even lower as 5 or disable the fft's.
(change the if 1: to if 0: in front of the code which opens the fft display)

Maybe it is a good idea to add fft_rate  as a commandline parameter to all
examples.
And maybe lower  the defaults in the fft gui.

Another problem which I have witth the examples that it always barks at the
import powermate line (I don't have a powermate)
If I coment the line out the code runs fine.
Anybody got a solution for this?

Greetings,
Martin

How high is the process load when you are running the code? I
sometimes experience the same behavior, but it usually goes away after
a couple of seconds. It might be an issue with ram if you have a lot
of programs concurrently open. 256MB isn't much. Can you see how much
memory is in usage?

You can use top and free to get this information.
