Re: [Discuss-gnuradio] fftsink and scopesink refactored

[Jonathan Jacky]

I tried the new fftsink and scopesink on Mac OS X 10.4.3 Tiger.

Both of them work without modifications on a 1 GHZ Powerbook G4.
Previous versions would not always work --- they would start up
and display a blank window, with the twirling beachball icon that
indicates the program is busy, apparently because wxPython on the Mac
couldn't keep up with the data.

Now scopesink just barely works on the 1 GHZ Powerbook.  With the timebase
at 100 us/div or more, the display frequently freezes and the beachball
appears, and the only escape is to type ^C into the terminal
window.  At smaller values of us/div (fewer cycles on the display) the
display updates and the controls are responsive.

scopesink works well (no beachball) on a 1 GHz PowerMac G4 (dual
processors) and on a 2.7 GHz PowerMac G5 (dual processors).

Now fftsink works well even on the 1 GHz Powerbook.

There is one oddity.  When scopesink starts up, the vertical scale is at
e+35 !  It takes about two minutes to autorange down to
+/-1000 full scale.  This behavior occurs on both faster and slower Macs.
