[Discuss-gnuradio] Fft scope frequent hangs

2006-11-16 Thread Matteo Campanella
Hello every1, I haven't been playing with the fft scope for a while until yesterday, when I realized that it frequently hangs on my fc5 with two weeks ago trunk gnuradio... The scope freezes (in all modes) and it needs to be killed to get the control back. No underruns or any messgae that could

I got a Griffin Powermate for testing, as Berndt reports it isn't found by the examples on NetBSD. I suspect we need to abstract out the OS-dependent access and also knob types - this should really be support of generic usbhidev on all systems. I'll see what it takes; NetBSD reads it ok: uhidev0

Hi Eric, In the 'main_loop' of 'usrp_spectrum_sense.py' it says that m.center_freq is the current tunning/tunned freq and that m.data is the mag-squared of the FFT. When I run it I always get: 0 (Zero) as the 'm.center_freq' and some numbers out of the m.data structure (seems ok). Was not 'cente
