Success: The Raspberry Pi Spectrum Analyzer
This is the RTLSDR based spectrum analyzer ported to raspberry Pi, here shown REMOTELY! via ssh -Y
So latest xforms working, and fftw3, libusb, librtlsdr, rtl_fm, etc all compiled for ARM on debian.
Soon as I get a second HDMI monitor .. as this is too big for the small PAL monitor... But maybe I will compile a small PAL version, after all the little monitor works great. People interested in the source of this spectrum analyzer should ask here.
But remember, getting all libs and permission working took me a couple of hours on a Saturday..
I cheated, I changed the permissions for pi in /etc/pasword to the same as root. Get used to it :-) Time is money, I love this little computah, so far it outperforms my expectations.
