Hiya, I've committed some (seemingly) working spectral scan code to FreeBSD-HEAD. This includes the relevant radar register frobbing to get HT40 scan results. Take a look at sys/dev/ath/ath_hal/ar5416/ar5416_spectral.c . I'm just hacking on your FFT code now (and likely my QT based plotting code) to plot out live data. Your fft_eval program doesn't really like some of my spectral dumps (30,000 + entries :-) Adrian -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
