yet another spectrum analyzer although not so spectrum... running on 1mhz atmega8 pb0-4 as data port for LCD pd6-7 as control lines audio input at adc5 this is kind of excersise in avr assembler - my first code in avr asm so far...

Aug 3, 2008 - nope, just looks nice now i'm woriking on true fft on atmega32 - just because i wanted to use graphical lcd, and atmega32 has more pins

Aug 11, 2008 - what is actually the best way to implement fft? i've been searching for some good articles for a long time. can you perhaps provide something useful?

Aug 16, 2008 - on what system do you want to implement a fft? on an avr?? there is plenty of stuff on the web - the fft written by elm chang is quite popular... if you consider to use an atmega8 you can get also my version of a fft ;)) greetz zero

Aug 17, 2008 - radix-2 algorithm should fit nice beside - thare are some readly avialivable ones on web, as good poit to start thinking about your own

Jul 24, 2008 - hey looks pretty cool :) but it isnt a real fft, right!? so how do you generate the different bars - 'fitting' to the signal input?? greetz :P
