Good stuff! What frame rate can you get on the LCD display? Your homepage no longer exists - do you have a new URL?

thanks for the download. did you write that yourself or is that from some Microchip application note or from some place else. I need to understand the basics of FFT before jumping into it as i won't know where to begin if i need to modify things in the FFT.
what advice can you give me - what's the best way to go about writing an FFT algorithm ?
also can i stay in touch with you if i have questions ?
