Hi, I'm new to the forum and I'm looking for help....I'm a beginner in electronics/microcontrollers and have always wanted to build my own Audio Graphic display, using lots of led's, probably 10-bands with 10 led's per band. I've found lots of info and source code on FFT's. I'm using a NEC uPD78F0034 8Mhz microcontroller and just wanted to know about the analogue sampling, how many samples, what resolution I should use etc. will 8Mhz be fast enough to do the sampling and FFT's. Is there any guideline projects already out there.
Thanks in advance,
Joe
