PIC18F 16-bit FFT Real-Time Audio Spectrum Analyser

http://www.waitingforfriday.com/index.php/Real-Time_Audio_Spectrum_Analyser

This project is a real-time audio spectrum analyser based on the PIC18F4550 8-bit microcontroller. It implements a 16-bit FFT with a Nyquist frequency of 10Khz programmed entirely in C. The output is a 128x64 graphical LCD showing 31 frequency buckets from 312Hz to 10Khz.

Complete project details are available on my website in the projects section.
