Frequency Analyzer Overview

A long time ago, in the way back when, I ran soundboards on a regular basis.  I did this enough to build up a decent knowledge base for audio systems, so when I first started getting into hobbyist micro-controller projects, anything involving audio was immediately attractive to me.  As such, the first two projects I did were frequency analyzers that made use of Texas Instruments’ Stellaris Launchpad Platform.  Here, you can find writeups for my 8×8 LED array and 320×240 OLED frequency analyzers.  The source code for these and the Eagle schematics and layout files are all accessible on my github.
