Audio Spectrum Analyzer: A SuperCon Badge

Description

For the Hackaday SuperConference badge hacking contest, I decided to leverage the hardware provided by Paul Stoffregen's workshop: https://hackaday.io/project/8292-microcontroller-audio-workshop-had-supercon-2015.

The badge has a waterfall audio spectrum analyzer fed by a microphone and an internal sine wave source, a peak detector fed by the same signals, a badge mode to display text, and some image displaying fun.
