A short video showing off my frequency analyzer running on a Tiva C Series Launchpad.

The audio from my laptop goes through a three way splitter, which connects it to the 8x8 LED demo, the 320 x 240 OLED demo, and my speakers. USB is used for power only (no data transfer or getting the host PC to do processing for us. That's cheating :P )

I used http://www.youtube.com/watch?v=qj7dTKhsj3E as the audio source for the 20 Hz to 5 KHz logarithmic frequency sweep, and a portion of "The Fox" by Nickel Creek for the music demo.
