LED audio frequency analyzer using Stellaris Launchpad

Posted on Saturday, September 8th, 2012 in LEDs, project logs by the machinegeek


Jordan is a software developer for Texas Instruments Stellaris team. While he’s not working on the Launchpad project, he was able to snag a rev0 board a few months ago, which led to this project. He informs us he’ll be updating his blog with a few other project ideas in the future, and releasing the project code for this frequency analyzer on Github in the near future.
