jim hamblen / Mbed 2 deprecated AppBoard_Waveplayer

A wave player demo setup for the mbed application board. Reads a wave file from a USB flash drive, and outputs to the onboard speaker (very low volume) and the analog audio out jack that can be connected to a set of PC speakers for more volume. A wave file for the demo is available at http://mbed.org/media/uploads/4180_1/sample.wav. Copy it to the USB drive. See http://mbed.org/users/4180_1/notebook/application-board-waveplayer-demo/ for more details and instructions.
