MP3 Encoder/Decoder with capacitive touch interface: OLED display & SD card mass storage

Description

The Audio Capacitive Touch design module is a plug in board for the MSP430 LaunchPad development kit (MSP-EXP430G2). This TI Design features several capacitive touch elements including a scroll wheel: button and proximity sensor: 9 LEDs that provide instant feedback as users interact with the capacitive touch elements.The TMS320C5535 DSP and TLV320AIC3204 CODEC also provide MP3 encoding & decoding capabilities. On-board USB: microSD card: OLED display: and headset interface round out the system. This solution features 2 embedded processors that cooperate and communicate via a UART API/interface between the C5535 DSP & MSP430 microcontroller.
