TIDM-LPBP-TCHMP3PLAYER
概覽
The audio capacitive touch reference design is a plug-in board for the MSP430 LaunchPad development kit (MSP-EXP430G2). This reference design features several capacitive touch elements including a scroll wheel, button and proximity sensor and nine LEDs that provide instant feedback as users interact with the capacitive touch elements.
The TMS320C5535 DSP and TLV320AIC3204 CODEC also provide MP3 encoding and decoding capabilities. On-board USB, microSD card, OLED display and headset interface round out the design. This features two embedded processors that cooperate and communicate via a UART API/interface between C5535 DSP and MSP430 microcontroller.
