TIDA-00609

Self-Booting Audio System

TIDA-00609

Design files

Overview

The purpose of this reference design is to provide hardware and software tools that can be used as reference for audio systems. The new revision of the PurePath™ Console Motherboard (Rev F) adds stand-alone self-booting capabilities to allow making compelling demos with any evaluation module (EVM) that is compatible with this platform.

Features
  • Self-booting audio system with push-button user interface powered by MSP430F5510
  • Example MSP430 code and documentation
  • On-board TLV320AIC3262 with miniDSP allows pre-processing of audio signal before sending it over to the DUT EVM
  • Supports USB, optical and analog audio I/Os
  • Modular PurePath console motherboard works with many of our audio EVMs
