AM275 FreeRTOS SDK  11.01.00
AASRC Stereo Playback

Introduction

This example demonstrates the AASRC configured for STEREO operating mode. AASRC takes the digital audio data streams received using McASP at 48 kHz FSYNC rate and converts the same to 96 kHz and send out the converted data as audio out using McASP. McASP FSYNC clocks is being used as the reference clock for AASRC receive and transmit. Audio can be inputed from the 3.5mm audio line in jack (J2 Top) and audio out can be heard from audio line out jack (J3 Top).

  • AASRC & McASP is configured in 24 bit data format
