Digital Delay Demo for the ADSP-2181 EZ-Kit Lite (EE-93)
Implementation guide for a digital delay demo on the ADSP-2181 EZ-Kit Lite. Describes circular buffer configuration and source code modifications for the AD1847 codec.
Overview
This technical note (EE-93) provides instructions for implementing a digital delay demonstration on the ADSP-2181 EZ-Kit Lite development board. Using the AD1847 codec for A/D and D/A conversion, the document details how to modify the 'MIC2OUT' sample application. It explains the declaration and initialization of circular buffers in data memory to store audio samples, the use of interrupt service routines for real-time processing, and methods for adjusting delay length based on the 8 Ksps sampling rate.
Use Cases
- Audio signal processing development
- Learning DSP programming fundamentals
- Implementing real-time audio effects
- Evaluating ADSP-2181 hardware capabilities
