SAMV71 Xplained Ultra Software Package 1.3

SSC with DMA Audio Example

Purpose

This example uses the Synchronous Serial Controller (SSC) of an SAMV7x microcontroller to output an audio stream through the on-board WM8904 CODEC.

Requirements

This package can be used with SAM V71 Xplained Ultra board with external codec WM8904 components.

Description

This program plays a WAV file from PC via Line-In. The audio stream is sent through the SSC interface connected to the on-board WM8904, enabling the sound to be audible using a pair of headphones.

Usage

  1. Build the program and download it inside the SAM V71 Xplained Ultra board. Please refer to the Getting Started with SAM V71 Microcontrollers.pdf

On the computer, open and configure a terminal application (e.g. HyperTerminal on Microsoft Windows) with these settings:

Start the application.

  1. In the terminal window, the following text should appear:
         -- SSC DMA Audio Example xxx --
          -- SAMxxxxx-xx
         -- Compiled: xxx xx xxxx xx:xx:xx --
    
    The user can then choose any of the available options to perform the described action.
