Audio Codec Board - PROTO is a tool for development of applications with audio playback support. The board includes a  low-power Stereo CODEC WM8731 with an integrated headphone driver.  Connection pads are available for easy connection.

 

Description

The Audio Codec Board - PROTO is a development tool for the WM8731 Audio Codec, ideal for use in embedded applications which require audio playback. The on-board Audio Codec WM8731 provides stereo line and mono microphone level audio inputs. This module also uses stereo 24-bit multi-bit sigma delta ADCs and DACs with oversampling digital interpolation and decimation filters. Stereo audio outputs are buffered for driving headphones from a programmable volume control. Line level outputs are also provided along with anti-thump mute and power up/down circuitry. The device is controlled via 2 or 3 wire serial interface.

Examples

Examples provided with this board will show you how to connect the WM8731 Audio Codec to a microcontroller easily. Each example contains a detailed description and comments of the program. All examples can be downloaded from this page as well.
