EV6550DHAT Raspberry Pi HAT for CMX655D
UM6550DHAT/1 November 2019
USER MANUAL
Provisional Information
Features Demonstrates CMX655D functionality Two digital top-ported MEMS microphones Easy screw connection for external speaker Flexibility to use local or off-board power for the PA Accessible GPIO and test pads to allow further options (e.g. external MEMS) User modifiable prototype space Option to add line out phono connector Simple GUI interface with open-sourced drivers Conforms to the HAT definition 1 Introduction
The EV6550DHAT brings together the Raspberry Pi and the CMX655D Ultra-low Power Voice Codec in a convenient way, enabling easy demonstration of the CMX655D and providing improved low power audio capabilities to the Raspberry Pi. This is achieved using common hardware and open-source software, simplifying its use and simplifying software and hardware development.
2 CMX655D Ultra-low Power Voice Codec
The CML CMX655D Ultra-low Power Voice Codec integrates two matched channels supporting a large variety of digital MEMS (Micro-Electromechanical System) microphones and signal processing capability along with a 1 Watt high efficiency Class D speaker amplifier. As an inherently low power codec it is ideal for use in low power projects and developments typically based on the Raspberry Pi. 2019 CML Microsystems Plc Document Outline User Manual Front Page 1 Introduction 2 CMX655D Ultra-low Power Voice Codec 3 Raspberry Pi Compatibility 4 Power Supplies 5 Handling Precautions 6 Quick Start 6.1 Mounting The EV6550DHAT To The Raspberry Pi 6.2 Software Installation 6.3 GUI Description and Board Operation 7 Supplied Source Code 8 GUI ‘C’ Source Files and Modification 9 Troubleshooting 10 Additional Hardware Information 10.1 Hardware Test Points End of Document
