DA7212 Ultra Low Power Codec
and
Power Commander™ GUI Software
Introduction
The DA7212 Evaluation Board has been designed to allow measurement and
evaluation of the DA7212 device.
All Audio Codec functionalities are self-contained within the Evaluation Board
(EVB).
The EVB is supplied with a USB memory stick containing various documents
and a GUI to allow the user to control the DA7212.
The
GUI is called Power Commander™. It uses a simple graphical interface,
allowing the DA7212 to be controlled via a USB port of a PC.
The EVB has a number of jumper links to enable the user to change the
system configuration and to allow him to make appropriate measurements,
although, in reality, few jumper links are required to be altered for standard
operations of the DA7212.
