4 Summary

This document provides information about the EVB and Power commander software to allow testing

and evaluation of the DA7322 Audio Codec with DSP.

The hardware solution is based upon two PCBs:

● Digital IO Board - 179-07-D (see References section)

● DA7322 Evaluation board - 196-02-C

Power Commander requires a PC operating Windows 2000/XP/Vista/Windows 7 with a USB

interface.

To run Power Commander under Windows Vista, set the default installation location to ‘C:\Dialog

Semiconductor\’.

Power Commander allows you to:

● Configure the DA7322 using one of the several pre-loaded initialisation files (i.e. start-up

sequences)

● Read and write to all control registers

● Monitor the device status

Note 1 Dialog recommends connecting the EVB+digital IO board to a 500 mA capable USB port as we cannot

guarantee that a USB hub (set to 100 mA) is sufficient to operate it correctly. When using the on board

class D amplifiers, an external supply must be used to provide sufficient power to operate the high

power speaker drivers on the EVB.

5 Hardware

The DA7322 EVB platform consists of two boards that connect together. The first board is the EVB

containing the DA7322 device and essential external components. This board can also be used as a

standalone board or as a module for a customer development platform provided the essential

supplies and inputs are correctly connected to the board.

The second board is the Digital IO board which provides the required power and USB control

interface to the DA7322 EVB to allow signals to be easily connected and configured into the DA7322

device. The digital IO board is referenced in a separate document (UG-179-07-D) which explains the

various connections available and the jumper configurations for the board.
