DA7210/11 USER MANUAL
Evaluation Board Features

3.1 USB Interface
The USB Interface is used here for the following purposes:
As a source of I2C and SPI control signals.
To provide a discrete signal to the power down pin PD (DA7210 only).
To provide level shifting voltages.
To allow standalone operation of the evaluation board using the +5V
only.
The USB control signal device is powered by the USB bus cable via a fixed +3.3V
The USB interface control signals can be isolated from rest of the evaluation board by removing J51,
J53 and J55 described in Table 1. Removing these jumpers will allow external signal access to the
DA7210 control interface. The USB interface can also be used to supply the power supplies to the
DUT on the evaluation board.
The USB Interface implements multi-mastering on its I2C interface, permitting concurrent operation
with any other multi-mastering controller. This allows the software to control a DA7210/11 device
which is already part of the users system, and under control of the system processor.
4 Control Software
4.1 Installation
Insert the DVD-ROM containing the software into the controlling PC. If the installation does not start
automatically, run the program 'setup.exe' from the DVD-ROM containing the software. An automated
script will install the program to your PC. By default, the directory 'C:\ProgramFiles\Dialog
Semiconductor\Audio\DA7210 Rev x.x' will be used.
As Windows Vista imposes limitiations on the 'C:\Program Files' directory, change this default to
'C:\Dialog Semiconductor\Audio\DA7210 Rev x.x' when prompted.
Plug in the USB cable, and Windows will detect the USB device. It will prompt for the drivers, which
should be automatically located on the root directory of the DVD-ROM. The setup file is ''dlgezusb.inf'
and the following description explains how to install the driver.
