EVALUATION BOARD SOFTWARE
SOFTWARE DESCRIPTION
The AD7797 evaluation board is shipped with a CD-ROM
containing software that can be installed onto a standard PC
to control the AD7797. The software uses the USB of the PC to
communicate with the AD7797, via the cable that accompanies
the board.
The software allows you to configure the AD7797 and to read
conversion data from the AD7797.
Data can be read from the AD7797 and displayed or stored for
later analysis. For further information, see the AD7797 data
sheet available at www.analog.com.
INSTALLING THE SOFTWARE

1.
2.
Start Windows® and insert the CD-ROM.
The installation software should launch automatically. If it

USING THE SOFTWARE
Figure 3 shows the main window that is displayed when the
program starts. The Main Window Options section briefly
describes the various menu and button options on the main
window. The Registers and Other Registers sections describe
the most commonly used evaluation software windows.
The data that has been read can be exported to other packages,
such as MathCAD™ or Microsoft® Excel, for further analysis.
On power-up, the AD7797 evaluation board software configures
the device to have an update rate of 16.7 Hz and the AIN1(−) –
AIN1(−) channel is selected.
At the prompt, select a destination directory, which is
C:\Program Files\Analog Devices\AD7797 by default.
Once the directory is selected, the installation procedure
copies the files into the relevant directories on the hard
drive. The installation program creates a program group
called Analog Devices with the subgroup AD7797 in the
Start menu of the taskbar.
Once the installation procedure is complete, double-click
the AD7797 icon to start the program.
