EVALUATION BOARD SOFTWARE

The

EVAL-ADE7903EBZ

evaluation board is supported by

Windows®-based software that allows the user to access all the
functionality of the

ADE7903

The software communicates with the SDP-B Blackfin board
using the USB. The microcontroller communicates with the

ADE7903

ADC on the evaluation board to process the requests

sent from the PC.

INSTALLING THE DRIVERS

When using the

ADE7903

evaluation tools for the first time, a

driver must be installed to allow successful communication.
The driver

SDPDriversNET.exe

can be found in the evaluation

software package in the

SDP drivers

folder.

To install the driver, follow this procedure:

When the Setup Wizard appears, click

Next

, and follow the

installation instructions.

Figure 10. SDP Drivers Setup

When the installation is complete, click

Finish

to close the

window.

Connect the USB cable from the PC to the SDP-B Blackfin
board. Windows detects the device and locates the correct
driver automatically.

INSTALLING AND UNINSTALLING THE

ADE7903

EVALUATION SOFTWARE

The

ADE7903

evaluation software is supplied with the

evaluation software package. It contains the LabVIEW-based
program that runs on the PC. This program must be installed.

Before using the evaluation software on the PC for the first time,
run the installer. This installer is available in the

installation_files

folder. If a copy of LabVIEW 2010 is available on the PC, the
executable is provided in the

executable

folder. The LabVIEW

source files are provided in the

LabView_project\source

folder.

To install the ADE7903 evaluation software, double-click

installation_files\setup.exe

to launch the setup program

that automatically installs all the software components,
including the uninstall program, and creates the required
directories.

To launch the software, go to

Start

Evaluation Software

Both the

ADE7903

evaluation software program and the NI

run-time engine can be uninstalled using the

Programs

option in Control Panel.

Before installing a new version of the

ADE7903

evaluation

software, first uninstall the previous version.

From the Windows Control Panel, click
