AMC7834EVM Software Setup

This section provides the procedure for EVM software installation.

3.1

Operating Systems for AMC7834EVM Software

The EVM software was tested on the Microsoft

®

Windows

®

XP and Windows 7 operating systems with the

United States and European regional settings. The software should also be compatible with other
Windows operating systems.

3.2

AMC7834EVM Software Installation

The software is available through the EVM product folder on the TI website. After the software is
downloaded on the PC, navigate to the AMC7834EVM_Installer folder, and run the setup.exe file, as
shown in

. When the software is launched, an installation dialog opens and prompts the user to

select an installation directory. If left unchanged, the software location defaults to C:\Program Files
(x86)\AMC7834EVM. The software installation automatically copies the required drivers for the SDM-USB-
DIG and AMC7834EVM to the PC. After the software is installed, connecting the SDM-USB-DIG to a USB
port may launch a driver installation dialog. Choose the

‘Install this driver software anyway’

option to

continue with installation. (Note: On Windows XP machines, choose to have the system automatically find
the driver or software.)
