ADS7040EVM-PDK Kit Operation

This section describes how to use ADS7040EVM-PDK and the ADS7040EVM software to configure the
EVM and acquire data.

6.1

About the SCC Controller Board

The SCC controller board provides the USB interface between the PC and the ADS7040. The controller
board is designed around the AM335x processor, a USB 2.0 high-speed capability, 32-bit ARM core. The
SCC controller board incorporates an onboard FPGA subsystem and 256MB of onboard DDR SRAM
memory. The SCC controller board is not sold as a development board, and it is not available separately.
TI cannot offer support for the SCC controller` board except as part of this EVM kit.

6.2

Loading the ADS7040EVM Software

The ADS7040 EVM software provides the ability to capture and analyze data from the ADS7040.

To load the ADS7040 EVM software, follow these steps:

Step 1.

Make sure the EVM kit is configured and powered up as explained in

Section 5

.

Step 2.

Start the ADS7040 EVM software. Go to Start

All Programs

Texas Instruments

ADS7040 EVM and click ADS7040 EVM to run the software.

Step 3.

Verify that the software detects the ADS7040. The GUI identifies the EVM hardware that is
connected to the controller board and displays the

ADS7040EVM Front Page

. After the

settings are loaded,

ADS7040EVM GUI

is displayed at the top of the GUI screen, which the

device identified indicated at the right hand top corner as shown in

Figure 13
