ADS794xEVM and ADS794xEVM-PDK
7 ADS794xEVM-PDK Kit Operation
The evaluation software is based on ADCPro. This program operates using a variety of plug-ins. To use
ADCPro, load an EVM plug-in and a test plug-in. To load an EVM plug-in, select it from the
EVM menu.
To load a test plug-in, select it from the Test menu. To unload a plug-in, select the Unload option from the
corresponding menu.
The following sections describe how to use ADCPro and the ADS794xEVM plug-in to acquire data.
7.1 About the MMB0
The MMB0 provides the USB interface between the PC and the ADS794xEVM. The MMB0 is a modular
EVM system motherboard. It is designed around the
TMS320VC5507 , a DSP with an onboard USB
interface from Texas Instruments. The MMB0 also has 16 MB of SDRAM installed.
The MMB0 is not sold as a DSP development board, and it is not available separately. TI cannot offer
support for the MMB0 except as part of an EVM kit. For schematics or other information about the MMB0,
contact Texas Instruments.
7.2 Loading the ADS794xEVM-PDK Plug-in
The ADS794xEVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS794x.
You can adjust the ADS794xEVM settings when you are not acquiring data. During acquisition, all controls
are disabled and settings may not be changed.
When you change a setting on the ADS794xEVM plug-in, the setting immediately updates on the board.
Settings on the ADS794xEVM correspond to settings described in the ADS794x product data sheet
(available for download at http://www.ti.com ); see the product data sheet for details.
To load the ADS794xEVM plug-in, follow these steps.
Step 1. Make sure the PDK kit is configured and powered up as explained in Section 6.3 and
Section 6.4 . Then, press the Reset button on the MMB0 (in the top right-hand corner) once to
clear the board memory.
Step 2. Start ADCPro from the Windows Start menu.
Step 3. Load the ADS794xEVM plug-in from the ADCPro drop-down EVM menu; see Figure 10 . Note
that only one EVM plug-in can be loaded at a time. If a different plug-in is selected, the
previous plug-in is unloaded.
Step 4. When the plug-in is loaded, the plug-in searches for the board. A series of messages in the
status area will indicate this action, eventually showing
Select Device...
The plug-in is now loaded and ready to work with the ADS794xEVM.
