7. When the firmware download completes, the message box shown in Figure 13 appears. Follow the

on-screen instructions and the plug-in should now connect to the EVM.

8 Evaluating Performance with the ADCPro Software

The evaluation software is based on ADCPro, a program that operates using a variety of plug-ins. (The

ADS7924EVM plug-in is installed as described in the installation section, Section 7.3, Running the

Software and Download of Firmware to MMB3.)

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.

Only one of each kind of plug-in can be loaded at a time. If you select a different plug-in, the previous

plug-in is unloaded.

8.1 Using the ADS7924EVM-PDK Plug-in

The ADS7924EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS7924. It

consists of a tabbed interface (see Figure 8), with different functions available on different tabs. These

controls are described in this section.

At the top of the plug-in is a pull-down menu indicating AVDD. Make sure that the switch S1 on the EVM

matches the setting shown in the menu. This voltage is used in calculating the voltage based on the

output data when using the MultiHistogram tester plug-in.

The data rate is also displayed at the top of the plug-in window. This rate is calculated based on the ADC

Operation mode, the Acq Period and the Power-up Period of PWRCON in the ADC tab of the plug-in. The

AVDD pull-down menu and data rate window are shown in Figure 14.
