9 Evaluating with the ADCPro Software

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

ADS1258EVM plug-in is installed as described in the installation section.)

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.

9.1 Using the ADS1258EVM-PDK Plugin

The ADS1258EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS1258. It

consists of a tabbed interface (see Figure 25), with different functions available on different tabs. These

controls are described in this section.

You can adjust the ADS1258EVM 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 ADS1258EVM

plug-in, the setting is immediately updated on the board. If you unload and reload the plug-in, the software

will try to load settings from the board. Settings on the ADS1258EVM correspond to settings described in

the ADS1258 data sheet; see the ADS1258 data sheet for details.

Because the effective data rate of the ADS1258 depends upon settings of the multiplexer mode, clocks,

switch time delay, chopping, and averages, the Effective Data Rate indicator in the upper right corner of

the plug-in interface is always visible and updated whenever a setting that effects the data rate is

changed. In the upper left corner, the Averages control sets the ADS1258 averaging mode. This may be

set to 1, 4, 16, or 64. Note that this is a setting for the ADS1258 device itself; no software averaging is

done in the ADS1258EVM-PDK plug-in.
