Flavors of IVI Drivers

To support all popular programming languages and development environments, IVI drivers provide either an IVI-C or an IVI-COM (Component Object Model) API. Driver developers may provide either or both interfaces, as well as wrapper interfaces optimized for specific development environments.

Although the functionality is the same, IVI-C drivers are optimized for use in ANSI C development environments; IVI-COM drivers are optimized for environments that support the Component Object Model (COM). IVI-C drivers extend the VXIplug&play driver specification and their usage is similar. IVI-COM drivers provide easy access to instrument functionality through methods and properties.

All IVI drivers communicate to the instrument through an I/O Library. Our examples use the Virtual Instrument Software Architecture (VISA), a widely used standard library for communicating with instruments from a personal computer.

Shared Components

To make it easier for you to combine drivers and other software from various vendors, the IVI Foundation members have cooperated to provide common software components, called IVI Shared Components. These components provide services to drivers and driver clients that need to be common to all drivers. For instance, the IVI Configuration Server enables administration of system-wide configuration.

Important! You must install the IVI Shared Components before an IVI driver can be installed.

The IVI Shared Components can be downloaded from vendors’ web sites as well as from the IVI Foundation Web site.

To download and install shared components from the IVI Foundation Web site:

1Go to the IVI Foundation Web site at http://www.ivifoundation.org.

2Locate Shared Components.

3Choose the IVI Shared Components msi file for the Microsoft Windows Installer package or the IVI Shared Components exe for the executable installer.

Download and Install IVI Drivers

After you’ve installed Shared Components, you’re ready to download and install an IVI driver. For most ADEs, the steps to download and install an IVI driver are identical. For the few that require a different process, the relevant chapter in IVI Getting Started Guide provides the information you need.

IVI Drivers are available from your hardware or software vendor’s web site or by linking to them from the IVI Foundation web site.
