New LabVIEW driver standards

Supplier News

THE National Instruments LabVIEW Instrument Driver Advisory Board has released updated standards for the development of certified, plug-and-play LabVIEW instrument drivers, to simplify development of certified LabVIEW instrument drivers.

These standards address the latest technologies and LabVIEW features to help developers easily create quality instrument drivers with a consistent architecture, proper error handling and optimised performance.

The board updated the LabVIEW instrument driver standards to incorporate the latest NI-VISA instrument driver technology, USB capabilities and execution control functions now available in LabVIEW.

In addition, they created an icon glossary that developers can use to easily integrate meaningful, consistent function palette icons into their drivers. This glossary speeds development of instrument drivers while making them easier to use.

To further streamline LabVIEW instrument driver configuration and development, the LabVIEW Instrument Driver Advisory Board also is developing native LabVIEW instrument driver templates for common instruments and custom instrument driver controls.

The templates provide developers with a framework for creating digital multimeter, oscilloscope and function generator drivers that comply with LabVIEW certification guidelines and encourage a standard structure for similar instruments.

The custom instrument driver controls use Merge VI technology in LabVIEW to automatically include appropriate formatting and logic for common instrument driver functionality such as numeric, ring and Booleans controls.

Both of these new tools will be available from the advisory board later this year.

For more information on the latest standards, guidelines and resources for effectively creating instrument drivers, readers can visit the NI Instrument Driver Network at ni.com/idnet.

The industry's largest source for instrument drivers, the Instrument Driver Network features more than 3,000 instrument drivers from more than 170 vendors.
