Using Pickering Drivers in LabVIEW
Most Pickering drivers include a LabVIEW wrapper to permit full operation of the Pickering product from the LabVIEW environment. These wrappers are normally installed to the current LabVIEW folder system during installation of the Pickering driver.
The process of controlling a Pickering product normally consists of the following steps:
- Open a control session on the product
- Use functions in the library to operate the product
- Close the control session
In the case of LXI products there is an additional step to establish a communication session on the remote LXI device prior to opening the control session on the hardware. This communication session should also be terminated when no longer requiredThe LabVIEW libraries are wrappers of the underlying low level driver and full details of the functions can be found in the corresponding low level driver documentation.
Following are simple examples of the use of the most common Pickering drivers. These examples may be downloaded by clicking on the link next to the diagram.
In all examples, the program opens a card, obtains it's card identity, operates a single switch and then closes the card.
