Overview
This example VI shows how to use the USB Interrupt Pipe utilizing LabVIEW VISA commands.


Description 

This example VI shows how to use the USB Interrupt Pipe utilizing LabVIEW VISA commands. You must have a VISA Driver for your device and the RAW USB device must show up in Measurement and Automation Explorer. The example VI will then be able to work if the device supports an Interrupt Pipe.

Requirements

Software

  1. LabVIEW 2012 or later
  2. NI-VISA Driver

Hardware

  1. RAW USB Device

 

Steps to Implement or Execute Code

  1. Choose correct USB RAW VISA resource name.
  2. Set Timeout to wait for Interrupt (ms).
  3. Run the VI.

 

NOTE: You must first get your interrupt pipe USB device recognized by Windows and attach VISA to it as a driver using the VISA Driver Development Wizard. The USB RAW name should show up in MAX, and you should be able to select it below.  Running this VI will cause the VI to wait for an interrupt from the device and then return the interrupt data once it occurs.
