Example Code

Description

Overview

This document has been archived and is no longer updated by National Instruments.

This is a consolidated export of legacy NI-DAQmx shipping examples that were included in LabVIEW 2011 and earlier. Newer versions of LabVIEW and NI-DAQmx install a revised set of shipping examples that can be reviewed here.

The examples on this page are the same examples that are installed on your machine when a compatible version of NI-DAQmx is installed with LabVIEW 2011 or earlier. These coding examples demonstrate basic analog, digital, and counter acquisition and generation, plus other concepts like synchronization. Use this page to locate your local copies of the examples, replace your existing files, review older examples, or search through extended example descriptions to locate an example to meet your needs. Additionally, you may find these shipping examples referenced in some older content.

Many other coding examples demonstrating extended and unique functionality submitted by NI and community members for NI-DAQmx and other products are available at http://www.ni.com/examples.

Introduction

The legacy NI-DAQmx shipping examples on this page were included from LabVIEW 8.5 through LabVIEW 2011. NI-DAQmx 9.5.5 launched with LabVIEW 2012 and introduced a more consolidated set of shipping examples with new user interfaces based on LabVIEW silver controls. In addition to these examples being included with older versions of the NI-DAQmx drive and LabVIEW, they were also previously posted to the online NI Community in an effort to be more searchable and assist users in replacing modified examples with new. Additionally, the examples on this page allows users of newer versions of LabVIEW and NI-DAQmx to use the legacy examples if they prefer.  

• You can also access the NI-DAQmx shipping examples that are currently included with newer versions of NI-DAQmx and LabVIEW.

Finding the NI-DAQmx Shipping Examples Already Installed on your System

If you've installed a compatible version of NI-DAQmx and with LabVIEW 8.5 through LabVIEW 2011, then you should already have these examples installed, and can locate them without the need to download from this article unless you'd like to further search through them, or replace existing modified examples. 

To check the version of NI-DAQmx and LabVIEW installed on your system, reference KnowledgeBase 4W1GE4NC. Also, you must install NI-DAQmx with ADE Support to get the LabVIEW API and the examples. Installing NI-DAQmx variants such Core, Run-Time or Configuration Support will not install the LabVIEW API, or the examples per KnowledgeBase 619L79ZK. Also note these NI-DAQmx examples are different than those that ship with NI-DAQmx Base, which is a subset of NI-DAQmx for advanced users.

• The preferred method of accessing NI-DAQmx LabVIEW shipping examples is from the LabVIEW welcome splash screen, or from any front panel or block diagram by selecting Help » Find Examples » Hardware Input and Output » DAQmx and then browsing the sub-categories. Note that descriptions and compatible hardware for each example is also provided when browsing this way.
• You can also locate your LabVIEW shipping examples on disk by navigating to the default install location at:
  <Program Files>\National Instruments\<LabVIEW>\examples\DAQmx .

Opening the Attached Files

The attachment on the right side of this page includes a folder for each of the NI Community HTML pages that described each example as well as how to run them. Each folder also contains the example VI's, and any other resources referenced. Once your download is complete, you can extract the files and then browse or search locally for examples. 

The HTML file originally posted with the example code is provided as a reference with most NI community formatting removed. The HTML file contains a description of the functionality, how to use the code and a VI snippet to quickly review the code. Links contained within the HTML files may not be valid. Instead, use the files contained in this export. Some files may need to be unzipped before using. Note the embedded images and style sheets are stored locally in the 'resources' folder.

Some examples may be able to be downconverted to previous versions of LabVIEW, but this conversion is not NI supported or guaranteed to work. All examples on this page compatible with being upconverted to a newer version of LabVIEW.

Searching The Attached Examples for Your Application Needs

In addition to browsing your examples, you can also use Windows search. To find examples relevant to your needs use keywords the same way you would when searching on the web. Windows search can search through the folder and file names, as well as the content inside the HTML file.

Downloading LabVIEW or NI-DAQmx, and Understanding Compatibility

LabVIEW 8.5 or newer is required to run these examples, as well as a compatible version of NI-DAQmx. Note that LabVIEW 2012 and newer will open these examples, as well.

• Download current or previous versions of LabVIEW. 
• Download current or previous versions of the NI-DAQmx driver.
  • Note NI-DAQmx Run-time, Core or Configuration Support will not install LabVIEW API support. NI-DAQmx Base only offers advanced functionality not compatible with these examples.
• DAQmx and LabVIEW Version Compatibility
• How to Upgrade or Revert a VI to a Different Version of LabVIEW

File Extraction/Copy Errors

If you receive a Windows error similar to 'Destination Path Too Long' or 'The file name(s) would be too long for the destination folder' when trying to extract or move this archive, you will need to move your directories folder levels up to create a shorter overall file path. Folder and file names are based off example titles, with some being long.
