<p>
Welcome to using Phidgets with LabVIEW! By using LabVIEW, you will have access to the complete Phidget22 API, including events. We also provide example code in
LabVIEW for all Phidget devices.
</p>
<p>LabVIEW is a development environment for a graphical programming language created by National Instruments.</p>
</div>
</div>
</div>

<div class="phd-slide">
<h2>Requirements</h2>

<p>First, make sure you have the following:</p>

<p>● Phidgets Drivers for Windows installed(see Part 1 of this user guide)</p>

<p>● <span>[https://www.phidgets.com/downloads/phidget22/libraries/any/Phidget22Labview.zip Phidget LabVIEW Library]</span> downloaded</p>

<br />

<p><b>Note:</b> The LabVIEW Library also contains example VI trees, which we'll cover later in this guide.</p>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>One of the best ways to start programming with Phidgets is to use our example code as a guide.</p>

<p>
Unpack the <span>[https://www.phidgets.com/downloads/phidget22/libraries/any/Phidget22Labview.zip Phidget LabVIEW Library]</span> and rename the unpacked folder
to <b>Phidgets</b>.
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Labview_rename.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>Navigate to the following directory:</p>

<p>● For 32-bit LabVIEW, <b>C:/Program Files (x86)/National Instruments/LabVIEW 20xx/instr.lib</b></p>

<p>● For 64-bit LabVIEW, <b>C:/Program Files/National Instruments/LabVIEW 20xx/instr.lib</b></p>

<p>Place the renamed folder at this location:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x250/50/Labview_copy.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>Next, open LabVIEW and create a new VI:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x350/50/Labview_newvi.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>In the new block diagram window, open the functions palette <b>(View -> Functions Palette)</b>.</p>

<p>Next, go to the Phidgets palette <b>(Instrument I/O -> Instrument Drivers -> Phidgets)</b>:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x320/50/Labview_functionspalette.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>Next, select a palette that will work for your Phidget and drag <b>VI Tree.vi</b> onto your block diagram:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x350/50/Labview_vitree.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>Right-click on <b>VI Tree.vi</b> and select Open Front Panel:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x350/50/Labview_openfrontpanel.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>From the front panel, navigate to the block diagram <b>(Window -> Block Diagram)</b>:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x350/50/Labview_showblock.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>
The VI Tree Block Diagram lists all VIs available for its Phidget Class, and which subpalette to find them under. The examples are located near the bottom of
the block diagram. Right-click the example you would like to use and select <b>Open Front Panel</b>:
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x300/50/Labview_runexample.png"></div>
</div>

<div class="phd-slide">
<h2>Using Our Examples</h2>

<p>When you are ready, press <b>Run</b> and the application will demonstrate the Phidget's functionality.</p>

<p>Here is an example of an Accelerometer channel on a Spatial Phidget:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x235/50/Labview_run.png"></div>

<p>
You should now have the example up and running for your device. Play around with the device and experiment with some of the functionality. When you are ready,
the next step is configuring your environment and writing your own code!
</p>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>
First, we recommend enabling the <b>Show constant labels</b> setting in LabVIEW. This setting will reduce complexity when developing, and is especially
recommended for beginners.
</p>

<p>To enable the setting, first navigate to Tools -> Options on your block diagram:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x295/50/Labview_options.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>Select the <b>Environment</b> category and enable <b>Show created constant labels</b> at the bottom:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x350/50/Labview_showconstantlabels.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>To begin working with Phidgets, you will need both a <b>StartPhidget</b> VI and a <b>ClosePhidget</b> VI:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x350/50/Labview_startclose.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>Select a class that will work with your Phidget from the drop-down menu for each VI:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Labview_selectclass.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>
You can now add device information or any initialization parameters to the StartPhidget VI. Using your mouse, hover over each of the connection nodes to see
information about it:
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Labview_hover.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>If you would like to add device information or initialization parameters, right-click the connection node and navigate to one of the following:</p>

<p>● <b>Create -> Constant</b></p>

<p>● <b>Create -> Control</b></p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x260/50/Labview_createcontrol.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>Creating a constant will allow you to modify device information from the block diagram:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Labview_constant.png"></div>
</div>

<div class="phd-slide">
<h2>Configure Your Environment</h2>

<p>Creating a control will allow you to modify device information from the front panel:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x320/50/Labview_control.png"></div>

<p>The environment now has access to Phidgets. Next, we'll walk through writing your own code.</p>
</div>

<div class="phd-slide">
<h2>Write Code</h2>

<p>Along with this guide, your main resources for writing LabVIEW code will be:</p>

<p>● The examples</p>

<p>● The <span>[https://www.phidgets.com/?view=api Phidget22 API]</span></p>

<p>● The VI help files</p>

<p>
Examples of more complex general topics such as using multiple Phidgets and connecting to a Phidget over the Network Server can be found under the VI Tree for
the <b>Phidget Common</b> palette.
</p>
</div>

<div class="phd-slide">
<h2>Example Flow</h2>

<p>Most LabVIEW examples follow the same basic flow: starting a Phidget, reading some data, and closing the Phidget.</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Digital_Input_Example.png"></div>
</div>

<div class="phd-slide">
<h2>Step One: Initialize, Open And Wait For Attachment Of The Phidget</h2>

<p>
The entire process of opening and initializing a Phidget can be done by using the version of <b>StartPhidget.vi</b> that corresponds to your device. In most
cases, <b>StartPhidget.vi</b> will also attempt to wait for the first data to become available from the device for 5 seconds after initialization.
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/StartPhidget_VI.png"></div>

<p>
If you'd prefer to initialize the device manually, you can use <b>OpenPhidget.vi</b> for your device and call the individual functions to set up the device.
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/OpenPhidgetVI.png"></div>
</div>

<div class="phd-slide">
<h2>Step Two: Do Things With The Phidget</h2>

<p>
You can read data and interact with your Phidget both by polling it for its current state (or to set a state), or by catching events that trigger when the data
changes.
</p>

<p>To poll devices, simply place the corresponding blocks:</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x90/50/LabVIEW_polling.png"></div>

<p>
To use events, there are three main blocks for each type, to create, execute, and close the event handler. When creating the event, all devices using an event
of the same type must be grouped into an array to ensure the events get processed correctly.
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/-x100/50/Event_Array_grouping.png"></div>
</div>

<div class="phd-slide">
<h2>Step Two: Do Things With The Phidget</h2>

<p>
Once created, the events will be processed by <b>[Name]EventExe.vi</b>. When an event occurs, the pertinent information will be output, as well as information
to reference which device caused it.
</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Event_Exe.png"></div>

<p>After a program has run its course, the event handler must be closed.</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Event_Close.png"></div>
</div>

<div class="phd-slide">
<h2>Step Three: Close And Delete</h2>

<p>Closing a Phidget is done by using the appropriate version of <b>ClosePhidget.vi</b></p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Close_Phidget_VI.png"></div>

<p>That's all the basic building blocks you need to create a LabVIEW program using Phidgets.</p>
</div>

<div class="phd-slide">
<h2>Help and Documentation</h2>

<p>For more information on the use of any VI and its parameters, right-click the VI and select Help</p>

<div class="phd-lazy-image" data-src="https://www.phidgets.com/decks/PT3_LABVIEW_WIN/Labview_help.png"></div>
</div>

<div class="phd-slide">
<h2>Help and Documentation</h2>

<p>
This will take you to an HTML page outlining the function of the VI. This includes a list of all its parameters, which devices support them, their range of
acceptable values, and their default values, where applicable:
