Labview 2013 Lynx Examples Driver Is Provided

Detailed documentation on the functionality of the Aardvark API can be found in the Aardvark user manual.The Aardvark LabVIEW Driver is provided as a courtesy for Total Phase customers. While it has been verified to be complete and functional, detailed support on the Aardvark LabVIEW driver will not be provided by Total Phase. With that said, any developer familiar with LabVIEW will find that the Aardvark LabVIEW Driver is quite easy to integrate into a LabVIEW design. In addition, the driver can be modified by end-users to create any potential customizations.Main VI Tree showing all the available Aardvark components.

I started by reading the recommended starting point and went through all the examples, templates and hands-on. I have tried a number of times over the last year or so to get my head around the Actor Framework in LabVIEW. Arrays are very powerful to use in LabVIEW.Simple Accelerometer in LabVIEW: This is a basic tutorial on how to connect the a ADLX345 Accelerometer IC (found on the PmodACL) to labVIEW.

READ THIS FIRST to get started with Actor Framework Below is an example/tutorial on how to start from an empty project. I am finally getting an understanding of it and seeing the potential power in using the framework. All the examples that I worked through started with a relatively large project and I could not find an example that starts with an empty project and builds up from there.Last week a colleague explained the basics to me and over the last two weeks I have been working on a large project using the Actor Framework.

Parent Actor: Main Actor which will launch Child Actor Launcher: Main vi which is used to start the program. The introductory level presentation given at NIWeek 20Start off with an empty project and add three virtual folders named, Launcher, Parent Actor and Child Actor.

Actor Framework.lvlib can be found in C:\Program Files (x86)\National Instruments\LabVIEW 2013\vi.lib\ActorFramework\.Create a new Class inside the Child Actor folder and save it.Create virtual folders called Messages and Framework Overrides.Change the inheritance of Child Actor.lvclass to inherit from Actor.lvclass.Create three vi’s that override the Actor Core, Pre Launch Init and Stop Core. This is needed so that the classes we are going to create can inherit from Actor.lvclass. I will explain how to create the Child Actor and then only show the differences in creating the Parent Actor.You need to add Actor Framework.lvlib to your project. The main differences are the way in which they are started.

This is where your Actor’s functionality happens. Actor Core will be the main vi that is run. These vi’s are called before and after Actor Core is launched and stopped respectively.

Unbundle the stop notifier from the Child Actor object Bundle the notifier out into the Child Actor object Use the notifier out terminal to create a control, rename it stop notifier and then move it into Child Actor.lvclass private data cluster. Create a notifier with an empty string for the data type

This is one of many ways that can be used to stop the Actor. This monitors the notifier every 20ms and when it is released in Stop Core, it will stop Actor Core. Unbundle stop notifier from the Child Actor object and wire the notifier into the Get Notifier Status vi On timeout, add a Get Notifier Status and wire the error cluster to the while loop stop terminal

In this case we wire in the Parent Actor class Then Launch the Actor by wiring in which class you want to launch. You first need to create a queue for the Actor Core to be launched on. Create a new vi in the Launcher folder and name it Launcher.vi Make sure that if you want to show the front panel of the Actor being launched, you need to set the Open Actor Core front Panel? To TRUE as the default is false.Creating the Launcher to start the Parent Actor

If not, go back and make sure that you are releasing all the notifiers and queues.Add a Boolean control and indicator to the Parent and Child Actor Core. If this works then we can carry on. When you close the two Actors, they should stop cleanly. The parent Actor will then start the Child Actor. You can make fancy launchers with splash screens, but this one is just a plain vi with an empty front panelYou should now be able to run the launcher which will start the Parent Actor.

Create a new VI from Static Dispatch Template in the Child Class. You also need to add a reference control to the Parent and Child class private data.Make sure you add references to both the Parent and Child Classes.We now need to create a method (vi) in the Child Class that is going to change the Child indicator when told to do so. We will use these references to get and update their state from other vi’s with the class. This will show the basics of sending messages between Actors.You need to add references to both Actors for their respective indicators.

There are some tools that allow us to create these messages really easily.From the project window, select Options and then Actor Framework Message Maker. We now need a way to be able to run this vi from the Parent Actor. In the block diagram, unbundle the indicator reference, wire it into a property node and then write the Boolean state to the value property.This vi is the method that does the work of changing the Child Actor front panel indicator.

I am not going to go into the details of these vi’s but feel free to open them and see what is going on.Now that we have our Message and our method, we need to go back to the Parent Actor and to define when to execute this message.In the Parent Actor Core, add an event case to handle a value change from the Boolean control. Close the vi’s and move the class to the Messages folder within the Child Actor.The Send Get state from Parent vi is used to add the data to a queue and the Do vi calls the method that we created a step back. Select the method that we just created and click Build Selected.A Get state from Parent Msg.lvclass is created with two vi’s.

Notice that changing the control on the Parent Actor, changes the indicator of the Child Actor.Now repeat the process to send the state from the Child Actor up to the Parent Actor. This will then update the front panel indicator of the Child Actor.Save your project and run the Launcher vi. The Do vi will then be called which will then run the method from within the Child Actor Class. This will put the Boolean control state onto the queue of the Child Actor. Add the Set Get state from Parent vi to the event case.

The main program of an Actor is the Actor Core that is overridden from the base class Save the project and it should now workThe final project should like something like this.You are now able to send states both ways between the Parent and Child Actor.I used these points to get a better understanding on how the Actor Framework works: You now need to get the caller enqueuer and wire that queue in. Wire the control into the Send Get state from Child vi Add an event case to the Child Actor to handle the state change Create the messages using the Actor Framework Message Maker tool

I still have a way to go but am getting there and the more I use it, the more confident I am getting. To speak to a specific Actor, create a message and tell it which queue to execute onIt took me a week or so to get my head around what goes on. Think of each Actor as its own process with a queue. Use Read Callers Enqueuer vi to get the queue of the Actor that Launched it Use the Read Self Enqueuer vi to get an Actors own queue

I hope I have made the most important steps clear enough.
