Good morning
Ha I hadn't seen this answer!

I don't understand the point of putting NI Linux RT online? What's the point ?

I just want to simply deploy my code to this target that has a GPU.
IN fact what I want is to deploy LabVIEW code on my Jetson target.
I don't want to install LabVIEW RT on my target, I just want to deploy my code as if I were on a machine.

Is this possible on an Ubuntu Arm target as was done on Rasberry PI.
The idea is to use the Jetson GPU for HAIBAL deployments.

I asked NI but they didn't answer me.

who could be our contact at NI ?

As i understood, we can install LabVIEW RT everywhere in case to know how to modify the linux kernel source code (open source)
It's possible but it seems it mean to have strong knowledge in OS linux dev.

We will start to work on it to deploy LabVIEW RT on jetson. 
New challenge accepted  

Hi everyone,

Can someone explain to me what this repository is for?

From the NI linux RT source code, can we consider, after hard development work, gateways to, for example, a LabVIEW deployment of RT code on a Jetson nano ?

I would really like to understand what it is, thank you

Hi everyone,

I would like modify a project build specification by using input only the path of the Lvproj.

Is it possible ?

I would like to change with a VI a destination directory of a Build Specification

Thank you for your help 

Good morning

I downloaded the famous state actor patern and clearly it explains absolutely nothing.

Where can I find an example? What's the point ? Does anyone really know? There are no examples anywhere in the NI examples and this VI shows absolutely nothing

How do we launch this switch actor? Where ? I don't understand the point of this VI?

When hitchhiking, is the switch actor useful? (obviously no, since nowhere are the FIFO connections cut, the nesteds are not deleted in the actor who is going to be switched)

OK i'll check 

thank you

It's quite frustrating not to have a direct answer to my question and to be forced to dissect a package to understand.
The simplest thing would have been to explain this override better.
I'll go see but it's really not practical

I really need to understand how it works.

Unfortunatelly there is few information on substitute actor override.

Anyone able to help me ?

Hi  everybody,

I'm trying to use in actor framework the substitute actor override but there is no example on internet. 
Is someone can provide me a simple example to understand it ?

Thank you

It's very simple in fact ... 

Hi,

I'm using .net with LabVIEW and i have some difficulties to open a reference.
I use mscorlib(4.0.0.0) as assembly. (System.io.directory class)

The method i'm testing is EnumerateFile which return a reference representing "an enumerable collection of full file names that meet specified criteria."

Now my problem is to find a method that take this reference and give me back information in readable LabVIEW.

Someone can help me ?

Thank you

Really?
I haven't done any vision application in the last 4 years, but before that I was using IMAQ daily and i never had performance issues with the acquisition part.
And I had a few industrial application that were quite intense in terms of image acquisition and processing.
The processing was also acceptable in terms of perf, except maybe the pattern matching.

Can you describe an application in which IMAQ perf is too low for you?

I phrased it wrong
Vision poses a problem for us because it requires an additional installation. The philosophy of our package is to make it all in one so that it is as simple as possible for our users.
So we want to do without Vision while keeping the same performance.

What also causes us problems is that we don't understand anything about NI on the free, not free, add on... nothing is clear. As a user I do not feel I have to go looking for information, it should be simple which is not the case. (well that's our philosophy)

To do this, we have to do the same thing that the alliance vision team did at the time, a low level switch (pointer).
What we will be able to do in the next few days.

We don't want to use Imaq because the performance are bad for our application.

We would like to use .net with pointer. Anyone knows ?

I guess you don't care about supporting non-windows OSes, right?

For now we are working on windows. In the future we'll work on linux but for now we focus to make it work well on windows.

Finnaly i found the solution to do it 

Now  the next level is to display not the tab but directly a pointer from memory.

Anyone has an idea ?

In fact we would like to compare the image acquisition methods in terms of optimization (display speed).
.net seems to be very interesting.

I posted my Image Manipulation code over on VIPM.IO

https://www.vipm.io/package/hooovahh_image_manipulation/

Here is a video demonstrating some of its functionality, including loading an image into a picture box and manipulating it.

 

I looked at your example and it is really good to start with! 

The problem with .net is the large number of functions, you have to be able to find your way around.

I'm trying to display an image from a table of values on .net and I have not yet found. What method should I use? I have not found a simple example that does it.  😱

Are you asking that in order to avoid NI vision dev module license for your vision product?

If yes, you can install vision acquisition software (> no license for that, at least until 4years ago) and use the image display without needing vdm license

I was not aware about ! I'll test if it's enough.
We already do with our own solution now but we would like to try with other methods because it lacks optimization. 

I also think there is a high potential using .net and i would like to try.
 

Hi everybody,

I'm discovering .net on LabVIEW and i would like simply display a JPG or BMP image. 
Is it possible to have a simple example doing it ?

(I started with Picturebox and imagelocation method but it seems not to be the good method).

Thank you

working now, it was a problem of installation.

strange i test it in another machine it works.

On my principal computer it crash 🤔

silly question : does it work if you don't use a cluster in the dll but independent indicators (2 strings, a float and an int) ?

This example is volontary a cluster for another app. I need a "complexe" structure organized in cluster.

Do you know how to do it ?

Hi everybody,

I'm generating a DLL with this simple function 

I want to recover the clustrer through a DLL function, so i did it in project.

I build the DLL and when i call it, --> TALA CRASH 

To recover my cluster i supposed Type is "Adapt to type" and Data format "Handles by Values"

Of course it's not !

Someone know what are Type and Data format of my output should be ?

Thank you,

(i put the VI and project in attached file

Start is an extension. Remove "start" or enable cmd extensions (/e:on). I'm guessing you think the "/x" is enabling extensions. It's not. There is no "/x".

I have removed start but bat file does not launch why ?
How to launch a bat with LabVIEW cmd ?

I'm trying to launch a batch with LabVIEW but i have some access restriction.

Output of my bat is written in a txt file. 

When i launch it directly in windows it works. When i try with LabVIEW cmd i have some restriction.

Is it possible to make it works with the good cmd ?
