Internally Triggering a Labview camera capture (Hamamatsu ORCA) by external instrument (Metrohm Autolab, NOVA software)

[dr227]

Hi all, 

I have just started with Labview and sorted out  capturing frames using Hamamatsu ORCA camera. I am looking to implement internal (software /without external cable) triggering the frame capture by a trigger from an external instrument (Metrohm Autolab) which has a .NET functionality. Properties available from Autolab is given in the attachment along with a simple example code to take a snap. 

I am looking for help and guidance to set up the .NET in the Labview and the required setting in Autolab software so that the trigger frpm Autolab application can send a software trigger to the vi. 

I need help specifically in passing the trigger. Many thanks.

1) Your VI as provided is kind of useless, as it only calls a series of sub-VIs, all of which are not included.

2) Are you already able to detect the trigger from Autolab, or is this precisely the portion you are trying to implement? As I understand, you're looking to receive a trigger from Autolab in order to start your acquisition in LabVIEW, is that correct?

Thank you Intaris.

From point 2 of your message - I am trying to detect the trigger from Autolab in my vi. 

The vi is just an example - you can treat it as any simple function.

OK, and the "call .NET" is the method you're looking at utilising to achieve this?

I'll have to defer to others for that, I've not got enough .NET experience to give any meaningful input aside from the fact that if there isn't some in-built .NET function you're looking for, you'll have to write a .NET wrapper function to bridge the gap between the two pieces of software. It may not be a purely LabVIEW implementation.

My follow-up question is whether this "Trigger" you refer to already exists, or if you're trying to create a software trigger... I'm assuming there's the ability to create a "script" in the Autolab software, via which you're trying to create a link to your LV code, right? This "Trigger" is what you're trying to create, is that correct?

Thanks again. We can generate the trigger form the Autolab software. The labview application needs to pick that up. I have never used the .NET functionality in labview. Any pointer or code for the wrapper would be of great help.

In order to be able to understand how to get that "trigger" into LabVIEW, it's important to understand what the "Trigger" IS.

You say you can generate a trigger, but what form does this trigger in the Autolab software take? Analog, Internal, what?

[dr227]

Hello,

This particular arrangement will be internal trigger. I believe the trigger can be in or out. However, we certainly need the tigger in (internal/software) to the vi for the camera. Once the snap is completed, the vi should send a trigger back to the Autolab.

Can you show where the trigger is generated so that there's some context on what you're trying to integrate?
