Grab images using IMAQ without sending frame request

[kcin]

Hello,

When a camera is externally triggered, is it possible to design a *.vi that makes use of IMAQ and grabs images via Camera Link frame grabber without sending frame request signals AND without knowing the external trigger? Just to grab images whenever FVAL, LVAL and DVAL go high. Possible?

Thanks.

Greetings, kcin;

Just to check whether I understood or not, to have the Framegrabber acquire images when the FVAL, LVAL and DVAL lines go high with no other communication between the camera and the host computer? What exactly is the purpose of this endeavor?

Initially, I do not believe it would be possible while using our IMAQ Driver simply due to the way it is designed; I will look into the matter further and inform you of my findings.

Cordially;

Hi Simon,

Just like the camera interfaces on some application processors (e.g. OMAP). Those camera interfaces support image grabbing whenever DVAL, LVAL and FVAL go high.

I am not saying that the host computer must have no communication with the camera, just that the camera is externally  triggered and the host computer has no access to this trigger signal.

One purpose of this is to turn the host computer into a storage device:

[ Camera + Trigger Device ]------------------(CameraLink)----------------[ Host Computer ]

Thanks.

Of course this should be possible... it is done this way when the camera is non-triggered (free-running).

If you just never configure the triggering settings in IMAQ and have the camera configured for its own triggering it should work just fine.
