Unable to execute trigger. Aborting...

Hi,

Thanks for the nice tool and the support.

I have followed your previous answers to comment out the configurations, which cameras does not allow. But I faced some other issued which I am not able to understand.

Specs:
Ubuntu 18.04
Spinnaker 2.4.0
Camera: Flir ADK with Ethernet

Terminal output:

I hope the solution is trivial, but I am not seeing it.
Thanks for the help,

@Karthikeyanc2 we use software triggering in this driver to ensure that none of the frames go into the buffer and cause lag. I looks like your camera might not support software triggering. Can you try to create a similar configuration in SpinView and check if it lets you do a software trigger on the camera.

Hi @vik748 ,

Thanks for the quick reply,

Yes, with spinview, it works with the setting: "Trigger source : software"

After you switch to Trigger source software, does the live image from the camera freeze? Does it then take a picture when you click 'Execute' for the software trigger?
Also I noticed your Spinview is 2.3.xx, if you see the README there are known issues with Spinnaker versions above 2.2, can you try one of the tested versions first.

I just tried with spinnaker 2.0.0,

its exactly the same issue,

at spinview, clicking on 'Execute' has no effect. (Also, on whichever trigger source I select and whatever I do with regards to this option, it has no effect, frames are live and does not freeze).

Also, I could not find spinnaker 2.2 in this download website, https://www.flir.eu/products/spinnaker-sdk/. Do you have any other download source?

I believe that once you set the camera to software trigger, it should stop triggering and the image should freeze, even if you high the stop and play button. I don't have a camera with me to try this.
It is possible that this camera doesn't support software triggering. In that case you'd have to modify the code to make it similar to what it does in the MAX_RATE_SAVE mode at

spinnaker_sdk_camera_driver/src/capture.cpp

Line 740 in f6ab290

if (cams[i].is_master()) {

You'd also have to remote the trigger execution line in the main loop.
