Hi Sandeep,

 

Ø  On doing the $(P)$(R)GC_AcquisitionStart.PROC before $(P)$(R)Acquire Start makes the camera streaming on Software Trigger.

Ø  Earlier, I ignored to PROC $(P)$(R)GC_AcquisitionStart and was only relying on $(P)$(R)Acquire to get the thing working.

 

This does not make any sense to me.  When you set $(P)$(R)Acquire to 1 that calls pCamera_->StartContinuousImageAcquisition() in the Vimba SDK:

https://github.com/areaDetector/ADVimba/blob/17dcdb1b0a86db808e200232f8b68d5900c30a8f/vimbaApp/src/ADVimba.cpp#L588

 

It should never be necessary to directly manipulate the $(P)$(R)GC_AcquisitionStart GenICam feature, that is handled by the Vimba SDK.

 

You say you are using “Software Trigger”, but you have not shown us a screen shot of the original ADVimba screen which shows the trigger information, so we can’t tell if you are doing it correctly.  I have attached a screen shot of ADVimba.adl from one of our cameras.

 

I just tested with one of our Allied Vision cameras with ADVimba and I was able to acquire in Software Trigger mode without needing to write to $(P)$(R)GC_AcquisitionStart GenICam.  It is a different model from yours, but I don’t think that should matter.

Hi Mark,

 

Thank you for the suggestions. Its working with passive scan. On doing the $(P)$(R)GC_AcquisitionStart.PROC before $(P)$(R)Acquire Start makes the camera streaming on Software Trigger.

 

Earlier, I ignored to PROC $(P)$(R)GC_AcquisitionStart and was only relying on $(P)$(R)Acquire to get the thing working.

 

Thanks

Sandeep

Hi Sandeep,

 

I get this message on IOC start

2022/11/14 05:13:00.331 Param[ACQ_PERIOD] GenICamFeature::write: node AcquisitionFrameRate is not writable

2022/11/14 05:13:00.359 Param[GC_FRAMERATE_ENABLE] GenICamFeature::write: node AcquisitionFrameRateEnable is not writable

2022/11/14 05:13:00.387 VimbaFeature:writeEnumIndex: ERROR calling SetValue error=-11

 

Those messages are not serious.  They just mean that the camera is not currently in a mode where you are allowed to change AcquisitionFrameRate.  That typically happens because AcquisitionFrameRateAuto is true.  You can ignore them for now.

 

I have 2 suggestions for investigating the problem of the camera not acquiring frames.

 

-          In the upper-right corner of the OPI screen Status rate is set to Passive.  You should set it to 1 second.  Then you will get statistics about dropped frames, underrun frames, etc.  That is important information.

-          The screen you are using appears to be one that you manually edited from the ADVimba.adl that is in the ADVimba distribution.  Please run with the original screen, which has some additional diagnostic information, and send a screen shot of that.

 

Mark

Hello

 

I have Allied Vision Alvium G1-2460m Camera and using ADVimba driver to interface the same. I can write/read all other camera parameters but can't see image streaming (the array counter is not running up). I have followed this link to create template files. I get this message on IOC start

2022/11/14 05:13:00.331 Param[ACQ_PERIOD] GenICamFeature::write: node AcquisitionFrameRate is not writable

2022/11/14 05:13:00.359 Param[GC_FRAMERATE_ENABLE] GenICamFeature::write: node AcquisitionFrameRateEnable is not writable

2022/11/14 05:13:00.387 VimbaFeature:writeEnumIndex: ERROR calling SetValue error=-11

 

The contents of st.cmd are

#   ADVimba driver

#########################

ADVimbaConfig("TEST1-CAM:CAM", 192.168.0.30, 0, 0,0)

dbLoadRecords("/usr/local/epics/support/areaDetector/current/ADVimba/db/vimba.template", "P=TEST1-CAM:,R=cam1:,PORT=TEST1-CAM:CAM")

dbLoadRecords("/usr/local/epics/support/areaDetector/current/ADGenICam/db/AVT_AlviumG1.template", "P=TEST1-CAM:,R=cam1:,PORT=TEST1-CAM:CAM")

 

# standard arrays plugin

NDStdArraysConfigure("TEST1-CAM:Image", 3, 0, "TEST1-CAM:CAM", 0, 0)

FYI, The software trigger source is selected which should capture the frame on every software trigger. Detector state is always in waiting state. I have attached opi screenshot to confirm that camera interface works well. Any suggestions would be appreciated.

 

Thanks

Sandeep
