On Linux there are system settings that need to be set to get good performance on GigE cameras.  I have documented them here:

https://areadetector.github.io/master/ADGenICam/ADGenICam.html#linux-usb-and-gige-system-settings

I am not sure if the settings are the same on the Pi.

I haven't done extensive performance tests as yet. The simple tests I have done so far have been to try and achieve reliable performance at 10Hz. To achieve this I've had to use vertical and horizontal binning of 4. With binning of 1 and 2 I get errors like the following:

2020/11/04 21:18:33.203 ADVimba::processFrame error GetReceiveStatus returned 0 frameStatus=-1

I have achieved faster rates but had to reduce the image size further.

I suspect from what limited research I've done that the RPi4's Ethernet interface isn't performing very well.

I haven't tried saving to disk yet. I'm displaying via a Phoebus GUI on a separate Windows system but that doesn't seem to affect the above so far as I can tell.

Hope that helps. If you would like me to run any more specific tests let me know.

Steve

What performance have you been able to obtain with an actual camera?  How many frames/s does it acquire, display in a viewer, and save to disk?

Thanks to all for the replies.

I created a vimbaSupportC/os/linux-arm directory and copied in the relevant files from my AVT Vimba_4_0 download. I also added a linux-arm section to vimbaSupportC/Makefile. ADVimba then built and I have been able to get an IOC working using this.

Hi Steve,

ADVimba does not come with the libVimbaC.so, etc. files for linux-arm.  But those library  files are available from AVT, so you could copy them over and it should build.  If it works we could add them to the distribution.

I get the following error when trying to build ADVimba on a Raspberry Pi. Any suggestions as to how to get around this would be appreciated whilst I continue trying.

Thanks

Steve
