General operation of the grabber and artiq_dashboard

ccv

Hi!
I have to questions:

We recently installed a frame grabber module on our Kasli-SoC and are wondering whether there is the possibility to read out full frames from the camera, not just accumulated pixel values at the set ROIs?

Since the artiq_log shows received frame [dimensions], it suggests that full frames are being captured. Is there a way to access this complete frame data (e.g. as a 2D array) in our experiments, or are we misunderstanding how the frame grabber works?

The second question regards the artiq_dashboard. We keep getting an error "QWidget: must construct a QApplication before a QWidget". This was the only error message we got. We already reinstalled PyQt6 but before diving too deep into the source code, we wanted to ask here whether someone has experienced a similar phenomenon. Any suggestions would be appreciated!

Thank you!

How did you install everything?

Do you have a spare camera we could use so we could develop that?

We have both artiq and Pyqt6 installed in an conda environment. PyQt was installed with pip install.

Please don't do that, and install everything with conda instead. That should fix the problem.
