There are multiple hickups here. If you are surre that SFOS doesn't need any special driver, and you can connect generally, then You need to set the GUI right as well.

Script uses Tkinter for GUI. I don't know if usable in SFOS at all. If no (somebody please tell) Then you need to purge the GUI part as well and use it from terminal or cerate a SFOS gui yourself.

Anyway a good coding excecise, but I personally can't say if threre could be any blockers.

I have thr feeling that even if you could connect the Camera to be usable via SFOS, you would need to rewrite py scripts to be used with GUI.
