I have two sx280IS cameras and want to get ultimate.lua working.
Try the attached modification of the 4.8 script.
It hopefully eliminates a crash that the original 4.8 would cause on most or all newer cameras (IS_MODE propcase related). It also fixes the on-screen status display, so that it can be read.
Flickering is most likely caused by something that updates the Canon OSD. For example, face recognition or maybe continuous focus. Avoid using AUTO modes, try P, Av or similar.

edit:
Camera restart is not functional on DIGIC 6 or newer cameras, don't use that script functionality.
edit2:
DIGIC version check fixed

Thanks very much. The script you sent seems to be working well. I put the camera in AV mode. My camera had the "Review image after shooting" set to hold and this caused problems. Setting it to off (also 2sec) fixed it. (I realize this probably was why the ultimate.lua was only giving the first shot) I set the camera to reset after 365 days (to prevent it from resetting).

Are there other scripts specially fixed for the sx280?
Is there anything I can do to help eg document how to use these scripts on the sx280.
Cheers, Bill

edit 1: It still churns thru the battery. I've got a power adaptor on order from china.
edit 2: I just compared your new code with the one I was having problems. I realize my main problem was the camera "Review image after shooting" being set to hold :-[

I don't know, but we prefer to fix the ports rather than having per-camera fixes in scripts, if possible.

Sure, anything that might help others. Or, if you find things that look like bugs.

As for the review related problem, that's a CHDK shortcoming - different camera generations handle the review setting differently and there is no generic method for a script to detect it.

thanks,
I had not noticed problems running Ultimate Intervalometer 4.8 with IS_MODE=3 on my digic6 M10 and I thought it was because 3 was not defined.

First thing I do with time lapse cameras is set IS to OFF in Canon Firmware, so I never gave it any thought.
But I've updated SUIx with your suggestion.
