Dear CHDK people,
first of all, thank you very much for this beatiful piece of software.
I installed it on my SX110, very glad of that, but I'm absolutely unable to do Av bracketing. I was not sure whether to post here or in some beginner area for help, but I decided here because I tried to follow accurately instructions, without result: in contiunous shoot mode I just obtain always the same image. I also tried some script, but no success. Tv bracketing is ok. Apologies in case I'm missing something, or not read with sufficient care the forum  :) .

Does your camera have an iris? It could be that it only has a ND filter, and no real aperture control.

camera.h says it has an iris diaphragm, and no ND filter, so no, that can't be the problem

hth,

Did a quick check: Av bracketing works as good as Tv bracketing does. Please be aware that CHDK will not avoid physical restrictions of the camera. So if you start for instance with an Av of 2,8 (or 4,3 with full tele) and want to lower it by 1 Ev so nothing will happen. You have reached the lower limit already.
Greetings!

hi chdkj,

half press + left key is for AF lock by default (by Canon)
so it isn't a good idea to bind an another function to it (now: disable overrides, before: toggle zebra)

Hi zodiac757,

AF lock still works. In P, Tv, Av, M-Mode you can lock AF with half pressed shoot button + left key if no ALT-mode is choosen. ALT mode + half press shoot button + left key toggles overrides.

It's not published yet.

Use attached version instead, it's the same final version.


EDIT: attachment deleted, use autobuild server instead

@Admins: May I ask to check in the diff? It's based on 813 and checked against current 821.

Thanks for that. I've committed it, svn 822.

One note. You had GetBatteryTemperature commented out in stubs_entry.S. This will not work, because it's an autogenerated file. However, you don't need to do it, because symbols in stubs_entry.S are weak. The new version you put in lib.c will overwrite it, just like NHSTUB in stubs_entry.S.
Don't forget what the H stands for.
