as long as nothing breaks existing code in the other cameras, we can check in your patches. no problem.

@Hyst
Could you explain what is not working, please? Auto-ISO-Shift works as
expected for me: ISO value changes automatically depending on available
light and so on... Am I wrong?

@obihoernchen
http://chdk.wikia.com/wiki/SX110IS#Porting_changelog --> Cool! Thank you.

I am not sure if this is a bug or not.......

I am not using rechargeable battery's but one use. However they seem to finish very very quickly. I managed to take around 60 pictures without flash before battery's run out.

Or i should change something in chdk menu?
Does the cam shut down with your empty batteries or does the camera only show a "dry" battery icon?

all i can do is beta test and my only knowledge is on electricity unfortunately. I can modify my camera to real time measure battery's if that count and report back with info about the state of measures with and without CHDK.

If i can be in any other help please ask me to. I will be more than happy to do it.

decided for me to release new versions of CHDK for SX110 as file
attachments of my posts in this forum.  Of course, that means a lot of
"active reading" to those who want to test a new version. If someone has a
better idea...

For now there is only one active development build as far as I can see.
Yarvieh released a modified version some days ago. I took his modifications
and have them put in my code. So my releases containing his modifications.
Other changes are not known to me. And I will publish my code from time to
time....

Everyone is invited to participate. But someone has to collect all changes
and then release a new official build to the autobuild server.

I could make a website for pre betas. I have enough free webspace^^

From step to step...
A new version of CHDK for SX110!

Optical zoom in video record mode works now.
Please test video bitrate settings.

movie_record_task() in movie_rec.c must call  unlock_optical_zoom()
explicitly because SX110 doesn't support this feature officially (as SX10
does). Therefore no call to unlock_optical_zoom() was necessary in
SX10-code (which I've used as template).
BTW, all camera dependent code related to movie record looks very different
to SX10 so movie_rec.c needs some other modifications. I've changed also the code that deals with video bitrate and quality settings (http://chdk.wikia.com/wiki/SX110IS#Known_bugs). But not tested yet...

That's one of the main problems in this port. SX110 is somehow in beetwen
SX100 and SX10. Some functions have to port like this and other like
that...

Attached is an archive with a new Binary and an other archive with my code (for developers, based on r749).
If video bitrate settings works than I will ask phyrephox to commit a new release to the autobuild server.


Any ideas for "GetBatteryTemperature"?

EDIT: Attachments deleted (final version released on Autobuild already)

What are you thinking: do we have a problem with the battery indicator?

I cannot speak without testing and have to sleep right now. I will do it tomorrow.

It does not seem as a problem with battery indicator (battery read data) since unloading CHDK keeps showing empty battery.

Somehow loading CHDK doubled the power this camera needs? Is this an option? Maybe more things works and thats why this happens?

I will modify my camera tomorrow and test with 4 sets of battery's. 2 sets of rechargeable and 2 sets on one use battery's.
I will test every set with and without CHDK and i will report any findings.
