Wow that was fast!
Thanks a lot.
will those links will be sufficient for me? i am a noob, first timer with chdk.
I used cardtricks to install the chdk in my card. do i have to place the scripts in the script folder?
is that all i have to do?

Yes and then you have to run the scripts under CHDK

Hi folks,

back from vacation and glad to see the development process. Looks that we will get it soon...

Special thanks to Yarvieh and Obihoernchen for your efforts! Thanks to ewavr for your hints and all other for your time and patience to test the software and given hints.

Cheers!

after some warm words :) to the real world:
- Problems are described in Obihoernchens list http://chdk.setepontos.com/index.php/topic,2838.msg32346.html#msg32346 and in Yarviehs list
http://chdk.setepontos.com/index.php/topic,2838.msg31951.html#msg31951

Does it make sense to put one list "Problems" (or whatever) on the main wiki page for sx110 (http://chdk.wikia.com/wiki/SX110IS)?

- RAW is under development by Yarvieh ? Do you need assistance?

Regarding the math to calculate real sensor size: you have discovered 3720x2772x12. Divided by 8 bit = 15467760 =0xEC04F0. That's exactly that we can find in firmware dump.

- @Obihoernchen: Thats really a good idea to put the sourcecode on the autobuild server. But I couldn't find it there. What did I miss?

I'm going the test the latest version of CHDK for sx110 now.

Regarding the Battery Power...

Would it be useful the distinguish between accumulators (edit: rechargeable batteries) and batteries (edit: disposable batteries)?

Regards.

He Obihoernchen, that's really cooperative work :-). Thank you.

Does anybody work on a diff file for v944+? If not than I will do this in the next couple of days.

Took a first look at the latest version of CHDK for sx110. I know that most people are waiting for a working RAW implementation but for me it was more important to get a more stable software version. Yarvieh has eliminated some bugs, that's great!

Hmmm, I thought that this could be in a more general interest. Ok, anybody could change upper/lower battery values in OSD. But this is a nice feature of a (let us say so) very technical nature. It might be more user friendly to preload some values or to change the calculation depending on the type of battery used. Just an idea...
... and definitely not that important for now...

RAW Support is fine codewise you had no bugs in it. The problem is CAM_COLORMATRIX1 is off so the DNG files the cam exports are not quite in match with reality. I have been working with dave of dcraw to get sx110 support in there and actually with his instructions shot a macbeth colorchart. I have been unable though to get a decent color profile out of dng4ps-2. If anyone else wants to take a shot at it pictures available here.

I Attached the diff against the latest svn rev 744. besides a little bit of messing with the color matrix no other changes.
