SX110IS - howto start porting

zodiac757

Now I use a smaller card (1 Gb instead of 4 Gb) because above ~200 pictures sometimes I can't turn on the camera.

Hi Zodiac757,

that sounds really strange. I believe there is something wrong with your camera.
Regards!

Are there any updates on future releases for SX110 ?? Is anybody working on it ?
(The last release was on 17th May )

Short answers: No. No.
Long version: CHDK for SX110IS is nearly finished. I'm waiting for a better color matrix to release the final version. The final version will be roughly the same as the version from May 2009. Clearing up some code and modifying some functions and a better color matrix will be built in. There will be no other enhancements! The specific port of SX110 is done since May.
CHDK will be improved in the future and CHDK for SX110 will do so automatically more or less --> but you have to use CHDK from autobuild.
We don't have a working color matrix for RAW/DNG. I'm not capable to produce one.

Greetings.

I asked vit40 about the Colormatrix today... lets hope 😉

Regarding https://chdk.setepontos.com/d/2838/483

I can change to SX100 style controls in the trunk, but not having the camera I cannot confirm this is correct. If someone with the camera wants to test and post a patch, that would be helpful.

Obihoernchen

Yeah good news from vit40!

Look here: https://chdk.setepontos.com/d/3930/6

Lost my motivation, somehow... Other things got more attention... Sorry for late answer.

Thank you. I will submit a patch later.

WTF! I was talking with VIT40 some time ago and now I've missed the hit. Even without any tests: Thank you, vit40!
I will check it next week during one week off...

we are everybody here thinking on your success.
We hope that something can give you some more motivation in this project!

My wife and I just purchased SX110s. I'm really looking forward to trying CHDK on mine. Sounds like it has all the features I'd like to try already, but would be nice to incorporate these latest additions.

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.

whim

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

hth,

...but I'm absolutely unable to do Av bracketing...

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!

After a long period of absence I finally managed CHDK for SX110IS firmware 1.00b.
Summer is gone (here in the northern hemisphere) and I had more time for digging into CHDK last days. It seems to me that no problems left so far. Port is done.

Final version contains:
- Fixed color matrix (based on VIT40's 105-series Standard profile, look at https://chdk.setepontos.com/d/3930/6)
- Battery temperature always shows -99° C (or -146° F). Original firmware function is definitly broken so a fixed unreal value seems to be the best solution.
- Modified shortcut keys:
//Alt mode
#define SHORTCUT_TOGGLE_RAW KEY_ERASE
//Half press shoot button
#define SHORTCUT_TOGGLE_HISTO KEY_UP
#define SHORTCUT_TOGGLE_ZEBRA KEY_DOWN
#define SHORTCUT_TOGGLE_OSD KEY_RIGHT
#define SHORTCUT_DISABLE_OVERRIDES KEY_LEFT
//Alt mode & Manual mode
#define SHORTCUT_SET_INFINITY KEY_UP
#define SHORTCUT_SET_HYPERFOCAL KEY_DOWN
- Some minor code corrections and code clean-up.
- Values für sensor dimensions and active areas corrected in camera.h

Some thoughts about RAW: I prefer DNG but there are some discussions about it in forum. Decide for your own. VIT40 have some interesting hints, look at the post mentioned earlier.
He prepared some color profiles (Adobe Camera Profiles) and I believe it's better to use those than to use the built-in profile (remember: embedded profile is now actually his 105 Standard Profile).
I've learned a lot about color representation of digital cameras during my activities but it's still dimmish for me. I was not able to get satisfied results with DNG4PS but VIT40's camera profiles are working for me.
Don't expect too much, you will get a wide range of results depending on the conditions under which a picture was taken.
I'm definitly not one who you should ask for assistance with color profiles... 😉

Final version will be available from download server as soon as checked in into trunk.
[hr]
CHDK for SX110 will participate from general development of CHDK. But there will be no special development for SX110 presumeably.
I will visit this thread from time to time. Everyone might enhance or fix some things in this port. Feel free!

Special thanks to Obihoernchen, VIT40, Yarvieh and Nomi_68k.

Don't forget: CHDK is free as free in speech and in beer. It's based of the efforts of some people those will earn no money for it. Those people share their knowledge and their work with all of us.
So thank all those guys!

Have fun!

@Admins: May I ask to check in the diff? It's based on 813 and checked against current 821.
EDIT: Attachment deleted (final version released on Autobuild already)

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)

chdkj

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.

zodiac757

thanks for it!
I can't download the new version yet to try it

chdkj

It's not published yet.

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

EDIT: attachment deleted, use autobuild server instead

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.
