SX110IS - howto start porting

Best guess is that the autobuild server is using the wrong keys for encrypting the image.

I also think so, because the Autobuild Server Version was stable. But after some updates the Autobuild Server Version isn`t stable anymore

maybe a new bug:
If I turn on the camera (holding on/off about 2 secs), the lens goes out, but sometimes the cam turns itself off (black screen, and nothing more), and the lens stays out. If I try to turn on-off again, the lens don't goes correctly back, just half way. It is just with the latest version.

which Version Autobuild or latest?
For me this bug was only happen with the "old" (Autobuild) Version when you enable startup sound. But the newest Version fixed this.

the sx110 is not using d3enc, but a whole different key. thats why autobuild fi2 doesnt work.

Thanks a lot chdkj
autofocus is now working 😀

by the way.. instead of SET button.. can i use the Zoom button straightway?

like when i press zoom, it will zoom and auto focus both at the same time?
can zoom button be added in AF key[ ]?

Thanks a lot!

Hmmm, it looks to me that this should be possible. AF keys are hardcoded in gui.c. That means, this is not camera specific code, it is rather CHDK-core code. And therefore I'm not willing to change this code in some SX110-binaries (because we are leaving camera dependent code here).

@Main Developers
What are you thinking about?

Works fine for me. Nice Work! Maybe you're able to add the following feature:
While shooting a video, you press a button wich toggles the AF-assist-beam (or AF-Light -- the red LED in front) on and off. So that you can shoot videos in dark areas (with at least a little bit light)

That's the same as https://chdk.setepontos.com/d/2838/250.

sounds foolish: are you really using the latest version? Battery state? I'm not sure that we are talking about a new bug.
Do you have more information about this?

Are you using the file attached to the post (latest) or the one from the autobuild server? - The autobuild one doesn't work, the attached one(s) does.

If version from autobuild server has a lot of errors, could it be removed (until it becomes stable)?

Puuuh... it was not in my intent to release a new diff before fixing all bugs, but this is more a matter of personal view. You are right.

May I ask you to check in the attached diff (patch file)? It's based on r751.
Changelog
- fixed shooting overrides in capt_seq.c
- fixed optical zoom for record mode in movie_rec.c
- fixed AF scan during movie recording in movie_rec.c
- fixed PT_PlaySound in stubs_entry_2.S
- corrections for SX110 in camera.h
- minor changes in camera specific code (mainly clean up debug stuff and so on)

@PhyrePhoX: do we need a new category like d3enc_v2 or am I wrong?
EDIT: Attachment deleted (final version released on Autobuild already)

No it isn't, look again at the two posts, one is asking for auto-focusing automatically when zooming, one is asking for an option to turn the AF-assist light on (semi-)permanently for shooting in the dark/low light.

Ok, I've to have express myself more precisely. Sorry for that.
AF assist light and AF rescanning while recording is not the same. What I meant is the need for change of CHDK-core code if one wants to use AF-assist light for shooting/recording (as same as for semi-automatically AF scan triggered by zoom lever - btw. a really nice idea...).

I'm thinking about beer. Would be nice. What are you thinking about ? 😉

semi-automatic AF after zoom sounds OK, if you can find a reasonable way to do it. Add it to the bug tracker and submit a patch.

Turning on the AF lamp might be nice, but I'd be slightly concerned that LED is being over driven and is only designed to be on for short periods. It's also not really bright enough to help very much, at least not on any powershot I've used.

@PhyrePhoX: do we need a new category like d3enc_v2 or am I wrong?

It uses the D4 values.

edit:
I've merged chdkj's patch, set the (hopefully) correct FI2 options, the blacklevel and done a couple other minor cleanups. SVN rev 755.

PhyrePhoX

the af lamp is bright enough to be of use in total darkness. this request exists for a long time, you CAN do it via script, but imo it doesnt work on all cams (set_led?). it would be a nice addition. i dont know about reyalps concerns though, as i am a total noob regarding electronics.

BTW, I have such patch for old (Allbest?) CHDK version. If anyone interested, I will upload it tomorrow.

autobuild: sx110is-100b-0.9.8-749-full.zip 2009-04-22
and
chdkj's CHDK-sx110is-100b-0.9.8.zip 2009-04-25

All sounds and startup image are always disabled.

Now I've installed sx110is-100b-0.9.8-755-full.zip. It seems ok.
Thanks to all developers from Hungary!

Several comments:

...

4) Has anyone managed to make any of the motion detection scripts work on the SX110IS?

Nope ??? I tried everything I found from wiki but couldn't get them to work properly.. The "Multipurpose Motion Detection" runs but seems to detect motion everywhere, no matter how I try to calibrate it. 🙁

---

Nice work with the fixes chdkj, I visit this forum daily and every time I can download a version that has something new working 😁

Try fudgey's Fast MD script...

something is out of mesuring with chdk iso.

If i override iso and tell them to go at 15 they go at 25 when taking pictures.

At 40 they are 64
at 100 they are 160
at 200 its 320
at 300 its 500
at 500 its 800
at 600 its 1000
at 700 its still 1000
at 800 its 1250

It does not go above 800

Same things happens if i tweak autoiso . (they do go above 800)

GnF that looks like the difference between canons "Market ISO" and "real ISO"

Damn that is so true. Why does canon reports completly different iso?
