Hi!

Here is another release:

* latest chdk v. 0.6.2 (svn rev. 535: / (log) - chdk - Trac)
* hopefully bugfixes Changeset 531 - chdk - Trac "harming machinery"
* fixed zoom point table
* I wrote an encoding tool! No more need to run qemu/gdb to create a bootable image 8)

General usage information should be here SD1100IS - CHDK Wiki . If you have been a newbie and got it to work, please add what is missing!

The attached .tgz file is for end users and contains all files that goes to SD card.
The .bz file is for hackers.

Don't forget to copy CHDK/GAMES/SOKOBAN.LEV to card, otherwise that game doesn't work ;)

As usual: I don't take any warranties. Use at your own risk!

Hi,

I'm also a first-time CHDK user and on my IXUS 80iS it works great. Thank you for your work.
I have a question regarding to scripts. Is it in general possible to overwrite the TV value? I found an interesting script under: BananaKopter - Wiki: MikroKopter.de, created for an IXUS950 Camera. I thought it could work also on my IXUS80, but the Camera ignores all "set_tv96_direct xxx" changes. All images were saved including the shutter speed information from the script but the real shutter speed is different (still automatic). What can I do? I'm not very familiar with scripting.

Thanks
Astro

I'm not sure if I understand you (I didn't look at the script), but if continuous mode bracketing works for you, then it is possible to override Tv in scripts as well.

It's possible that set_tv96_direct must be called this way:
Code: [Select]
press "shoot_half"
do
  P=get_shooting
until P=1
set_tv96_direct 100
press "shoot_full"
release "shoot_full"
release "shoot_half"
instead of this:

Code: [Select]
set_tv96_direct 100
shoot

It all depends on what those commands do and how your camera responds to them in each shooting mode. See for example Digic III propcase 262 in http://chdk.wikia.com/wiki/PropertyCase. It's the "real" or "coming" Tv, and it gets updated at half-shoot. If you set a value to it and then shoot, it will not change exposure. Instead you must change the "user Tv" propcase, but that only has an effect if you are in a manual mode in regard of Tv.

That said, it's possible that your problem may be resolved by adding delays after those set_tv* commands. Start with sleep 500 after each and see how it goes.

There is no zip file at the moment because it's not part of the official CHDK build at this point in time.

See chr's post: SD1100/ixus 80 porting ....

Download chdk_sd1100_e3f0eae_svn-r535.tgz from his post, unpack that. Grab the .bin file that's got 101a in the filename.

Copy that .bin file to your SD card and rename the .bin file to diskboot.bin.

Now lock your card, and insert it into your camera and it should all work from there.

Hi, first thank you so much for this work! I am very happy that i can use chdk with the Ixus 80IS!

After changing  from chdk_sd1100_fdf355c to chdk_sd1100_e3f0eae_svn-r535 i have problems to shoot in RAW-format: the green LED does not stop blinking. Switching to play-modus does not show the picture (but the file is on the card) after shooting again the cam hangs.. (then i have to take out the accu).

After testing and playing a while with MDFB-080914.bas the fileystem on the card was corrupt.

So i changed back to chdk_sd1100_fdf355c, no more problems in raw-modus.

In both versions: after recording videos the window with the bitrate does not close. only switching off and on helps.

Firmware 1.01a, 4 GB card

btw: i hope this is the right place for bug-reports?

bye, Thomas

I can confirm this bug. The raw is written, but the jpg file is missing. That's what should happen while green is blinking.
I'm just wondering why the watchdog doesn't stop that.

edit:
just remember, this chdk contains a bugfix about wrong timestamps of the raw files ... guess there is something wrong.

Mh, the chdk video stuff is not implemented. The options etc. are there but should not have any effect.

Yes and no ... we must find out, if these bugs are only in this port or if other cameras with this chdk version got them, too.

There is a bugtracker now. (My View - CHDK Bugtracker) I tried to get an account but it doesn't let me in. So actually I'm not tracking bugs there.
