CHDK for PowerShot SD770 IS/DIGITAL IXUS 85 IS: Update: Pg2 RAW in 12bit

Hi.

I've finished a complete port to IXUS85 / SD770IS 100a, based on IXUS970 100b port. The version is 0.9.8.

Almost everything is working fine:
- movie override (at least it seems to be changing the quality!)
- RAW / DNG is OK
- all the CHDK tasks

Because it is based on IXUS970, the shutter_speeds_table is the same (I don't realized how to fill / update this table).

I'm not familiar with "firmware update method", so I didn't worked on this.

It would be great to see if this port works ok on someone else's camera, because it is my first time/post/port 😛

Cheers!
Pedro

Nice work pedropaislopes!

Please upload your source somewhere, so the work isn't lost like the original port.

edit: add full quote since this ended up on a new page.

I have some of the same problems with this version as the previous development snapshot.

Before, when enabled, sometimes instead of taking a picture, the entire camera would just shut down.

Now, when I use Bracketing in continuous mode, the camera take one or two pictures and then just stops.

Great to have someone working on this again!

Thanks for your efforts.

Glad to see that another SD770 camera is working with this binary (at least taking some shoots)!

I'm facing the same problem. Continuous shooting is not working. Maybe it is related with stubs_entry.S stuff (I didn't reviewed all the functions, btw).

I'll work on this on the next days. And I'm posting the source code as soon as I can.

Cheers

Thanks for fine work, long waited for this moment. Has put on the ixus 85 together with additional files for Digital IXUS80 (the version 1.01B) - all works correctly: raw forms, video parametres vary. It is possible to hope for fast appearance of the final version?

Really really cool. Hope to find it soon in autobuild. That would be a wonderful Christmas gift.
Good work fellows.

Hi.

After a some delay (sorry!), here is the source code. It is based on a newer svn download (I've made the download yesterday), so it is version 0.9.9.

All the files that I've changed are on the archive, on the right place. Any problem with .tar.gz file structure please let me now.

The problem related with continuous shooting continues. It crashes the camera, and my idea is that the problem are on capt_seq.c file (the hooks to do NR stuff, I suspect).

I will not have access to the camera for a month, so I can't help with this problem in the next weeks.

Cheers!

And with version 0.9.9 all works (except serial shooting, certainly). By the way, video is written now and with maximum quality (on the previous version the device was switched off).
Thanks!

Hi.

I've corrected two typos on the functions related to continuous shooting. Because I don't have access to the camera, anyone could test if it fix the crash?

And please test if the extra long exposure works too.

Cheers!

I tried it, if I take a normal picture with the standard options it just shuts off. Continuous shooting doesn't seem to work to well with me either. I have no problems with the previous version except for the continuous shooting which shuts the camera off.

I've tried a few scripts on the previous release, they work good but I haven't found a good bracketing script for HDR pictures yet. I tried all the ones on the wiki but they don't change the EV.

Anyway, thank you so much for continuing on working on a CHDK for the Ixus 85, very appreciated.

Great work, many thanks. Joined to thank and report a couple bugs I've come across playing with it. I don't know if these are specific to the SD770 or the CHDK version, I don't have another Canon on hand to test against, or time to get into another codebase right now, but figured it would be good to note them. All of these were with the latest CHDK image in the thread loaded on an otherwise clean SD card formatted for the occasion.
1. (meaningful bug) Using the "Evaluate White Balance" feature crashes the camera.
2. (minor bug) In display mode, when the tilt sensor flips an image, any CHDK stuff on-screen is not always redrawn after the flip, but remains active, and often redraws incorrectly at the next interaction.
3. (totally irrelevant bug) The Sokoban game doesn't seem to work

Hi, pedropaislopes!
I report on results of test corrected CHDK:
- serial shooting still does not work;
- in a mode of extra long exposure the device is switched off (on version 0.9.9 - OK).

PAPPP
1. (meaningful bug) Using the "Evaluate White Balance" feature crashes the camera.

I confirm. The device is switched off at attempt to make shooting after an estimation of balance white (on version 0.9.9 - hangs up at attempt to evaluate white balance and then crashes).

PAPPP
2. (minor bug) In display mode, when the tilt sensor flips an image, any CHDK stuff on-screen is not always redrawn after the flip, but remains active, and often redraws incorrectly at the next interaction.

Observed only once.
P.S.: on you, dear pedropaislopes, all hopes because I can't correct anything: "I the reader, I not the writer". 😁
Thanks!

Hey Pedro!
Thanks for your efforts! It's much appreciated!!!

Hej,
thanks for your work.
i tested the new versions, but my camera crashes when i want to take a picture. Maybe i have a different firmware, i will check that soon.

First of all, thanks to pedropaislopes for the work on the code!

I had this problem too. The problem for me was that I used the diskboot.bin from post msg44770. This one does not work correct. Use the version from post msg44399. For the other files i have used the bins for Ixus 80 (1.01B).

I am really looking forward to play around with the HDR capabilities of the CHDK tools. Can anyone explain (or give links to) how this works for this camera? Or isn't this possible since continuous shooting isn't supported (yet?).

ViSt

Aha, there's such situation: on firmware of version 0.9.9 "from post msg44770" the device for some reason began to be cut off by pressing the Shutter button. Before the such it wasn't observed. Probably the problem is connected with reduction of a charge of the battery. To understand further did not become, has returned the first version CHDK 0.9.9.

Yes, without possibilities of serial shooting not to manage.

Just found another problem with the diskboot.bin from msg44399: when the flash is used when shooting a picture, the camera crashes ???.

Hello, very new to CHDK but not to Canon cameras (I have two) and just want to say, awesome work! I'm extremely amazed already at the advanced functionality I have now over stock... But I wonder, is anyone still developing for the SD770? I'm able to help out with testing and would love to see a final release!

machadojon

Hi I just find out about CHDK! I'm looking forward to a full version to the SD 770!!!

I would like to know if any one is working on the development! looks like that stop on January!

regards,

Good luck! if need any help pls let me know!

Jon

machadojon

Any one is working to finish this Chdk??? money is needed? Can I help?

I just had the camera and would like to have the advance options.

regards,

Jon

I spent hours looking through and tweaking the code and disassembly trying to fix the bug with continuous shooting with no luck. I have some experience programming but not with assembly or CHDK, so I have no idea what I should be looking for. Does anyone have some pointers for fixing this bug and finishing the port?
