SD990

[Darrelj]

Ok, I did exactly that, and it did work.  I set it to 1/3 EV, and it took three pictures, one at 1/60, 1/40 and 1/80 shutter speed.  I expected the exposures to show on the +/- readout, rather than the shutter speed.

SX10 CHDK has enable ISO overide in ISO3200 mode.
Will this function work on current version 980IS CHDK?

Hi everyone,

I also have a recently purchased sd990 with firmware 1.01b, and use CHDK in several other cameras.

I would like to help with the porting for this version. I'm not a programmer, just an enthusiast.

I was reading here;


http://chdk.wikia.com/wiki/Adding_support_of_a_new_camera#Requirements


that it may be possible to modify an existing port for a camera; I'm thinking the sd990 with the 1.00e firmware, compare

the files and make necessary changes. Like I said, I'm no programmer but am willing to try this. What/how do I need to

compare and modify?

This is probably beyond the scope of these postings, but you never know unless you ask!


thanks for all the good work and the time contributed,

Curt

You have misunderstood. You will not be able to do this if you are not a programmer with a reasonable grasp of C and assembler.

Test build for SD990 101b. Please note, I do not have an SD990 of any kind, so this is totally untested. It probably won't melt your camera, but it could easily crash. If you choose to try it, it's at your own risk.

Both a diskboot.bin and ps.fi2 are included. To test, I suggest installing the full SD990 100e build, and then copying the enclosed PS.FI2 and DISKBOOT.BIN to the root of the SD card.

Attached patch is for developers who may be interested in debugging, it is not required to run.

patch will be attached to next post due to attachment limits.

Thanks for working on this!

Spent a little time on the 1.01b version.

No crashes at all.

The biggest problem I have is the font size. I had to enlarge the menu fonts to the largest arial font in order to comfortably read the menu. I am unable to find a way to increase the size of the OSD font as of yet. They are pretty small, but still legible.

The menu is off to the left, not centered like the other CHDK's I have used.

All of the Shutter/ISO/Custom ISO functions worked well for me. I did not try any bracketing or scripting yet.

All the video functions that I tried worked fine.

The clock and battery work fine.

Writing RAW files works ok. I did not do any DNG conversions.

The control wheel does not work while navigating the CHDK menus, not sure if it is supposed to or not, although I think it does work in my SX110.

Not sure about being able to auto boot in something larger that 2GB, but that seems to be about the max size for auto boot. 4GB will not, although I did not try with Card Tricks, I just copied the files over.

I was mostly interested in a way to control the shutter speed better and this does seem to work well.

I hope this helps to keep the ball rolling.

Hi reyalp

Thanks for making a port that work with the 1.01b firmware. This is what my preliminary testing has revealed.

Testes/working features:

• RAW works
• DNG raw files also work, at least Photoshop and Picasa knew how to read the files.
• Override shutter speed
• Override ISO value
• Histogram
• Changing color of the menu and OSD elements
• Scripting, attached output of libtst.lua
• The menus are centered, unlike what Digiman1946 reported

broken features:

• Grid lines - are only shown on the left half of the screen.
• Games - are also only shown on the left half of the screen.

Thanks for testing and detailed reports, sounds like it's up to where the 100e version is. I'll check it in and add it to the autobuild.

Most of the screen weirdness (grid lines, games etc) is due to the 720 pixel bitmap width which is unique to this camera. Same for the apparent small font size. Menu centering should be an option. You should be able to create custom grids that work on the SD990, the grid format is described on the wiki. The standard grids are just made for a 320 pixel display.

Note that if you already had CHDK for a different camera on the card, you might end up using the cchdk.cfg from that, which would affect the positions of things etc.

Some existing, known bugs that don't need to be reported (for both 100e and 101b)
- zebra, edge overlay and curves don't work
- Intermittent raw. If you press the shutter quickly (or maybe some other factor), RAW/DNG may not be saved.

Since I don't have this camera any more, I probably won't work on the display related stuff. It's just too fiddly to do without being able to test it. I'll probably try to get to the intermittent raw one eventually.

edit:
Committed, will be in autobuild 792 and later

Thanks reyalp, being able to shoot in raw with the IXUS 980 firmware 101b is brilliant.

[reyalp]

I think I've fixed "Intermittent RAW: if you press the shutter quickly, RAW/DNG files may not be saved"

Test builds at http://drop.io/reyalp_chdk

If an SD990 user can verify that this works, I'll commit it.

The display setup is very similar to D10, so I may be able to finally fix some of those longstanding issues as well.

Sorry just noticed your post,  uploaded your port and tried several shots (20) using the autobuild and your new build.  both operate the same,  if you quickly press shutter only jpeg is saved, if you hold shutter 1/2 pressed until focus lock both DNG and jpeg are saved

Hi reyalp

Just saw your message.

I have tested your build from drop.io and it works on my camera (firmware 101b). I tried a number of different settings: auto, P/M (auto, macro and manual focus) and QuickShot (all of them both with and without flash) So I think that you safely can commit your changes.


Yours

DryDuck!

@DryDuck:
Does raw/DNG save correctly if you pressed the shutter quickly ? If not, then this is no point committing it.

@hnikesch
Which firmware version of SD990 do you have ?

[hnikesch]

I have firmware 1.00e  

DNG + jpeg save is very consistent, push shutter quickly and only jpeg is saved,  hold shutter 1/2 pressed until focus lock and both DNG and jpeg are saved in P, M, SCN, and quick shot modes
