IXUS 100 IS (Europe) / PowerShot SD780 IS - Porting Thread

HarpoMa

Thx. I will head in that direction for debugging it.

I wanted to thank you for the suggestion of irfanview. I can now actually see the raw file and amazing but it has the image I took. LOL

Hi.

I have tried the V3 firmware and want to report my experience:
Storing of RAW works but as already said.. no program recognizes the file.

Saving to DNG also works once "badpixel.bin" is present.

For badpixel.bin creation I used badpixel.lua which worked after some retries, but I don't know if the content contains correct badpixel data or not.

Additionally I have tried a simple lua script which did not work.
Lua script:

--[[
@title Test Lua Script
]]

function forceRecordMode()
	repeat
	  if get_mode() == false then
		 cls()
		 print("Run in Record mode!")
		 sleep(3000)
		 cls()
		 exit_alt()
		 sleep(1000)
	  end
	until get_mode() == true
end

function fastShoot()
	press("shoot_half")
	print("shooting...")
	press("shoot_full")
	release("shoot_full")
	release("shoot_half")
	repeat
	sleep(1)
	until get_shooting() ~= true
end

forceRecordMode()
fastShoot()

Function forceRecordMode() works but function fastShoot() doesn't work (no picture is taken) however completes without an error.

Anyway.. keep up the good work.

@Quikee,

Thx for trying it out. Your observations are 100%. I only started looking at the scripts last night. Turns out my kbd.c was missing the code (i wondered what it was for) that would implement scripted actions. LOL

The badpixel.lua will work as you said until I release v4. As you thought it is not valid data but is required for DNG output to work. You can try irfanview if you want to see the raw file but DNG is easier.

I'll get forceRecordMode lua working tonight and release v4. Then you can try it again.

Again thx and things should be better soon. It's still pre-alpha so most things don't work at all. It's really just a pretty gui atm.

It's been a bit but I'm looking for SD780 testers now. If you want to test please create a post and submit your bugs. There are tons of stuff thats wrong i'm sure but I'll just work out each bug and hopefully it covers more then just that bug.

I prefer to have people create a single post and update it as bugs are fixed and retested. So if you could follow that style it will help me greatly. As bugs are fixed just use the ~~strikeout~~ style.

As always the first post has the latest info on status on build info. For your convienence i will place it here too...

Pre-Alpha Firmware (v5 updated Sept 19, 2009) (must rename ps.fi2) - PS.FI2 (Note: ALT is DISP key & DISP key is long held DISP)

Thx.

I will start testing on thursday, as soon as my camera gets back to me. If I manage to build this ;/

Right now I'm getting:
-> main.elf
../platform/ixus100_sd780/libplatform.a: could not read symbols: File format not recognized
collect2: ld returned 1 exit status
make[1]: *** [main.elf] Error 1
make: *** [all-recursive] Error 1

I'm building with:
gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3

Any help appreciated. Also, if someone could send me pre-built package, this would be cool. Thanks!

I will test as much things as I can as soon as I get my Ixus back - which is unfortunately not before Monday.

I am glad you got movie overrides to work because the default bitrate of around 20kbit/s is just overkill. I have reencoded the videos and got an acceptable quality at almost 1/10 of the size of the original.

Looks like you are ending up with a mix of arm and non-arm tools. Note that CHDK is picky about the toolchain, you can't just use someone generic ARM cross compiler, you need to either build it yourself or use one of the pre-built ones specifically configured for CHDK. Then you need to set your path and other environment variables so that is used for the entire build process.

@mstawick

also make sure you're not using binutils 2.19 or greater

I just started testing

* On video the the optical zoom will zoom in then the digital zoom will take over
But when you zoom out only the digital works. When it gets to optical zoom i get a "!"

HarpoMa

The current source is not upto date. Just use the PS.FI2 for now...

OK, thanks for support. BTW, I finally managed to build it under Windows using chdk-shell.

Hi, I've been following this thread since the first post, and registered just now to help testing, although i'm new to CHDK and have never used it before. But i bought the Ixus 100 having in mind that someone would hopefully make a port.
And HarpoMa, you did a great job so far. Thx for that! 😁

Since i'm new to CHDK i'm just getting started, but there are 2 issues i noticed so far:

Not possible to switch between original canon modes auto and program while CHDK is loaded
Exif data is not correct when using overrides

But i'm sure you are aware of that. 😉

Looking forward get myself into scripting, but i have not tested that yet, cause you haven't touched that by now, as stated in your first post.

Great work so far, keep going. 😀

HarpoMa

@Duke,

Feel free to try anything. I haven't specifically touched scripting but that doesn't mean it doesn't work. Lots of area is generic and works once the base port is working. If you do end up testing it just edit your original post and I'll watch for any changes.

Issues I found:

If "fast Ev switch" is enabled the Ev switching is bound to the same values as self timer (down).
Self timer is not recognized as continuous mode which makes it unusable for bracketing.
Could not get badpixel removal to work. I have a bad pixel and used badpixel file to set the coordinates of the pixel using DNG to determine the coordinate in an (raw) image editor.
Remaining video time in video mode is not shown if enabled.

This is for now...

Jensemann

Two more (small?) issues:
- in video mode the AF Key doesn't work (I thought it did on my first test...)
- CHDK menu exits if cam autofocus detects something

But still I'm absolutely impressed by your great work Harpo! 😀 *bow down*

I was able to successfully load alpha V5, I'll put bugs here.

Bug list:
=====
No new ones.

These were copied by HarpoMa to the summary, so I 'removed' them:
* Cannot open RAW (even in IrfanView),
* Cannot open DNG in LightRoom, Photoshop; IrfanView opens,
* Menu sometimes dissappears (even in 'P' mode, when camera doesn't autofocus); i'm not sure exactly at what conditions this happens,
* The camera (canon-generic OSD while taking the shot) shows fastest time as 1/1500 (even if override is set higher) and the highest ISO as 8000 (same gets written in EXIF). I have compared shots taken with ISO8000 and ISO1600 - no difference. I don't know what to think about it. Either the real highest ISO is like 1600 or something doesn't quite work with override. Sorry if I have written something totally retarded,
* In "shutterspeed enum type" = "Factor" the longest time is 15". In "Ev step" is 64". Is this correct? I was hoping for longer,
* Bracketing doesn't work with custom timer. It does work with manual continuous shooting same as quikee (2),
* SUGGESTION perhaps Ev quick switching would be better with zoom-in / zoom-out controls with alt active; also navigation through menu would be easier with zoom-keys, or is it only me?

Jestik

i've never used canons and i'm very happy with chdk! Thanks you for your job.
I found a bug. When i make movie and use optical zoom, after 3.0x (when digital zoom comes) i can't bring it back to 1.0x -it just stops ant 3.0x

drakon

it's possible av overrides in ixus100 with chdk??
