SX110IS - howto start porting

nycjv321

ok I used Yarvieh's binary and it works here 😁 omg this is soooo cool
but I am confused
I didn't know what the "shortcut" button was to activate <alt> mode was...
so I figured out it was "face focus" button to show the current feature and "Disp" shows the main menu... (up goes down and down goes up in the menu which is weird for me... but doesn't matter) so I am in amazement!!! All you develops are awesome OMG!!!
It makes a raw files that are 14.7 MB (15,467,760 bytes) in size but I dont know any application that opens raw files created by sx110 is but that isn't important right now..... it is just so cool that it boots!!!

Yarvieh

Been playing with the RAW feature all evening since i never used raw before so its kinda of a steep learning curve, since the math by chdkj and ewavr didn't come to a satisfying conclusion I wrote a quick app that just reads the file and displays the bayer matrix and have my eyes decide what looks ok 😀

Its 3720 x 2772 12 bit data.

Updated camera.h with this information and enabled DNG support, (see here on how to use) however when i process the file its overly blue so I think there's still something wrong yet no clue what (I suspect the color matrix but not sure), ewavr any hints and tips on this?

Have attached updated binaries to this post.

Code-related issues:
--------------------
- include/camera.h: cam_CFAPattern, CAM_COLORMATRIX1, cam_CalibrationIlluminant1, CAM_ACTIVE_AREA_* and a few other things

#define cam_CFAPattern 0x02010100 // Red Green Green Blue

haven't touched with the others.

- platform/<camera>/main.c: modemap --> as ewavr said: Using propertycase browser in debug menu (propcase #49).

static struct {
	int hackmode;
	int canonmode;
} modemap[] = {

- include/camera.h: properties need to be adjusted/corrected

I added these to make raw support semi usefull

    #undef CAM_SENSOR_BITS_PER_PIXEL
    #define CAM_SENSOR_BITS_PER_PIXEL   12
    #undef CAM_WHITE_LEVEL
    #define CAM_WHITE_LEVEL             ((1<<CAM_SENSOR_BITS_PER_PIXEL)-1)
    #define DNG_SUPPORT                 1

CAM_RAW_ROWPIX and CAM_RAW_ROWS where oddly enough already set to the proper values.

Well uhh it tells you whats wrong and what to do to fix it (as does the post I linked), not quite sure how to help you with that 😀

If you don't have a copy of the script it mentions it grab a copy of a daily build for another camera and copy over the CHDK folder that contains all fonts and scripts and icons etc etc.

Yarvieh

Since chdkj had a reasonable status report I'll just update it with what i did today.
I attached a patch against svn revision 729 and the latest binaries.

Current status:

Code-related issues:
--------------------
- core/kbd.c: ZSTEP_TABLE_SIZE, nTxtbl
- platform/<camera>/shooting.c: dof_tbl
- include/camera.h: CAM_COLORMATRIX1, cam_CalibrationIlluminant1, CAM_ACTIVE_AREA_* and a few other things
COLORMATRIX --> I've read in forum that DGN4PS2 should be used for
- include/camera.h: properties need to be adjusted/corrected

Problems:
---------
- LCD screen sometimes flickering (red snow)
- zoom wheel doesn't work from time to time (haven't noticed this)
- shutter button doesn't work from time to time (haven't noticed this)

Solved:
-------
- keyboard: mixed keys, wrong assignment, JogDial up/down is swapped
- modemap
- scripts: badpixel.lua success (or atleast on my cam)
- switch to new code base (trunk) (synced up to 729)
- implementation of firmware update method (see earlier post on where to obtain keys)

Kinda Solved:
-------------
- Raw all code is ok, the file generated is ok just nothing seems to be able to process it, if you use DNG it gets a blue haze other then that looks good maybe CAM_COLORMATRIX1 related? Wrote a quick app to verify the CRW files and they look OK as well. Its just up to 3rd party apps to support this format. If i have time tomorrow i'll email a patch to the dcraw guy.

Others:
-------
- battery indicator relies upon estimated values and might be wrong

Nice work everyone! Looks like after chdkj got the camera to boot up a lot of other people got interested 😀
Mostly I need CHDK for bracketing and it seems to work with no problem, at least in the latest version by Yarvieh 😁
My programming skills are pretty limited but I'll do some beta-testing ..

Keep up the good work guys! (oh, and yeah, six pack for every developer out there from me too)

Corrupted zebra?

Corrupted zebra?

I have just little experience with this, but yes, I would say corrupted zebra..
When Zebra is disabled theres no traces of snow anywhere.
When Zebra is enabled and shutter button is half pressed theres red snow everywhere (Blink mode), the pattern changes little bit so it really looks like snow. If Blink is changed to Zebra, the snow transforms into "red zebra-snow".

No matter what threshold settings I use, Zebra mode wont work like it should. Thou.. If I keep shutter button half pressed long time, theres some rare short flashes of the real zebra pattern on the over-exposed parts (like it should).

Yarvieh

I left that item on the list cause it was on chdkj's original list I haven't seen any of the red noise he mentions though (but have to admit haven't been looking for it either) The zebra however is definitly corrupt I'm getting none of the 'it kinda works' like axu89 has. It looks more like pure random data overlayed on the image, probably getting data from a wrong memory location somewhere. Its not too high on my prio list but if anyone wants to have a go at it, go nuts 😀

My Current (and probably only) objective is to have raw(almost)+bracketing(working great) working so I can use this cam on my gigapan unit anything else that gets fixed on the way is just a nice bonus. 😀

magicmanevan

The zip files that Yarvieh and chdkj posted, are those files able to be put onto the SD card from CardTricks?

Or are those files to other people to work on?

If they are files to be put onto the SD card, can someone tell me how to do so? I have tried using Card Tricks but when I turn on the camera, I cannot find the CHDK no matter how many diff. options I try.

nycjv321

no point in using this firmware if you can't even manage to load it....
you should check this out http://chdk.wikia.com/wiki/CHDK_for_Dummies

magicmanevan

I got it working, this is great! Thanks to all who helped to develop this!

xterm

Great guys i was waiting for the porting. I want to use it with my gigapan unit for bracketing. Thanks

axu89

Someone with better knowledge could update the wiki-page? http://chdk.wikia.com/wiki/SX110IS

mikado

how install this chdk please? thanks

popo_caris

Yes, How Install??? Pleaseeee!!!!

Thanks

3. follow these instructions: http://chdk.wikia.com/wiki/CHDK_for_Dummies

zodiac757

hi guys!
is this chdk the final version or an alpha (or beta)?
is it possible to play divx videos with the camera or it needs a really hard firmware hack?
