Thanks, the modemap valued that you posted are the same for A3300, the user manual for both cameras is the same too. So, I updated the A3200 modemap table using A3300 values.
I would not take the a3300 as a reliable source. The question is, *does it work* ? Are all the values actual settable modes, and do the names match what they do? I know you don't have the camera, but perhaps someone else can verify.

It looks like the sigfinder ignores mod values from 8k-9k, which explains the warning
Code: [Select]
Current modemap entry not found in firmware - MODE_SCN_POSTER_EFFECT    8743
etc.
This was probably done because on older cameras, the 8nnn modes are C modes which aren't really modes at all. Assuming these values work, the sigfinder should probably be modified.
Don't forget what the H stands for.

Fixed finsig_dryos for R47 cameras in revision 2019 (trunk) and 2020 (release-1.1).

Sorry for leaving you alone.
Excellent work.

Over the weekend I made some tests with my A3200 Stereo rig.
If you do it right you get nicely synced  3D Photos.

But you do not get the reliability of SDM for shooting.

Where do we continue with the A3200?
Just compared the 2010 and 2022 builds.
Someone changed the menus.
I like that.
Makes it difficult to continue.

Could not find for example the color palette in 2022.
In 2010 there is a limited palette compared to a Ixus860.

Mostly it shows an "ugly orange" instead of a nice green in the menus.

That reminds me of my early testing with the A3200.
Had to change a number in one of the scripts to get a readable display.

Regards
Paul

Thanks. I started with this port because LED addresses were available, that was your work.

Tables in shooting.c need to be checked and improved.

Modemap entries were taken from other port, so they need to be tested. Please test its values with the version in attachment. 
Please test if adjustable ALT mode is working too.

After that, we could continue checking ApertureSize and ShutterSpeed tables, I need to learn how to do that correctly.

EDIT: Obsolete attachment deleted

So the SDM version for the A3200 works better ?

There is no SDM version for A3200 available.
I compared the SDM version with the CHDK version for other cameras.

Today I had only little time to play with the CHDK menus:
Setting the ND Filter is working (Darker Display in Record Mode).

I have an A3200 model with 1.00A firmware version. Please post the link for the complete guide to port my firmware...
Thanx

First thing is to thank all the people behing chdk
I have just started testing it in my A3200IS camera, and it's working!
So far I have discovered one thing when capturing in raw mode.
I have selected to save the photo in jpg as well (at the same time)

Here you can see a screenshot of the two pics compared.

http://img854.imageshack.us/img854/2576/clipboard01dl.jpg

The DNG file is on the left
The same photo, but in jpg format is on the right

The dng presents some problems:

It has some kind of spheric problem
As you can see, the grid in the jpg is correct

It has some black borders in the photo itself
See the borders to the right and the bottom of the dng file
The jpg hasn't got these borders.

As you can see, the portion of the image captured is not the same in the photos
For example, you can see the word "on" to the bottom of the dng file, but it isn't there in the jpg photo.

Also, the tungsten mode only seems to make effect in the jpg file.
The dng file seems warmer, pinkish to me.
Maybe this is always the case in raw mode (I am sorry, I am a beginner in photography)

Can somebody explain me what I am doing wrong please?
Thanks.

You are not doing anything wrong other than not understanding what CHDK RAW is.

CHDK RAW is a dump of the actual data coming from the camera's sensor.  What you are seeing is exactly what the sensor produces.   The JPG files are heavily modified versions of that same information where the Canon firmware has made changes to clean-up the image and compress the file size.

Here's more information if you want to learn about CHDK RAW :

Thanks for pointing me into the right direction
I have been reading some of the posts and by the looks of it, maybe I would have to stick with jpg for the moment
I just don't feel capable of creating that profile, maybe if I have more time in the next weeks...
