@Caefix

Replace the core \ gui_osd.c file with the file attached in this post and recompile. You will see something similar to this picture.
Just count which digit changes when you press one of the zoom keys, the value doesn't matter. You need to count from right to left.
The changes will likely be in the PS1 or PS2 line.
Each zoom speed should be seen on different digits.

Code: [Select]
       [ 2]
PS1:   0420 no zoom
       0020 <|<<
       0400 >|>>
PS2:   [  6] is changing during optical zooming <> or <<>>, stops at the edge or digital zoom.
vals=  0420,0400,0020 or 0000.
  :haha   :blink:
The only IXus I saw so far with double defined zoomkeys is ixus1000_sd4500.
There the zoomlever is quite massive and the two speeds are visible...

This is a never-ending story :)
What does that mean?
Is it a slow or fast zoom speed or is the same bit changed for both speeds? For one change you used the same characters, which you used before for different speeds.
These changes show already known values:
Ove promjene pokazuju već poznate vrijednosti:
 { 0, KEY_ZOOM_IN         ,0x00000200 },
 { 0, KEY_ZOOM_OUT      ,0x00000400 },
We still don't know the values for other zoom speed.
Each digit in the line represents one bit. In theory, when you press a key one bit changes its state. It can be that some of the speeds change more than one bit. This means that while holding down the key, multiple digits can be changed at the same time. When you release the key, the changed digits should be return to the initial value.

Code: [Select]
PS2:   [  6] is changing during optical zooming <> or <<>>, stops at the edge or digital zoom.
vals=  0420,0400,0020 or 0000.
As I wrote before, the changed bit must keep the same state all the time while the key is pressed. If this is not the case, then probably these changes represent something else.

Maybe the camera only has one zoom speed. 8)
Can you zoom at different speeds, regardless of chdk?

No matter, sometimes it’s good to spend time on nonsense.  :D

I have "something" for that camera but only for the firmware version 100d.
The port is completely untested, I don't know if it works or not, I didn't really waste too much time on it.
:xmas "Something" works...
