@ntstatic Are you ready for this?
This can only be done with the camera in hand, without this chdk cannot work properly.
The file that will be edited is attached.
Go to:
Miscellaneous Stuff -> Debug Parameters
set "Debug data display" to [Props] and "Propcase / Param data page" to [5]
Exit <ALT> mode and change the shooting modes.
The numbers on the left are propcases, on the right are possible settings.
Each time you change the shooting mode, you should see another number on the display (e.g. 32773 if your camera is in the P mode). It is necessary to find out which propcase is changing, I assume that this will be somewhere about 50.
For example, if is changed the propcase 58, you need to change #define PROPCASE_SHOOTING_MODE 55 to #define PROPCASE_SHOOTING_MODE 58
If none of these parameters change when you change the shooting modes, set the Propcase / Param data page to [4] or [6] and try again.
A similar procedure should be repeated for all items, but other parameters on the camera should be changed.
All the CUSTOM_XXX ones are things in the "my colors" menu
ISO_MODE is the ISO value you set in the func menu.
The USER_TV and USER_AV are the manual shutter speed and aperture values. They update immediately when you set them. The other TV and AV values update on half press.
SUBJECT_DIST2 / SUBJECT_DIST1
You should be able to check these in MF mode, they should have the same value, and it should change when you adjust the focus distance
DELTA_SV
Put the camera in AUTO ISO and half shoot. SV_MARKET will go to the base value (probably 576 = 200 ISO) and SV_MARKET + SV_DELTA converted to ISO should match the displayed auto ISO value.
DISPLAY_MODE
This should update when you press the disp button in shooting mode (maybe INFO on this cam)
FLASH_FIRE
Should be 1 after half press if the camera would use flash.
FLASH_EXP_COMP
Should show exp comp value in apex96 units
FOCUS_MODE
This should update when you change between Macro, standard AF and MF
OPTICAL_ZOOM_POSITION
should show the current zoom step, 0 at wide
EXPOSURE_LOCK
should go to one if you use the canon AE lock shortcut (half press, click +/- button)
IS_FLASH_READY
should go to one on half press when flash would be used, goes back to 0 on release.
ORIENTATION_SENSOR
Should be 0 in normal orientation, 90 or 270 in portrait orientation.
TIMER_DELAY
should update when you update the time in custom timer mode
WB_ADJ
should change when you change white balance mode
TIMER_SHOTS
should update when you adjust shot count in custom timer
