"Half shutter" key bindings in 1.1 on A810 (and others maybe too)

Hi.

This is my first report here so I might be messing up something. I apologise.

According to the manual (pp. 91 and 105) two (←, →) of the "Half shutter + cursor" bindings are used by the original firmware.

I've checked the source. I launched the following command to check what is the actual binding for SHORTCUT_DISABLE_OVERRIDES on A810 (I don't know the structure of the source tree very well yet but this seems the most logical).

Code: [Select]

(cat include/camera.h; sed -n 52,138p core/gui.c; echo SHORTCUT_DISABLE_OVERRIDES ) | cpp -I platform/a810/

I got KEY_LEFT. Which according to the manual is not appropriate for use with "Half shutter".

The effect on my A810 is that:

the fist time I press HS+LEFT: the overrides toggle;
the second time I do it: the AFL kicks in;
upon the third attempt the camera crashes.

Best regards,
ŁS

Conflicting shortcuts is an unfortunately common problem. However, it shouldn't cause a crash. The expected behavior is that both the CHDK function and the Canon function are triggered at the same time.

I've posted a link to this in the development thread http://chdk.setepontos.com/index.php?topic=8450.75

Don't forget what the H stands for.
