Hello,

I have a camera with a broken shutter button which I use with CHDK and scripts.
Until now I have used the Autostart feature for scripts to enable them to start.

Now I would like to try to modify the code and make my own build with the Set button as start/stop for scripts.
Could anyone tell me where in the code I should start to look?
I have not been looking into the CHDK code before but I have a lot of coding experience.

If someone have a better idea how to solve this problem, please let me know. ;-)

Thanks in advance!
/Erik

In \core\kbd.c, look at 'kbd_process()' lines 672 to 675.

http://tools.assembla.com/chdk/browser/trunk/core/kbd.c

That function is called from the camera's platform code kbd.c.

Thank you!

I found it this morning and have tested it succesfully.

There is a small issue with the script parameters meny showing for < 0,5 s when a script is stopped and then
all infomation is erased from the screen.
A easy work around is to press the menu button and the screen is restored.
There is also a problem when entering the menues and I try to select something with Set.
It seems to be some problem with the normal handling of the Set key.
I have not found where the Set key is handeled so if someone could give a hint I'd thankfull.
Or maybe I should use a different key for start/stop.

Btw, the CHDK-Shell rocks!!!

Hi again,

I used the Display key instead and know it works as I hoped.

Thanks again.

I don't think this will be my last modification of CHDK.
Hoppefully I can contribute in some way to the community as a thanks to all those heroes
which made CHDK possible.
