Change the shutter key on CANON S100

Hello, I'm a newbie (and french...  :blink:)

I've already read https://chdk.setepontos.com/index.php?topic=12825

But I've no file called kbd.c on my sdcard.

My issue :
The chdk is running out of the box.
But my S100 shutter is out of order...

I would want to exchange this key with, for instance, the video shutter one.

Is it possible ? How can I do ?

Thank you so much.

Sebatiduroc.

You need to modify the source code and compile the CHDK on your computer.

Note that you can't just swap the shutter with another key, because the shutter is actually two keys: shoot_half and shoot_full_only in CHDK code.

If you assigned video to shoot_full, then when you click it the camera wouldn't wait for autofocus etc, and most shots will be bad. If you just want to CHDK scripts, it might be OK.

If you post which Canon firmware version you have, I can post a build with this change.

But with slightly more code,  you could intercept the video key press,  do a "shoot half", wait for it to complete, and do a "shoot full".  A bit fidgety but more usable than just ramming through a full press without a pause in half press.

Thank you all for your help.

In fact, I just want to use a script (interval) in a particular way : KAP (kite aerial photo) with a infinite focus. So I think there is no problem.

LAST MINUTE INFO : I'M A STUPID GUY !!!

I've just to select "auto start"... And all is fine.
