missing DISP button on newer cameras

Newer cameras do not have a separate display button. But the DISP button is an important CHDK button. I think we need an uniform replacement. My suggestion - the video button. The video button is not used in any CHDK alt mode function.

For some cameras is the DOWN button also defined as DISP button. With such cameras you have to try to use the layout editor (Pixel stepwidth & move down are the same, that's funny!).

The use of the video button has been successfully tested with the s100. See also http://chdk.setepontos.com/index.php?topic=650.msg102697#msg102697

???

They all have a separate DISP button. I talk about (newer) cameras without a native DISP button!

Why has nothing happened to this? The solution with the record button seems to be fine. Is there already a ticket for this issue?

Probably because nobody has found the time or interest to work on it.  That happens some times - there are not many people actively working on CHDK who have the skills and knowledge to do this and they get busy with other things.

CHDK does not have a ticket system,  or a schedule, or even much of a plan going forward.  It's just a small group of volunteers who work on things that seem important or interesting to themselves.

The solution used with the S100 looks fairly easy to implement.  If you'd like to test it,  I'll need your camera model & firmware version.

If you have time to look at a solution for the D20 while you're at it, will you post a patch for me? Thanks.

I've been using this statement in my scripts:

if  (is_key("display") or is_key("video")) then

A general solution might be to look for all the CHDK functions that use the display key and add a test for the video key too? Thanks.

Please report if this works and I'll submit a patch to the autobuild for everyone to use.

You don't really need a patch file - just add

Code: [Select]
#define CAM_DISP_BUTTON_NAME  "Video"to your platform_camera.h file.  Let me know if it works and I'll include the D20 with the A810 when I submit the patch.

Never heard back from der-graf-von-foto so no patch was made.  I now expect it would not have worked anyway (see below).

Really ?  That now seems strange.  When I looked at it closer, I think that you also need to change the keymap[] in kbd.c so that the bit map for the "Video" button is assigned to the "Display" button.  The #define only changes the text field used in the annoying pop-up help box.
