Turn off shutter sounds? (A3400is)

Hi All,

I am brand new to CHDK and love what you guys have done here!  Anyways, i'm setting up my A3400is to run a intervalometer script that will be running for a LONG time.  The picture taking part of the script seems to be working great for me but i have a couple features I want to add and was hoping someone could  help me out.

I want to turn off the auto-focus sound that is made every time a picture is taken.  This will be very noticeable where i'm taking these pictures so that would be great.

I also want to have the script automatically turn off the LCD so the camera will last a lot longer. 

Are these possible?

Thank you!!

set_aflock(1) will just lock the autofocus for you.  To turn off sounds, you need to use the Canon menus.

You answered before I could edit my previous post.  Pretty good considering I got that done in under 30 seconds from the original post.

Thanks for your quick responses!

How do you actually put these in the script?  I added them to the script and nothing much happened.  I've attached the script i'm using here.

Try
  set_lcd_display 1
rather than
 set_lcd_display 0

Edit :  wrong - see below.

It looks like the screen turns off for a split second, but it comes right back on to display the picture and is on until the next picture is taken.  Is there anyway to set it to be permanent in the script, until i interrupt it?

That should have done it.  Do you have "Review" in the Canon shooting menu set to "Off"?

You could also try moving the set_lcd_display command to just after the shoot command but that really should not be necessary.

Tried both of those and they also didn't work. 

"BUSY" comes up when it's processing the photo and it looks like that might be turning the screen back on.  Your help is appreciated, hopefully we can figure this out!

I misled you earlier (would help if I actually read the web page I pointed you to or tested what I wrote - sorry).

Use :
Code: [Select]
set_lcd_display 0 to turn off the display.

I modified your script and tested it.  The display on my A1200 goes off and stays off (with Canon Review mode disabled).  I've attached the modified version.
