IXUS750(SD550) - metering modes query

IXUS750 / SD550
1.1.0-2004 rev 0
fw 100f

Have been using CHDK for a few months now, really only to gain raw support

One irritating thing about the 750 is that it will not default to spot metering mode, which I use all the time.

Is there a workaround for this by scripting ? It would be good for the camera to run a script on startup which set it to spot mode.
Or is this beyond what CHDK can do or is designed to do?

thanks in advance for any help or suggestions

Yes - write a simple script which emulates the needed key presses & exits <Alt> mode...

OK thanks.
I know it's been said before, but navigating the wiki to find the basic information needed is horrible, and understanding what's written there must be a nightmare for anyone who's never been involved with code of any sort.

this however seems to work, ugly as it is:

Code: [Select]

@title set-spot-meter
click "set" 
sleep 500
click "up"
sleep 500
click "up"
sleep 500
click "up"
sleep 500
click "right"
sleep 500
click "right"
sleep 500
click "set"
sleep 500
exit_alt 0

I have marked this as "solved" but have a further query on the functionality of the script and so have opened a further thread here ...
