Hi,
I'm trying to get motion detection to work on my SX30 and and trigger continuous shooting for 7 shots.
I'm using the latest CHDK firmware.
I have the camera set to continuous shooting - I'm running on custom settings C1.
I'm running CHDK auto Iso as well.
I'm trying to adapt the following md universal.bas script for my SX30 (SEE BELOW).
I had to make some changes to the script using:
http://chdk.wikia.com/wiki/PropertyCaseWhen I run get_prop 102 y => it returns a state of 1, which indicates continuous shooting with no autofocus.
I had to change the prop id from 6 to 102 to get the proper drive mode read (if it is actually necessary).
My script runs as follows:
I turn on the camera - press CHDK button to get alt appearing.
I start the script after the prop id change - I get 24 green squares and everything seems to work.
If I wave something in front of the camera the motion is detected but... nothing...
No photo(s) are taken by the camera, green grid disappears and the camera goes to single green focus square.
It appears to go to the focus state and stops.
I have to restart the script to get the grid back again.
I want to be able to leave the camera and let it take 7 shots whenever motion is detected.
Any suggestions?
