Hi!
I have tried CHDK (latest release for the A530) and enabled USB remote trigger, and synch trigger. But the camera still took a picture immideatly when it got voltage on the usb-trigger.. not on the falling voltage.
So I got the tips to try SDM-release, I downloaded and installed on camera, enabled remote trigger, voila, it worked with falling edge at once.
Do I need any extra-script or something to get regular CHDK to work with falling edge trigger?
It works in SDM like I want but i cant seem to adjust the ISO settings / other stuff I want to fiddle with..
