I'm new to CHDK and fairly new to my Canon G9. I am using an Arduino to pulse the USB remote to take a picture. I have this working but when it gets triggered it takes the camera about 1.5 sec. to take the picture. I am in manual mode and it appears that it is doing some other stuff before it takes the picture. Is it possible to get the camera to take the shot as soon as the USB line goes high? If so how would I accomplish that?
