I have a very specific issue: I use CHDK for KAP, Canon SD300 and Gentle-CHDK USB. CHDK works fine. I enable USB remote and the servo that came with my Brooxes KAP kit triggers the camera every 10 seconds-no script needed. I also have been able to use many of the intervalometer scripts available, with the benefit of taking shots every 5 seconds. The problem is this: if I use the USB trigger, the first shot focus locks (pre-focus) the camera and the second shot takes the picture. This is actually good, b/c I'm getting better shots, but I end up with one shot every 20 seconds-much too few for my taste.
If I use a script, the camera does not pre-focus, and though I get more shots, more are out of focus.
Is it possible to increase the rate of the Gentle-Chdk-USB (the servo also rotates the camera after each shot)? or...
Is it possible for a simple intervalometer script to give a command to pre-focus and then a second command to take the picture? I haven't found one (the one I tried, lapse.lua did not run)
