Hi, this week i´ve been doing some aerial photography, with my skywalker, canon camera and CHDK script.
More specifically, im using the Canon SX260 HS powershoot hacked with the intervalometer from dronemapper guys. I detect that this script wont work totally well if you speceify a photo interval of under 3 seconds. This is because the camera just cant shoot in continous mode under 3 seconds at a time.
So i posting this as a head up.
PS: If you specify, in the parameters, a interval of, let say, 2 second. The camera will take shoots continously, yes, but the script will never end and the lens wont colapse. wich is a bad thing because it can be hit or something can occur to the lens mechanics.

Andy, this is not entirely truth, because if you set the focus on manual, you can get flat 2 seconds per frame. I´ve done some testing on this with a stopwatch
@Andreas, Thanks for updating me, looks like some more tweaking is needed. Cheers, Andy
This is for Dennis Megarry. I'm up here near Cleveland. I saw your 13 Aug 2013 post: "buy a GenWIRE-USB2 cable and then message me, I'll give you a link for a customized version of Mission Planner for crop mapping. Let the autopilot control the shutter rather than tick off timed pic's ". I have a quad with APM 2.5, a Canon SX260, and a GenWire-USB2 cable. Can you send me the link you mentioned? Thanks!
You don't need that version any more.. the latest MP 1.3.5 has Survey Grid built in..
I am working on a LUA script for the APM which will extend, trigger and retract the camera lens.. You will have to put in some DO_SET_SERVO's to send the proper PWM values though.. I will be testing this weekend..
I had to make my own cable with a transistor in there to amp the servo signal enough for CHDK to register it on the USB port.
I recently upgraded to firmware 2.74b and my plane stopped logging CAM events. anyone know what log bitmask i need to start logging them again ?
Hi Ben, did you find out what bit mask is required to log CAM messages?
Andreas,
It may be the speed of your memory card that is slowing down your rate of image capture. Make sure that you have a Class10 SD card in it. With one of these in an SX260 I get 2-3 seconds fine.
Good luck!
Jimmy

Have you turned off the image review option? By default is set in 2 seconds.
