Autostart and D750

Hi

I've just started working with CHDK and ran into one problem.  I have an SD1100 and an SD750.  I want to run the standard intervalometer on both.  On the SD1100 it works as I would expect and the camera begins taking pictures a few seconds after being turned on.  The SD750 powers up and display the CHDK splash screen as well as indicating intervalometer and autostart.  Despite this it never begins taking pictures.  If I press the shutter button, the display shows INTERRUPTED.  If I press the shutter button again, the display indicates Started and the camera begins taking pictures as I would expect.    Another odd thing is that it takes one picture every 15 seconds as expected but also another between 2 and 6 seconds after.

Am I overlooking something?

Thanks

Bruce

Is the SD750 starting in play mode ? This would normally be the case, since it has a play button rather than a multi-position switch like the sd1100.

In that case, you should make use the script to make it switch to record mode. You can do this by sending a click "shoot_full" or set_record 1. You will want to have a wait after that, to allow the camera time to switch to record mode. You can see setrec.bas and setrec.lua in the SCRIPTS/TEST directory for examples.

Not sure about the other issue.
Don't forget what the H stands for.

Does it do this same thing on both cameras ?

There are probably hundreds of intervalometer scripts on the wiki and forum but unfortunately, there is no "standard".  Are your referring to one of the two basic intervalometer scripts included with the CHDK installation files (INTERVAL.BAS or INTERVAL.LUA) ?  If not,  please post a link to where you found your script ?

Hi Reyalp

Right, it was starting in play mode.  I added the code to switch to record mode and it's working perfectly.  Thanks for pointing me in the right direction.

Waterwingsz:  Yes, it was just the basic example intervalometer script that ships with CHDK.

One of these two cameras is destined for a high altitude balloon.  Now I have to decide with one I want to part with should the worst happen and I don't get it back.  ;-)

Thanks

Bruce

If you search the forum, you should be able to find posts from several others people who have done successful high altitude flights.

Forum member fbonomi used an sd1100, some information here http://www.francescobonomi.it/photo-balloon
