Starting CHDK in shooting mode?

Hi guys,

I've been playing around with CHDK for a while, and have been looking around to see if it was possible to start CHDK in shooting mode. (i.e so you can take pictures straight after you've pressed the power button)

At the moment I'm using Canon SD870IS with firmware 1.00C (ixus860_sd870-100c-0.9.0-660-full.zip). The camera just starts in playback mode after powering on, and I have to press the shutter button to go into shooting mode.

Is there way to getting around this? any help will be appreciated

Thank you so much,

David

Hello & welcome, David !

there are 2 possibilities atm:

1) Manual method: (->wikia)

With 'Clock Display' set to '0 sec' in the Canon menu, the camera can be started direct in record mode by the following workaround: Hold FUNC while pressing POWER, release FUNC when the Canon clock display appears (~ 1 second)...

2) a script, used with the autostart mechanism: (->script)

Code: (sdlbasic) [Select]
@title SD870 Bootup
if autostarted = 0 then goto "Exit"
if get_drive_mode = 0 then
  click "shoot_half"
  sleep 1000
endif
:Exit
  cls
  exit_alt
end

Sorry I'm brand new and dont know where or how to ask this:
I have two sd870is 2G in each and use them for stereo pics and vids. I am currently running (ixus860_sd870-100c-0.9.8-735-full). I recently and for the first time messed with video parameters and jacked up the bitrate to 3X. The camera stopped recording on it's own after a short time. The video clearly had much higher detail. But then later after bringing the bitrate down, the next recording resulted in what I would guess is a full card. One cam stopped on it's own and I couldn't access the card "card error". I can not access the videos on that cam. The other cam did not do this and I was able to view those videos.

Did I just use up the memory on that cam's card. Is there a way to keep that from happening in the future? Thanks, Pantelis

Pantelis I'm relatively new too. But I was wondering if updating your chdk using a card reader might help for the affected one?

Fe50 sorry for the late reply. Thanks again for showing me the script to autostart in record mode. I've also tried this one with no luck. . . . would you know of another way around this? Im using ixus860_sd870-100c-0.9.8-758-full, and wasn't sure if that is the problem?

@Pantelis:

Use a lower bitrate, the video recording stops when the card can't handle the data fast enough...
To ensure that the file system of the card is ok you should check this, e.g. with fsck (Linux) / Scandisk (Windows) - or backup your images, videos & your chdk folder, then format the card, install CHDK again and copy the CHDK folder from your backup to the card...

Load the script, then set "Script Autostart" to [ON].

The script checks whether it is autostarted; when you manually start the script, it does nothing: if autostarted = 0 then goto "Exit"

fe50 Thanx again for your prompt reply.

I've tried it, following instructions correctly. with [script autostart] set to ON. Upon restart I cud see a flash of the ***Autostart*** message in the lower left corner when the CHDK logo comes. but the camera still launches into playback mode. :(
Could it be due to the version of chdk that i'm using? it the latest build i downloaded few days ago.

Any further help is appreciated.

Thanks heaps

Hmm - tested the script again on my SD870, works fine, also with the boot splash enabled, with power button and also with playback button...

Maybe the latency value for your camera/card is to low, try sleep 2000 in line 5 of the script;
i've attached the updated script to this post, download & try it...you can also use higher values (e.g. sleep 3000) and then decrease the value stepwise...

(The sleep 2000 command just waits for 2000ms = 2 seconds to give the camera some time to do internal bootup stuff...)

daviewoo - try this "new" one (also attached as file 'auto2.bas'):

Code: (sdlbasic) [Select]
@title SD870 Boot2
if autostarted = 0 then goto "Exit"
sleep 1000
click "shoot_half"
sleep 3000
cls
:Exit
  cls
  exit_alt
end
BTW - what card do you use ? - maybe a very slow one with a big bunch of images on it ? ;)

Heya fe50,

Thnx for keeping my hopes up :)
the SD card that I'm using is Transcend SDHC 16GB class 6. Shouldn't be too slow i think. there are still 12GB left on it.

Gonna give the new code a try.
Thanx again for your help.
