one push triggering

Post by jancoj » 08 Feb 2012, 04:44

Can anybody help me how to use CHDK one push remote triggering on Camera A490. I have managed CHDK running on camera but in remote settings there is no choice for one push. I have to to push the trigger twice. Do I need to write a script? Any help much appreciated. Thanx.

writing a scripts is the answer, also for mutch more possibles,

but for the beginning
wirte a file in the
CHDK\SCRIPT\ folder
like oneclick.lua

and place in it

Code: Select all

click("shoot_full")
then in the chdk menu actvate remote funtion and load this script, this should work

Hi Gerard,
I have tried to write that, but the script doesn´t do anything. I am not sure If I wrote it properly. Is it only - click("shoot_full") - in file? But I found the another way seems to be working. I enabled synchable remote in CHDK settings and now it works when I push the trigger once. Hopefully it will do good job. Thanks for help.

oh i was using chdk de, in chdk you can run a script with usb remote

but the sync remote is the better solution

We used the remote triggering via USB port for our 2 Canon A2200 cameras on our book scanner. I hooked both usb cables up to regular USB Port charges like you use for MP3 players, cell phones, etc. Then plugged those into an extension cord that runs to a foot switch. When pressed the foot switch focuses the cameras and when released it triggers the photos. It works great for us. The entire setup is posted with photos in the oversize scanner topic. The foot switch you can now buy at Harbor Freight for under $15.00 US. I paid 33.00 or so on Ebay 2 years ago.

Hope this helps.

Mike
