Re: Camera dual triggering

Good news: I have reset CHDK on the camera and switched every device on the scanner off for some time before restarting. That has apparently solved both the disabling of the overrides and the original flash problem. I 'm preparing flashcards to install CHDK 1.3 with STICK. I'm sifting through the lo...

Re: Camera dual triggering

Hello Nafraf, I'm sorry to have kept you waiting. I've been ill and not able to work on the scanner. Thank you for your feedback. I'm recovering now and I'll check the Spreads' logs on the Pi and answer your question come Sunday. I've reset the chdk sd-card to default and that has taken care of the ...

Re: Camera dual triggering

Some more info the monochrome/flash issue: The flash activation first occured after I changed to monochrome setting. But it has continued after i had reset to colour mode, had restarted the cameras and Pi and had reloaded Spreadpi. So flash now also activates in colour mode. Setting Spreadpi to mono...

Re: Camera dual triggering

Thanks, jbaiter and nafraf. 1. I'm running CHDK 1.20 now. Will this work, or do I really need CHDK 1.30? If CHDK 1.20 will do, I'll try and reset the camera as specified. If that doesn't work I'll additionally reset CHDK to default setting. If that doesn't work I'll upgrade to CHDK 1.30 and reset th...

Re: Camera dual triggering

When the camera settings are in P, command to capture is given, the lenses zoom out, i can hear the bleep and the click, but no 'shutter' noise. the cameras do this once each with no flash, but instead of thumbnails and picture counts I get 'capture failure' messages. The cameras seem to take a pict...

Re: Camera dual triggering

Thank you! On the flash "turning itself on": I have manually changed the cameras' mode from 'auto', which seems to be the default setting, to 'P'. Then I have tried to trigger the cameras using the graphic interface via the webinterface of Spreadpi, by using the mousepad on the laptop to click on th...

Re: Camera dual triggering

Thank you for your swift and helpful reply. I'll try to answer some of the questions you raised. The Scythe pedal is the only input device directly connected to the Pi. The laptop is connected by wifi to the hub of my local network which is in turn connected to the Pi by FTP cable. Apart from the oc...

Re: Camera dual triggering

Hello, I've been experiencing 'double takes' by the cameras when triggered with the keypedal ever since I started using the pedal in combination with Spreads. There is appr. 7 sec. between the first, intended capture and the second unwanted capture on each camera. Unfortunately that's not enough to ...
