Hmmm... spomwii's photos may be focusing correctly, but mine definitely aren't, at least not consistently. Any ideas about what might be causing this? I need to pack up the kit for the conference on Wednesday, and I'd like to show off something OCR-able.

Can I go into CHDK and force autofocus off somehow, or does spreadPi overwrite those settings?

The default values are in a file named config.yaml. You can find the file in the directory/home/spreads/.config/spreads . These are the default settings:

Does all of the confuguration information that is generated when you run "spread configure" end up in config.yaml? I noticed there doesn't seem to be any kind of "autofocus" switch in there.

Huh, I don't see anything in there relating to focus at all. This is probably something we need to bring up with Johannes. He is currently on vacation, I understand, returning after the 28th. Can't wait to have you up and running so we have a few more people with working setups... we really need to build a critical mass of people that can help with all these teething issues.

spomwii, the issue with footpedal-induced shots not being registered by the counter is due to a bug in the event-handling code that has I've already fixed in my not yet published postprocessing branch. I will merge it once I am home from my vacation and added some tests :)

Ah, thanks :)
I moved the pedal directly to the pi again last night, and then it worked as normal again. :)

I am not sure if this is relevant any more but I remember when I bought the kit from Mark and was using the keypedal script, it was important to set these settings on the cameras: https://github.com/markvdb/diybookscann ... ettings.md

What is "not relevant anymore"?
The entire project?
Thanks,

Has anybody of you already got hand on a raspberry pi 2?

Would be interesting to know how it can handle postprocessing.
