Is there a QR code reader for the Nokia N810?

Yes, derf/tterribe has written some code, it's available in the maemo-barcode repo along with a test application: https://garage.maemo.org/plugins/scm...=maemo-barcode

I plan to add this functionality into the barcode reader I've been developing (https://garage.maemo.org/plugins/scm...=maemo-barcode), and can compile the test app for you this afternoon so you can try it out.

thanks. can you pm me when it's ready?

Oops, sorry, ran out of time yesterday. Am away until Wed, but will sort it out when I get back if someone else hasn't compiled it already. Si

I've tried your maemo-barcode app.. amazing! Can't wait to see this working for QR-codes!

It's a pity the camera on the N810 faces forward not back, as I guess that makes apps like this harder to use.

Yes it is a shame with the N810, the N800 works well though (though I've not set the image to flip when the camera is twisted to face forwards) and the "N900" will (we're pretty sure) have two cameras, with one facing either way.

Just got back this evening, and am pretty tired so I'll get the QR code stuff compiled tomorrow.

QR code decoder here: http://people.xiph.org/~tterribe/tmp/qrreader

And some notes about it (quoted directly from IRC):

<derf> And... for some reason this binary is segfaulting when the x86 one did not.
Well, reverting to current svn still does, so it's not a new regression anyway.
<derf> Only happens on ~a dozen images out of 200.
<derf> I don't have time to track it down right now, but I can hand you the binary as-is.

<lardman> ok cool, will pass that on
<derf> Note that that's for PNG input only, and unless you have a version of iconv that supports SJIS (and maybe CP437), you'll have trouble decoding codes with data in those character sets.
<lardman> ok
<derf> (it'll still produce output, just not converted to UTF-8)
<lardman> ok

...snip...

<derf> Oh, I remember what this segfault is.
libpng on the tablets is borken.

Before things like QR and dtmx codes can realistically be added to the mix, we probably need to develop some fast recognition codes so we can decide if it's worth trying the relevant full decoder (QR and dtmx decoders are slow compared with the 1D decoder).

Bumping this topic to see if it will be ported to the N900? Also, has there been any progress toward QR codes? I got used to sending links from Mozilla to my N95 with the QR plugin, and being able to paste 1D codes into a google search for comparison shopping might be useful.
