Hi all,
We've been after some sensors for motion detection on the RPi and Martin Peach spotted these (thanks again Martin!)

They're fairly new and I've not been able to find anything about anyone making use of them on the RPi as of yet (though after posting a question on the RPi forum I did note that Farnells stock went from 48 the 4 in three days, so maybe something soon eh?:).
I've got absolutely no idea what I'm doing with this so could do with some 'hand-holding'.
What I would much prefer would be to keep everything within Pd if possible...
1st off, and possibly dumb question - do we need [hid]? - My previous experience with xbee sensors did, so this is why I'm asking.
[hid] is for USB devices so no.
There are a few mentions of using python to get the data received on the Pi and then OSC'ing that into Pd but Miller mentioned on another thread "gpio on the raspberry pi from within pd ?" about writing an external to keep it within Pd. Any news/progress/tips on that front?
http://www.gigamegablog.com/2012/11/04/beaglebone-coding-101-i2c/ talks about using i2c and python with the beaglebone which is a similar machine. It even uses code written for the Pi (https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code). Using python ans OSC seems to be the easiest way to get started.
In the same thread Charles Goyard seems to have it working with [textfile], which seems far too simple (I'd very much like that if that was the case)
The sensor transmits the data as i2c but I haven't found anything in the archives particularly about anyone translating i2c directly in Pd yet?
I just got one of these and I'm going to try it with an arduino since the i2c there is easier to use. The arduino can talk to Pd using [comport].
Martin
We're going to fire the sensors up and see what happens in an hour or so and then come back to it tonight for a proper session so any and all pointers gratefully accepted.
I'll be back to let you know our 1st results soon.
Cheers,
Julian
