My understanding is that [gpio] is based on wiringPi https://projects.drogon.net/raspberry-pi/wiringpi/ My understanding also is that wiringPi is the best of the bunch (in C, most direct access to the various pins, well written, most widely made use of, etc.) There's a couple of nice utilities in wiringPi that could be extra objects for a PiLib, including a nice gpio swiss-army-knife type thing as well as i2c control.
If anyone's got the skills and some time (I don't have either currently) it could be a really useful addition for Pi and Pd.
All the best,
Julian

Hello all, I came across Miller's gpio external and have been able to use it successfully. I'm now wondering what it would take to implement i2c control from within Pd also, in order to work with accessories/breakouts like: -4 x ADC over i2c: https://www.adafruit.com/products/1085 -16 x servo/pwm over i2c: http://www.adafruit.com/products/815
ladyada provides the necessary software and hardware...
have anyone given this some thought?

Hey Jaime,
My plan is to document the process when the piece is finished (hopefully within a week or so) and bundle the documentation with an image of the raspbian RPi OS - more than likely up on archive.org.
I'll definitely let you know when it's done.
BTW - Martin's not in on this thread (is now)
Cheers,
Julian

Indeed the help patch is in that thread and I attach it here as well. the source is here: http://crca.ucsd.edu/~msp/syllabi/206.13w/pi-externs.tgz
Martin, Julian, do you plan to do some documentation / tutorial of the work you're doing? I haven't followed the thread in detail, but it looks like you guys have accomplished quite a bit of stuff...
best,
J

Hey Ali,
Yes indeed... well, kind of.
For my project we have some C code that Martin Peach put together that pipes the sensor data into Pd via UDP.
Works really very well so have stalled on [gpio]. I did get data in and out of [gpio] without any issues though and Jaime improved the help patch considerably (well - he wrote one!)
My memory is that Jaime's help patch is on the thread you've linked to and here's the rather lengthy one between Martin and I - watch out though there's lots of it (70+ posts currently).

All the best and give us a shout if there's anything specific,
Julian
