Congrats! Gotta love FOSS and the variety of options it offers :-)
There are several implementations of this, including Miller's gpio, and pd-l2ork's disis_spi and disis_gpio (which are also compatible with pd-vanilla). disis_spi gives you 8 channels of mcp3008 connectivity, and disis_gpio gives you all the GPIO functionality from wiringpi, including both hw and sw pwm and the ability to side-step wiringpi's dubious requirement to exit the program if an error is encountered. They build automatically for Raspberry Pi builds of pd-l2ork (./tar_em_up.sh -R), but can be also built manually by going into <git_mirrored_folder>/l2ork_addons/raspberry_pi folder. These will be presented at NIME early next week. Cheers!

Hi all,
I've recently made this external to access the GPIO and the mcp3008 (or mcp3004) chip in the raspberry pi. They are standalone externals based on WiringPi (http://wiringpi.com/). Everything is in C so they should be reasonably fast.
To get the code, binaries and help files go to:

All best,
