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,
