Proposed Addon : ofxGPIO

[bakercp]

ofxGPIO to allow direct access general purpose input / output (GPIO) pins on the RPI and other embedded linux systems.

Could work nicely with the T-COBBLER or others: http://www.adafruit.com/blog/2012/11/16/new-product-adafruit-pi-t-cobbler-breakout-kit-for-raspberry-pi/

What would be the most generic approach to this?

I started working on this sometime ago on a beaglebone till it broke and had to return it, i think the best would be to replicate ofArduino api

Have tried the wiringPi library as well, seems to work flawless.

heads up - while looking at /etc/modprobe.d/raspi-blacklist.conf I found these entries which could be problematic

# blacklist spi and i2c by default (many users don't need them)

blacklist spi-bcm2708
blacklist i2c-bcm2708

[bakercp]

Indeed! I believe the adafruit distro has all of that stuff enabled.

Closing this, since it isn't an "issue" and moving this here: https://github.com/openFrameworks-RaspberryPi/openFrameworks/wiki/Arm-Linux-Wishlist
