Raspberry Pi Piface Addon
Sorry, this documentation is currently incomplete. I went through a bit of trial and error to get things going myself, and some of the dependencies aren't listed.
Interface to the Raspberry Pi Piface board using Node.js. This addon shouldn't require any sudo or root privileges to run, as long as your user is in the "spi" group on your Pi.
Everything piface, availble here. Follow the "C" library installation.
You'll need Node.js, of course. It's not quite as easy to install on a Raspberry Pi as it is on other platforms, so you might need to dig around to find the newest available version for the Pi's architecture. At the time I write this, the latest available packaged build for Raspberry Pi is v0.10.17.
Build tool for Node.js addons. You can find it here.
$ node-gyp configure$ node-gyp build
Something along these lines should do it:
var pfio = require'/path/to/build/Release/pfio';pfioinit;pfiodigital_write01;pfiodeinit;
