To make application development and programming the STRUIX stack easier, a tutorial on Multiprogramming has been added. Here your will find instructions and downloads to enable programming the entire stack - or just a single CPU.
Also included in the download section is a version of Ruby::XBee, with added features, specifically tailored to STRUIX. Ruby::XBee is a set of ruby scripts used to configure XBee radios on the fly.
It's #4 in the STRUIX Projects list on the navigation bar.
