The zip file contains the information needed to create a fully functional General Purpose Sensor Platform (GPSP).
Arduino program and environment, STL files for the box, assembly instruction images, a Java test program and a Max 5 patch is included.
All sources are used on windows 7.
Max5 and Java is not required to use the device, but the sources provide some example code that can be used to access the device.
Max can be downloaded from http://cycling74.com/
Java can be downloaded from http://www.java.com/
A paper about the GPSP has been published at NIME 2013 (pdf).
