I'm trying to program UDOO in java using rxtxcomm ....pratically impossible ... When I install rxtxcomm library for ARM I have a problem ,Arduino IDE stop to runs , NEtbeans stops to runs I think there is not possible to use UDOO with java and serial communication . Udoobuntu , ...the problemts are there is not enaugh documentation and not support And don't know what to say anymore I am very disappointed of all
You can look my tutorial eclipse-with-udoobuntu-and-arduino-communication-tutorial-t1512.html Also, I advice to you use Python.
I had already try this way but I got errors .....now I want to follow your tutorial again , installing eclipse from lubuntu donwload center
