Sorry for the slow reply. We'd be happy to.
We are trying to get this to work right now, but are running into build problems just trying to test out the DataMonitor example. We followed the steps at
http://www.pdocs.kauailabs.com/navx-...ibraries/java/ (three sets of eyes checked this) and are still getting an error:
...navx-mxp\java\examples\DataMonitor\src\org\usfirst\frc\ team2465\robot\Robot.java:3: error: package com.kauailabs.navx.frc does not exist
[javac] import com.kauailabs.navx.frc.AHRS;
Is there anything else we should check? This seems like a really basic thing. We've now spent two full meetings trying to figure it out. The navx-mxp jar path is right there in our Java Build Path, but its like it's invisible and gets letf out during the build.
