At this point there are two known issues w/the Java code that's in the repository:

- The IMU and IMUAdvanced classes use @Override, which is not supported in J2ME / Java 1.3

- The IMUAdvanced class uses atan2() and atan(), which are not present in the math library in the J2ME.

We have a test app on the PC that we tested the java IMUProtocol class with, but that was with Java 1.7; the IMU and IMUAdvanced classes are ported from our original C++ code base, and haven't been fully tested on the robot yet.

For the first item, it's a simple task to comment out the override.

For the second item, a member of Team 11 is adding support for the inverse trig functions.

I'll post a note to this forum when we get the java classes fully tested and checked in, this should happen over the next few weeks.

Please let me know if you have any more questions.

I got them both working last night by removing the @Override line and switching from Math to MathUtils. We purchased a nav6 on Saturday and as soon as we get it I'll test everything as thoroughly as possible.
