Can anyone recommend a good tactic (that doesn't involve modifying the navX source code) to convert the yaw output from a range of -180 to 180 (i.e. modulo 360) to an accumulated total rotation? All of the approaches we can think of require an assumption of what a maximum realistic turn rate is, and we'd like to avoid that if possible. I'm confident that we're not the only team encountering this challenge.

Edit: it appears that the modulo conversion is performed on board the navX, so there's no way to tweak the LabVIEW library to get the "true" total rotation. Even in looking at the navX source, it looks like the modulo conversion might be getting performed by the Invensense libraries.

Edit2: it also appears that the on-the-fly recalibration does some "interesting" things to the rollover point of the output. That's going to surprise some folks, I think. We too will be looking for ways to disable that feature, if that is indeed the cause of the behavior we are seeing.
