Using an SPI Gyro

It's a 9-axis sensor (3 gyros, 3 accelerometers, 3 magnetometers) with a motion processor, and it provides accurate, low-drift readings for use in driving straight, as well as field-centric drive. Hundreds of these boards are in use by FIRST FRC teams, and it includes libraries for LabView, Java and C++ as well as examples and other documentation.

I have not gone ahead and bought the ADXRS450 so I'll go ahead and take a look at that! Reading on the website though, it mentioned that the device plugs straight into the MXP port on the roborio. Is it possible to get an extension cord out of the MXP port so I can mount this device somewhere else in the robot? The roborio is at quite the awkward angle right now, and I believe it's actually butted against the battery when in operation. Thank you for the recommendation though!

We used the ADXRS453 this year and wrote a class in Java to interface with it.

I've described how to use the class in another thread on CD
See the post here: http://www.chiefdelphi.com/forums/sh...94&postcount=4

The port over to C++ should be pretty straight forward.
