Interfacing a digital compass with the RC
As an off-season project, my team wants to add a digital compass to this year's robot. We are currently interested in the one featured here: http://www.robot-electronics.co.uk/s...CMPS032004.htm

I was wondering if anyone has experience with this or other digital compasses or if anyone has specific advice for getting data from it with the robot controller.

The documentation says it can use PWM and I2C outputs (outputs on the compass, meaning inputs on the RC). Which of these would I want to use? Which pins would I connect it to on the controller?

Also, we're looking for something that can handle spinning around pretty quickly without getting out of whack. How quickly does this compass update?
