/**
|
|
* Use a rate gyro to return the robots heading relative to a starting position.
|
|
*
|
|
* The AnalogGyro class tracks the robots heading based on the starting
|
|
* position. As the robot rotates the new heading is computed by integrating
|
|
* the rate of rotation returned by the sensor. When the class is instantiated,
|
|
* it does a short calibration routine where it samples the gyro while at rest
|
|
* to determine the default offset. This is subtracted from each sample to
|
|
* determine the heading. This gyro class must be used with a channel that is
|
|
* assigned one of the Analog accumulators from the FPGA. See AnalogInput for
|
|
* the current accumulator assignments.
