The GetSmartDashboardType() function defined by GyroBase was returning the correct "Gyro", but the overrides in AnalogGyro and ADXRS450_Gyro were incorrectly changing this, resulting in SmartDashboard not recognizing these as being gyros. Additionally, AddSensor in the C++ AnalogGyro was setting the name to Gyro rather than AnalogGyro. Change-Id: Ib2e31cd2712cc2bc26c8082ed760175d0ee80fb6

* Use a rate gyro to return the robots heading relative to a starting position.
|
|
* The Gyro 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.
|
|
*
|
|
* This class is for gyro sensors that connect to an analog input.
