/**
|
|
* This file illustrates the concept of calibrating a MR Compass
|
|
* This code assumes there is a compass configured with the name "compass"
|
|
*
|
|
* This code will put the compass into calibration mode, wait three seconds and then attempt
|
|
* to rotate two full turns clockwise. This will allow the compass to do a magnetic calibration.
|
|
*
|
|
* Once compete, the program will put the compass back into measurement mode and check to see if the
|
|
* calibration was successful.
|
|
*
|
|
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
|
|
* Remove or comment out the @Disabled line to add this opmode to the Driver Station OpMode list
