/**
|
|
* {@link SensorIMUOrthogonal} shows how to use the new universal {@link IMU} interface. This
|
|
* interface may be used with the BNO055 IMU or the BHI260 IMU. It assumes that an IMU is configured
|
|
* on the robot with the name "imu".
|
|
* <p>
|
|
* The sample will display the current Yaw, Pitch and Roll of the robot.<br>
|
|
* With the correct orientation parameters selected, pitch/roll/yaw should act as follows:
|
|
* <p>
|
|
* Pitch value should INCREASE as the robot is tipped UP at the front. (Rotation about X) <br>
|
|
* Roll value should INCREASE as the robot is tipped UP at the left side. (Rotation about Y) <br>
|
|
* Yaw value should INCREASE as the robot is rotated Counter Clockwise. (Rotation about Z) <br>
|
|
* <p>
|
|
* The yaw can be reset (to zero) by pressing the Y button on the gamepad (Triangle on a PS4 controller)
|
|
* <p>
|
|
* This specific sample assumes that the Hub is mounted on one of the three orthogonal planes
|
|
* (X/Y, X/Z or Y/Z) and that the Hub has only been rotated in a range of 90 degree increments.
|
|
* <p>
|
|
* Note: if your Hub is mounted on a surface angled at some non-90 Degree multiple (like 30) look at
|
|
* the alternative SensorImuNonOrthogonal sample in this folder.
|
|
* <p>
|
|
* This "Orthogonal" requirement means that:
|
|
* <p>
|
|
* 1) The Logo printed on the top of the Hub can ONLY be pointing in one of six directions:
|
|
* FORWARD, BACKWARD, UP, DOWN, LEFT and RIGHT.
|
|
* <p>
|
|
* 2) The USB ports can only be pointing in one of the same six directions:<br>
|
|
* FORWARD, BACKWARD, UP, DOWN, LEFT and RIGHT.
|
|
* <p>
|
|
* So, To fully define how your Hub is mounted to the robot, you must simply specify:<br>
|
|
* logoFacingDirection<br>
|
|
* usbFacingDirection
|
|
* <p>
|
|
* 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.
|
|
* <p>
|
|
* Finally, choose the two correct parameters to define how your Hub is mounted and edit this OpMode
|
|
* to use those parameters.
