Constructors​

BluetoothSerialJoystick()​

Default constructor that initializes joystick values to zero.

BluetoothSerialJoystick(double rot, double mag)​

Parameterized constructor for specifying initial joystick values.

Parameters:

  • rot: Initial rotation value in degrees.
  • mag: Initial magnitude or distance from the center.

Methods​

void updateValues(double rot, double mag)​

Updates the joystick's rotation and magnitude values.

Parameters:

  • rot: New rotation value in degrees.
  • mag: New magnitude or distance from center.

double getX()​

Retrieve the joystick's horizontal (X-axis) position.

Returns: the x position of the joystick, ranging from -1 to 1.

double getY()​

Retrieve the joystick's vertical (Y-axis) position.

Returns: the y position of the joystick, ranging from -1 to 1.

double getRotationDeg(double offset = 0)​

Retrieve the joystick's rotation in degrees.

Parameters:

  • offset: (Optional) Degree offset to adjust the returned value.

Returns: The rotation of the joystick in degrees, adjusted by the offset.

double getRotationRad(double offset = 0)​

Retrieve the joystick's rotation in radians.

Parameters:

  • offset: (Optional) Radian offset to adjust the returned value.

Returns: The rotation of the joystick in radians, adjusted by the offset.

double getMagnitude()​

Retrieve the joystick's distance from the center.

Returns: The magnitude of the joystick's position, with a maximum of 1.00.
