Calibrate Compass

Runs the compass calibration sequence.

input.calibrateCompass();

Calibration

The calibration will ask you to draw a circle or fill the LED screen by tilting the @boardname@.

If you are calibrating or using the compass near metal, it might confuse the @boardname@.

Example

This example runs the calibration when the user presses A+B buttons.

input.onButtonPressed(Button.AB, () => {
    input.calibrateCompass();
})
