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 micro:bit.

The compass calibration is stored in memory by the micro:bit, so next time you press the reset button or remove and replace the power the calibration will be remembered.

When you flash a new program to your micro:bit via USB, this memory is cleared so you will have to re-calibrate it.

If you are calibrating or using the compass near metal, it might confuse the micro:bit.

Example

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

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