# Calibrate Compass
|
|
|
|
Runs the compass calibration sequence.
|
|
|
|
```sig
|
|
input.calibrateCompass();
|
|
```
|
|
|
|
## Calibration
|
|
|
|
The calibration will ask you to draw a circle or fill the LED screen by tilting the
|
|
@boardname@.
|
|
|
|
The compass calibration is stored in memory by the @boardname@, 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 @boardname@ 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 @boardname@.
|
|
|
|
## Example
|
|
|
|
This example runs the calibration when the user presses **A+B** buttons.
|
|
|
|
```blocks
|
|
input.onButtonPressed(Button.AB, () => {
|
|
input.calibrateCompass();
|
|
})
|
|
```
