Member Enumeration Documentation

◆ Event

enum Event
Enumerator
None 

Nothing changed.

PressStart 

The button was just pressed.

ShortPressRelease 

The button was released after a short press.

LongPress 

The button has been pressed for some time.

LongPressRelease 

The button was released after a long press.

MultiPress 

The button was pressed in quick succession of the previous release.

MultiPressDone 

The button has been released for long enough to rule out another MultiPress.
