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.

Definition at line 32 of file MultiPurposeButton.hpp.

◆ update()

Event update ( )
inline

Read the button state and return the Event (if any).

Definition at line 35 of file MultiPurposeButton.hpp.

◆ getMultiPressCount()

uint8_t getMultiPressCount ( ) const
inline

Get the number of times the button was pressed in quick succession (after MultiPressDone), this is the final count.
