#define END_CS_NAMESPACE
#define BEGIN_CS_NAMESPACE
A class for reading and debouncing buttons and switches.
Definition: Button.hpp:18
State update()
Read the button and return its new state.
Definition: Button.cpp:13
State
An enumeration of the different states a button can be in.
Definition: Button.hpp:48
@ Rising
Input went from low to high (0,1)
Definition: Button.hpp:52
@ Falling
Input went from high to low (1,0)
Definition: Button.hpp:51
void invert()
Invert the input state of this button (button pressed is HIGH instead of LOW).
Definition: Button.cpp:11
State getState() const
Get the state of the button, without updating it.
Definition: Button.cpp:34
void begin()
Initialize (enable the internal pull-up resistor).
Definition: Button.cpp:9
A super class for object that have to be updated regularly.
Definition: Updatable.hpp:173
Definition: Chords.hpp:16
A type-safe utility class for saving a MIDI address consisting of a 7-bit address,...
An abstract class for momentary push buttons that send multiple MIDI events.
void setAddressUnsafe(MIDIAddress address)
Set the MIDI address.
AH::Button::State getButtonState() const
std::unique_ptr< const IChord > newChord
MIDIChordButton(pin_t pin, MIDIAddress address, Chord< N > chord, const Sender &sender)
Construct a new MIDIChordButton.
MIDIAddress getAddress() const
Get the MIDI address.
void begin() final override
Initialize this updatable.
std::unique_ptr< const IChord > chord
void setChord(Chord< N > chord)
Change the chord. Can be used safely while the push button is pressed.
void update() final override
Update this updatable.
PrintStream library
Definition: Array.hpp:14
uint16_t pin_t
The type for Arduino pins (and ExtendedIOElement pins).
