Enabling and disabling updatables
void	enable ()
	Enable this updatable: insert it into the linked list of instances, so it gets updated automatically.

	Disable this updatable: remove it from the linked list of instances, so it no longer gets updated automatically.
bool	isEnabled () const
	Check if this updatable is enabled.
void	moveDown ()
	Move down this element in the list.

Main initialization and updating methods
static void	beginAll ()
	Begin all enabled instances of this class.
static void	updateAll ()
	Update all enabled instances of this class.

Public Member Functions
void	begin () override
	Initialize this updatable.

bool	getPrevState (uint8_t col, uint8_t row)
	Get the state of the button in the given column and row.
void	setDebounceTime (unsigned long debounceTime)
	Configure the debounce time interval.
unsigned long	getDebounceTime () const
	Get the debounce time.

Constructor & Destructor Documentation

◆ MIDIButtonMatrix()

template<class BankAddress, class Sender, uint8_t NumRows, uint8_t NumCols>

MIDIButtonMatrix	(	BankAddress	bankAddress,
		const PinList< NumRows > &	rowPins,
		const PinList< NumCols > &	colPins,
		const Sender &	sender )

inlineprotected

Create a new Bankable MIDIButtonMatrix.

Parameters

bankAddress	The bankable MIDI address to send to.
rowPins	A list of pin numbers connected to the rows of the button matrix. ⚠ These pins will be driven LOW as outputs (Lo-Z).
colPins	A list of pin numbers connected to the columns of the button matrix. These pins will be used as inputs (Hi-Z), and the internal pull-up resistor will be enabled.
sender	The MIDI sender to use.
