class Bankable::MIDIButtonMatrix< BankAddress, Sender, nb_rows, nb_cols >

MIDIButtonMatrix.

Todo:: Documentation

See also: AH::ButtonMatrix

Template Parameters

BankAddress	The bankable address object containing the addresses of all buttons, as well as a reference to the bank this element belongs to.
Sender	The MIDI Sender class.
nb_rows	The number of rows of the button matrix.
nb_cols	The number of columns of the button matrix.

Definition at line 29 of file Bankable/Abstract/MIDIButtonMatrix.hpp.

Constructor & Destructor Documentation

◆ MIDIButtonMatrix()

MIDIButtonMatrix	(	const BankAddress &	bankAddress,
		const PinList< nb_rows > &	rowPins,
		const PinList< nb_cols > &	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.
