Constructor & Destructor Documentation

◆ MIDIButtonMatrix()

template<class Sender, uint8_t NumRows, uint8_t NumCols>

MIDIButtonMatrix	(	const PinList< NumRows > &	rowPins,
		const PinList< NumCols > &	colPins,
		const AddressMatrix< NumRows, NumCols > &	addresses,
		MIDIChannelCable	channelCN,
		const Sender &	sender )

inlineprotected

Construct a new MIDIButtonMatrix.

Parameters

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.
addresses	A matrix containing the address corresponding to each button.
channelCN	The MIDI channel and optional cable number for all buttons.
sender	The MIDI sender to use.
