CCButtonMatrix< NumBanks, NumRows, NumCols > Class Template Reference

#include <MIDI_Outputs/ManyAddresses/CCButtonMatrix.hpp>

Detailed Description

template<setting_t NumBanks, uint8_t NumRows, uint8_t NumCols>
class Bankable::ManyAddresses::CCButtonMatrix< NumBanks, NumRows, NumCols >

A class of MIDIOutputElements that read the input from a matrix of momentary push buttons or switches, and send out MIDI Control Change events.

A value of 0x7F is sent when a button is pressed, and a value of 0x00 is sent when a button is released.
Crude software debouncing is implemented by limiting the refresh rate.

Template Parameters
NumBanksThe number of variants/alternative addresses the element has.
NumRowsThe number of rows of the matrix.
NumColsThe number of columns of the matrix.

◆ CCButtonMatrix()

template<setting_t NumBanks, uint8_t NumRows, uint8_t NumCols>
CCButtonMatrix ( const Bank< NumBanks > & bank,
const PinList< NumRows > & rowPins,
const PinList< NumCols > & colPins,
const Array< AddressMatrix< NumRows, NumCols >, NumBanks > & controllers,
const Array< MIDIChannelCable, NumBanks > & channelCNs,
const DigitalCCSender & sender = {} )
inline

Create a new Bankable CCButtonMatrix object with the given pins, controller numbers and channel.

Parameters
bankThe bank to add this element to.
rowPinsA list of pin numbers connected to the rows of the button matrix.
These pins will be driven LOW as outputs (Lo-Z).
colPinsA 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.
controllersA list of 2-dimensional arrays of the same dimensions as the button matrix that contains the MIDI Controller number of each button. [0, 119]
channelCNsThe a list containing the MIDI channels [Channel_1, Channel_16] and Cable Numbers [Cable_1, Cable_16].
senderThe MIDI sender to use.
