Enable led when matrix button pressed.

[Basiliadis]

Hello all,

can you please tell me how can i activate leds ON/OFF when a matrix button is pressed?
I mean how can i assign the matrix button address or matrix button pin to the code?

Thank you very much.

Code:

#include <Control_Surface.h>

USBMIDI_Interface midi;

// The note numbers corresponding to the buttons in the matrix
const AddressMatrix<4, 3> addresses {{
{1, 2, 3, 4},
{5, 6, 7, 8},
{9, 10, 11, 12},
}};

NoteButtonMatrix<4, 3> buttonmatrix {
{10, 16,14, 15,}, // row pins
{7, 8, 9}, // column pins
addresses, // address matrix
Channel_1, // channel and cable number
};

void setup() {
Control_Surface.begin();
}

void loop() {
Control_Surface.loop();
}

You can use the NoteButtonMatrix::getPrevState(col, row) function.

Hello Pieter,

yes of course....i will not do it again.
I solve the problem with Shift register 74HC595 and leds works perfect.
I have a problem with the last button on Multiplexer (pin15) that returns two different values when press it...
I will try to solve this too.
