Extraer direccion de una matrix
Hola Peter. He cobstruido una matrix de notas de 4x4, con 4 bancos, funciona perfecto con el ejemplo que trae la libreria, sin embargo me gustaria poder visualizar en un oled la nota que he presionado, he intentado obtener las direcciones de la matrix pero no me ha sido posible, sibpudieras orientarme un poco te lo agradeceria. Un saludo y abrazo desde España.
You can check which buttons are pressed using the NoteButtonMatrix::getPrevState() method. The addresses are private, but you could add a getter for them.
template <class Sender, uint8_t nb_rows, uint8_t nb_cols>
class MIDIButtonMatrix : public MIDIOutputElement,
public AH::ButtonMatrix<nb_rows, nb_cols> {
...
public:
uint8_t getAddress(uint8_t row, uint8_t col) const { return addresses[row][col]; }
private:
AddressMatrix<nb_rows, nb_cols> addresses;
...
};
Hola. He estado tratando y tratando y no me ha salido, soy aficionado por lo que no se mucho. Lo mas cercano que me salio fue esto. Solo que en el monitor serie me salen caracteres que no se de donde salen, bien este es lo que hice

It's not clear to me what you're trying to do. Please explain what you expect the code to do, and what it actually does. If you get output on the serial monitor that you don't understand, post it here as well.

Mi idea es que cuando presione una tecla de la matriz me muestre en una pantalla el numero de nota, el problema que he encontrado es el no poder obtener el numero de tecla presionado, con el codigo que he publicado funciona a medias, puesto que en el monitor serie me salen valores como estos >? >? 60, siempre me sale esto >? >?, el numero me sale al final pero no puedo meterlo en una variable para mostrarlo en cualquier pantalla. Me gustaria que muestre solo el numero, es decir la nota en nunero digamos 60,61,62,63,64..... No logre incluir o llamar al getPrevState(), me tira error de que no pertenece al notebuttonMatrix
The output you're seeing in the Serial monitor is the MIDI output. The USBMIDI_Interface class sends serial data if your board doesn't support MIDI over USB, but the MIDI data is not text, so you can't read it in the Serial monitor. You could try using USBDebugMIDI_Interface to see the MIDI messages in the serial monitor.
