Hay varias bibliotecas (que no librerías)

Bibliotecas: MD_MAX72XX by MajicDesigns and MD_Parola de MajicDesigns

Con esta biblioteca (que no librería) podemos definir en que posición sale cada carácter. Por ejemplo, si hacemos una secuencia de números, el 1 es mas estrecho que el 2

matrix.drawChar(x,y,char,color,bg,size);

Por ejemplo:

matrix.drawChar(0, 1, cadena[2], HIGH, LOW, 1);

#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Max72xxPanel.h>

const int pinCS = 5;
const int pinClk = 18;
const int pinDin = 23;

String cadena = "ESP32";

const int numberOfHorizontalDisplays = 4;
//const int numberOfHorizontalDisplays = 1; // retirar comentario para una sola matriz 
const int numberOfVerticalDisplays = 1;
Max72xxPanel matrix = Max72xxPanel(pinCS, numberOfHorizontalDisplays, numberOfVerticalDisplays);

void setup() {

  matrix.setIntensity(7); // Use a value between 0 and 15 for brightness
   //
  matrix.setPosition(0, 0, 0); // The first display is at <0, 0>
  matrix.setPosition(1, 1, 0); // The second display is at <1, 0>
  matrix.setPosition(2, 2, 0); // The third display is at <2, 0>
  matrix.setPosition(3, 3, 0); // And the last display is at <3, 0>
  matrix.setRotation(0, 1);    // Display is position upside down
  matrix.setRotation(1, 1);    // Display is position upside down
  matrix.setRotation(2, 1);    // Display is position upside down
  matrix.setRotation(3, 1);    // Display is position upside down


}

void loop() {

  matrix.drawChar(0, 1, cadena[3], HIGH, LOW, 1);
  matrix.write();
}

Para escribir una palabra:

Texto con Scroll:

#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Max72xxPanel.h>

//Vcc - Vcc
//Gnd - Gnd
//Din - Mosi (Pin 11)
//Cs  - SS (Pin 10)
//Clk - Sck (Pin 13)

const int pinCS = 5;
const int numberOfHorizontalDisplays = 4;
const int numberOfVerticalDisplays = 1;

Max72xxPanel matrix = Max72xxPanel(pinCS, numberOfHorizontalDisplays, numberOfVerticalDisplays);

String tape = "Texto con Scroll";  //text

const int wait = 100; // In milliseconds

const int spacer = 1;
const int width = 5 + spacer; // The font width is 5 pixels

void setup() {
   matrix.setIntensity(7); // Use a value between 0 and 15 for brightness

   matrix.setRotation(0, 1);    // Display is position upside down
   matrix.setRotation(1, 1);    // Display is position upside down
   matrix.setRotation(2, 1);    // Display is position upside down
   matrix.setRotation(3, 1);    // Display is position upside down
}

void loop() {
   for (int i = 0; i < width * tape.length() + matrix.width() - 1 - spacer; i++) {

      matrix.fillScreen(LOW);

      int letter = i / width;
      int x = (matrix.width() - 1) - i % width;
      int y = (matrix.height() - 8) / 2; // center the text vertically

      while (x + width - spacer >= 0 && letter >= 0) {
         if (letter < tape.length()) {
            matrix.drawChar(x, y, tape[letter], HIGH, LOW, 1);
         }

         letter--;
         x -= width;
      }
      matrix.write(); // Send bitmap to display

      delay(wait);
   }
