/* Basic example code for MAX7219 LED dot matrix display with Arduino. More info: https://www.makerguides.com */
// Include the required Arduino libraries:
#include "MD_Parola.h"
#include "MD_MAX72xx.h"
#include "SPI.h"
// Define hardware type, size, and output pins:
#define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW
#define MAX_DEVICES 4
#define CS_PIN 3
// Create a new instance of the MD_Parola class with hardware SPI connection:
//MD_Parola myDisplay = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
// Setup for software SPI:
#define DATA_PIN 2
#define CLK_PIN 4
MD_Parola myDisplay = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);
void setup() {
// Intialize the object:
myDisplay.begin();
// Set the intensity (brightness) of the display (0-15):
myDisplay.setIntensity(5);
// Clear the display:
myDisplay.displayClear();
