M5Stack M5Paper · File : m5paper_gpio_led_blink.ino · Language : C++ · Use case : Faire clignoter la LED embarquée pour tester la configuration GPIO de base.

Minimalist example to verify GPIO functionality via the integrated red LED.

Uses the M5EPD library. The red LED is connected to GPIO 40. Compile with the 'M5Paper' board selected in the Arduino IDE. Ensure the USB cable is connected for power.

#include <M5EPD.h>

M5EPD m5epd;

void setup() {
  // Initialisation du M5Paper
  m5epd.begin();
  m5epd.updateBuffer();
  
  // Configuration de la LED rouge (GPIO 40 sur M5Paper)
  pinMode(40, OUTPUT);
}

void loop() {
  digitalWrite(40, HIGH); // Allumer la LED
  delay(500);
  digitalWrite(40, LOW);  // Éteindre la LED
  delay(500);
