[ESP32S3-SM] ESP32S3 개발환경 설정 (Arduino 만들기)

ESP32S3 개발환경은 여러가지가 있지만 간단하고 많이 쓰이는 ArduinoIDE에서 세팅을 해 보자

 

우선 최신 ESP32 Aduino Boards Meanager URL 을 설정한다. 
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json

 

 

Board Manager 에서 "ESP32S3 Dev Module"을 선택한다.

기본 예제로 ESP32S3 SM 보드에 실장되어 있는 LED를 제어 해 보자.

#define LED_PIN1    18

void setup() {
  Serial.begin(115200);
  pinMode(LED_PIN1, OUTPUT);
}

void loop() {
  digitalWrite(LED_PIN1, 1);
  delay(100);
  digitalWrite(LED_PIN1, 0);
  delay(100);
}
