BPI-Bit : Arduino 개발환경 구축하기

BPI-Bit는 몇가지 개발 언어가 있는데 Webduino 말고도 Arduino IDE로 개발할 수 있어서, Arduino IDE 개발환경을 구축하고 간단예제를 실행해보았습니다.

1. Arduino IDE 설치

Arduino IDE (arduino-1.8.7-windows.zip)를 다운로드받고, 설치

2. arduino-esp32 다운로드

Github 저장소(espressif / arduino-esp32)에서 arduino-esp32-master.zip 파일 다운로드

3. arduino-esp32 설치

다운로드 받은 파일 arduino-esp32-master.zip을 [Arduino IDE 설치경로]/hardware/espressif/esp32에 압축 해제

4. get 명령을 관리자 권한으로 실행

[Arduino IDE 설치경로]/hardware/espressif/esp32/tools 디렉토리에서 get 명령을 관리자 권한으로 실행 실행

5. Arduino IDE를 실행하고, 메뉴[툴] > [보드] > [NodeMCU -32S] 선택
