피노키오 13 교육부 김송현
Firmata와 Processing
▪Firmata: 컴퓨터-아두이노 간 통신 프로토콜
▪컴퓨터로 아두이노를 직접 조작할 수 있다
▪ 강좌에서는 Processing을 사용하지만, 다른 곳에서도 사용 가능!
개발환경 구성
▪아두이노 보드에 Firmata 프로그램 올리기
▪ 파일->예제->Firmata->StandardFirmata->업로드
▪프로세싱에 아두이노 라이브러리 설치하기
▪ Sketch->Import Library->Add Library
▪ 검색창에 Arduino 검색하고 Arduino(Firmata) 인스톨
9th Program:
▪13번 LED를 1초에 한 번씩 깜빡이게 하는 프로그램
// 라이브러리 추가
import cc.arduino.*;
import processing.serial.*;
Arduino board; // 아두이노 객체 생성(이름은 아무거나 괜찮다)
9th Program:
void setup() {
board = new Arduino(this, “COM12”, 57600);
board.pinMode(13, Arduino.OUTPUT);
}
9th Program:
void draw() { // loop 역할
board.digitalWrite(13, Arduino.HIGH);
delay(1000);
board.digitalWrite(13, Arduino.LOW);
delay(1000);
}
9th Program:
▪board = new Arduino(this, “COM12”, 57600);
▪ 객체 초기화 작업
▪ 두 번째 인자는 연결 포트, 세 번째 인자는 baud rate 입력
▪기타 코드들
▪ (객체 이름).(아두이노 함수) 식으로 코드를 작성
▪ 나머지는 아두이노 코드와 똑같이 작성하면 된다
▪ delay()는 객체 이름을 붙이지 않고 사용 가능
9th Program: Going Further
▪Firmata를 사용하는 이유는 무엇인가요?
▪ 아두이노 보드에 바로 프로그램을 업로드하지 않고도, 원하는 언어를 통하여
바로 아두이노를 동작시킬 수 있다
▪ 아두이노의 문제점(작은 용량, 느린 속도)를 컴퓨터로 넘겨서 아두이노 보드
자체는 입/출력에만 전념할 수 있게 한다->성능 향상!
▪ ex) 아두이노에서 처리할 수 없는 큰 규모의 연산은 컴퓨터에서 진행
