Description
Description-Separate-1IN 으로 배열 선언된 접점은 계속 읽어서 Serial 로 출력 합니다.
OUT 으로 배열 선언된 접점은 Serial Interrupt 를 통해 프로토콜 확인 후 출력합니다.
제어 명령은 2자리 Digital IO 와 _ 언더바, 세자리 On Off 커맨드로 이뤄 집니다. On 은 스페이스 넣어 주셔야 합니다.
응답은 특정 프로토콜에 맞춰 나오며, INPUT 접점도 마찬가지로 프로토콜에 맞춰 출력합니다.
명령 응답 STX + ADDR + DigitalIO + State +ETX +CR + LF
입력 응답 STX + ADDR + DigitalIO 의 상태값...... +ETX +CR +LF
추가로.. ChatGPT 틀린부분 정말 잘 찾네요. 사랑합니다 ChatGPT.

Description-Separate-2How to Use
How-Separate-1Arduino Mega 2560 에 ino 파일 업로드 후 Serial 통신 예제로 통신 제어가 되는지 확인 합니다.
확인을 위해 13번 LED 가 OUTPUT으로 선언되어 있습니다.
