안녕하세요...
다음과 같이 동작 Fllow에 맞춰 코드을 작성해보았는데 현재 모듈이 없어 확인이 어렵습니다.
모듈이 오기 전 작성한 코드에 오류가 있는지 확인하고 싶은데 조언 부탁드립니다.
 
1. PD7이 Low일 때 온도와 관계없이 팬 동작 x
2. PD7 High가 입력되면
3. 온도에 따라 팬이 동작(25도 미만이면 duty60%, 25도~27도 이면 duty 78%,27도 이상이면 100%)
4. PD7 High 입력 후 6초 이전까지 PD3,PD5 Low PD6 High
4. 6초 이후 PD3,PD5 High PD6 Low(PD7이 Low될 때까지 유지)
5. flowrate가 0이면 PD1 High, Flowrate가 0이 아니면 PD1 Low (PD7이 High 일때)
 
첨부된 파일은 온도테이블입니다.
