본문
코드 두개를 합쳐서
하나는 소프트웨어 시리얼로 연결하고
하나는 하드웨어 시리얼로 연결했는데
와이파이를 연결한 소프트웨어 시리얼만 작동되고
하드웨어에 연결된 lcd 는 화면만 뜨고 전혀 작동을 하지않습니다. 뭐가 문제일까요ㅜ
혹시 하드웨어시리얼과 소프트웨어시리얼은 동시에 작동이 불가능한가요?
확인해보니 loop 쪽이 제대로 안돌아가더라구요ㅠㅠ

넣어봤는데 오류가 뜹니다ㅠㅠ setup 문에 넣는게 아닌가요?? 소프트웨어 시리얼 날씨정보를 받아오는 루프가 한시간에 한번 동작되도록 설정하였는데 혹시 그것때문에 하드웨어시리얼이 안돌아가는건 아닌가요? ㅜㅜ
