나는 몇 개의 LED를 깜박이기 위해 PIC 18F1200을 얻으려고하고 있으며, 그렇게해서는 안된다. 저는 PIC를 2 년 넘게 16F와 18F로 프로그래밍했지만 18F1220은 이번이 처음입니다. 하나의 LED는 PortA, 7에 있으며 다른 LED는 PortB, 3에 있습니다. 인터럽트뿐만 아니라 A/D 모듈도 꺼야한다고 생각합니다. 나는 MCLR로 바뀌었고 8MHz에서 온보드 오실레이터를 사용하고있다. 데이터 시트는 나의 성경이고 나는 그것을 통해보고 있었지만, 매초마다 켜지는 것이 아니라 불규칙하게 켜지거나 꺼지는 RB3에 깜박이는 LED를 얻는 것으로 끝납니다. 누구든지 올바른 방향으로 나를 가리킬 수 있습니다. 나는 뭔가를 놓치고 있어야합니다. 모든 답장을 보내 주셔서 감사 드리며, 나는 제안을 기꺼이 테스트 해 보겠습니다.PIC 18F1220 몇 개의 LED를 깜박 거리지 만 할 수 없다

EEPROM은 읽기 및 쓰기 순서가 인터럽트 하나가 트리거되는 것을 알아보기 위해 추가되었습니다
여기에 내 현재 코드입니다. EEPROM의 내용을 보면 이것이 일어나지 않았 음을 알 수 있습니다.
감사합니다.
