스위치 1은 하강에서 스위치 2는 상승에서 각각의 인터럽트 발생시켜 세그먼트로 왼쪽 오른쪽 2자리씩 버튼을 누를때마다 카운트가 올라가는 코드를 짜고있는데
C:/Users/ProDesk/STM32CubeIDE/workspace_1.14.1/asdasd/Debug/../Core/Src/stm32f4xx_it.c:205: multiple definition of `EXTI0_IRQHandler'; ./Core/Src/main.o:C:/Users/ProDesk/STM32CubeIDE/workspace_1.14.1/asdasd/Debug/../Core/Src/main.c:185: first defined here
라는 오류와 함께 진행이 안되어 삭제 시키고 진행시키면 작동은되는데 세그먼트가 안나오면 핀을 뽑으면 나오긴하는데 오류가납니다 무슨 문제인지 궁금합니다...

multiple definition of `EXTI0_IRQHandler'
오류는 이 때문이고요, 중복선언이 되어 있다는 말입니다.
stm32f4xx_it.c 파일 205라인에 선언이 되어있고
main.c 파일 185에도 선언이 있다는 뜻이죠
stm32f4xx_it.c 파일 205라인에 선언 되어있는 인터럽트 함수를 주석처리하고 메인에 추가하든지
메인에 추가하지말고 stm32f4xx_it.c 파일 205라인에 선언된 함수 안에 인터럽트 코드를 작성하면 됩니다.

stm32 작성일감사합니다 주석처리해보고 다시해보겠습니다
