이 프로그램은 제가 짠건데여~`외부클럭이 들어와서 처음에 10개의 카운트 마다
sega[10]의 한 바이트 씩 target[]의 버퍼에 이동 후 100번 카운트 되면 포트에 sega[0]을 출력하고 그다음 부터는 카운트 10개마다 sega[1]2...3...4이렇게 출력하는 프로그램 입니다. 이렇게 할려고하는데 프로그램이 너무 길어져서 이부분을 어떻게 할지..그리고 포트의 출력 타임시간을 10ms로 유지 후 off하고 싶은데 딜레이 함수로 사용하다 보니까 정확히 맞추기가 어렵습니다. 이부분을 타이머로 on시간을 주는 방법은? 몸도 안좋으신데 어려운건만 물어봐서 죄송합니다.
그럼 몸 건강하시고 메일 주세여^^
