fnd 3개에 main에서 키보드를 누르면
그 순서에 따라 data를 표시합니다.전송중 에러가 발생하면 체크섬을 하고
이상없이 수신시 data로 인정합니다.
이 프로그램은 확실히 제가 시험하였고
체크섬 때문에 고생 좀 했습니다.
-메인에서 키를 누르면 그 키를 시리얼로 전송하여
리모트 cpu에 날라감니다
예를 면
1key를 누르면 리모트에서는 001
12key를 누르면 리모트에서는 012
123key를 누르면 리모트에서는 123
다음으로 1234key를 누르면
004로 표시됩니다
따라서 3개 버턴을 누르면 다음4번째 부터는
리셋이 되게 되는거지요
직접 사용해보세요.
포트에 따라
===main 측=======
4*4 key를 설치하시고
max232c ic를 tx,rx단자에 결선합니다.
====리모트 측====
fnd3개설치 하시고(scan방식)
fnd3개에 Common단자에는 a1270 tr을 각1개식
달아 줌
다음으로 FND(1056) a`f까지 핀에는(data라인)저항을 47오옴을
결선합니다
-max232c ic를 tx,rx단자에 결선합니다.
아주 간단하죠
참고로max232c를 사용치 않을때에는
tx,rx단자에 반드시 풀다운4.7k를 걸어 주세요
감사합니다.

안녕하세요? 연세대학교 전기랑 01학번 조지현입니당~!
이번에 Hand Motion Capture Device를 만들면서 AVR을 공부했습니다.
요기 강좌에 없길래.. 제가 한번 주제넘게 올려봅니다~
저는 gcc를 사용했으며.. Datasheet와 gccdemo7이라는 예제를 참고 했습니다(하다보니 예제와 너무 똑같이 되었군요..--)
먼저 하드웨어 부분은..
MAX어쩌구 칩으로 시리얼 케이블과 연결하구..
캐패시터 붙이구 ....
줄 4개 뽑아서... 하나는 VCC하나는 GND
둘은 RXD와 TXD에 연결하면 되죠..
(제가 만든적은 없으니.. 알아서들 만드세요)
저는 MTerm에서 테스트 했습니다..*/
