원래크기로보기

tiny10으로 pwm2ppm 컨버터를 만들었습니다.
2ch도 충분히 할 수 있고 코드도 있지만 테스트를 안해봐서 1ch짜리를 올립니다.
이것도 상당히 더 편리하고 좋게 다듬을 수 있는데 구찬으니까 구냥 쓸랍니다.

tiny13을 쓴게 공개되어 있지만 변속기에 기생하기에는 크기가 좀 큽니다.
이거는 변속기에 작은 공간이라도 비집고 들어가서 기성부품처럼 자리잡을 수 있습니다.
사용하지 않는 2핀은 hi 임피던스로 처리해서 전원단자와 쇼트시켜도 무방하게해서 부착을 쉽게 했습니다.

참, 사진에 있는 t10은 전시용이고 실제는 뒤집어서 납땝되어 있습니다. 2012-04-29

이시간에 잠 들지않은 2인입니다.
이작품을 처음보시는 분은 이 것의 목적을 궁금해 하실것 같은데요. 부연설명도
부탁합니다.		 2012-04-29

PWM 2 PPM이라면 적외선 수신기에서나오는 PWM파형을 일반 변속기에 쓸수있도록 PPM으로 바꾸어준다 라는것 인가요?
작은 부품하나 추가로 적외선 수신기에서 브러쉬리스도 쓸수있겠네요 ㅎㅎ		 2012-04-29

어느 hex파일을 쓰는건가요? 고이찌사이트에도 같은 것이 있어 전에 만들어 보았는데 잘 작동하더군요. PIC10F200 을 씁니다. 2012-04-29

다리 4개중에 2개를 선택해서 하나는 입,하나는 출력으로 쓰는거죠. 그러니까 4C2 * 2 = 12가지가 있어요.
끝에있는 숫자 32 라면 B3을 입력 B2를 출력으로 쓰는 코드입니다.
끝에있는 숫자 01 이라면 B0을 입력 B1를 출력으로 쓰는 코드입니다.		 2012-04-29

브러시용 헬기나 기체를 브러시리스화 하실 목적인 것 같습니다. 상용기판에서 나오는 브러시모터용 pwm 신호를 ppm 신호로 변환하면 브러시리스 모터를 사용할 수 있습니다. 2012-04-30
