저번에 "한 번에 2개 이상의 스테핑 모터를 제어하기"를 했었는데.......
'Stepper'라이브러리가 업데이트 많이 됐군요. ㅎㅎㅎ
버전에 맞춰 업데이트해보았습니다.
이전 글에서 'Stepper.h'는 '.step()'이 동작하는 동안 다른 동작을 할 수 없다고 이야기했습니다.
(참고 : [Arduino] 'Stepper.h'는 두개의 모터를 제어할 수 없다. )
그래서 'Stepper.h'를 수정한 라이브러를 작성하고 사용하는 방법에 대한 포스팅입니다.
기존 'Stepper'를 수정하는 방법은 이전 글에서 다뤘으므로 이 포스팅은 수정된 코드만 나열합니다.
1. Stepper.h -> StepperMulti5.h
헤더는 거의 그대로입니다.

2. Stepper.cpp -> StepperMulti5.cpp
약간 바뀐 것이 있는데.....크진 않습니다.
step_number
를
this->step_number
로 바꿔줍니다.

감사합니다. 좋은 날 되세요!!
zip파일로도 부탁드립니다!!
네~ 추가 하였습니다.
안녕하세요 당근천국님 혹시 스텝모터 핀 4개 무엇을 결선 하였는지 알려주실수 있을까요? Nema17 a4988은 dir step pin만 넣으면 되는데 소스에서 4개의 pin이 입력된게 무엇이 입력됬는지 알수가 없네요
결선은 이 포스팅 기준입니다.
https://blog.danggun.net/1810
제가 연결한건 크게 의미가 없는것이 이 라이브러리는 아두이노 표준 라이브러리인 'Stepper'를 수정해서 만들어진 라이브러리입니다.
'Stepper'를 사용할 수 없는 모터드라이버는 사용할 수 없습니다.
