Tinker Board S : pi4j

Tinker Board의 pwm 제어 하는 예제는 python을 제외하고는 c언어나 java 예제를 찾을 수 없어서 wiringPi 라이브러리를 직접 컴파일 해보았지만 모터의 떨림도 심하고, 발열도 심해서 아직은 불안한것 같습니다. python의 pwm관련 소스를 wiringPi에 추가하고 다시 pi4j 라이브러리에 적용했습니다. pi4j라이브러리와 pi4j를 이용한 Servo.java 예제도 첨부했습니다.동영상을 보시면 알겠지만, 떨림도, 발열도 발생하지 않았습니다.

OS 이미지 SD메모리에 복사

SD 메모리로 부팅

제가 구입한 Tinker Board S의 경우 eMMC에 안드로이드 OS가 설치되어 있어 리눅스 OS 이미지가 복사된 SD 메모리를 삽입하고, 부팅해도 안드로이드로 부팅이 되는데, 아래 이미지 처럼 Maskrom mode로 설정후 부팅하면 SD메모리에 설치된 OS로 부팅이 됩니다.
