Orange PI Zero GPIO 설치

출처 : WiringOP for Orange pi zero - Beginners - OrangePi - Powered by

현재 pi4j는 Orange PI PC2 지원하지 않아 수정한 jar를 배포합니다.

pi4j-core.jar

$ sudo apt-get install build-essential
$ git clone https://github.com/zhaolei/WiringOP.git -b h3
$ cd WiringOP
$ chmod +x ./build
$ sudo ./build
$ gpio -v
