BPI-M2 ZERO - WiringOP 연동 node.js

출처 : github - bluexmas/node-wiring-bpi-zero

BPI-M2 ZERO에서 node.js용 gpio제어 가능한 패키지가 없어서 직접 제작해보았습니다.

node-wiring-bpi-zero 설치

$ cd ~
$ git clone https://github.com/bluexmas/node-wiring-bpi-zero.git
$ npm install node-wiring-bpi-zero

gpio 확인

$ gpio readall

blink 소스

var wpi = require('wiring-bpi-zero');

wpi.setup();

var pin = 25;

wpi.pinMode(pin, wpi.OUTPUT);

var value = 1;

setInterval(function() {
  wpi.digitalWrite(pin, value);
  value = +!value;
}, 500);

데모 실행

$ sudo node node-wiring-bpi-zero/examples/blink.js
