You need to make sure that WiringOP is installed on your Orange PI PC. If not, then you need to install it. To do this, run the following commands:

git clone https://github.com/zhaolei/WiringOP.git -b h3

cd WiringOP
chmod +x ./build
sudo ./build

Install Module##

npm i orange-pi-gpio

Usage

Blink app

const Gpio = require('orange-pi-gpio');

let gpio5 = new Gpio({pin:5, mode: 'out', ready: ()=>{
    let value = 1;

    setInterval(function() {
        process.stdout.write('\x1B[2J\x1B[0f\u001b[0;0H');

        if(value){
            console.log('\x1b[32m%s\x1b[0m', `ON`);
        } else {
            console.log('\x1b[31m%s\x1b[0m', `OFF`);
        }
        
        gpio5.write(value);
        value = +!value;
    }, 50);

}});

Methods

read

const Gpio = require('orange-pi-gpio');

let gpio5 = new Gpio({pin:5});

gpio5.read()
    .then((state)=>{
        console.log(state); //state of pin 5
    });

write

const Gpio = require('orange-pi-gpio');

let gpio5 = new Gpio({pin:5});

gpio5.write(1); // write 1 to pin 5
gpio5.write(0); // write 0 to pin 5
