Hello
I am having hard time trying to find nodejs samples with the groovepi and pi 3.
I want to do a simple hello world, I found a groovepi sample with intel edison but obviously that didnt work.
Doing a little of research, I found johny five library but that its only for arduino, but they are supposed to have plugins for other boards, like raspberry, so installed rasp-io, johnny five and tried to run this sample
var raspi = require(‘raspi-io’);
var five = require(‘johnny-five’);
var board = new five.Board({
io: new raspi()
});
board.on(‘ready’, function() {
var lcd = new five.LCD({
controller: “JHD1313M1”
});
lcd.bgColor(r, g, b).cursor(0, 0).print(f);
});
I get this error:
