@maukoell said in Music Player Module:
Hello,
I am trying to create a module which plays music from a directory. I wanted to use two buttons to control it. One for Pause/Play and one to skip the current song. But unfortunately when I start the MM2 I always get the message that it is not able to find the helper for my module. I’m new to node.js so maybe there are just some basic mistakes.My module:
Module.register("MMM-MusicPlayer",{ defaults: { playButtonPIN: 10, nextButtonPIN: 12, clickDelay: 500, musicPath = "/home/pi/MagicMirror/modules/MMM-MusicPlayer/music", }, start: function() { this.sendSocketNotification("BUTTON_CONFIG", this.config); Log.info('Starting module: ' + this.name); } });My node_helper:
"use strict"; const NodeHelper = require("node_helper"); const gpio = require("onoff"); var path = require('path'); var fs = require('fs'); const { Howl, Howler } = require('howler'); var sound; var musicList = []; var index = 0; var started; var config; module.exports = NodeHelper.create({ start: function () { started = false; }, // Subclass socketNotificationReceived received. socketNotificationReceived: function (notification, payload) { const self = this; if (notification === 'BUTTON_CONFIG' && started === false) { config = payload; self.fromDir(config.musicPath, "mp3"); self.createSound(); var GPIO = require('onoff').Gpio; var button1 = new GPIO(config.playButtonPIN, 'in', 'both', { persistentWatch: true, debounceTimeout: config.clickDelay }); button1.watch(function (err, state) { // 1 == pressed, 0 == not pressed if (state === 1) { if (sound.playing()) { sound.pause(); } else { sound.play(); } } }); var button2 = new GPIO(config.playButtonPIN, 'in', 'both', { persistentWatch: true, debounceTimeout: config.clickDelay }); button2.watch(function (err, state) { // 1 == pressed, 0 == not pressed if (state === 1) { self.playNext(); } }); started = true; } }, fromDir: function(startPath, filter) { if (!fs.existsSync(startPath)) { Log.info("no dir ", startPath); return; } var files = fs.readdirSync(startPath); var i; var fullPath; var filename; var stat; for (i = 0; i < files.length; i+=1) { fullPath = path.join(startPath, files[i]); filename = files[i]; stat = fs.lstatSync(fullPath); if (stat.isFile()) { if (filename.indexOf(filter) >= 0) { musicList.push(fullPath); } } } }, playNext: function() { if (sound.playing()) { sound.stop(); } index += 1; if (index === musicList.length()) { index = 0; } sound.play(index); }, createSound: function() { sound = new Howl({ src: musicList }); } } );Maybe someone can help me.
Thanks in advance
I don’t think that your code respects helpers as described in official documentarion,
Or we are not talking about the same helpers Pnr Status.TextNow
