@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
