Arduino Music Player and Memory Issues

bcf7023 · November 6, 2024, 4:51pm

I'm making a music player designed to play from a set of songs I hand-arranged to be played through the Piezo.

Problem is, even just three full-length songs caused me to run up on memory problems. Initially, the sketch itself was using too much memory due to calling playNote() and rest() hundreds of times for each song. I thought I could solve the problem by converting the songs into arrays, but that just went far over the allotted memory for global variables.

Is there any way for me to make the current model feasible without removing songs or reducing their length? Like, say, putting the songs in an external file, then loading them into the main sketch?

Here's the code:

#include <LiquidCrystal.h>
const int upPin = 10;
const int downPin = 9;
const int playPin = 8;
const int piezoPin = 7;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

int upState;
int downState;
int playState;
int prevUpState = 0;
int prevDownState = 0;
int prevPlayState = 0;

You could store the note data on an SD card and read it in as needed. The internet has hundreds of examples of how.

bcf7023 · November 6, 2024, 5:01pm

Perhaps.

van_der_decken · November 6, 2024, 5:06pm

You neglected to say what board you're compiling for. That matters a great deal. If it's an Uno R3, or some other board using a 328P, you might look into using PROGMEM to reduce your RAM usage.

But ignoring that for moment, your sketch wouldn't work even if you had unlimited memory. You are passing array addresses to playSong without passing the length of the arrays. sizeof in playSong doesn't do what you seem to think it will. It'll just give you the size of the pointer that's passed, not the number of elements in the original array. You need to brush up on your basic C programming.

bcf7023 · November 6, 2024, 5:59pm

I'm using an Arduino Uno.
Arrays in Arduino language don't seem to have any length property, and I couldn't find any information on how to pull the length of an array from said array. Is there such a property? Or do I just need to hard-code it?

Delta_G · November 6, 2024, 6:18pm

You can use

sizeof(array) / sizeof(array[0])

To get the number of elementsnin an array but you can't do that in your function because it on nly has a pointer to the array and sizeof will just give you the size of the pointer. You have to figure the size of that array someplace where it is in scope.

van_der_decken · November 6, 2024, 6:41pm

Here's a good explanation of how to determine the number of elements in an array in C:

And here's an important "why it doesn't work when an array is passed to a function" provisio and why you have to pass the length as a parameter as well:

bcf7023 · November 6, 2024, 7:22pm

Thank you.

Terrypin · November 8, 2024, 3:23pm

Any special reason, academic curiosity apart, why you want to play music through a piezo transducer? Seems an obvious project for the DFRobot DFR MP3 Player?

bcf7023 · November 8, 2024, 3:47pm

I just felt like it. Plus, your comment is the first I'm hearing about the DFRobot DFR MP3 Player.

Terrypin · November 8, 2024, 5:21pm

As you're posting in Project Guidance I assumed you might be looking for suggestions about your 'Arduino Music Player' project.

If that's so I recommend a search using 'arduino music player' either here in the forum or within the 23 pages of hits delivered by Google Search.

If not, and your interest is solely about your coding/memory problem, I suggest you ask a moderator to move the thread to Programming Questions.

bcf7023 · November 8, 2024, 8:43pm

I'm going to start a new thread there momentarily; I actually got a major lead for the memory problem yesterday, but I ran up on some new issues.
