How to operate wav files without renaming it on card module

Projects Programming
1

As the topic headline explains

All the time we need to rename a wave file for any song in manner like:-

001
002
003
. . .

to get read by SD Card module

But why always this one needed ?

Is there anything we can do a bit little ???

Like, I want to have the system in which I ll copy the files with original name but with required parameters like bit rate etc etc things

&

The coding system will read it or take it as 001 002 like that so I don't have to rename files and don't have to make a note of 70 80 songs that which number is for which wav file when I use to do research work on SD Module

Any possibility to define that way ???

If your files has names, compatible with 8.3 notation (8 chars filename and 3 chars extension), without spaces and non-printing or national characters - you shouldn't rename it.

3

and if it is 4 characters filename and 3 characters extention ?

4

8.3 is the maximum so 4.3 will be OK, but no spaces are allowed in the filename

5

ok le me try this right now

6

It is OK if all chars are digits or letters

7

ok checking

8

All experiments failed

Its not accepting a single letter of english alphabet

9

No change same issue

10

No rule worked not a single thing

11

What is a issue?

12

13

If you expect a help, please show the code

Nothing spcl

All collected from this forum only

#include <SD.h>
#include <SPI.h>
#include <TMRpcm.h>
TMRpcm tmrpcm;
#define SD_ChipSelectPin 53;

void setup() 
{
  
  Serial.begin(9600);
  
  tmrpcm.speakerPin = (46);
  if (!SD.begin(SD_ChipSelectPin))
  {
    Serial.println("SD fail");
    return;
  }

  else
  {   
    Serial.println("SD ok");   
  }
}

void loop() 
{
   tmrpcm.play("001.wav");
   //tmrpcm.play("rare.wav");
}
15

And where are your custom filenames? You said that you want to avoid digit-like names?

16

Change the loop as

void loop() 
{
  
  if (SD.exists("001.wav")==true)  tmrpcm.play("001.wav");
  else Serial.println("File not found");
}

and show the output

I use this MP3 Player / CODEC Based on VS1053 from Adafruit.

The library supports alpha-numeric file names. It works well. I've modified it to support digital I2S audio out of the CODEC. Here's a demo.

Its there at end you can see
rare song of selina I added

//tmrpcm.play("rare.wav");
19

Ok sure le me go thru

If you added file with name "rare.wav", why do you try to play "001.wav" in the code?????
