Arduino Uno + VS1053 Sparkfun MP3- Error #6

Post by halloweenrick » Wed 2018-11-14 3:09

Hi I am trying to use the File Player code from Bill Porter's website :http://www.billporter.info/2012/01/28/s ... o-library/ and I keep getting error #6: "Error code: 6 when trying to start MP3 player Warning: patch file not found, skipping. If I try to play track001.mp3 anyway, then I get Error#2 File not found. As I've gone through different Arduino sites, this error occurs, but no one seems to have found a solution, or if they have they are not sharing it very well. The odd thing is I can get it to play the sine code (press T) but nothing else works.
Here is the File Player code:

Code: Select all

/**
 * \file FilePlayer.ino
 *
 * \brief Example sketch of using the MP3Shield Arduino driver, with flexible list of files and formats
 * \remarks comments are implemented with Doxygen Markdown format
 *
 * \author Bill Porter
 * \author Michael P. Flaga
 *
 * This sketch listens for commands from a serial terminal (such as the Serial
 * Monitor in the Arduino IDE). Listening for either a single character menu
 * commands or an numeric strings of an index. Pointing to a music file, found
 * in the root of the SdCard, to be played. A list of index's and corresponding
 * files in the root can be listed out using the 'l' (little L) command.
 *
 * This sketch allows the various file formats to be played: mp3, aac, wma, wav,
 * fla & mid.
 *
 * This sketch behaves nearly identical to MP3Shield_Library_Demo.ino, but has
 * extra complicated loop() as to recieve string of characters to create the
 * file index. As the Serial Monitor is typically default with no CR or LF, this
 * sketch uses intercharacter time out as to determine when a full string has
 * has been entered to be processed.

I would love to use the simpler code found on his website, but I cannot get it to verify and upload:

Code: Select all

#include <SPI.h>
#include <SdFat.h>
#include <SdFatUtil.h> 
#include <SFEMP3Shield.h>

SdFat sd;
SFEMP3Shield MP3player;

void setup() {

  Serial.begin(9600);

  //start the shield
  sd.begin(SD_SEL, SPI_HALF_SPEED);
  MP3player.begin();

  //start playing track 1
  MP3player.playTrack(1);
}

//do something else now
void loop() {

  Serial.println("I'm bored!");
  delay(2000);

}
What am I doing wrong? I have verified that my Mp3 files are in the root of the sd card, and I downloaded the recent patch onto the sd card as well.
I am trying to just play one sound file for a halloween startle prop I'm building. Thanks for any help you can provide.

Re: Arduino Uno + VS1053 Sparkfun MP3- Error #6

Sounds like the Arduino code doesn't handle your card - the obvious potential reasons:
- It's formatted as something else than FAT
- The FAT partition is inside an EFI partition and the code doesn't support it.
But then the SdFat init should probably return an error, so ... maybe adding debug information there would reveal more.

Have you tried different cards?

SOLVED! Thank you for the debug hint. When I went in and debugged, I saw this:

track001.mp3.mp3

So although I was following the 8.3 format for file names, the card was adding ANOTHER .mp3 file extension on. So I simply renamed the file "track001" with no .mp3 file extension, and now it works perfectly.

Thank you Pasi!
