Every time I try to import the .zip, I recieve the following error: "The library "Adafruit_VS1053_Library cannot be used. Library names must contain only basic letters and numbers. (ASCII only and no spaces, and it cannot start with a number)" Why isn't it working?

Hello everybody!

I'm developing a build in which I need to play an .mp3 file in the ESP32-based Feather HUZZAH32 board.
In order to get that, I decided to use the Adafruit Music Maker FeatherWing (without Amp) board, and Adafruit VS1053 library.

I started with the example recomended in official site. So, after connecting all the pins of both boards, I uploaded the VS1053 library's example "feather_player" without any modification. However, I get the error below:

This text is repeated once and again without any change. The only sound you can hear is the one that is generated at start of the sketch.
You can see that the error doesn't start when reading the uSD card: it appears when starts playing a file. I don't know if it is a library's problem, but I post it just in case.

I have tried checking conections, changing the HUZZAH32 board (I got two of them), changing the uSD card, changing audio files format, making all code and conection changes that appears on the official troubleshooting page... But none of them worked. Even more, none of the characters of the error changed.

Could somenone explain what should I do? Why does the error occur?

Thank you very much for help!

This:
https://github.com/adafruit/Adafruit_BusIO

The pausePlaying function has an issue where the else statement would set playingMusic to true despite the currentTrack has finished if you call pausePlaying with false.
This causes the call to the function stopped to return false despite the fact that the currentTrack has
stopped because playingMusic was flipped to true despite that not being true.

This is my fix. I tried to commit to the git but I don't have the permissions:

void Adafruit_VS1053_FilePlayer::pausePlaying(boolean pause) {
if (pause)
playingMusic = false;
else {
// Added this because
// calling pausePlaying with false would
// caused the call to stopped to return
// false despite the fact that the track
// has indeed stopped playing.
// Could add else{ playingMusic = false; }
// but it seems unnecessary.
if (currentTrack)
{
playingMusic = true;
}
feedBuffer();
}
}

Using the sdfat option with
#define PREFER_SDFAT_LIBRARY 1
causes many compiler errors.
I think it's the same as

The begin recording, !digitalRead should evaluate to true, but not to end recording.

VS1053 Library does not have support for ATmega256RFR2. This is Atmel's processor with LightWeight Mesh (LWM) capability. My Votsh WAVES project uses the RFR2 and the VS1053 library. Discussion on this issues is at https://forums.adafruit.com/viewtopic.php?f=22&t=63182.

Solution is to add RFR2 to Adafruit_VS1053.cpp after line 68:

#elif defined(__AVR_ATmega256RFR2__)

  5, 1,

I'm using a Rev D Music Maker FeatherWing. I noticed this issue when adjusting the volume via a potentiometer, but I was able to reproduce it with just the Feather and FeatherWing by varying the volume as a function of elapsed time. With 1-2 ms of delay inside of loop(), the playback reliably stops somewhat randomly. With higher values of delay, the pausing is less frequent but still reproducible.

An odd detail is that playingMusic still returns true, and if I trigger a pause and then play with pausePlaying(true) and pausePlaying(false), the music picks up where it left off.

Per musicPlayer.sciRead(VS1053_REG_VOLUME), the volume levels are being set correctly on the MusicMaker.

Adafruit_VS1053_Soundbug.zip

Problem Description

I'm currently facing challenges with the Ogg recording example on the breakout board utilizing the VS1053 chip. My recorded files consistently exhibit a recurring issue. Specifically, there are missing words in the recordings.

Steps Taken

Set recording pin to GND.
Speak into the microphone.
Remove the record pin from GND.
Wait for a brief period.
Disconnect the Arduino Nano.
Insert the SD card into the computer to listen to the recording.
Attempted Solutions
I've experimented with various approaches, including:

Trying different SD card libraries.

Adjusting buffer sizes to potentially address the missing words issue.
However, none of these attempts have resolved the problem.

Request for Assistance

I'm reaching out to the community for guidance. Has anyone successfully used this breakout board for recording? If so, were there specific modifications or adjustments made to ensure reliable recording without missing words? Any insights or suggestions would be greatly appreciated.

Thank you for your assistance!

Can I use this lib without Arduino?

I want to use ESP8266 with NodeMCU firmware and the VS1053 breakout board.

When I later build my production system with an VS1053 chip can I use this lib as well?

• Arduino board: WeMos (not really) ESP32 R2, basically generic ESP32
• Arduino IDE version: 1.8.5

The interrupt-based playback does not work on ESP32, calling the SD library from within an interrupt handler seems to cause an almost immediate crash. The exception stack trace is as follows:

I've done a quick test where the interrupt handler sets a flag, letting the main loop know to populate the buffer and that works fine. I'm pretty sure I can set up a solution using a separate task to just feed the buffer as and when with maybe a larger memory buffer to cater for the extra latency. Of course this will be super ESP32 specific and couldn't be integrated back into the library.

Any time I try to compile a sketch that uses both this lib and the Arduio Yun Bridge library, I get a stack of errors (full output below).

I think this is actually an Arduino bug (arduino/Arduino#1942) but I'm hoping that maybe we can put a workaround into this library, at least until the root issue is resolved.

I'm happy to put in some work, but I'm not sure what the best way to handle this is. Do you think something like freetronics/FTOLED@7f4476f is reasonable?

How do you send a string to the library to play of the SD?
I can't find a way to pass a string variable. It would be handy for making playlists using the found MP3 names.
Thanks :)

The VS1053 library does not work with ESP32's.

• Arduino board: Adafruit ESP32-S3 NO_PSRAM
• Adafruit hardware: Breakout https://www.adafruit.com/product/1381
• Arduino IDE version: 2.0.3 & 2.1.0

Steps to reproduce:

• Open the "player_simple.ino" example after installing the library
• Set pins for BREAKOUT_RESET 9, BREAKOUT_CS 10, BREAKOUT_CS 6, CARDCS 4, DREQ 3
• Connect according to the above
• Compile & upload

This will cause a hardware crash on the ESP32, causing it to reboot at a regular interval. Changing from this constructor:

Adafruit_VS1053_FilePlayer(BREAKOUT_RESET, BREAKOUT_CS, BREAKOUT_DCS, DREQ, CARDCS);

... to the software SPI version:

Adafruit_VS1053_FilePlayer(MOSI, MISO, SCK, BREAKOUT_RESET, BREAKOUT_CS, BREAKOUT_DCS, DREQ, CARDCS);

... does stop the crashing, but the device still does not play audio files. Printing out MOSI, MISO and SCK lists the correct pins (35, 37, 36) so it does not make much sense that calling this makes a difference (but it does).

This library contains working code (as a workaround), but I'd at least update the Adafruit guide for the VS1053 products and point out that this library does not work with ESP32 for now..

The Travis Build of this Library seems to be broken due to instructure problems:
Verifying... fork/exec /bin/xtensa-lx106-elf-g++: no such file or directory

(see https://travis-ci.com/adafruit/Adafruit_VS1053_Library/builds/143226000 )

Hi,
I was having glitching problems recording OGG audio with ESP8266 (NodeMCU) due to low SPI clock speed.
I've simply fixed it changing the lines (in Adafruit_VS1053.cpp) from:
#define VS1053_CONTROL_SPI_SETTING SPISettings(250000, MSBFIRST, SPI_MODE0) #define VS1053_DATA_SPI_SETTING SPISettings(8000000, MSBFIRST, SPI_MODE0)
to:
#if defined(ESP8266) #define VS1053_CONTROL_SPI_SETTING SPISettings(1000000, MSBFIRST, SPI_MODE0) #define VS1053_DATA_SPI_SETTING SPISettings(20000000, MSBFIRST, SPI_MODE0) #else #define VS1053_CONTROL_SPI_SETTING SPISettings(250000, MSBFIRST, SPI_MODE0) #define VS1053_DATA_SPI_SETTING SPISettings(8000000, MSBFIRST, SPI_MODE0) #endif
setting speed to 1MHz/20MHz. As I can hear now, no glitches anymore!

• Arduino board: Feather M0 basic proto + Adafruit Music Maker Feather Wing
• Arduino IDE version: 1.8.5
• Problem: The millis function is very inaccurate when playing an audio file. I have a sketch which uses the millis function to blink a led once every 3 seconds, the led is on for only 300 mS. When the library is playing music the 300 mS time goes to 429 mS (that’s almost 150 %). The file is 320 kb/s MPEG Audio Layer ½, dual channel mono, 44100 Hz, 32 bits.

The millis function is also used on my program to keep track of time using Unix time (not only to blink leds), so it´s desirable to keep timings as accurate as possible.

I know this file is high bitrate, but we´re developing a prototype for a third party. It should be able to handle high bitrate files, because the final user might not be able to tell if an MP3 file is 128 or 320 kbps.

The problem seems to be related to how the code handles the DREQ interrupt, as this function takes several milliseconds to execute while the data is transferred from the SD card and then to the VS1053. In the mean time the Systick might not be handled correctly.

Possible solutions that I thought:

• Raise the priority of the interrupt used for millis() so it can nest in the DREQ interrupt (not sure about the side effects of this and if it is even possible because of how NVIC is initialized, involves messing with the Arduino core).
• Not use interrupts at all and handle all the data buffer feeding on the main loop.

Has anybody else experienced this problem, is there a workaround for this?

Thank you in advance.

Would it be possible/sensible to increase the SPI clock settings for, both, access to SD card and VS1053b? The SD card should be good up to 25 Mhz, and the VS1053b should be happy with 5 Mhz (internal clock of 36.864 Mhz / 7, according to the datasheet). I'm having some issues here with high-bitrate files clogging the bus ... Alternatively, this could perhaps be handled with user-defined parameters through an overloaded constructor? Happy to send a PR if you're interested. Cheerio :-)

Arduino Board: MEGA2560
IDE Version: 1.8.5

I've connected the VS1053 and started playing audio.
MP3 files work great, but WAV files produce distortion.

The shield datasheet says it is able to support wav files so I am lead to believe the problem is from this library?

A handful of people using this library have experienced issues reading IR or RFID values when music is playing the background. The forum topic linked below goes into greater detail and a workaround was provided.

The workaround involves pausing the music, delaying for 10ms, reading from IR/RFID then resume playing. The pause-read-unpause happens so quickly that the playback is unaffected. Can a change be made to the library to avoid doing this?

void loop() {
musicPlayer.pausePlaying(true);
delay(10);

if (irrecv.decode(&results)) {
musicPlayer.pausePlaying(false);
Serial.println(results.value, HEX);

   // do something with the result

   irrecv.resume(); // Receive the next value

}

musicPlayer.pausePlaying(false);
return;
}

Hey,
In the FilePlayer constructors the pin on _cardCS is set high, however i cannot see anywhere _cardCS is being set and believe it is supposed to be just the local variable cs instead.
On my board the value of _cardCS is defaulting to 64 on power on and is causing a crash.
Thanks, Mitchell

Value of 8Mhz not supported (no sound) on M0 chip. Reduced to 4Mhz for reliable audio.

I have these memory cards:

Also, I tried different libraries. This and this. Memory cards of 1GB and 256MB do not work on both libraries. At the same time, SdFat initializes these memory cards and works successfully with them, which suggests that the problem is in the VS1053 library itself. Any ideas on how to make everything work?

Code for SdFat version:

#include <SPI.h>
#include <SdFat.h>
#include <vs1053_SdFat.h>

SdFat sd;
vs1053 MP3player;

void setup() {
  Serial.begin(9600);

  sd.begin(SdSpiConfig(9, SPI_HALF_SPEED));

  MP3player.begin();
  MP3player.setVolume(10, 10);
  MP3player.playMP3("001.mp3");
}

void loop() {
  delay(1000);
}

When I compile and upload the player_miditest, it seems to work fine, so I'm a little confused why this one doesn't work.

My player worked fine when I used it for the first time. But now it does not give out any sound.
I tried the player_simple example. here are my observations.(I changed the CS pin of SD card to Pin 34 of Arduino mega).

1)player initializes
2) it lists all files on the SD-card.
3) It stops at playing track-2 for some time (which roughly matches the time of the audio files).

note : It does not seems to be the freeze issue as in #4 as the player does not stop.

The record_ogg.ino example does not seem to support recording more than one .ogg file without hard-resetting the board in between recordings. The first file (RECORD00.ogg) is recorded fine and plays back in Audacity etc., of subsequent recordings only the first 1024 bytes make it to the SD card.

Steps to reproduce:

• Open record_ogg.ino, change the following to the music maker shield pins:

  // define the pins used
  #define RESET -1 // VS1053 reset pin (output)
  #define CS 7 // VS1053 chip select pin (output)
  #define DCS 6 // VS1053 Data/command select pin (output)
  #define CARDCS 4 // Card chip select pin
  #define DREQ 3 // VS1053 Data request, ideally an Interrupt pin

• Load record_ogg.ino to the Uno

• Press the REC_BUTTON to do multiple recordings

• Inspect recordings on PC

If the Arduino is reset in between recordings, this issue does not occur. The plugin datasheet states that the plugin does need to be reloaded between recordings (e.g., Sec 2.3.5, point 6), so maybe the only way around it is to do complete board resets between recordings.

Drawback: It takes around 6 seconds to reload the plugin, which delays the start of subsequent recordings from when the button is pressed.

Hello,

I have a problem with the begin() method.
The problem is that begin() method fail a lot of time before work correctly.
What could be the problem?

Thanks

Simeon

The feedBuffer() method relies on DREQ for determining when it is okay to grab more bytes from the SD card, but according to the datasheet this is not sufficient, as DREQ can change for other reasons besides "ready for data".

In my sketch I noticed that repeatedly calling startPlayingFile() will eventually cause the Arduino to freeze, and when it does the DREQ pin remains low.

Doing a softReset() of the VS1053 prevents the freezing, but that is not ideal.

For this library's void Adafruit_VS1053::setVolume(uint8_t left, uint8_t right) { method - what are the possible range of values? In the sample app you have:

 // Set volume for left, right channels. lower numbers == louder volume!
  musicPlayer.setVolume(10, 10);

but no mention of whether this is a small value (10) or big value.

I'm assuming 0-255, but I can't tell from looking at the sample or any comments in the source.

Is it possible that will be integrated to the lib?

trying to use this with a custom set of spi pins but it dosnt work on an esp32. if i change the board pin definitons for the spi pins then it works.

Using a Pro Micro or Lenoardo (32U4) and Arduino 1.8.3, the player_interrupts.ino example fails to finish track playback using the Interrupt method. After a certain amount of time, DREQ just goes HIGH and stays high, playback stops.
With 1.0.2 or earlier, this does not happen.

When using with Adafruit's sdfat library, you get errors and it will refuse to compile.

In the latest release (downloaded 17 June 2013) I had to add an include guard in the header file to get the library to compile.

Fix:
add:

[

ifndef Adafruit_VS1053_h

define Adafruit_VS1053_h

...

endif /* Adafruit_VS1053_h */

]

to Adafruit_VS1053.h

Hello dear Adafruit

I purchased a Feather Huzzah 32 with a ESP32 on it, and a Adafruit Music Maker FeatherWing - MP3 OGG WAV MIDI Synth Player (PID: 3357).
I used the V1053 library and it didn't work. In fact only the first bytes of the data is played for a fraction of a second.
Looking into the code in the feedBuffer_noLock I noticed that if readyForData() returns 0 everything stops, and it seems that the data is fed too fast. After 110 times of writing 32 bytes, readyForData() returns 0 . The datasheet of the chip explains that when that happens the code should just wait for the buffer to be ready again and continue.

I have tentatively changed the code to this

void Adafruit_VS1053_FilePlayer::feedBuffer_noLock(void) {
  if ((! playingMusic) // paused or stopped
      || (! currentTrack)
      || (! readyForData())) {
    return; // paused or stopped
  }

  int cnt = 0;
  // Feed the hungry buffer! :)
  while (playingMusic/*readyForData()*/) {
    // Read some audio data from the SD card file
    int bytesread = currentTrack.read(mp3buffer, VS1053_DATABUFFERLEN);

    if (bytesread == 0) {
      // must be at the end of the file, wrap it up!
      playingMusic = false;
      currentTrack.close();
      break;
    }

    while(!readyForData()){
      //wait for the buffer to be ready to receive more data
    }
    playData(mp3buffer, bytesread);
  }
}

It keeps reading the data the until playingMusic becomes false.
But it will wait for readyForData() to be 1 before calling playData()

Hopefully it can be an improvement to the library for controllers like ESP32.
I am very new to whole this so if you see a problem in my code or my thinking it's very welcome.

Thanks

By the way Adafruit, you are so awesome !

I was trying to make the differential Output work by loading the current patch for the VS1053 and using the following settings afterwards:

  // Enable Mono Output
  musicPlayer.sciWrite(VS1053_REG_WRAMADDR, 0x1e09);
  musicPlayer.sciWrite(VS1053_REG_WRAM, 0x0001);

  // Enable differential output
  uint16_t mode = VS1053_MODE_SM_DIFF | VS1053_MODE_SM_SDINEW;
  musicPlayer.sciWrite(VS1053_REG_MODE, mode);

Unfortunately this didn't work and took me quite a while to realize that startPlayingFile is doing

  // reset playback
  sciWrite(VS1053_REG_MODE, VS1053_MODE_SM_LINE1 | VS1053_MODE_SM_SDINEW);

Is there a reason for this? IMHO startPlayingFile shouldn't mess with the MODE register.
