ESP32 MP3 SD Player Errors

Projects Programming
1

I am at my wits’ end. I was trying to do a simple project having the ESP32 Wroom play a MP3 file from a MicroSD card and playing it through a small speaker with the MAX98357A. I keep getting these errors that I don’t know how to fix.

Here’s my code

/*
  ESP32 SD I2S Music Player
  esp32-i2s-sd-player.ino
  Plays MP3 file from microSD card
  Uses MAX98357 I2S Amplifier Module
  Uses ESP32-audioI2S Library - https://github.com/schreibfaul1/ESP32-audioI2S

Audio audio;
 
void setup() {
    
    // Set microSD Card CS as OUTPUT and set HIGH
    pinMode(SD_CS, OUTPUT);      
    digitalWrite(SD_CS, HIGH); 
    
    // Initialize SPI bus for microSD Card
    SPI.begin(SPI_SCK, SPI_MISO, SPI_MOSI);
    
    // Start Serial Port
    Serial.begin(115200);
    
    // Start microSD Card
    if(!SD.begin(SD_CS))
    {
      Serial.println("Error accessing microSD card!");
      while(true); 
    }
    
    // Setup I2S 
    audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT);
    
    // Set Volume
    audio.setVolume(5);
    
    // Open music file
    audio.connecttoFS(SD,"/AnniversaryAlbum.mp3");
    
}
 
void loop()
{
    audio.loop();    
}

And here are the errors

Any help would be appreciated

Since you did not show us the entire verbose error log, I suspect a library/board mismatch. In other words, you are using a board that the library is not designed for However looking at the snall amount of info I don;t see anything obvious. Since this is one of Bill's (DBWS) sketches, aybe c heck at his YT/Blog/Forum.

You are using a 3.x ESP32 core platform.

You have a manually installed SPI library for the 2.x ESP32 core platform in your libraries subdirectory.

The IDE is seeing that rather than the SPI library in the 3.x ESP32 core platform.

Besides there being many breaking changes between the 2.x and 3.x ESP32 cores platforms, it is never ever a good idea to manually add a library that obscures the core platform specific libaries like Wire, SPI, SoftwareSerial and the like. They are specific to the core platform they are bundled with.

The solution to the problem you have created for yourself should be obvious.
