# ESP32_VS1053_Stream



[![Codacy Badge](https://api.codacy.com/project/badge/Grade/7571166c872e4dc8a899382389b73f8e)](https://app.codacy.com/gh/CelliesProjects/ESP32_VS1053_Stream?utm_source=github.com&utm_medium=referral&utm_content=CelliesProjects/ESP32_VS1053_Stream&utm_campaign=Badge_Grade_Settings)



A streaming library for esp32, esp32-wrover, esp32-s2 and esp32-s3 with a separate VS1053 codec chip.


This library plays mp3, ogg, aac, aac+ and flac files and streams and uses [ESP_VS1053_Library](https://github.com/baldram/ESP_VS1053_Library) to communicate with the decoder.



This library plays http, https (insecure mode) and chunked audio files and streams.

Also plays mp3 and ogg files from sdcard.



Visit [eStreamPlayer32_VS1053 for PIO](https://github.com/CelliesProjects/eStreamplayer32-vs1053-pio) to see a [PlatformIO](https://platformio.org/platformio) project using this library.



## How to install and use



Install [ESP_VS1053_Library](https://github.com/baldram/ESP_VS1053_Library) and this library in your Arduino library folder.



Take care to install the master branch of the VS1053 library or at least a version from commit [ba1803f](https://github.com/baldram/ESP_VS1053_Library/commit/ba1803f75722a36f3e9f539129e885bea3c60f71) or later because the `getChipVersion()` call that is needed is not included in the latest release.
See https://github.com/CelliesProjects/ESP32_VS1053_Stream/issues/23



Use the [latest Arduino ESP32 core version](https://github.com/espressif/arduino-esp32/releases/latest).



## Example: play a stream

```c++

#include 

#include 

#include 

#include                // https://github.com/baldram/ESP_VS1053_Library

#include 



#define SPI_CLK_PIN 18

#define SPI_MISO_PIN 19

#define SPI_MOSI_PIN 23



#define VS1053_CS 5

#define VS1053_DREQ 22



ESP32_VS1053_Stream stream;



const char* SSID = "xxx";

const char* PSK = "xxx";



void setup() {

    Serial.begin(115200);

    Serial.println("\n\nVS1053 Radio Streaming Example\n");



    // Connect to Wi-Fi

    Serial.printf("Connecting to WiFi network: %s\n", SSID);

    WiFi.begin(SSID, PSK);  

    WiFi.setSleep(false);  // Important to disable sleep to ensure stable connection

## Example: play from SD card

```c++

#include 

#include 

#include                // https://github.com/baldram/ESP_VS1053_Library

#include 



#define SPI_CLK_PIN 18

#define SPI_MOSI_PIN 23



#define VS1053_CS 5

#define VS1053_DCS 21

#define VS1053_DREQ 22

#define SDREADER_CS 26



ESP32_VS1053_Stream stream;



bool mountSDcard() {

    if (!SD.begin(SDREADER_CS)) {

        Serial.println("Card mount failed"); 

        return false;

    }



    uint8_t cardType = SD.cardType();

    if (cardType == CARD_NONE) {

        Serial.println("No SD card attached");

        return false;

    }



    uint64_t cardSize = SD.cardSize() / (1024 * 1024);

    Serial.printf("SD Card Size: %lluMB\n", cardSize);

    return true;

}



void setup() {

    Serial.begin(115200);

    Serial.println("\n\nVS1053 SD Card Playback Example\n");



    // Start SPI bus

    SPI.setHwCs(true);

    SPI.begin(SPI_CLK_PIN, SPI_MISO_PIN, SPI_MOSI_PIN);



    // Mount SD card

    if (!mountSDcard()) {

        Serial.println("SD card not mounted - system halted");

        while (1) delay(100);

    }



    // Initialize the VS1053 decoder

    if (!stream.startDecoder(VS1053_CS, VS1053_DCS, VS1053_DREQ) || !stream.isChipConnected()) {

        Serial.println("Decoder not running - system halted");

        while (1) delay(100);

    }



    Serial.println("VS1053 running - starting SD playback");



    // Start playback from an SD file

    stream.connecttofile(SD, "/test.mp3");



    if (!stream.isRunning()) {

        Serial.println("No file running - system halted");

        while (1) delay(100);

    }



    Serial.print("Codec: ");

    Serial.println(stream.currentCodec());



    Serial.print("Bitrate: ");

    Serial.print(stream.bitrate());

    Serial.println(" kbps");

}



void loop() {

    stream.loop();

    delay(5);

}



void audio_eof_stream(const char* info) {

    Serial.printf("End of file: %s\n", info);

}

```



## Known issues

Ogg files can not be started with an offset without first playing a couple of seconds from the start of the file. 



## Tips for troublefree streaming



### WiFi setup



Do not forget to switch WiFi out of power save mode:



```c++

...

WiFi.begin(SSID, PSK);

WiFi.setSleep(false); 

...

```



### Prevent reboots while playing

Early version of the esp32 have issues with the external psram cache, resulting in reboots.
Workarounds are possible depending on the hardware revision.



#### Revision V0.0

No workarounds are possible for this revision other than not using the psram.



#### Revision V1.0

On revision V1.0 psram can be used with the following build flags:

```bash

-D BOARD_HAS_PSRAM

-mfix-esp32-psram-cache-issue

-mfix-esp32-psram-cache-strategy=memw

```



#### Revision V3.0

On revision V3.0 psram can be used with the following build flag:

```bash

-D BOARD_HAS_PSRAM

```



Source: [esp-idf api guide on external ram](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/external-ram.html#chip-revisions).



#### Find your hardware revision



In PIO you can find out what hardware revision you have by running `esptool.py flash_id` in a terminal.



In Arduino IDE go to `File->Preferences` and find the `Show verbose output during` option. Check the box marked `upload`.
You can now see the hardware revision when you upload a sketch.



# Functions

### Initialize the VS1053 codec



```c++

bool startDecoder(CS, DCS, DREQ)

```

### Check if VS1053 is responding

```c++

bool isChipConnected()

```

### Start or resume a stream



```c++

bool connecttohost(url)

```

```c++

bool connecttohost(url, offset)

```

```c++

bool connecttohost(url, user, pwd)

```

```c++

bool connecttohost(url, user, pwd, offset)

```

### Start or resume a local file

```c++

bool connecttofile(filesystem, filename)

```

```c++

bool connecttofile(filesystem, filename, offset)

```

### Stop a running stream

```c++

void stopSong()

```

### Feed the decoder

```c++

void loop()

```

This function has to called every couple of ms to feed the decoder with data.
For bitrates up to 320kbps somewhere between 5-25 ms is about right.

### Check if stream is running

```c++

bool isRunning()

```

### Get the current volume

```c++

uint8_t getVolume()

```

### Set the volume

```c++

void setVolume(uint8_t volume)

```

Value should be between 0-100.

### Set bass and treble

```c++

uint8_t rtone[4]  = {toneha, tonehf, tonela, tonelf};

void setTone(rtone)

```

Values for `rtone`:

```c++

toneha       = <0..15>        // Setting treble gain (0 off, 1.5dB steps)

tonehf       = <0..15>        // Setting treble frequency lower limit x 1000 Hz

tonela       = <0..15>        // Setting bass gain (0 = off, 1dB steps)

tonelf       = <0..15>        // Setting bass frequency lower limit x 10 Hz

```

### Get the current used codec

```c++

const char* currentCodec()

```

Returns `STOPPED` if no stream is running.

### Get the current stream url

```c++

const char* lastUrl()

```

The current stream url might differ from the request url if the request url points to a playlist.

### Get the filesize

```c++

size_t size()

```

Returns `0` if the stream is a radio stream.

### Get the current position in the file

```c++

size_t position()

```

Returns `0` if the stream is a radio stream.

### Get the buffer fill status

```c++

const char *bufferStatus()

```

Returns `0/0` if there is no buffer.
Otherwise returns something like `4096/65536` which means 4kB waiting in a 64kB buffer.

```c++

void bufferStatus(size_t &used, size_t &capacity)

```

This version takes two `size_t` variables by reference.
Works the same as the `const char *` version.



NOTE: A buffer will only be allocated if there is enough free psram.



# Event callbacks



### Station name callback.



```c++

void audio_showstation(const char* info)

```

### Stream information callback.



```c++

void audio_showstreamtitle(const char* info)

```

### End of file callback.



```c++

void audio_eof_stream(const char* info)

```

Returns the eof url or path.
Also called if a stream or file times out/errors.



You can use this function for coding a playlist.
Use `connecttohost()` or `connecttofile()` inside this function to start the next item.
