#  eStreamPlayer32

An web-based esp32 program to play webradio and mp3/aac files from a lamp or llmp server.

-  Control eStreamPlayer with your phone, pc or tablet.
-  Play your local files.
-  Play preset radio stations.
-  Add new urls and save them to favorites.

Sound output comes from an i2s dac. Currently generic i2s dacs (with `BCK`, `WS` and `DOUT` pins), M5Stack Node and AI Thinker A1S AudioKit are supported.

When flashed to an M5Stack with the Node base you can see some information on the display.

###  Limitations

-  The audioI2S library uses a lot of RAM. eStreamPlayer will only function properly on a board with PSRAM.

- eStreamPlayer is written for playback over http. The esp32 does not speak NFS or SMB which are common ways to share files over a network.
 Instead eStreamPlayer uses a php script on the server to navigate the music folders. 
 Copy this script to the server to use your music library.
 **This is totally insecure and should only be used on a LAN!**

But if you don't have a local music server you can still use eStreamPlayer to tune in to web radio stations and add your own radio stations to presets and favorites.

### Setup

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

1. Download the [latest eStreamPlayer release](https://github.com/CelliesProjects/eStreamPlayer32/releases/latest).
2. Install the [required libraries](#software-needed) and the drivers for your dac. See [supported hardware](#supported-hardware).
3. Copy the php script to your music folder on the server.
4. Open the Arduino IDE.
5. Select Tools->Partition Scheme->No OTA(2MB APP/2MB FATFS).
 If your board does not have that option you can select ESP32 Dev Module in Tools->Board.
6. Open `system_setup.h` and set your wifi credentials and set `SCRIPT_URL` to the php script location.
7. Flash the sketch to your esp32. Set `Tools->Core Debug Level->Info` before you flash so you can grab the ip address from the serial port.
8. On first boot or after a flash erase the fatfs has to be formatted. This will take a couple of seconds.
 Flashing an update will not erase the fatfs data.
 **Note:** Take care to select the same partition table when updating otherwise the partition will be formatted.
 You can monitor the boot progress on the serial port.
9. Browse to the ip address shown on the serial port.

### Supported hardware

Select a board or dac by uncommenting the relevant line in `system_setup.h`.

- Generic i2s dac - Select `GENERIC_I2S_DAC` as board. For dacs that only need `BCK`, `WS` and `DOUT` and no driver setup. Default pins are `BCK` = 21, `WS` = 26, `DOUT` = 22.
- M5 Stack Node - Select `M5STACK_NODE` to compile for M5Stack Node with `MCLK` on `GPIO0`. You need the [wm8978-esp32](https://github.com/CelliesProjects/wm8978-esp32) library for this dac.
- A1S Audio Kit - Select `A1S_AUDIO_KIT` to compile for ESP32-A1S Audio Kit. You need the [AC101](https://github.com/Yveaux/AC101) library for this dac.

### Software needed

- [ESP32-audioI2S](https://github.com/schreibfaul1/ESP32-audioI2S) (GNU General Public License v3.0)
- [AsyncTCP](https://github.com/me-no-dev/AsyncTCP) (LGPL-3.0 License)
- [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer) (LGPL-3.0 License)
- A [lamp](https://en.wikipedia.org/wiki/LAMP_%28software_bundle%29) or llmp webstack to serve local files.
 Apache2 and lighttpd were tested and should work. The php script should be fairly version agnostic.
 Note: Mp3 and aac files should have the `Content-Type: audio/mpeg` http headers set or the decoder will not recognise the files.
