Squeezelite-esp32

Supported Hardware

SqueezeAMP

Works with the SqueezeAMP see here and here. Add repository https://raw.githubusercontent.com/sle118/squeezelite-esp32/master/plugin/repo.xml to LMS if you want to have a display

Use the squeezelite-esp32-SqueezeAmp-sdkconfig.defaults configuration file.

ESP32-WROVER + I2S DAC

Squeezelite-esp32 requires esp32 chipset and 4MB PSRAM. ESP32-WROVER meets these requirements.
To get an audio output an I2S DAC can be used. Cheap PCM5102 I2S DACs work others may also work. PCM5012 DACs can be hooked up via:

I2S - WROVER
VCC - 3.3V
3.3V - 3.3V
GND - GND
FLT - GND
DMP - GND
SCL - GND
BCK - 26
DIN - 22
LCK - 25
FMT - GND
XMT - 3.3V

Use the squeezelite-esp32-I2S-4MFlash-sdkconfig.defaults configuration file.

Configuration

To access NVS, in the webUI, go to credits and select "shows nvs editor". Go into the NVS editor tab to change NFS parameters. In syntax description below <> means a value while [] describe optional parameters.

I2C

The NVS parameter "i2c_config" set the I2C's gpio needed to enable. Leave it blank to disable I2C usage. Note that on SqueezeAMP, port must be 1. Syntax is

sda=<gpio_num>,scl=<gpio_num>,port=0|1

Display

The NVS parameter "display_config" sets the parameters for an optional display. Syntax is

I2C|SPI,width=<pixels>,height=<pixels>[,address=<i2c_address>][,HFlip][,VFlip]

• VFlip and HFlip are optional can be used to change display orientation

The NVS parameter "metadata_config" sets how metadata is displayed for AirPlay and Bluetooth. Syntax is

[format=<display_content>][,speed=<speed>]

• 'speed' is the scrolling speed in ms (default is 33ms)

• 'format' can contain free text and any of the 3 keywords %artist%, %album%, %title%. Using that format string, the keywords are replaced by their value to build the string to be displayed. Note that the plain text following a keyword that happens to be empty during playback of a track will be removed. For example, if you have set format=%artist% - %title% and there is no artist in the metadata then only
