+This is a fun [smartwatch](http://www.lilygo.cn/prod_view.aspx?TypeId=50036&Id=1290&FId=t3:50036:3) based on ESP32. It has a 240x240 ST7789 screen and onboard audio. Not very useful to listen to anything but it works. This is an example of a device that requires an I2C set of commands for its dac (see below). There is a build-option if you decide to rebuild everything by yourself, otherwise the I2S default option works with the following parameters
 
+- dac_config: model=I2S,bck=26,ws=25,do=33,i2c=106,sda=21,scl=22
+- dac_controlset: { "init": [ {"reg":41, "val":128}, {"reg":18, "val":255} ], "poweron": [ {"reg":18, "val":2}, "mode":"or" ], "poweroff": [ {"reg":18, "val":253}, "mode":"and" ] }
+- spi_config: dc=27,data=19,clk=18
+- display_config: SPI,driver=ST7789,width=240,height=240,cs=5,back=12,speed=16000000,HFlip,VFlip
 ### 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:
