// ---------------------------------------------------------------------------
|

|
//
|

// The LVA has a single logical LED backend that reflects the internal
|
||||||
|
// voice states (idle/listening/thinking/responding/error) and mic mute.
|

|
||||||
|
// "led_type" selects WHICH hardware is used:
|
||||||
|
// - "dotstar" = external APA102/DotStar strip
|
||||||
|
// - "neopixel" = external WS281x/NeoPixel strip
|
||||||
|
// - "xvf3800" = use the XVF3800 built-in LED ring via USB control
|
||||||
|
//
|
||||||
|
// "interface" is only meaningful for dotstar/neopixel:
|
||||||
|
// - "spi" = hardware SPI (e.g. for APA102 strips)
|
||||||
|
// - "gpio" = bit-banged output on GPIO pins
|
||||||
|
//
|
||||||
|
// For "xvf3800", LEDs are always controlled over USB; "interface",
|
