Integrated per-LED rendering into the existing effect/state pipeline:
solid/off uses ring frames directly,
blink toggles between frames (color ↔ off),
pulse now rewrites LED_RING_COLOR with scaled RGB per step (instead of relying on global brightness),
spin uses a single “dot” moving around the 12 LEDs.
Ensured the controller uses the XVF3800’s fixed ring size (12) where appropriate.
Fixed the “stuck in Responding” issue by subscribing the voice_idle handler so Idle effects reapply correctly when returning to IDLE.
Keeps all existing DotStar/NeoPixel behavior intact.
Adds a USB-based XVF3800 backend using the legacy LED controls (LED_EFFECT, LED_BRIGHTNESS, LED_SPEED, LED_COLOR).
Plugs it into LedController by treating "led_type": "xvf3800", "interface": "usb" as a new backend.
Wrap the board import in a try/except and introduce a _BOARD_AVAILABLE flag.
If board (or Blinka/platformdetect) is not available or fails, log a clear warning and skip hardware LED initialization.
Keep the event subscriptions intact, but ensure all LED actions become no-ops when _is_ready is False.
__init__ was completely rewritten to be decoupled. It now receives loop, event_bus, config, and preferences directly and no longer has any reference to ServerState.
Refactored for Full Configurability: The controller has been re-architected to remove all hard-coded effects and colors.
Central Configuration: It now uses a central configs dictionary to store the effect, color, and brightness settings for each voice assistant state (idle, listening, etc.).
Dynamic State Management: Subscribes to new set_<state>_effect and set_<state>_color events from the event bus to update its configuration in real-time.
Applies Custom Effects: The main voice event handlers (voice_stt_start, voice_stt_end, etc.) have been simplified to look up the user's chosen configuration and apply it.
New Animations: Implements a full suite of animations (Slow/Medium/Fast Pulse, Slow/Medium/Fast Blink, Spin) to be used by the effect selectors.
Subscribes to the new mic_muted and mic_unmuted events.
Provides visual feedback by setting the LEDs to a solid dim red when muted and calling the idle state handler (turning the LEDs off) when unmuted.
