bus.h File Reference

Detailed Description

Compile-time identifier for an LED channel transmission bus.

fl::Bus is the single source of truth for which low-level driver implementation handles a channel. The same value drives:

• Compile-time template binding (Channel<Bus::X, Chipset>).
• Per-platform default selection (DefaultBus<Chipset>::value).
• Opt-in runtime registry enrollment (enableDrivers<Bus::X...>()).

Drivers link only when their Bus value is named somewhere in the translation unit graph. See issue #2428.
