fl::ChannelConfigOf< Chipset > Struct Template Reference

Detailed Description

template<typename Chipset>
struct fl::ChannelConfigOf< Chipset >

Strongly-typed channel configuration with compile-time chipset family.

ChannelConfigOf<Chipset> is the Phase 3b (issue #2428) templated form of ChannelConfig. It carries the same payload as a ChannelConfig but encodes the chipset family (ClocklessChipset or SpiChipsetConfig) as a template parameter so that FastLED.add<Bus, Chipset>(cfg) can:

• Deduce Chipset from the configuration without a runtime variant probe.
• static_assert that the named Bus supports Chipset at compile time via BusSupports<B, Chipset>.
• Reject nonsense combinations (e.g. clockless config routed to an SPI-only bus) at compile time rather than at runtime.

Implicit conversions to/from the non-template ChannelConfig preserve backward compatibility – existing Channel::create(cfg) callers and the non-template FastLED.add(cfg) overloads continue to work unchanged.

Template Parameters

Chipset

One of fl::ClocklessChipset or fl::SpiChipsetConfig.

Public Member Functions
	ChannelConfigOf (const Chipset &chipset, fl::span< CRGB > leds, EOrder rgbOrder=RGB, const ChannelOptions &options=ChannelOptions()) FL_NOEXCEPT
	Construct from a typed chipset, LEDs span, and optional metadata.
	ChannelConfigOf (const fl::string &name, const Chipset &chipset, fl::span< CRGB > leds, EOrder rgbOrder=RGB, const ChannelOptions &options=ChannelOptions()) FL_NOEXCEPT
	Named-channel constructor.
	operator ChannelConfig () const FL_NOEXCEPT
	Implicit conversion to the type-erased ChannelConfig so the existing non-template Channel::create() factory accepts a templated config without any per-call-site change.
ChannelConfig	toErased () const FL_NOEXCEPT
	Convenience: build the erased form by value (handy in templates where the implicit conversion is suppressed by overload rules).

Public Attributes
Chipset	chipset
	Typed chipset configuration.
fl::span< CRGB >	mLeds
	LED data span.
fl::optional< fl::string >	mName
	Optional user-specified name. If unset, Channel auto-generates one.
fl::ScreenMap	mScreenMap
	Screen mapping (for JS canvas visualization).
ChannelOptions	options
	Optional channel settings (correction, temperature, dither, rgbw, affinity).
EOrder	rgb_order = RGB
	RGB channel ordering.
