Channel() [1/4]

fl::Channel::Channel ( const ChipsetVariant & chipset, fl::span< CRGB > leds, EOrder rgbOrder, const ChannelOptions & options )

private

Private constructor (use create() factory method)

Parameters

chipset	Chipset configuration (clockless or SPI)
leds	LED data array
rgbOrder	RGB channel ordering
options	Channel options (correction, temperature, dither, rgbw, affinity)
