add() [7/8]

fl::vector< fl::ChannelPtr > CFastLED::add ( fl::span< const fl::ChannelConfig > configs )

static

Add multiple LED channels from a config array.

Creates and registers multiple Channel-based LED controllers from an array of configurations. Returns a vector of shared_ptrs for lifetime control.

Parameters

configs

Span of ChannelConfig objects

Returns

Vector of ChannelPtrs (one per config), or empty elements if unsupported

Note

Supported platforms: ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6, ESP32-P4

Example:

auto timing = fl::makeTimingConfig<fl::TIMING_WS2812_800KHZ>();
fl::ChannelConfig configs[] = {
    fl::ChannelConfig(PIN1, timing, leds1, RGB),
    fl::ChannelConfig(PIN2, timing, leds2, RGB)
};
auto channels = FastLED.add(fl::span<const fl::ChannelConfig>(configs, 2));
