add() [3/8]

fl::vector< fl::ChannelPtr > CFastLED::add ( const fl::MultiChannelConfig & multiConfig )

static

Add multiple LED channels from a MultiChannelConfig.

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

Parameters

multiConfig

MultiChannelConfig containing multiple channel configurations

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::MultiChannelConfig multiConfig = {
    fl::ChannelConfig(PIN1, timing, leds1, RGB),
    fl::ChannelConfig(PIN2, timing, leds2, RGB)
};
auto channels = FastLED.add(multiConfig);
