add() [5/9]

void CFastLED::add ( fl::ChannelPtr channel )

static

Add a Channel-based LED controller (from ChannelPtr)

Registers a pre-created Channel instance with the FastLED controller list. Channels provide hardware-accelerated parallel LED output using platform-specific drivers.

Parameters

channel

Shared pointer to a Channel instance

Example:

auto timing = fl::makeTimingConfig<fl::TIMING_WS2812_800KHZ>();
fl::ChannelConfig config(PIN_DATA, timing, fl::span<CRGB>(leds, NUM_LEDS), RGB);
fl::ChannelPtr channel = fl::Channel::create(config);
FastLED.add(channel);

    }
    auto& chnls = channels();
    // Protect against double-add
    if (chnls.has(channel)) {
        return;
    }
    chnls.push_back(channel);
    // Add channel to the CLEDController linked list
    // fl::Channel uses DeferRegister mode, so explicit addToDrawList() call is required
    // Note: addToDrawList() now fires onChannelAdded event
    channel->addToDrawList();
