init()

void CFastLED::init

(

)

Initialize platform-specific subsystems.

Performs one-time initialization of platform-specific hardware and subsystems. This is called automatically on first use but can be called explicitly to ensure initialization happens at a predictable time.

Safe to call multiple times - subsequent calls are no-ops.

Platform-specific initialization:

• ESP32: Initializes channel bus manager (PARLIO/SPI/RMT/UART) and SPI bus manager
• Other platforms: No-op (no initialization required)

                    {
    // Call platform-specific initialization once
    // Uses the trampoline pattern: platforms/init.h dispatches to platform-specific headers
    // FL_RUN_ONCE ensures this is only called once, even if init() is called multiple times
    FL_RUN_ONCE(fl::platforms::init());
