canHandle()

bool fl::SpiChannelEngineAdapter::canHandle ( const ChannelDataPtr & data ) const

overridevirtual

Check if adapter can handle channel data.

Parameters

data	Channel data to check

Returns

true if data is true SPI chipset (APA102, SK9822, HD108)

Note

Rejects clockless chipsets (WS2812, SK6812, etc.)

Implements fl::IChannelDriver.

    // ⚠️ CRITICAL: Accept ONLY true SPI chipsets (APA102, SK9822, HD108)
    // Reject clockless chipsets (WS2812, SK6812) - those use ChannelEngineSpi or RMT
    //
    // This is the opposite of ChannelEngineSpi::canHandle(), which should be:
    //   return !data->isSpi();  // Accept clockless, reject true SPI
    //
    // Correct routing:
    //   APA102 → SpiChannelEngineAdapter (this adapter)
    //   WS2812 → ChannelEngineSpi (clockless-over-SPI) OR RMT/PARLIO
    return data->isSpi();
