        The driver can use on ESP32x SoCs either the Remote Control (RMT)
        peripheral or a bit-banging software implementation to generate the
        RGB LED signal. Using the RMT peripheral requires more ROM and RAM but
        does not use the CPU to generate the RGB LED signal. Disable this
        option if saving ROM and RAM is required.

        Use the bit-banging software implementation to generate the RGB LED
        signal.

      Indicates that a WS2812/SK6812 RGB LED sensor is present.
