Description
***********



.. code-block:: none

   Worldsemi WS2812 LED strip driver based on RaspberryPi Pico's PIO

   This driver not configure output pin.
   Need to configure the pins with pinctrl in parent node.

         * - Name
           - Type
           - Details

         * - ``output-pin``
           - ``int``
           - .. code-block:: none

                Set the pin number to output.



             This property is **required**.

         * - ``frequency``
           - ``int``
           - .. code-block:: none

                Specify the number of times a waveform representing 1 bit is
                transmitted per second. It is same meaning as bit-per-seconds.
                WS2812 works with 800000.
                Set the value 400000 for WS2811, 2000000 for WS2813 and WS2815.



         * - ``chain-length``
           - ``int``
           - .. code-block:: none

                The number of devices in the daisy-chain.



             This property is **required**.

         * - ``color-mapping``
           - ``array``
           - .. code-block:: none

                Channel to color mapping (or pixel order).

                For example a GRB channel to color mapping would be

                   color-mapping = <LED_COLOR_ID_GREEN
                                    LED_COLOR_ID_RED
                                    LED_COLOR_ID_BLUE>;



             This property is **required**.

         * - ``reset-delay``
           - ``int``
           - .. code-block:: none

                Minimum delay to wait (in microseconds) to make sure that the strip has
                latched the signal. If omitted, a default value of 8 microseconds is used.
                This default is good for the WS2812 controllers. Note that despite the
                WS2812 datasheet states that a 50 microseconds delay is required, it seems
                6 microseconds is enough. The default is set to 8 microseconds just to be
                safe.



             Default value: ``8``

   .. group-tab:: Base properties

      Properties inherited from the base binding file, which defines
      common properties that may be set on many nodes. Not all of these
      may apply to the "worldsemi,ws2812-rpi_pico-pio" compatible.
