Configuration variables
|
|
-----------------------
|
|
|
|
- **pin** (**Required**, :ref:`config-pin`): The pin for the data line of the light.
|
|
- **num_leds** (**Required**, int): The number of LEDs in the strip.
|
|
- **pio** (**Required**, int): The PIO peripheral to use. If using multiple strips, you can use up to 4 strips per PIO. Must be one of ``0`` or ``1``.
|
|
|
|
- **chipset** (**Required**, enum): The chipset to apply known timings from.
|
|
- ``WS2812``
|
|
- ``WS2812B``
|
|
- ``SK6812``
|
|
- ``SM16703``
|
|
|
|
- **rgb_order** (**Required**, string): The RGB order of the strip.
|
|
- ``RGB``
|
|
- ``RBG``
|
|
- ``GRB``
|
|
- ``GBR``
|
|
- ``BGR``
|
|
- ``BRG``
|
|
|
|
- **is_rgbw** (*Optional*, boolean): Set to ``true`` if the strip is RGBW. Defaults to ``false``.
|
|
|
|
- All other options from :ref:`Light <config-light>`.
|
|
|
|
|
|
Manual Timings
|
|
**************
|
|
|
|
These can be used if you know the timings and your chipset is not set above. If you have a new specific chipset,
|
|
please consider adding support to the codebase and add it to the list above.
|
|
|
|
- **bit0_high** (*Optional*, :ref:`config-time`): The time to hold the data line high for a ``0`` bit.
|
|
- **bit0_low** (*Optional*, :ref:`config-time`): The time to hold the data line low for a ``0`` bit.
|
|
- **bit1_high** (*Optional*, :ref:`config-time`): The time to hold the data line high for a ``1`` bit.
|
|
- **bit1_low** (*Optional*, :ref:`config-time`): The time to hold the data line low for a ``1`` bit.
