Clockless
|
|
---------
|
|
|
|
The ``fastled_clockless`` light platform allows you to create RGB lights
|
|
in ESPHome for a :ref:`number of supported chipsets <fastled_clockless-chipsets>`.
|
|
|
|
Clockless FastLED lights differ from the
|
|
:ref:`fastled-spi` in that they only have a single data wire to connect, and not separate data and clock wires.

# Example configuration entry
|
|
light:
|
|
- platform: fastled_clockless
|
|
chipset: WS2811
|
|
pin: GPIO23
|
|
num_leds: 60
|
|
rgb_order: BRG
|
|
name: "FastLED WS2811 Light"
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **name** (**Required**, string): The name of the light.
|
|
- **chipset** (**Required**, string): Set a chipset to use.
|
|
See :ref:`fastled_clockless-chipsets` for options.
|
|
- **pin** (**Required**, :ref:`config-pin`): The pin for the data line of the FastLED light.
|
|
- **num_leds** (**Required**, int): The number of LEDs attached.
|
|
- **rgb_order** (*Optional*, string): The order of the RGB channels. Use this if your
|
|
light doesn't seem to map the RGB light channels correctly. For example if your light
|
|
shows up green when you set a red color through the frontend. Valid values are ``RGB``,
|
|
``RBG``, ``GRB``, ``GBR``, ``BRG`` and ``BGR``. Defaults to ``RGB``.
|
|
- **max_refresh_rate** (*Optional*, :ref:`config-time`):
|
|
A time interval used to limit the number of commands a light can handle per second. For example
|
|
16ms will limit the light to a refresh rate of about 60Hz. Defaults to the default value for the used chipset.
|
|
- **gamma_correct** (*Optional*, float): The `gamma correction
|
|
factor <https://en.wikipedia.org/wiki/Gamma_correction>`__ for the
|
|
light. Defaults to ``2.8``.
|
|
- **color_correct** (*Optional*, list of percentages): The color correction for each channel. This denotes
|
|
the maximum brightness of the red, green and blue channel. Defaults to ``color_correct: [100%, 100%, 100%]``.
|
|
- **default_transition_length** (*Optional*, :ref:`config-time`): The length of
|
|
the transition if no transition parameter is provided by Home
|
|
Assistant. Defaults to ``1s``.
|
|
- **power_supply** (*Optional*, :ref:`config-id`): The :doc:`/components/power_supply` to connect to
|
|
this light. When the light is turned on, the power supply will automatically be switched on too.
|
|
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
|
|
- **internal** (*Optional*, boolean): Mark this component as internal. Internal components will
|
|
not be exposed to the frontend (like Home Assistant). Only specifying an ``id`` without
|
|
a ``name`` will implicitly set this to true.
|
|
- If MQTT enabled, all other options from :ref:`MQTT Component <config-mqtt-component>`.

SPI
|
|
---
|
|
|
|
The ``fastled_spi`` light platform allows you to create RGB lights
|
|
in ESPHome for a :ref:`number of supported chipsets <fastled_spi-chipsets>`.
|
|
|
|
SPI FastLED lights differ from the
|
|
:ref:`fastled-clockless` in that they require two pins to be connected, one for a data and one for a clock signal
|
|
whereas the clockless lights only need a single pin.
