This is a component using the ESP32 RMT peripheral to drive most addressable LED strips.

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.
|
|
- **rmt_channel** (**Required**, int): The RMT channel to use. If using multiple strips, you need to use different channels.
|
|
- **ESP32**: ``0`` to ``7``
|
|
- **ESP32-S2**: ``0`` to ``3``
|
|
- **ESP32-S3**: ``0`` to ``3``
|
|
- **ESP32-C3**: ``0`` or ``1``
|
|
|
|
- **chipset** (**Required**, enum): The chipset to apply known timings from. Not used if specifying the timings manually, see below.
|
|
- ``WS2812``
|
|
- ``SK6812``
|
|
- ``APA106``
|
|
- ``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``.
|
|
- **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 sending commands as quickly as
|
|
changes are made to the lights.
|
|
|
|
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.
