Component/Hub
|
|
-------------
|
|
|
|
The SM2235 component represents a SM2235 LED driver chain in
|
|
ESPHome. Communication is done with two GPIO pins (DATA and CLK).
|
|
|
|
To use the channels of this components, you first need to setup the
|
|
global ``sm2235`` hub and give it an id, and then define the
|
|
:ref:`individual output channels <sm2235-output>`.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
sm2235:
|
|
data_pin: GPIOXX
|
|
clock_pin: GPIOXX
|
|
max_power_color_channels: 9
|
|
max_power_white_channels: 9
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **data_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin used for DATA.
|
|
- **clock_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin which CLK is
|
|
connected to.
|
|
- **id** (*Optional*, :ref:`config-id`): The id to use for
|
|
this ``sm2235`` component. Use this if you have multiple SM2235 chains
|
|
connected at the same time.
|
|
- **max_power_color_channels** (*Optional*, int 0-15): Adjusts the current supplied to the
|
|
color channels, higher is more power. Default is 2 per SM2235 datasheet. See table below.
|
|
- **max_power_white_channels** (*Optional*, int 0-15): Adjusts the current supplied to the
|
|
white channels, higher is more power. Default is 4 per SM2235 datasheet. See table below.
|
|
|
|
.. note::
|
|
|
|
The LED driver may be able to tolerate more power than
|
|
the bulb is designed to handle, start with lower values
|
|
and increase slowly, comparing to a stock bulb to verify
|
|
what is safe for your model.

Output
|
|
------
|
|
|
|
The SM2235 output component exposes a SM2235 channel of a global
|
|
:ref:`sm2235-component` as a float output.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Individual outputs
|
|
output:
|
|
- platform: sm2235
|
|
id: output_red
|
|
channel: 1
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
|
- **channel** (**Required**, int): Chose the channel of the SM2235 chain of
|
|
this output component.
|
|
- **sm2235_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
|
|
:ref:`sm2235-component`.
|
|
Use this if you have multiple SM2235 chains you want to use at the same time.
|
|
- All other options from :ref:`Output <config-output>`.
|
|
|
|
.. note::
|
|
|
|
This driver does support enabling of both the color and the white channels
|
|
at the same time, but it is not encourage. Therefore, the :ref:`rgbw_color_interlock`
|
|
should be set to true when using this driver for safest operation.
