The BP5758D component represents a BP5758D 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 ``bp5758d`` hub and give it an id, and then define the
:ref:`individual output channels <bp5758d-output>`.
It is used in some smart light bulbs:
- DoHome G25 Globe bulb
.. code-block:: yaml
# Example configuration entry
bp5758d:
data_pin: GPIOXX
clock_pin: GPIOXX
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 ``bp5758d`` component. Use this if you have multiple BP5758D chains
connected at the same time.
.. 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 BP5758D output component exposes a BP5758D channel of a global
:ref:`bp5758d-component` as a float output.
.. code-block:: yaml
# Example configuration entry
output:
- platform: bp5758d
id: output_red
channel: 2 # Valid values 1-5 to match OUT1-OUT5
current: 10 # In mA, valid values 0-90, default 10
Configuration variables:
************************
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
- **channel** (**Required**, int): Chose the channel of the BP5758D chain of
this output component. Valid values are 1-5
**current** (*Optional*, int): Current in mA, valid values are 0-90, default 10.
- **bp5758d_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
:ref:`bp5758d-component`.
Use this if you have multiple BP5758D 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.
