Adafruit's TLC5947 board
This component represents a chain of `TLC5947 24-Channel, 12-Bit PWM LED Drivers <https://www.ti.com/lit/ds/symlink/tlc5947.pdf>`_,
which is used e.g. on this `board from Adafruit <https://www.adafruit.com/product/1429>`_.
To use the channels of this components, you first need to setup the
global ``tlc5947`` hub and give it an id, and then define the
:ref:`individual output channels <tlc5947-output>`.
.. code-block:: yaml
# Example configuration entry
tlc5947:
data_pin: GPIO12
clock_pin: GPIO14
lat_pin: GPIO15
# Individual outputs
output:
- platform: tlc5947
id: output_red
channel: 0
- platform: tlc5947
id: output_green
channel: 1
- platform: tlc5947
id: output_blue
channel: 2
Configuration variables:
************************
- **data_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin connected to DIN.
- **clock_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin connected to CLK.
- **lat_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin connected to LAT.
- **oe_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The pin connected to /OE (BLANK).
- **num_chips** (*Optional*, int): Number of chips in the chain. Must be
in range from 1 to 85. Defaults to 1.
- **id** (*Optional*, :ref:`config-id`): The id to use for
this ``tlc5947`` component. Use this if you have multiple TLC5947 chains
connected at the same time.
.. _tlc5947-output:
Output
------
The tlc5947 output component exposes a tlc5947 channel of a global
:ref:`tlc5947-component` as a float output.
.. code-block:: yaml
# Example configuration entry
tlc5947:
data_pin: GPIO12
clock_pin: GPIO14
lat_pin: GPIO15
# Individual outputs
output:
- platform: tlc5947
id: output_red
channel: 0
- platform: tlc5947
id: output_green
channel: 1
- platform: tlc5947
id: output_blue
channel: 2
Configuration variables:
************************
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
- **channel** (**Required**, int): Chose the channel of the TLC5947 chain of
this output component.
- **tlc5947_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
:ref:`TLC5947-component`.
Use this if you have multiple TLC5947 chains you want to use at the same time.
- All other options from :ref:`Output <config-output>`.
