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.

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>`.
