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>`.
