PCA9685 PWM Component
=====================

:description: Instructions for setting up PCA9685 LED PWM drivers.

The PCA9685 component represents a PCA9685 12-bit PWM driver
(`datasheet <https://esp-idf.readthedocs.io/en/latest/api-reference/peripherals/ledc.html#configure-channel>`__,
`adafruit <https://www.adafruit.com/product/815>`__) in esphomelib. It
uses :ref:`I²C Bus <i2c>` for communication.
To use the channels of this components, you first need to setup the
global ``pca9685`` hub and give it an id, and then define the
:doc:`individual output channels </esphomeyaml/components/output/pca9685>`.
.. code:: yaml
# Example configuration entry
pca9685:
frequency: 500
# Individual outputs
output:
- platform: pca9685
pca9685_id: 'pca9685_hub1'
channel: 0
Configuration variables:
------------------------
- **frequency** (**Required**, float): The frequency to let the
component drive all PWM outputs at. Must be in range from 24Hz to
1526Hz.
- **address** (*Optional*, int): The I²C address of the driver.
Defaults to ``0x00``.
- **id** (*Optional*, :ref:`config-id`): The id to use for
this pca9685 component. Use this if you have multiple PCA9685s connected at the same time
