-------------

|
|
|
|
|
|
The PCA9685 component represents a PCA9685 12-bit PWM driver
|
|
|
|
|
(`datasheet <https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/ledc.html#configure-channel>`__,
|
|
|
|
|
`adafruit <https://www.adafruit.com/product/815>`__) in ESPHome. 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
|
|
|
|
|
:ref:`individual output channels <pca9685-output>`.
