|
||
The LEDC output component exposes a `LEDC PWM
|
||
channel <https://esp-idf.readthedocs.io/en/latest/api-reference/peripherals/ledc.html>`__
|
||
of the ESP32 as an output component.

|
||
# Example configuration entry
|
||
output:
|
||
- platform: ledc
|
||
pin: 19
|
||
id: gpio_19
|
||
|
||
Configuration variables:
|
||
------------------------
|
||
|
||
- **pin** (**Required**, :ref:`config-pin`): The pin to use LEDC on. Can only be GPIO0-GPIO33.
|
||
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
||
- **frequency** (*Optional*, float): At which frequency to run the LEDC
|
||
channel’s timer. Two LEDC channels always share the same timer and
|
||
therefore also the same frequency. Defaults to 1000Hz.
|
||
- **bit_depth** (*Optional*, int): The bit depth to use for the LEDC channel. Defaults to 12.
|
||
- **channel** (*Optional*, int): Manually set the `LEDC
|
||
channel <https://esp-idf.readthedocs.io/en/latest/api-reference/peripherals/ledc.html#configure-channel>`__
|
||
to use. Two adjacent channels share the same timer. Defaults to an automatic selection.
|
||
- All other options from :ref:`Output <config-output>`.
