ESP8266 Software PWM Output
|
|||
|
|
===========================
|
|||
|
|
|
|||
|
|
The ESP8266 Software PWM platform allows you to use a software PWM on
|
|||
|
|
the pins GPIO0-GPIO16 on your ESP8266. As this is only a software PWM
|
|||
|
|
and not a hardware PWM (like the `ESP32 LEDC
|
|||
|
|
PWM </esphomeyaml/components/output/ledc.html>`__) and has a few
|
|||
|
|
limitations.
|
|||
|
|
|
|||
|
|
- There can be a noticeable amount of flickering with increased WiFi
|
|||
|
|
activity.
|
|||
|
|
- The output range only goes up to about 80%.
|
|||
|
|
- It’s mostly fixed to a frequency of 1kHz, you can `increase this a
|
|||
|
|
bit manually </api/output/esp8266-pwm.html#example-usage>`__ in code
|
|||
|
|
though.
|
|||
|
|
|
|||
|
|
If you need a stable PWM signal, it’s definitely recommended to use the
|
|||
|
|
successor of the ESP8266, the ESP32, and its `LEDC
|
|||
|
|
peripheral </esphomeyaml/components/output/ledc.html>`__ instead.

Configuration variables:
|
|||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|||
|
|
|
|||
|
|
- **pin** (**Required**, `Pin
|
|||
|
|
Schema </esphomeyaml/configuration-types.html#pin-schema>`__): The
|
|||
|
|
pin to use PWM on.
|
|||
|
|
- **id** (**Required**,
|
|||
|
|
`id </esphomeyaml/configuration-types.html#id>`__): The id to use for
|
|||
|
|
this output component.
|
|||
|
|
- All other options from
|
|||
|
|
`Output </esphomeyaml/components/output/index.html#base-output-configuration>`__.
