The ESP32 DAC platform allows you to output arbitrary voltages using the 8-bit DAC on the ESP32. Two pins are supported: GPIO25 (Channel 1) and GPIO26 (Channel 2).
|
||
|
|
|
||
|
|
The output level is a percentage of VCC (3.3V).

# Example configuration entry
|
||
|
|
output:
|
||
|
|
- platform: esp32_dac
|
||
|
|
pin: GPIO25
|
||
|
|
id: dac_output
|

# Example usage
|
||
|
|
on_...:
|
||
|
|
then:
|
||
|
|
- output.set_level:
|
||
|
|
id: dac_output
|

Configuration variables:
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin to use DAC on. Only GPIO25 and GPIO26 are supported.
|
||
|
|
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
||
|
|
- All other options from :ref:`Output <config-output>`.
