MCP47A1 Output
|
||||
==============
|
||||
|
||||
.. seo::
|
||||
:description: Instructions for setting up MCP47A1 outputs on the ESP.
|
||||
:image: mcp47a1.svg
|
||||
|
||||
The ``mcp47a1`` output component allows to use `6bit external DAC <https://www.microchip.com/en-us/product/MCP47A1>`__
|
||||
in order to have analog output(s) on any board by using I²C. Devices default address is ``0x2E``
|
||||
and configurable alternative is ``0x3E``.
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
# Example configuration entry
|
||||
|
||||
# Set a global I²C connection
|
||||
i2c:
|
||||
sda: 21
|
||||
scl: 22
|
||||
scan: true
|
||||
|
||||
# Set the output with default (address: 0x2E / global I²C)
|
||||
output:
|
||||
- platform: mcp47a1
|
||||
id: dac_output
|
||||
|
||||
on_...:
|
||||
then:
|
||||
- output.set_level:
|
||||
id: dac_output
|
||||
level: 100%
|
||||
|
||||
|
||||
Configuration variables:
|
||||
------------------------
|
||||
|
||||
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
||||
- **address** (*Optional*, int): Manually specify the I²C address of
|
||||
the DAC. Defaults to ``0x2E``.
|
||||
- All other options from :ref:`Output <config-output>`.
