Component/Hub
|
|
-------------
|
|
|
|
The DAC7678 component represents a DAC7678 12-bit 8 channel DAC with internal reference
|
|
(`datasheet <https://www.ti.com/lit/ds/symlink/dac7678.pdf>`__) in ESPHome. It
|
|
uses the :ref:`I²C Bus <i2c>` for communication.
|
|
|
|
To use the channels of this components, you first need to setup the
|
|
global ``dac7678`` hub and give it an id, and then define the
|
|
:ref:`individual output channels <dac7678-output>`.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
dac7678:
|
|
address: 0x4A
|
|
id: dac7678_hub1
|
|
internal_reference: true
|
|
|
|
# Individual outputs
|
|
output:
|
|
- platform: dac7678
|
|
dac7678_id: 'dac7678_hub1'
|
|
channel: 0
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **address** (*Optional*, int): The I²C address of the driver.
|
|
Defaults to ``0x48``.
|
|
- **id** (*Optional*, :ref:`config-id`): The id to use for
|
|
this dac7678 component. Use this if you have multiple DAC7678s connected at the same time
|
|
- **internal_reference** (*Optional*, bool): State of the internal reference.
|
|
Defaults to ``false``.

DAC7678 Output
|
|
--------------
|
|
|
|
The DAC7678 output component exposes a DAC7678 DAC channel of a global
|
|
:ref:`DAC7678 hub <dac7678-component>` as a float
|
|
output.

************************
|
|
|
|
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
|
- **channel** (**Required**, int): Chose the channel of the DAC7678 of
|
|
this output component. Must be in range from 0 to 7.
|
|
- **dac7678_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
|
|
:ref:`DAC7678 hub <dac7678-component>`.
|
|
Use this if you have multiple DAC7678 devices.
|
