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``.
|
||
|
|
|

|
|
# 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%
