DAC7678¶
Component/Hub¶
The DAC7678 component represents a DAC7678 12-bit 8 channel DAC with internal reference (datasheet) in ESPHome. It uses the I²C Bus 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
individual output channels.
# 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, 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 DAC7678 hub as a float output.
# Example configuration entry
dac7678:
address: 0x4A
id: dac7678_hub1
internal_reference: true
# Individual outputs
output:
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 0
id: 'dac7678_1_ch0'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 1
id: 'dac7678_1_ch1'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 2
id: 'dac7678_1_ch2'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 3
id: 'dac7678_1_ch3'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 4
id: 'dac7678_1_ch4'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 5
id: 'dac7678_1_ch5'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 6
id: 'dac7678_1_ch6'
- platform: dac7678
dac7678_id: 'dac7678_hub1'
channel: 7
id: 'dac7678_1_ch7'
Configuration variables:¶
id (Required, 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, ID): Manually specify the ID of the DAC7678 hub. Use this if you have multiple DAC7678 devices.
All other options from Output.
