Hi,
I don't understand how to correctly integrate the AO 01-08 (0-10V) as DAC output in the ESPHome yaml.
Could you please show me an example programme?
Many thanks in advance
our demo config yaml file already create the analog output.
here:
light:
- platform: monochromatic
name: "a4s-Color-LED-1"
output: PWM0
- platform: monochromatic
name: "a4s-Color-LED-2"
output: PWM1
- platform: monochromatic
name: "a4s-Color-LED-3"
output: PWM2
- platform: monochromatic
name: "a4s-Color-LED-4"
output: PWM3
- platform: monochromatic
name: "a4s-Color-LED-5"
output: PWM4
- platform: monochromatic
name: "a4s-Color-LED-6"
output: PWM5
- platform: monochromatic
name: "a4s-Color-LED-7"
output: PWM6
- platform: monochromatic
name: "a4s-Color-LED-8"
output: PWM7
you can click a4s-Color-LED-1 --- a4s-Color-LED-8 ico in home assistant dashboard, then will show the slide bard, that for output dc 0-10v
Thank you for the example. But unfortunately the output does not behave linearly.
If I set 50% in HA, I only get 2.5V.
Could you please show an example of how to make the output linear ( 0% = 0 V / 50% = 5 V / 100% = 10 V).
i got same problem in HA. Any solution ?? plsss
ok, when have free time, make a demo code for DAC.
This is the code. At the moment I only use input 1 with dimer 1. At 50% in HA ... I have 2.4 V. It is not linear. In a demonstration on YouTube made by you, I saw that the same thing happens to you.[

there days during China National Holidays, when we begin work, we will test it.
Any news about my request ?
ok, next week will test it.
it's normal with different voltage we have tested. PWM 50% 100% not linear.
if you want voltage higher, you can modify the "frequence",
