Analog Pin for output

[Analog_PIN]

Good Morning,

have we possible way for set GPIO PIN as Analog Pin out for examaple

0 until 3.3V by write a Value 0x00 until 0xFFFF / 0xFF

0 until 1.0V by write a Value 0x00 until 0xFFFF / 0xFF

Can you give a example how GPIO must be setting?

Thank you!

hey, each GPIO pin(gpio0-gpio15) can generate a shared first-order sigma-delta signal , for DAC, so that we can add some capacity to get an average analog voltage.
Change the frequency and duty of the sigma-delta signal to set the avg voltage.

Thank you Costaud, can u say me, which SDK i need minimum, because 0.9.3 is not work with the example in your link.

Thank you!
