Hi all,
I want to know if it is possible to achieve DAC keeping output voltage level during the deepsleep？For example，GPIO25 kept 2V level during the deepsleep.The Pins of DAC should be RTCIO,right?Thanx!
How to keep DAC output level during deepsleep?
Re: How to keep DAC output level during deepsleep?
According to the document:
When configured as RTC GPIOs, the output pads can still retain the output level value when the chip is in
Deep-sleep mode, and the input pads can wake up the chip from Deep-sleep.
But I did not find any way to achieve this..............

You probably need ulp to use dac otherwise only latched digital outputs
