Can ADC work in deep-sleep mode?

Postby jeromeh » Wed Feb 22, 2017 8:30 am

I'm trying to understand if ADC can work in deep-sleep mode or not? Is there any example available if this is a supported use case?

@WiFive, I'm not quite following your words...are you saying ADC is able to work in deep sleep mode but not with ULP?

ULP is able to perform an ADC read. Not supported by existing macro instructions. Is supported by binutils, but no docs.

Thanks WiFive!

Feel it's really tough to work on ULP in such a time frame, seems to me ULP is really not a priority on ESP side currently...
