Hi There,

I'm trying to use IO16, on the ESP-WROVER-KIT but I can't seem to make it work. Configuring it as a output and pulsing the line I don't see anything on the scope. Other pins work fine.

I read this pin is used by the PSRAM: https://docs.espressif.com/projects/esp ... r-kit.html

Is this a usable pin on the ESP-WROVER-KIT? If so, what can I do to use it?

Thanks!

Hi oklambdago,

IO16 (and IO17) is not available for the reason you mentioned, please see a note under https://docs.espressif.com/projects/esp ... l#overview

Thanks for the quick response!
