ESP32-S3 input only pin?

Postby adamalfath » Sun Jun 12, 2022 3:00 pm

The S3 docs mentioned that GPIO34-39 is input only pins. I know it's applicable to ESP32, but is it also true for S3? I just realize that I already have a custom board that used that pin as SPI port (GPIO35-38 = MISO, SCK, MOSI, CS) and it works just fine. I just need confirmation.
Thank you.

The S3 doesn't have input-only pins, so I think someone forgot to remove those texts. I'll file a ticket to get this fixed. Thanks for bringing this to our attention!

Thanks for the clarification...but the docs still say "input only" in 2 places on this page (one shown here):

Hm, must have been overlooked. Lemme see where that ticket went; thanks for noticing.

Okay, it seems we can't trivially fix this as these docs are generated from the header files. We decided on the 'ESP32:' bit to indicate this only goes for the original ESP32 chips.
