ESP32-S3-DevKitC SPI pins
Posted: Fri Dec 23, 2022 1:32 am
Firstly, sorry if this is answered somewhere but searching the forums didn't turn anything up.
Secondly, sorry for the newb questions but I've also read many docs and haven't worked it out so asking for tips
...
The ESP32-S3-DevKitC pinout uses the same pins for FSPI and SUBSPI (apart from SUBSPICS0) so I don't understand how one would wire up both simultaneously ... do you have to map one of them to other pins (using IO_MUX or GPIO matrix)?
And, how do you tell the code that the default pins should be FSPI or SUBSPI - is it just the args to the begin(...) [like, no args for the default pins and specify the args for non-default]?
Thanks in advance, m
