ESP 32 Pin re-mapping
Posted: Sat May 20, 2017 7:03 pm
Hello!
There is a lot of talk all over the place about the ESP-32's ability to re-map it's internal peripherals to different pins. There is not, however, very much explanation on how to actually do this (in layman's terms, anyway. Sure, there are crazy port-manipulating magic things you can do, but that's not very accessible)...
I know some hardware peripherals, like the DACs, cannot be remapped. But what about the touch sensors? The SD Card?
I'm asking because I've run out of output pins in my project... I am not, however, using the input-only pins, so, could I re-map things like the touch sensors to there instead to gain some extra pins?
If so, how can I do this?
Thanks!
