I am able to use serial fullduplex with smart pin use.
But I need to do something I think should be possible I just do not really understand the documentation.
I do have one COG running using 2 smart pins for fullduplex serial. And I need another COG running fullduplex serial talking to the first one.
The simple solution is to use 2 other smartpins and connect tx/rx and vice versa with some secure resistor.
But do I need to? Shouldn't I be able to take the pins next to them and access them internal?
I feel quite helpless on what to change to use not the pin itself but its neighbor so I can run txMode on say pin 51 in one COG and rxMode on pin 52 in another but using pin 51 as input.
