Oups, I do not know why I missed this question... here is a late answer you may read 'same port' in the sense of 'same to each other'
It is fairly straight forward to use different pins as long as they are not on two different hardware ports. This is because the software can then change the RE/WE mode atomically with a single instruction.

Hi,
Is it possible to use different pins to D10 & D11 like D2 & D3? For my project I use SPI which conflicts on D11 and also, D2 & D3 are right next to TX/RX pins and makes for a tidier circuit and eventually PCB layout.
I see the pins are set in HardwareSerialRS485_Helper.h but it talks of using the same port, is that both pins need to be on the same port as each other, or the same port as something else?
Thanks Tom
