Hello, I have moved my code from arduino mega to due. Because I'm handling RS485 communication I need to receive data in interrupts - on arduino mega I used library GitHub - SlashDevin/NeoHWSerial: Arduino HardwareSerial with attachInterrupt for RX chars - which unforutently is not working on DUE. …

Arduino DUE - read serial in interupt

AFAICT RS485 is not available ON UART (Serial = Serial0). You will have to deal with Serial1,2 or 3 (Serial4 has no broken out RTS pin).
