The NmraDcc library has been updated to version 1.3.0 and contains the following significant changes:

• Thanks to Franz-Peter Müller the core DCC decoding logic no longer uses the Timer0 Compare Match B interrupt and only relies on the INTx External Hardware Interrupt and the micros() library call for DCC signal decoding. This will make the library much more portable to other non-AVR platforms in the future.

• Geoff Bunza’s SMA examples have been updated to version 5.1

You can now install or update this library from within the Arduino IDE Library Manager by searching for “dcc”
