This Arduino library decodes (NMRA) Digital Command Control (DCC) messages. It is primarily intended for accessory Decoders and runs on ATMega processors. It has many optimizations to provide superior performance and reliability on the newer ATMega processors, such as the 4809 (Arduino Nano Every, MegaCoreX) and the AVR-DA/DB (DxCore) processors.
In this release an error was corrected that could occur in certain situations with RailCom activated and MegaXCore / DxCore microcontrollers.
