NMRA Digital Command Control (DCC) Library

This library allows you to interface to a NMRA DCC track signal and receive DCC commands.

The library currently supports the AVR ATTiny84/85 & ATMega88/168/328/32u4 and Teensy 3.x using the INT0/1 Hardware Interrupt and micros() ONLY and no longer uses Timer0 Compare Match B, which makes it much more portable to other platforms.

Warning as of version 1.4.4 support has been removed for the following two call-back functions, which will cause your sketch to silently stop working:

extern void notifyDccAccState( uint16_t Addr, uint16_t BoardAddr, uint8_t OutputAddr, uint8_t State )
extern void notifyDccSigState( uint16_t Addr, uint8_t OutputIndex, uint8_t State) 
You can’t perform that action at this time.
