Decoder for the DCC system to detect if tracks are occupied. Detection is performed by measuring voltage over a resistor / (high speed) diode. Feedback to the master station uses the RS-Bus

Decoder for the DCC (Digital Command Control) system with feedback of the actual switch position. via the RS-Bus. It can be used to control 4 switches or 4 relays. It is written in C for the ATMEGA 16A and similar AVRs.
