Abstract

The DCC (Digital Command Control) protocol is a standard used in model railroading to control individual locomotives or accessories by modulating the track supply voltage. The commands to the trains are generated by a DCC unit that we are going to implement in the FPGA of the Nexys card, in the form of a mixed hardware/software system Thanks to a user interface created using the buttons of the Nexys card, the FPGA must generate a digital control signal. This command must then be amplified in current using a Booster card, to obtain a signal powerful enough to be sent on the rails and then be decoded by the locomotives.
