Overview

DCC++ EX is an easy and affordable DIY DCC Command Station and related products for running an entire model railroad layout from locomotives to accessories. DCC++ EX software is free and open source and runs on low cost and easily available Arduino (and other) microcontroller hardware.

DCC++ EX (aka CommandStation-EX) is the flagship product from DCC-EX, a company created early in 2020 to address the need for an easy-to-use, easy to assemble, and inexpensive controller for model railroads. Inspired by the original DCC++, the work of Gregg E. Berman in 2014, DCC-EX took the base concept and set of commands, completely re-wrote the software from the ground up, and added many new features and enhancements.

A full system can be as simple as taking 2 boards that can be purchased for under $30, snapping them together, connecting 2 wires to the track, and operating the layout from a computer, Rasberry Pi, or phone connected with a USB cable or wireless network connection.

Components

Currently, the project has the following Components:

  • CommandStation-EX: Full-featured command station with WiThrottle support, turnout and accessory control, and general-purpose I/O, as well as tight integration with JMRI and Engine Driver. A wide variety of CABS/Throttles in addition to JMRI and Engine Driver are supported.
  • Installer–EX: Intended for beginners, this handles downloading and installing DCC++ and DCC–EX firmware onto your hardware (Arduino).
  • Throttles
  • Tools / Other
  • DCCInspector-EX: A small, inexpensive (under $15), DIY DCC Sniffer to provide complete diagnostics of exactly what data is being sent to the track.
  • BaseStation-Classic: The original DCC++ software with bug fixes only, no active development.

NMRA and RCN-212 Support

Both DCC++ EX and DCC++ Classic support the NMRA DCC Standard, including:

Additional Features

  • Diagnostics: Complete Diagnostics and Logging to quickly solve issues
  • Advanced CV Programming': Custom support for problem decoders
  • Displays: LCD or OLED Display capability
  • Built-In GPIO: Input and Output ports to connect lighting, accessories, switches, turnouts, sensors, etc. directly to the Command Station without the need for other hardware
  • EX-RAIL Automation: A simple scripting system for fully automating a layout or having signals, turnouts, lighting, respond to a locomotive or vice versa.
  • LCN: Support for the wireless "Layout Control Node" Accessory Bus System using inexpensive RF Nanos to control everything on the layout
  • HAL: A hardware Abstraction Layer that directly supports inexpensive, standard I2C servo control boards and GPIO Expander boards (for more sensors and output controls). Add support for other hardware drivers easily
  • User Function Overrides: Aka "Filters". Intercept and redirect any command and send it to your own function. Example: Send accessory commands to your own accessory bus
  • EX-JOIN: Use the service track as an extension of the MAIN track when not programming to not waste track
  • POM: Programming on Main. Any command can be sent to the Main track if needed
  • DriveAway: Place a locomotive on the service track, program it, then drive it off onto the main track
