DCC++ EX is the organization maintaining several codebases that together represent a fully open source DCC system. Currently, this includes the following:
* [CommandStation-EX](https://github.com/DCC-EX/CommandStation-EX/releases) - the latest take on the DCC++ command station for controlling your trains. Runs on an Arduino board, and includes advanced features such as a WiThrottle server implementation, turnout operation, general purpose inputs and outputs (I/O), and JMRI integration.
* [exWebThrottle](https://github.com/DCC-EX/exWebThrottle) - a simple web based controller for your DCC++ command station.
* [BaseStation-installer](https://github.com/DCC-EX/BaseStation-Installer) - an installer executable that takes care of downloading and installing DCC++ firmware onto your hardware setup.
* [BaseStation-Classic](https://github.com/DCC-EX/BaseStation-Classic) - the original DCC++ software, packaged in a stable release. No active development, bug fixes only.
A basic DCC++ EX hardware setup can use easy to find, widely avalable Arduino boards that you can assemble yourself.
Both CommandStation-EX and BaseStation-Classic support much of the NMRA Digital Command Control (DCC) [standards](http://www.nmra.org/dcc-working-group "NMRA DCC Working Group"), including:
* simultaneous control of multiple locomotives
* 2-byte and 4-byte locomotive addressing
* 28 or 128-step speed throttling
* Activate/de-activate all accessory function addresses 0-2048
* Control of all cab functions F0-F28 and F29-F68
* Main Track: Write configuration variable bytes and set/clear specific configuration variable (CV) bits (aka Programming on Main or POM)
* Programming Track: Same as the main track with the addition of reading configuration variable bytes
* And many more custom features. see [What's new in CommandStation-EX?](#whats-new-in-commandstation-ex)
This repository, CommandStation-EX, contains a complete DCC++ EX Commmand Station sketch designed for compiling and uploading into an Arduino Uno, Mega, or Nano.
* WiThrottle server built in. Connect Engine Driver or WiThrottle clients directly to your Command Station (or through JMRI as before)
* WiFi and Ethernet shield support
* No more jumpers or soldering!
* Direct support for all the most popular motor control boards including single pin (Arduino) or dual pin (IBT_2) type PWM inputs without the need for an adapter circuit
* I2C Display support (LCD and OLED)
* Improved short circuit detection and automatic reset from an overload
* Current reading, sensing and ACK detection settings in milliAmps instead of just pin readings
* Improved adherence to the NMRA DCC specification
* Complete support for all the old commands and front ends like JMRI
* Railcom cutout (beta)
* Simpler, modular, faster code with an API Library for developers for easy expansion
* New features and functions in JMRI
* Ability to join MAIN and PROG tracks into one MAIN track to run your locos
* "Drive-Away" feature - Throttles with support, like Engine Driver, can allow a loco to be programmed on a usable, electrically isolated programming track and then drive off onto the main track
* Diagnostic commands to test decoders that aren't reading or writing correctly
* Support for Uno, Nano, Mega, Nano Every and Teensy microcontrollers
* User Functions: Filter regular commands (like a turnout or output command) and pass it to your own function or accessory
* Support for LCN (layout control nodes)
* mySetup.h file that acts like an Autoexec.Bat command to send startup commands to the CS
* High Accuracty Waveform option for rock steady DCC signals
* New current response outputs current in mA, overlimit current, and maximum board capable current. Support for new current meter in JMRI
* USB Browser based EX-WebThrottle
* New, simpler, function control command
* Number of locos discovery command `<#>`
* Emergency stop command <!>
* Release cabs from memory command <-> all cabs, <-CAB> for just one loco address
NOTE: DCC-EX is a major rewrite to the code. We started over and rebuilt it from the ground up! For what that means, you can read [HERE](https://dcc-ex.com/about/rewrite.html).
