Be Patient ... I am in the process of setting up a NUCLEO-F446ZE. WiFi works with ESP8266 or ESP32. However, mDNS does not work with the ESP32. The IP address must be used there at the moment. I have adjusted the power display on the screen. Due to the new functions in the TrackManager, the old display no longer worked properly. I have also started to integrate various definitions for the config.h. But this still needs to be adjusted, it is not yet optimal.
- Display in DC operation: used LocoAdress is displayed
- Keypad with I2C Expander MPC23017 to operate the track manager, track voltage on/off
- Serial transmission with radio module HC-12
I designed a case for Nucleo 144 boards.
The 3D printing files can be found on Thingiverse:

Affects the following boards - at the current time (February 2025) :
- NUCLEO F413ZH
- NUCLEO F429ZI
- NUCLEO F446ZE
- NUCLEO F412ZG
- NUCLEO F439ZI
- NUCLEO F4X9ZI
Serial ports 6 and 2 are available for use with external WiFi from the source code:
#define SERIAL1 Serial6
#define SERIAL3 Serial2
eg: https://de.aliexpress.com/item/1005006357395269.html
The 2.4'' display works without changes with the SSD1306 settings
// SSD1306: 0.96'' OLED: 128,64 OR SSD1309: 2.4'' 128,64
#define OLED_DRIVER 128,64
// max 8 Lines - default are 7
#define MAX_CHARACTER_ROWS 9
The default setting for the number of lines is max:7 This display can show 8 lines. This setting must be set for this:
// max 8 Lines - default are 7
#define MAX_CHARACTER_ROWS 9
- Display IP address and port on the same line
- Show Fastclock in readable form on the display
- new ExRail Commands
- new Power Presentation on Display for the new options (DC) in the track manager the display no longer works
To make the settings easier to find, the files config.h and myAutomation.h have been moved to the 'Settings' folder.
- IF_POWER(TRACK) - is Track powered on/off
- IF_TRACK(TRACK) - is Track available
- IF_TRACK_MODE(TRACK, MODE) - is SET Mode on Track
define your button in config.h:
// Hardware Button, used with EX-RAIL
#define EMERGENCY_BUTTON 26 // Arduino Pin #2
put in myAutomation.h
/* Emergency Stop */
#ifdef EMERGENCY_BUTTON
AUTOSTART SEQUENCE(102)
IF(EMERGENCY_BUTTON)
AT(-EMERGENCY_BUTTON)
SET_POWER(ALL,OFF)
ENDIF
FOLLOW(102)
DONE
#endif
define your button in config.h:
// Hardware Button, used with EX-RAIL
#define POWER_BUTTON_A 26 // Arduino Pin #2
put in myAutomation.h
/* Toggle Power Button A */
#ifdef POWER_BUTTON_A
AUTOSTART SEQUENCE(101)
IF(POWER_BUTTON_A)
AT(-POWER_BUTTON_A)
// 'ALL' cannot be used here
IF_POWER(A)
SET_POWER(A,OFF)
ELSE
SET_POWER(A,ON)
ENDIF
ENDIF
FOLLOW(101)
DONE
#endif
New display format for the power display: Due to the new functions in the Track Manager, the conventional power display no longer works. If DC is selected, the display is no longer correct.
// Alternative View Power
#define LCD_ADVANCED_POWER
// Shows IP and Port on Display in a single line
#define PRINT_IP_PORT_SINGLE_LINE
// FastClock in HH:MM on Display
#define FASTCLOCK_READABLE

This repository, CommandStation-EX, contains a complete DCC-EX EX-CommmandStation sketch designed for compiling and uploading into an Arduino Uno, Mega, or Nano.
To utilize this sketch, you can use the following:
- (recommended for all levels of user) our automated installer
- (intermediate) download the latest version from the releases page
- (advanced) use git clone on this repository
Refer to our web site for the hardware required for this project.
We seriously recommend using the EX-Installer, however if you choose not to use the installer...
- Open the file
CommandStation-EX.inoin the Arduino IDE or Visual Studio Code (VSC). Please do not rename the folder containing the sketch code, nor add any files in that folder. The Arduino IDE relies on the structure and name of the folder to properly display and compile the code. - Rename or copy
config.example.htoconfig.h. - You must edit
config.haccording to the help texts inconfig.h.
