DCC-EX supports both wired and wireless network connections. We will discuss using a wired Ethernet connection here. To connect using a WiFi board, see the Wifi Boards Section
To use Ethernet instead of WiFi, follow these simple steps:
Stick your Ethernet shield onto the stack with your Mega and Motor Shield
Open your config.h file in your editor (like the Arduino IDE)
Uncomment the line
"#define ENABLE_ETHERNET = true"by removing the “//” characters
Add “//” comment lines in front of
"#defind ENABLE_WIFI = true"(if it isn’t already commented out).
Enter the SSID for your router by replacing “Your network name” with the name of your network in
#define WIFI_SSID "Your network name"in between the quotes.
Enter the Password for your router by replacing “Your Network Passws” with your password in the line:
#define WIFI_PASSWORD "Your network passwd"in between the quotes.
Arduino Network Shield 2¶
There have been different revisions for the Arduino Network Shields, the main difference is the version of the WiFi chip on the board. The “2” board uses the Wiznet W5500, other versions used the older W5100 chip. The only supported chip currently is the W5500, but the other boards may work as well. The W5500 can handle 8 simultaneous socket connections while the W5100 can handle 4. These boards provide a network (IP) stack capable of both TCP and UDP. This board also has an SDCard which can be used for your own custom features or for storing settings with a possible future version of DCC++ EX
This is a micro Ethernet board no bigger than the RJ45 connector it is attached to. You have to wire this with jumpers or solder it to a prototyping PCB.
Sunfounder Ethernet Shield¶
We haven’t tested this one yet, but it looks like it should work. It is less expensive than the Arduino brand-name board and based on the Wiznet W5100 instead of the W5500. If you test this board, please let us know your results.
Nano Ethernet Shield¶
This board actually works with an Arduino Nano, you can plug your Nano directly onto this board or create a stack with the matching motor shield. This board will work with an Uno or Mega also, but you have to connect it with jumpers.
