MAC Address of Controllino
-
Hi Controllino fans, where can I find MAC address of my Controllino?
Thank you for response.

Hi Tomas,
WIZnet chipset W5100 has no fixed, or assigned MAC address, so the CONTROLLINO is sold without a MAC address.
Until the CONTROLLINO is not online and operated just in the LAN, it is not necessary to have a unique MAC address.
If you really need a unique MAC address for your CONTROLLINO, please contact us at info@controllino.com.
Thanks,
Lukas

Hi Lukas,
I am facing some troubles in running DhcpAdressPrinter, I constantly get back “Ethernet shield was not found. Sorry, can’t run without hardware. :(“
Ethernet seems to be correctly connected in IPv4. As I reccon, I don’t have to fill in any MAC adress in the code, and I am using “Ethernet.init(10);”
Could you help me solve this?
Best regards,
Wouter Mets

Lukas,
I am ALSO having the identical problem that w-mets has described above ==> I run the DHCPAddressPrinter verbatim as you described in the Tutorial and I get the same replay w-mets did: “Ethernet shield was not found. Sorry can’t run without hardware.”
However, I did NOT uncomment ANY of the “Ethernet.init(?)” lines at all.
respectfully,
Bri-Guy

Never mind Lukas I think I figured it out.
The DhcpAddressPrinter sketch requires that the Controllino have an physical ethernet cable connection to a router or a device that has a DHCP server that can SUPPLY an IP address to the Controllino and then you can see what address is assigned by the router to the Controllino in the Serial Monitor.
I hope this helps you w-mat in figuring out why the program was giving you that message.
