Hi I have a little project to display time on a DMD. Now I have a Etherten and have carried out the test programs to board. When I try and copy a script being the demo Clock4DMDworldclock I run the script and get the error DMD does not a have a name type. What am I doing wrong.
Thanks Locky.

Hi Locky,

For DMD-based sketches (programs) to work the DMD library needs to be correctly installed.

To check if it is installed, open the Arduino IDE and look under File menu -> Examples. Is there an entry "DMD" in the submenu list? If not, the DMD library is not correctly installed.

The instructions for installing the DMD library can be found here:

And here is a general guide to installing Arduino libraries:

Regards,

Angus

Have another question I have hooked up the real time clock and display and was now looking for a sketch to display real time on the DMD, any ideas.
Thanks Locky.
