I'm looking at making a wall world clock display using the DMD module.
So something like (these are made up times):
Code: Select all
Sydney 20:00:01 London 08:00:01 New York 14:00:01
I'm guessing I can take the example:
https://github.com/freetronics/DMD/blob ... eadout.pde
and adapt it so it actually reads the time in - I don't have my DMD yet, but that program only seems to print out static numbers, right?
So I'd need to get it to read in the time, and also do the timezone conversion. Also, I'd need to add seconds, as well as the static text for city names.
Any ideas on how to do this, and/or or caveats I should be wary of here?
Also, the device would also check it's time regularly with NTP, so I guess I'd need to also run a NTP client off the EtherTen - any thoughts on how I might achieve this? It needs to be backgrounded, somehow, right?
I should also mention I bought one of those real-time clock modules.
