/* WWVB Clock v 1.0
|
||||
*
|
||||
* A WWVB (NIST Time Code Broadcast) receiving clock powered by an
|
||||
* Arduino (ATMega328), a DS1307 Real Time Clock, and a C-Max
|
||||
* C-Max CMMR-6P-60 WWVB receiver module. |
||||
* |
||||
* This code builds on Capt.Tagon's code at duinolab.blogspot.com |
||||
* which was a great reference. Specifically, I used almost without change |
||||
* his struct / unsigned long long overlay for the received WWVB Buffer,
|
||||
* which apparently in turn draws on DCF77 decoding code by Rudi Niemeijer, |
||||
* Mathias Dalheimer, and "Captain."
|
||||
* |
||||
* The RTC (DS1307) interface code builds in part on code by
|
||||
* Jon McPhalen (www.jonmcphalen.com) |
||||
* |
||||
* There you have it. |
||||
* |
||||
* This code supports the "Atomic Clock" article in the April 2010 issue |
||||
* of Popular Science. There is also a schematic for this project. There |
||||
* is also WWVB signal simulator code, to facilitate debugging and
|
||||
* hacking on this project when the reception of the WWVB signal
|
||||
* itself is less than stellar. |
||||
*
|
||||
* The code for both the clock and the WWVB simulator, and the schematic |
||||
* are available online at: |
||||
* http://www.popsci.com/diy/article/2010-03/build-clock-uses-atomic-timekeeping
|
||||
*
|
||||
* and on GitHub at: http://github.com/vinmarshall/WWVB-Clock
|
||||
*
|
||||
* Version 1.0 |
||||
* Notes:
|
||||
* - No timezone support in this version. UTC only. |
||||
* - No explicit leapsecond (3 frame marker bits) support in this version. |
||||
* - 24 hour mode only |
