May 2014 First version May 2014 First version
March 2016 - big overhaul... March 2016 - big overhaul...
July 2016 - Start with building the v2.0 Clock and adapting the sketch
Version 2.0 - August 2016
- This sketch is adapted for my 2.0 version of the DCF/Analyzer Clock. It used the Arduino MEGA and the DCF Superfilter
by default and to drive the many seperate LED's I now use the ports of an Arduino Mega instead of a Maxim 7219 chip.
This is because driving LED's with many different Voltage/Current specs is problematic with the Maxim chip.
Lighting additional LED's for expample will influence (dim) the LED's already on. As I'm not an electronics engineer
my only solution was to use the extra ports of the Arduino Mega. Ofcourse you can use transistors or extra chips to
drive the LED's but for me this was the obvious solution.
- Removed all the code to use Maxim 72xx chips with Common Anode displays
