A ez link bluetooth serial board module enables me to program the clock and read data from it remotely from my desktop pc. If you want to be sure that the output of our dcf emulator produces a valid dcf code signal, there are numerous arduino based test projects on the internet with dcf77 decoders. For my module, 1 metre is the minimum distance i have to keep the module away from lcd and pc, or the signal gets bad. Dcf77 is a time and weather transmitted located in mainflingen in germany.

I am unable to recieve one signalsecond, i get anything from 4signalssecond to 0signalssecond. This is part 3 in a small series on using dcf77 for accurate time keeping with an arduino.

It works in a very similar way to time from npl which broadcasts from the united kingdom at 60 khz the dcf77 modules that you can buy are generally simple radios.

For the arduino due the pin is usually digital pin 53. 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. Arduino forum development other software development dcf77 library for arduino synchronize with atomic. Hi erik, i just downloaded the file to my linux box and it extracted smoothly.
