[Udo] decided to build a clock using the DCF77 radio module seen above. This of course has been done before: the hardware draws a clock signal from the atomic clock in Braunschweig, Germany. So he ...

This repository contains a DCF77 decoder library for Arduino. It was designed with the goal to create the most noise resilent decoder possible. There are also some ready to run examples. For the ...

A popular project among microcontroller aficionados is to build a radio-controlled clock. Tiny receiver boards are available, with a pre-adjusted ferrite antenna, that receive and demodulate the DCF77 ...

The DCF77 library adds the ability to read and decode the atomic time broadcasted by the DCF77 radiostation. With the included Time library, you can run the SyncProvider sketch example.

About 20 years ago I recycled and modernized a very old nixie clock built by my father in the 70's, with an 87C51 and a DCF77 module which replaced digital ICs and 50Hz derived timebase. About 20 ...

Based on an Atmel AVR microcontroller with 8kB flash, the LED clock uses a German time signal in the form of DCF77 Receiver as it was connected to an Ethernet network to serve as a NTP server while ...

A clock design in a FPGA written mostly in VHDL. I have two designs available. Both are synthesized to a Altera MAX FPGA EPM1270T144C5, JTAG programmable, Quartus Design and simulated in Modelsim, but ...
