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 ...

Using 2 ATmega328s, this clock displays and decodes the DCF77 signal using 150 LEDs and 4x 7-segment display modules on a 12" (305mm) dial. This Clock displays the DCF77 time code on 2 rings of 60 ...

Required components The first things you will need is DCF77 module and a crystal based Arduino. Attention: the Arduino Uno is NOT crystal based. Although there is a crystal on the board this crystal ...

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 ...

About twenty years ago I recycled and modernised a vintage clock with Nixie tubes built by my father in the nineteen seventies. I replaced the digital logic by a microcontroller and used a DCF77 ...

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 ...

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 ...

Measure: Frequency + Period + Pulse + Pulse/period + Capacity + Event counting. Bonus: decode DCF77 pulses and show date and time. The DCF77 pulses are also used to calibrate the system clock.
