A Proof Of Concept attempt to get accurate(ish) time from an NTP server. The result gives the time within +-10 milliseconds of the time as referenced to the DCF77 time signal from Frankfurt, Germany.

While the build in GPS works well, it can be an issue within well insulated home to receive GPS/ DCF signals from the outside. Hence the wish to add NTP with the needed hardware and code to get a ...

Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum ...
