I will be using the HDSP-2533, which is the same display, only in Green instead of Red. (red is a little hard on my eyes).

Compare that with 10 times a second with GPS. That's what I meant by accuracy.<br /><br />As far as "how to combine dot matrix/sevseg output with the dcf77 data", I imagine that you only have to set the time values after you receive the time.<br />For example, your clock already uses variables hours, minutes, seconds to display the time. Normally, your clock also reads these values from RTC. Once in a while (e.g. every hour or even once a day), you read the data from DCF and set these variables.<br />(I assume you are still using an RTC.)<br />FlorinChttps://www.blogger.com/profile/04330573900125042405noreply@blogger.comtag:blogger.com,1999:blog-1523577297508817869.post-6156688729236713582014-07-19T13:14:35.866-04:002014-07-19T13:14:35.866-04:00RE: GPS may be better and easier:
