Re: MX030 - Radio Clock with DCF77

It's true they are cheap and they are a bit difficult to use if you don't know anything about it.
But that's because there isn't a built ind DCF decoder that sends the data through RS232 like the GPS module.

You need to make your own decoder and this is the more complex part.

Btw, there are two types of DCF77 receivers: inverted and non-inverted output.

I hope the article will help you getting the DCF receiver to work ;).
(Also, DCF77 is GMT +1)

Cheers

Hi

Did you use an INVERTED output modue with your program?
1 in 10 people understand binary, the other one doesn't !

Hi John,

Yes mine is an inverted DCF77 module (see scope pic), but the way to decode the pulses is the same.

As the articles was on the server before the change,
perhaps DavidA would be in a position to answer that and repost if different?
