Hi Folks,

My topic is the DCF-77 application which makes my hair stand up...

A DCF Receiver is connected to PortD.3 and i just looked about the incoming raw data. But not as expected, these data are completely confusing Rolling Eyes me.
I checked with Scope the pulse train in timing and amplitude and both arguments are ok, a clean 5Vpp pulse train without spikes or extra pulses.
Receiving conditions are ok, no interfering sources in the area.


I kindly would ask you to checkout the following logs, the print order is:

print Time(dcf_sec) ; " " ; Date(dcf_day) ; " " ; Bin(dcf_status) ; " " ; Bin(dcf_bits) ; " " ; DCF77Timezone()


I have done tree tests:

1. Test with Inverted = 0,
2. Test with inverted = 1,
3. last log is snipped while running after one hour


DCF is configured as usual:

Config Dcf77 = PinD.3 , Timer = 1 , Inverted = 0 , Check = 2 , Update = 0 , Timer1sec = 0 , Debug = 1 , Gosub = sectic
Config Date = Dmy , Separator = .


Thats it! But look below what confusing data comes and i have really NO clue whats going on, where my possible mistake can be.

I use the ELV module DCF-77 Receiver https://de.elv.com/dcf-empfangsmodul-dcf-2-091610


I thank you in advance for any comments or assistance how to solve. Simplest error could be between the ears Razz so please help!
