Decoding the DCF77 longwave time signal
DCF77 is a longwave radio signal which is widely used in Germany for time synchronization of clocks and watches.
This example implements the decoding of the DCF77 signal in Blech on bare metal using an STM32 discovery board .
A blog post accompanies the implementation, which explains the implementation details and the simplicity of the structured synchronous top-down design.

Thank you very much @mterber for this fine piece of work.
