DCF77 Receiver


This is a nice application for the new ATtiny22. It decode the time information and send it over the UART with 9600 baud. This example can send with a known baudrate nevertheless the internal RC oscillator was used. The trick is, that at first the internal frequency was measured by the known time of exact  1 second during 2 pulses of the atomic controlled  DCF77 time code transmitter.
