This project contains FW for ATmega128 at Charon II developer board. It receives time synchronization signal from DCF77 radio station.
Pinout:
- RTC 8583: PD0 (SCL), PD1 (SDA), PD2 (INT)
- DCF77 receiver: PD3
Program receives time from DCF77, stores it in RTC chip and then sends it to PC. Because of missing simple buttons at developer board, new synchronization request could only be triggered via RESET.
This project was created as a final work at PV198 course @ FI MUNI, autumn 2017 by Jan Horacek.
