This application interfaces a DCF77 receiver module to a BASIC Stamp® microcontroller. The DCF77 module receives time information from the standard time transmitter in Mainflingen, Germany. The BASIC Stamp module converts this information to RS-232. Each second it output’s a complete time string at 2400 bps.
DCF77 is a longwave time signal and standard-frequency radio station. Its primary and backup transmitter are located in Mainflingen, about 25 km south-east of Frankfurt, Germany. It is operated by T-Systems Media Broadcast, a subsidiary of Deutsche Telekom AG, on behalf of the Physikalisch-Technische Bundesanstalt, Germany’s national physics laboratory. DCF77 has been in service as a standard-frequency station since 1959; date and time information was added in 1973.
