This application interfaces a dcf receiver module to a BASIC Stamp. The dcf module receives time information from the standard time transmitter in Mainflingen (Germany).
The basic stamp converts this information to rs-232. Each second it output's a complete time string at 2400 bps. A description of this application can be found in Elektuur 7/8 1996.
