E-blocks DCF Clock

Here’s how the author used Flowcode to develop PIC software for a DCF-controlled clock suitable for the CET, CET–1 and CET+1 time zones. Dispelling the myth that Flowcode has no use outside the E-blocks environment, the end result was cheerfully ported to the famous Elektor 2002 ‘PICee’ development board.

Having successfully completed a number of ‘lesser’ projects using Flowcode, I decided to try a much more ambitious project: a DCF Atomic Clock Time and Date information Display, which also involved reading and processing pulses in a very exact manner.
