?
hallo
ich begine erst mal was ich habe:
-Versuchsplatine, wo der PIC p18f1320 angeschlossen wird.
-eine Platine mit einer 4x7segment-Anzeige die über Multiplexing-Methode angesteuert wird
-einen DCF77 empfänger
Mein Freund und ich sollen alle 20 sec die anzeige wechseln lassen von min/std zu tag/monat zum Jahr anzeigen lassen.
Jedoch haben wird das problem das nix richtiges angezeigt wurd. und noch nicht mal die Synkronikation klapt da er sich zu oft zwischen drin resetet da er nicht alle werte die ankommen annimmt und ab und zu soagr werte annimmt die nicht da sind (mit Osziloskop nach geprüft)
(meiste zeit liegt 0,13V an steigt auf 4,6V für 100 oder 200 ms)
würde mich freuen wenn jemand wüsste wo dran es liegen könnte.
