Eigentlich ein Artikel für volle Punktzahl. Alles funktioniert tadellos, wenn man weiß wie. Bei der Herstellung hat sich wohl ein kleiner aber bedeutender Fehler eingeschlichen... Testprogramm geladen, Modul angeschlossen, nichts ging, alles schwarz. Spannung gemessen, ok. Datenleitung gemessen, einwandfreies Signal. Also habe ich den ersten Chip nachgelötet, Ergebnis: nichts. Ok, dann ist wohl der 1. Chip defekt habe ich gedacht und habe eine Testleitung hinter dem 2. Chip direkt auf das Board aufgelötet (siehe Foto). Normalerweise hätten jetzt 62 LED brennen sollen, aber es brannten 2! Die erste und die zweite. Dann kann der Aha-Effekt... die Beschriftung auf dem Board ist falsch. DIN ist tatsächlich der AUSGANG und DOUT ist der EINGANG. Wer kommt denn auf so was? Ob das jetzt ein Designfehler oder ein Fabrikationsfehler ist, das ist mir egal, aber normalerweise verlässt man sich darauf dass die Beschriftung auf dem Board korrekt ist. Für die 2 Stunden Fehlersuche gibt es Punkteabzug!
