50Testaufbau: \r
51\r
52Zwei Steckbretter,\r
53urspruengliche Version des Programms als Empfaenger, \r
54aktuelle Version als Sender, Aufzeichnung mit putty,\r
55angeschlossen jeweils per USB2RS232-Kabel von Conrad\r
56(972543, basierend auf Prolific PL2303). Soft-UART \r
57fuer Input, da 12F1820 keine Kontrolle ueber Input-\r
58Polaritaet erlaubt und ich fuer Testaufbauten eine\r
59Minimalbeschaltung bevorzuge.\r
60\r
61Kurze Distanz\r
62(~30 cm) zwischen Sender und Empfaenger), keine genaue Ausrichtung.\r
63Stromversorgung wahlwweise mit 5V via PICkit 2 oder 3x1.2V NiMH-AA.\r
