Emulator SHARP Thermodrucker CE-126P mit Arduino UNO

Dieses Arduino Programm emuliert den Sharp Thermodrucker CE-126P auf einem Arduino UNO. Mit einem Sharp Pocket Computer können damit die Standard Druckbefehle für den externen Drucker (LLIST, LPRINT) verwendet werden, um die Ausgabe über den Arduino an eine serielle Schnittstelle weiterzuleiten und z.B. am Serial-Monitor der Arduino IDE auszugeben. Unterschiedliche Modelle von Sharp Pocket Computern kommunizieren auf unterschiedliche Art und Weise mit dem Drucker CE-126P, siehe einige Beispiele unterhalb. Damit die Datenübertragung stabil läuft, ist es notwendig pull-down Widerstände (z.B. 10kOhm) von den Daten- und Steuerungsleitungen gegen GND zu schalten.

Emulator passend für folgende Sharp Pocket Computer:

PC-1250A
PC-1260, PC-1261, PC-1262
PC-1401, PC-1403, PC-E500
