Re: 16x4 Zeichen Display con Conrad Kategorie: Programmierung Basic (von Todi - 24.01.2006 18:49)

Todi nutzt:  CC1-Unit V1.1, CC1-M-Unit V1.1

Hi Stefan, so habe ich die Programmierung des 4x16-Displays (das "grüne-gelbe"-Display von Conrad )gelöst (so ist es recht verständlich). Habe mir auch mal ein "blaues 2x16" kommen lassen (sieht schöner aus und braucht weniger STrom), allerdings werden dort die Zeilenanfänge anders addressiert. Kannst du aber ganz leicht ausprobieren, indem du einen Test-Text mit immer anderen Adressen ausprobierst. Irgendwann passt es schließlich. Gibt aber auch beim Conrad-Kundenservice (17 80 04) ein komplettes LCD-Datenblatt (jeweils für die grün-gelbe oder blaue Version). Da stehen alle Adressen und ASCII-Codes drin. Hoffe, das hilft dir weiter...
