LCD 16x2 mit I2C mit großen Zeichen

-

hallo zusammen,
ich möchte ein lcd 16x2 mit i2c mit großen zeichen über zwei zeilen betreiben. die inhalt der zeichen ändert sich ständig über eine variable. hat jemand eine vorstellung, wie ich hier beginnen könnte?
bin dankbar für jede hilfe.

soweit mir bekannt, sind nur acht frei definierbare zeichen möglich, die du ja wahrscheinlich benötigst. kommst du damit hin?
