Hallo,
für mein 240x128 Lcd mit T6963C Controller benutze ich die Sub´s von Evert Dekker. Probleme habe ich mit dem 16x16 Font. Wenn ich einen Text mit 16x16 Font schreibe, dann sehe ich aber nur 16x8 Pixel. Also der Text wird in der Mitte abgetrennt. Ich sehe nur den die hälfte der 16 Pixel. Wenn ich den Text aber um 180° drehe, dann wird er zwar auf dem kopf dargestellt, aber dafür in 16x16 Pixel. Ich kann mir keinen Reim draus machen, was für unterschiede zwischen der Funktion 0° Drehung und 180° Drehung bestehen. Wäre super, wenn Ihr mal über den Code drüber schauen könntet und mir vielleicht helfen würdet.
