hallo,
ich hätte da 2 Sourcecodes für die Grafik- und Font-Ausgabe, die man exemplarisch verwenden könnte, und wie ich sie auch selber bereits mit g++ auf meinen Arduinos verwende.
Zusätzlich hätte ich noch einen dritten Source-Code (UTFT UTouch) für Touchscreen-Funktionen mit Buttons.
ein ganz einfacher Test (eigentlich ein Mini-TFT-speed-test), der nur Basisfunktionen testet (speziell für die o.s. ILI9341_due-lib) ist dieser hier:

Anm.:
teilw. benutzen die Libs eine unterschiedliche Funktions-Syntax, z.B. für Rechtecke:
ILI9341_due verwendet die Größenabgabe ab Startpunkt (x1, y1, width, height)
UTFT verwendet die diagonalen Exkpunkte (x1,y1, x2,y2)
Außerdem ist die Farb-Steuerung unterschiedlich
ILI9341_due verwendet die Farbe als Übergabeparameter,
UTFT verwendet stattdessen einen eigen Befehl SetColor().
- insgesamt aber eher unbedeutende Unterschiede, wenn man nicht gezwungen ist, immer wieder alle Codes hin und her konvertieren zu müssen.
