hallo,
ich habe hier noch 2 ältere ILI9225 2.2" TFT displays von Ebay/China (QD-tech), damals funktionierten Original Henning Karlsen UTFT libs (Software-SPI) nicht und mussten durch gepatchte UTFT-Versionen ersetzt werden (H.K. weigert sich auch, China-Ware zu supporten).
Mit den alten IDEs (1.5.x), diesen gepatchten Libs und der Initialisierung per
UTFT myGLCD(Model, SDA=MOSI, SCL, CS, RESET, RS), z.B.
UTFT myGLCD(QD220A, A2, A1, A5, 0, A3);
funktionierte es dann aber sehr gut, man konnte die TFTs damit sogar schnell mal auf die ADC Pins auftecken, ohne großartig Kabelstrippen ziehen zu müssen.
Leider funktionieren die aber nicht mehr mit den neueren IDEs (1.8.5) - ich kriege kein Bild mehr, nur wahlloses Geflacker. Auch mit 4 anderen UTFT Libs aus dem web hatte ich bislang keinen Erfolg.
Wer kennt aus eigener Erfahrung neuere UTFT-Libs, die mit China-ILI9225 zusammen funktionieren?

Problem z.B.: vom Original Karlsen http://www.rinkydinkelectronics.com/library.php?id=52 gibt es zwar eine UTFT Lib, in der aber kein QD220A vorhanden ist, jedoch z.B. mit TFT Typ ITDB22 bzw. ITDB22SP funktionert es nicht, es blinkt nur, wie gesagt).
edit, update:
habe es doch hingekriegt: es musste in der gepatchten Lib, anders als in Karlsen-UTFT, per
UTFT myGLCD(QD220A, A2, A1, A5, A4, A3);
initialisiert werden, jetzt geht es.
ich habe hier noch 2 ältere ILI9225 2.2" TFT displays von Ebay/China (QD-tech), damals funktionierten Original Henning Karlsen UTFT libs (Software-SPI) nicht und mussten durch gepatchte UTFT-Versionen ersetzt werden (H.K. weigert sich auch, China-Ware zu supporten).
Mit den alten IDEs (1.5.x), diesen gepatchten Libs und der Initialisierung per
UTFT myGLCD(Model, SDA=MOSI, SCL, CS, RESET, RS), z.B.
UTFT myGLCD(QD220A, A2, A1, A5, 0, A3);
funktionierte es dann aber sehr gut, man konnte die TFTs damit sogar schnell mal auf die ADC Pins auftecken, ohne großartig Kabelstrippen ziehen zu müssen.
Leider funktionieren die aber nicht mehr mit den neueren IDEs (1.8.5) - ich kriege kein Bild mehr, nur wahlloses Geflacker. Auch mit 4 anderen UTFT Libs aus dem web hatte ich bislang keinen Erfolg.
Wer kennt aus eigener Erfahrung neuere UTFT-Libs, die mit China-ILI9225 zusammen funktionieren?

Problem z.B.: vom Original Karlsen http://www.rinkydinkelectronics.com/library.php?id=52 gibt es zwar eine UTFT Lib, in der aber kein QD220A vorhanden ist, jedoch z.B. mit TFT Typ ITDB22 bzw. ITDB22SP funktionert es nicht, es blinkt nur, wie gesagt).
edit, update:
habe es doch hingekriegt: es musste in der gepatchten Lib, anders als in Karlsen-UTFT, per
UTFT myGLCD(QD220A, A2, A1, A5, A4, A3);
initialisiert werden, jetzt geht es.
