Hallo.
Ich besitze ein AZDelivery 5 x 2.4 Zoll LCD TFT Touch Display 320 x 240 Auflösung, ILI9341 Treiber, SPI Schnittstelle und habe dies auch erfolgreich mit TFT_eSPI eingebunden.
Touch funktioniert, Display zeigt auch alles an, außer Umlaute.
Zudem fehlte mir eine größere Schrift.
Gefunden habe ich diese FreeFontDemo
/*
This example draws fonts (as used by the Adafruit_GFX library) onto the
screen. These fonts are called the GFX Free Fonts (GFXFF) in this library.
Other True Type fonts could be converted using the utility within the
"fontconvert" folder inside the library. This converted has also been
copied from the Adafruit_GFX library.
Since these fonts are a recent addition Adafruit do not have a tutorial
available yet on how to use the utility. Linux users will no doubt
figure it out! In the meantime there are 48 font files to use in sizes
from 9 point to 24 point, and in normal, bold, and italic or oblique
styles.
This example sketch uses both the print class and drawString() functions
to plot text to the screen.
Make sure LOAD_GFXFF is defined in the User_Setup.h file within the
TFT_eSPI library folder.
--------------------------- NOTE ----------------------------------------
The free font encoding format does not lend itself easily to plotting
the background without flicker. For values that changes on screen it is
better to use Fonts 1- 8 which are encoded specifically for rapid
drawing with background.
-------------------------------------------------------------------------
>>>>>>>>>>>>>>>>>>>>>>>>>>> WARNING <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
As supplied with the default settings the sketch has 11 fonts loaded,
i.e. GLCD (Font 1), Font 2, Font 4, Font 6, Font 7, Font 8 and five Free Fonts,
even though they are not all used in the sketch.
Disable fonts you do not need in User_Setup.h in the library folder.

Allerdings werden keine Umlaute angezeigt.
Ich möchte später empfangene Titel am Display ausgeben und kann nicht ausschließen dass Umlaute aufkommen.
In der UserSetup.h habe ich diese alle mal auskommentiert:
