Hi,
just got my first teensy 3.6 a week ago and wanted to connect an ILI9341 (16bit) TFT display to it. But I run into some problems. The UTFT library installed by Teensyduino seems to be very old and does not support my display, so I installed the latest UTFT library from Rinky-Dink Electronics (http://www.rinkydinkelectronics.com/library.php?id=51) witch does support it, but all I get are errors if I try to compile it:

Code:
#include "UTFT.h"

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}
Error messages:

Code:
Arduino: 1.8.11 (Windows 10), TD: 1.50, Board: "Teensy 3.6, Serial + MIDI, 180 MHz, Faster, German"

Fehler beim Kompilieren für das Board Teensy 3.6.

Dieser Bericht wäre detaillierter, wenn die Option
"Ausführliche Ausgabe während der Kompilierung"
in Datei -> Voreinstellungen aktiviert wäre.
Is there a way to get this UTFT version running, or is a working version available anywhere?

Sorry for this newbee questions...
