Hello, I am attempting to use the ILI9341_t3 library on my Teensy 4.1, but I get only a white screen and nothing else. The code used is the graphics test, but the display shows nothing but white. For a moment, it did work, but instantly went white again. All the wiring is the same as it s ays to wire it up in the demo, but I have changed the CS pin to GPIO 9 and the D/C pin to GPIO 10.
