Is this a correct basic sketch for LilyGo T-Display S3 Amoled? I tried many times and didn't work. It compiles and uploads correctly.

#include <Arduino_GFX_Library.h>

#define GFX_DEV_DEVICE LILYGO_T_DISPLAY_S3_AMOLED
Arduino_DataBus bus = new Arduino_ESP32QSPI(
6 / cs /, 47 / sck /, 18 / d0 /, 7 / d1 /, 48 / d2 /, 5 / d3 */);
Arduino_GFX gfx = new Arduino_RM67162(bus, 17 / RST /, 0 / rotation */);

void setup(void)
{
Serial.begin(115200);
Serial.println("Setup Started");

#ifdef GFX_EXTRA_PRE_INIT
GFX_EXTRA_PRE_INIT();
#endif

// Init Display
if (!gfx->begin())
{
Serial.println("gfx->begin() failed!");
while (1); // Halt the program
}
Serial.println("gfx->begin() success!");

gfx->fillScreen(BLACK);
Serial.println("Screen filled with BLACK");

#ifdef GFX_BL
pinMode(GFX_BL, OUTPUT);
digitalWrite(GFX_BL, HIGH);
Serial.println("Backlight turned ON");
#endif

gfx->setCursor(10, 10);
gfx->setTextColor(RED);
gfx->println("Hello World!");
Serial.println("Hello World printed!");

delay(5000); // 5 seconds
}

void loop()
{
gfx->setCursor(random(gfx->width()), random(gfx->height()));
gfx->setTextColor(random(0xffff), random(0xffff));
gfx->setTextSize(random(6) /* x scale /, random(6) / y scale /, random(2) / pixel_margin */);
gfx->println("Hello World!");

delay(1000); // 1 second
}

the output seems correct. if you uncommented the dev device in the header file, no need to touch any parameters
