Hi there,

I see the library has support for ESP32-S3-BOX, however this is no longer in production and has been superseded by the ESP32-BOX-S3-3 (an overly long model number, note the "-3" suffix).

Please see here https://github.com/espressif/esp-box/tree/master

The device currently supported by your library has, I think, the same SPI pinout, but LCD backlight is on GPIO47 vs GPIO45 for the S3-BOX, hence selecting AUTODETECT or specifying

#define LGFX_ESP32_S3_BOX                  // Espressif ESP32-S3-BOX

Compiles ok, but nothing is displayed on the LCD.

The pinout is on the schematic here https://github.com/espressif/esp-box/blob/master/hardware/SCH_ESP32-S3-BOX-3_V1.0/SCH_ESP32-S3-BOX-3-MB_V1.1_20230808.pdf

The LCD backlight control is on GPIO47.

Thanks for your assistance.
