Check your revision. AMOLED brightness is set by a controller command, not a backlight GPIO.

Choose LilyGO T-Display-S3 AMOLED on the Hardware tab (or use the button above) and every pin on this page is filled in. The export writes the sketch, lcd_pins.h, the GFX Library for Arduino configuration, lv_conf.h and platformio.ini - a project that builds for this board as it comes.
The CST226SE is capacitive and needs no calibration. The firmware resets it and checks it answers on every boot.
With PSRAM the LVGL memory pool can live there, leaving internal RAM for everything else.
Screens are designed for 240 x 536 px in either orientation, with LVGL 9 or LVGL 8.

RM67162. LilyGO T-Display-S3 AMOLED.

CST226SE. Used on LilyGO T-Display AMOLED and several round AMOLED boards.

ESP32-S3. The only common Arduino target with a hardware RGB565 LCD peripheral. PSRAM is effectively required for RGB panels.

GFX Library for Arduino. Moshi Liu's library. Best QSPI/AMOLED and RGB coverage. Configured in code.
