XPT2046: 2000 kHz, its own SPI bus.

Check your revision. These are the standard FSMC bank-1 pins. A16 (PD11) is wired to the RS/DC line.

Choose STM32F407 + ILI9341 16-bit FSMC 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 LovyanGFX configuration, lv_conf.h and platformio.ini - a project that builds for this board as it comes.
The XPT2046 is resistive and reads through its library; set its raw range on the Touch tab.
The backlight is dimmable: give a slider or a button a Set backlight action.
Screens are designed for 240 x 320 px in either orientation, with LVGL 9 or LVGL 8.

ILI9341. The most common hobby TFT. 2.2"-2.8" modules, usually with an XPT2046 resistive panel.

XPT2046. The classic 4-wire resistive controller. Needs calibration. Can share the display SPI bus with its own CS.

STM32F4 (F401 / F407 / F411). Use the STM32duino core. FSMC gives a fast parallel bus on F407 and up.

LovyanGFX. Widest panel and bus coverage, DMA on ESP32. Configured with a C++ config class.
