ILI9341 on SPI (4-wire serial): SPI clock 30 MHz, host VSPI, BGR colour order, inversion off.

XPT2046: 2000 kHz, shares the display bus.

Check your revision. Only 264 KB of RAM - keep the LVGL draw buffer at roughly 1/10 screen.

Choose Raspberry Pi Pico + ILI9341 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 TFT_eSPI 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.

RP2040 (Pico / Pico W). PIO can drive an 8-bit parallel bus. Limited RAM - use a small partial draw buffer.

TFT_eSPI. Fastest for SPI panels on ESP32. Configured via User_Setup.h build defines.
