ili9341 LCD to ESP32 wiring
Writeup and wiring from Kevin Dorff, library author and github repository:

The SPI pins, MOSI, MISO, and SCK, are shared between the display and the touchscreen (and SD card reader). TOUCH_IRQ is optional. If you don't wire it, make sure you comment out touchscreen.interrupt_pin.
The SD card pins are not connected.
These may not be optimum wiring, but I've tested them.
This is the ILI9341 connector pinout:
| Pin | Function |
|---|---|
| 1 | Vcc |
| 2 | Gnd |
| 3 | CS |
| 4 | Reset |
| 5 | Dc |
| 6 | MOSI (LCD) |
| 7 | SCK (LCD) |
| 8 | LED |
| 9 | MISO (LCD) |
| 10 | T_Clk |
| 11 | T_CS |
| 12 | T_DIN |
| 13 | T_DO |
| 14 | T_IRQ |
LCD to ESP32 (30 pin or d1 mini) wiring:
| Display | ESP32 |
|---|---|
| SCK/CLK | 18 |
| MISO/DO/SDO | 19 |
| MOSI/DIN/SDI | 23 |
| DISP_CS | 33 |
| DISP_LED | 17 |
| TOUCH_CS | 32 |
| DISP_DC | 5 |
| DISP_RESET | 16 |
| TOUCH_IRQ | 21 |
| VCC | 3V3 |
| GND | GND |
