ili9341 LCD to ESP32 wiring
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.
