## I'm testing connecting the ESP32 to the 2.8" ili9341 TFT
## SPI display (320x240) which contains a xpt2046 touchscreen
## for use within ESPHome and Home Assistant.
## At this time, I'm not tring to support the SD card.

##
## 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.
##
## LCD to ESP32 (30 pin or d1 mini) wiring:
## * SCK/CLK to 18
## * MISO/DO/SDO to 19
## * MOSI/DIN/SDI to 23
## * DISP_CS to 33
## * DISP_LED to 17
## * TOUCH_CS to 32
## * DISP_DC to 5
## * DISP_RESET to 16
## * TOUCH_IRQ 21
## * VCC to 3V3
## * GND to GND
