TFT Display Wiring: TFT_VCC → ESP32 VIN / 3V3 TFT_GND → ESP32 GND TFT_CS → ESP32 D15 / GPIO 15 (Chip Select) TFT_RST → ESP32 D4 / GPIO 4 (Reset Pin) TFT_DC → ESP32 D2 / GPIO 2 (Data/Command) TFT_MOSI → ESP32 D23 / GPIO 23 (MOSI) TFT_SCK → ESP32 D18 / GPIO 18 (Clock) TFT_LED → ESP32 3V3 (LED Backlight) TFT_MISO → ESP32 D19 / GPIO 19 (MISO)

Touchscreen Wiring (XPT2046): T_CLK → ESP32 D18 / GPIO 18 (Clock, shared with TFT) T_CS → ESP32 D21 / GPIO 21 (Touchscreen Chip Select) T_DIN → ESP32 D23 / GPIO 23 (Data Input, shared with TFT MOSI) T_DO → ESP32 D19 / GPIO 19 (Data Output, shared with TFT MISO) T_IRQ → Optional: Connect to an available GPIO (e.g., GPIO 22) or leave unconnected.

SD Card Wiring: SD_SCK → ESP32 D18 / GPIO 18 (Shared with TFT) SD_MISO → ESP32 D19 / GPIO 19 (Shared with TFT) SD_MOSI → ESP32 D23 / GPIO 23 (Shared with TFT) SD_CS → ESP32 D5 / GPIO 5 (You can choose a different GPIO if needed)
