Quick start (ESP32 + TFT_eSPI)

1. Install Arduino IDE and the ESP32 board package (Espressif).
2. Library Manager → install TFT_eSPI by Bodmer.
3. Copy this repo’s setup file into the library (see User guide).
4. Select that setup in User_Setup_Select.h.
5. Wire the module, open examples/ColorTest, Upload.

Recommended ESP32 wiring

Module pin	ESP32 GPIO
GND	GND
3V3	3.3 V
CS	2
RST	13
SCK	18
MOSI	23
D/C	12

These GPIOs match TFT_eSPI_Setup/Setup_UGE_ST7789_ESP32.h.

Why configure User_Setup_Select.h?

TFT_eSPI’s built-in examples only include <TFT_eSPI.h>. They read pins from the library setup.

One library setup means:

• The colour test works
• Every TFT_eSPI example works with the same wiring
• Your own sketches need only #include <TFT_eSPI.h>
