T-Display

The LilyGO T-Display board is not shown in the boards list. It is an ESP32 Dev Module.

The T-Display has i2c on pins 21 and 22, so in the Arduino IDE you need to initialize the Wire library with "Wire.begin(21,22);".

To use the TFT_eSPI library needs a little config for the T-Display. The User_Setup.h need to be edited as below.

#define ST7789_DRIVER

// IPS 1.14 in T-Display
#define TFT_WIDTH 135
#define TFT_HEIGHT 240


#define TFT_MOSI 19
#define TFT_SCLK 18
#define TFT_CS 5
#define TFT_DC 16
#define TFT_RST 23
#define TFT_BL 4
