Instalation

Recommended method: You can download already compiled software and upload it using prepared script from release page.

Alternative method: You can download source code from release page or using git. Then compile and upload it using for example Arduino IDE. Important you need to fill your User_Setup.h file (located in Arduino/libraries/TFT_eSPI folder) with these values:

#define ILI9341_DRIVER
#define TFT_CS          5
#define TFT_DC          17
#define TFT_RST         16
#define LOAD_GLCD
#define LOAD_FONT2
#define LOAD_FONT4
#define LOAD_FONT6
#define LOAD_FONT7
#define LOAD_FONT8
#define LOAD_GFXFF
#define SMOOTH_FONT
#define SPI_FREQUENCY   10000000

ALL OTHER SETTINGS SHOULD BE REMARKED!

From v1.16 you need to update your ESP32 boards in board manager to v2.x
In case you experience QRM from the screen on 90MHz, try to lower the SPI_FREQUENCY parameter.
