Connect as DOIT ESP32 DEVKIT V1

=======

To connect ST7789 w/o CS pin need to modify TFT_eSPI lib:

In ../libraries/TFT_eSPI/User_Setups/Setup24_ST7789.h:

uncomment this:

// Generic ESP32 setup
#define TFT_MISO -1 // Not connected
#define TFT_MOSI 23 // SDA pin
#define TFT_SCLK 18 // SCK pin
#define TFT_CS -1 // Not connected
#define TFT_DC 2 // DC pin
#define TFT_RST 4 // RES pin

comment this:

// For NodeMCU - use pin numbers in the form PIN_Dx where Dx is the NodeMCU pin
// designation
// #define TFT_CS   -1      // Define as not used
// #define TFT_DC   PIN_D1  // Data Command control pin
// #define TFT_RST  PIN_D4  // TFT reset pin (could connect to NodeMCU RST, see
// next line) #define TFT_RST  -1    // TFT reset pin connect to NodeMCU RST,
// must also then add 10K pull down to TFT SCK

In ../libraries/TFT_eSPI/User_Setup_Select.h:

Replace

// #include <User_Setup.h>           // Default setup is root library folder

with

#include <User_Setups/Setup24_ST7789.h> // Setup file for DSTIKE/ESP32/ESP8266 configured for ST7789 240 x 240
