code adaptation

Hi, I'm trying to redo your code for ILI9488 and the TFT_eSPI library, but I don't understand why it won't start, tell me what the problem is

/*______Import Libraries_______*/
#include <Arduino.h>
#include <SPI.h>
#include "TFT_eSPI.h"
//#include "usergraphics.h"
/*______End of Libraries_______*/

/*____Calibrate Touchscreen_____*/
#define MINPRESSURE 10      // minimum required force for touch event
#define TS_MINX 370
#define TS_MINY 470
#define TS_MAXX 3700
#define TS_MAXY 3600
/*______End of Calibration______*/

/*___Keylock spezific definitions___*/
#define codenum 42    // 42 is the answer for everything, but you can change this to any number between 0 and 999999

/*___End of Keylock spezific definitions___*/

Did you've changed eTFT User_setup.h file to the right ports for ILI9488. ???

yes

[HWHardsoft]

Including ESP32 port section?

yes

I talk about Section 2 in this file.....

`// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP32 SETUP ######

// For ESP32 Dev board (only tested with ILI9341 display) // The hardware SPI can be mapped to any pins

define TFT_SCLK 9

define TFT_CS A3 // Chip select control pin

define TFT_DC 0 // Data Command control pin

thank you for the answer, unfortunately it doesn't work, I registered all the pins correctly, there was another error, the screen lights up and immediately goes out, after a couple of hours I can send a video so that it is clearly visible
