Touch isn't working correctly with the demo


My setup:
I’m using Esp32 Devkitv1 with platformio. The Esp32devkit is connected to a raspberry pi display, the display control module is ILI9486 and the touch driver is XPT2046.

My problem:
With all the demos, Scroll and slide-on pages work perfectly, but clicking on buttons and the keyboard does not. I re-calibrated the touch’s calData but nothing changes. The only thing that works for me is the draw function on the touch calibrate code.

What MCU/Processor/Board and compiler are you using?

I’m using Esp32 devkitv1 with platformio

What do you want to achieve?

I want to fix the touch issues on my setup

What have you tried so far?

I have tried to re-calibrate the touch’s calData a few times but nothing changed

Code to reproduce

Add the relevant code snippets here.

The code block(s) should be between ```c and ``` tags:

#include <lvgl.h>
#include <TFT_eSPI.h>
#include <SPI.h>
/*If you want to use the LVGL examples,
  make sure to install the lv_examples Arduino library
  and uncomment the following line.
#include <lv_examples.h>
#include "demos/lv_demos.h"

/*Change to your screen resolution*/
static const uint16_t screenWidth = 480;
static const uint16_t screenHeight = 320;

static lv_disp_draw_buf_t draw_buf;
static lv_color_t buf[screenWidth * 10];

TFT_eSPI tft = TFT_eSPI(screenWidth, screenHeight); /* TFT instance */

#if LV_USE_LOG != 0
/* Serial debugging */
void my_print(const char *buf)

/* Display flushing */
void my_disp_flush(lv_disp_drv_t *disp, const lv_area_t *area, lv_color_t *color_p)
  uint32_t w = (area->x2 - area->x1 + 1);
  uint32_t h = (area->y2 - area->y1 + 1);

  tft.setAddrWindow(area->x1, area->y1, w, h);
  tft.pushColors((uint16_t *)&color_p->full, w * h, true);

  String LVGL_Arduino = "Hello Arduino! ";
  LVGL_Arduino += String('V') + lv_version_major() + "." + lv_version_minor() + "." + lv_version_patch();

  Serial.println("I am LVGL_Arduino");

    lv_label_set_text( label, LVGL_Arduino.c_str() );
    lv_obj_align( label, LV_ALIGN_CENTER, 0, 0 );
  /* Try an example from the lv_examples Arduino library
     make sure to include it as written above.

  // uncomment one of these demos
  // lv_demo_widgets(); // OK
  // lv_demo_benchmark(); // OK
  lv_demo_keypad_encoder(); // works, but I haven't an encoder
                            // lv_demo_music(); // NOK
                            // lv_demo_printer();
                            // lv_demo_stress(); // seems to be OK
  Serial.println("Setup done");

void loop()
  lv_timer_handler(); /* let the GUI do its work */
