Have a working lvgl 8.3.3, don't know how to update touch feature to version 9.2 of lvgl

Hello, I have a working example from a vendor to my ESP32-4827S043C, it works just for lvgl 8.3.3 with lv_conf.h and touch.h set to my board and display. I had installed succesfuly the lv_demo_widgets() example in it. But I need to update the example to lvgl 9.2 to use new features such as scale in my code that I had for the lvgl 9.2. My first necessity is to updade the touch.

Thanks for giving a look and any tip on where to get started is appreciated.

ESP32-4827S043C

Updade the touch related code to port lvgl from version 8.3.3 to 9.2 .

So far I tried to just update the lvgl arduino ide library to 9.2 and follow the corrections that the compiler gives. But it ended up in the end just having gcc compiler errors such as no typedef opcode.

With just the original code for 8.3.3 and with lvgl 9.2 library installed i have these problems:

The compiler gives error on

static lv_disp_draw_buf_t draw_buf;
static lv_disp_drv_t disp_drv;
void my_disp_flush(lv_disp_drv_t *disp, const lv_area_t *area, lv_color_t *color_p)
void my_touchpad_read(lv_indev_drv_t *indev_driver, lv_indev_data_t *data)
    lv_disp_draw_buf_init(&draw_buf, disp_draw_buf, NULL, screenWidth * screenHeight/4);

    /* Initialize the display */
    lv_disp_drv_init(&disp_drv);
    /* Change the following line to your display resolution */

    disp_drv.flush_cb = my_disp_flush;

    lv_disp_drv_register(&disp_drv);

    /* Initialize the (dummy) input device driver */
    static lv_indev_drv_t indev_drv;
    lv_indev_drv_init(&indev_drv);
  
    indev_drv.read_cb = my_touchpad_read;
    lv_indev_drv_register(&indev_drv);

Here is the code for the LvglWidgets.ino that i need to update
