  Hello @mathi_kbr ,
  https://docs.lvgl.io/master/details/widgets/keyboard.html
  You can connect a keyboard to an lv_textarea (text area) component and then retrieve the text content from this lv_textarea.
  `
  // Create a text area (textarea)
  lv_obj_t *textarea = lv_textarea_create(lv_scr_act());
  lv_textarea_set_one_line(textarea, true); // Set to single-line input (if needed)
  lv_obj_set_width(textarea, 200); // Set the width of the text area

  // Create a keyboard
  lv_obj_t *keyboard = lv_keyboard_create(lv_scr_act());
  lv_keyboard_set_mode(keyboard, LV_KEYBOARD_MODE_TEXT_LOWER); // Set to lowercase mode (optional)
  lv_keyboard_set_textarea(keyboard, textarea); // Connect the keyboard and text area

  // Retrieve the input content
  const char *input_text = lv_textarea_get_text(textarea);
  printf("Input Text: %s\n", input_text); // Print or process the input content
  `
  Explanation:
  Create a Text Area: Use lv_textarea_create() to create a text area for keyboard input.
  Create a Keyboard and Set Mode: Use lv_keyboard_create() to create a keyboard, which can be set to lowercase mode, etc.
  Connect the Keyboard and Text Area: Use lv_keyboard_set_textarea() to associate the keyboard with the textarea. This way, the keyboard input will display in the textarea.
  Retrieve Input Content: When you need to get the input content, call lv_textarea_get_text(textarea) to obtain the current input text.
  In this way, you can easily retrieve the user's keyboard input for assignment or further processing.
