Dear @MilanTandel
Here you can find the example for keyboard interfacing is named host_hid_mouse_keyboard_freertos inside the USB_examples section.
To use it together with your GUIguider design you need to merge both projects in MCUXpresso.
Please check the following link, Getting Started with GUI Guider | NXP Semiconductors, here describes how to add generated code from GUI Guider to an existing MCUXpresso project with LVGL.
After joint both projects you can use the file events_init.c to connect your widgets with the keyboard input, using for example lv_label_set_text():
The following function uses the value received from slider_rx_gain that is in Settings_screen to change the value of two labels.
static void Settings_screen_slider_rx_gain_event_handler(lv_event_t *e)
{
lv_event_code_t code = lv_event_get_code(e);
switch (code)
{
case LV_EVENT_VALUE_CHANGED:
{
static uint8_t rxgain_buf[17];
uint8_t slider_rx_gain_value = lv_slider_get_value(guider_ui.Settings_screen_slider_rx_gain);
double product = (slider_rx_gain_value*1.2)-60;
snprintf(rxgain_buf, 17, "Rx Gain %.1fdB",product);
lv_label_set_text(guider_ui.Settings_screen_label_rx_gain_value, rxgain_buf);
lv_label_set_text(guider_ui.Main_screen_label_rx_gain, rxgain_buf);
}
break;
default:
break;
}
}

I hope this information help you.
Kind Regards!
