assert fails for nvs_get_blob() in lvgl_wificonfig example about esp-iot-solution

[timredfern]

I tried the other lvgl examples.

I see the NVS read assert fail and halt with lvgl_example also.

lvgl_coffee doesn't build:

esp-iot-solution/examples/hmi/lvgl_coffee/main/app_main.cpp:362:64: error: invalid conversion from 'void ()(lv_obj_t, uint16_t) {aka void ()(_lv_obj_t, short unsigned int)}' to 'lv_tabview_action_t {aka unsigned char ()(_lv_obj_t, short unsigned int)}' [-fpermissive]

the Makefile in lvgl_thermostat is broken but it builds with the Makefile from lvgl_example.

When it runs it also halts with the assert failure.

Thanks，I‘ll fix it as soon as possible.

This error indicates that there is no calibration data in the flash. Please recalibrate on the screen.

esp-iot-solution/examples/hmi/lvgl_coffee/main/app_main.cpp:362:64: error: invalid conversion from 'void ()(lv_obj_t, uint16_t) {aka void ()(_lv_obj_t, short unsigned int)}' to 'lv_tabview_action_t {aka unsigned char ()(_lv_obj_t, short unsigned int)}' [-fpermissive]

Please modify the following::

static lv_res_t tabview_load_action(lv_obj_t *tabview, uint16_t tab_action_id)
{
    tab_id = tab_action_id;
    return LV_RES_OK;
}

Thanks Yuan, I was having the same issue, the above edit fixed it.
