nfc_attendance_system_esp32's Issues

When I Learning your project, I have some questions

In your main/src/core/os.c, I find some code:

    ESP_ERROR_CHECK(esp_event_loop_create_default());

    ESP_ERROR_CHECK(esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &wifi_event_handler, NULL));
    ESP_ERROR_CHECK(esp_event_handler_register(IP_EVENT, ESP_EVENT_ANY_ID, &ip_event_handler, NULL));
    ESP_ERROR_CHECK(esp_event_handler_register(SC_EVENT, ESP_EVENT_ANY_ID, &sc_event_handler, NULL));

Those mean create a default event loop, and put any event to this loop.

I want to know WIFI_EVENT, IP_EVENT, SC_EVENT mean what, I can't check with IDE "Go to definition" or "Go to declaration"

I google of this, I see in this website he also set same name to this position.

I want to know want it is?

The manual is this:

when I try to go to definition:

And when I learn freertos, in xTaskCreate also set pcName as string. Does those is one type thing?

Thank you!
