Helpers
=======

esphomelib uses a bunch of helpers to make the library easier to use.

API Reference

.. doxygenvariable:: global_preferences

esphal.h
********

This header should be used whenever you want to access some `digitalRead`, `digitalWrite`, ... methods.

ESPOneWire
**********

esphomelib has its own implementation of OneWire, because the implementation in the Arduino libraries
seems to have lots of timing issues with the ESP8266/ESP32. That's why ESPOneWire was created.
