/**
* TestEspApi by Max Vilimpoc
* This code is released to the public domain.
*
* Test out the Expressif ESP8266 Non-OS API, exhaustively trying out
* as many of the built-in functions as possible.
*
* Some of the code is based on examples in:
* "20A-ESP8266__RTOS_SDK__Programming Guide__EN_v1.3.0.pdf"
