NodeMCU (ESP8266) SDK and Libraries
====================================================================================================

All files under this directory and its subdirectories are copied from the GIT repository of Arduino
core for ESP8266 WiFi chip (https://github.com/esp8266/Arduino). Some unnecessary files from the
repository are not included to reduce the number of files.

These files are included in the eCxx distribution package for convenience. They should be compilable
using various toolkit versions that come with the ESP8266 Community package which can be downloaded
and installed using Arduino Board Manager (it is an add-on package for Arduino IDE).

All source code files, libraries, firmware, binaries, and other files under this directory and its
subdirectories that are *linked* with the eCxx library are licensed under their own licensing terms
and conditions that are compatible with eCxx licenses.
