Concept Overview
Ewings Framework is cover all essential things to build ESP8266 IoT applications easily. Basically it is designed on the top of arduino-esp8266 layer to make things easy to understand for developers.
Arduino has provided user-friendly libraries that use these SDK APIs at bottom. Since arduino has made its easy iot development environment impact over developers, it's easy for them to develop applications with Arduino ide.
Ewings framework sits on the top of these Arduino libraries. So the whole structure looks as shown in the above figure of Ewings Esp8266 Structure.
