Objective was to write ESP8266 interfacing code that should be able to work with any microcontroller and any C/C++ compiler. Speed was of prime importance, I've tested several mbed examples for ESP8266, all work too slow, is hard to run real server with available libraries, so I've written my own interrupt based functions. ESP8266 webserver using AT commands, can work with any mbed platform, tested on STM32F407 and LPC1768. Only need to update pin configuration to make it work for respective board. Also tested on PIC18 using mikroC PRO for PIC. Here are some videos that show how this project works
