Paul Staron / Mbed 2 deprecated ESP8266-WEB-Mbed-Controller

Fork of Farrukh's webserver. Tested on LPC1768 and STM32f401 but should work on almost any platform.

Dependencies:   mbed

New version that has been tested on LPC1768 and STM32F401 Based on Farrukh's idea here: https://os.mbed.com/users/programmer5/code/STM32-ESP8266-WEBSERVER/

Enter your Wi-Fi SSID and PASSWORD and edit the espbaud to suit your ESP8266, Works fast and stable at 460800.

Use configuration program to reset and set up the ESP8266 if needed:

Limitations are no HTTPS.
