Compatibility with arduino uIP

[DrBomb]

Arduino uIP is a drop-in library for boards based on the ENC28J60. It has the same API as the ethernet.h.
Ethernet example worked flawlessly after adding. Will continue testing.

Might have to note that it's a bit unstable, only aREST needs to be included because any other library makes the GET requests fail silently

Hi DrBomb, can you explain more what are the enhancements that the uIP library brings ?

Dear sir,

provide me arduino code to control a robot using esp8266 as an access point

I would suggest extending the existing preprocessor macro instead of just duplicating code:

576c576
< #elif defined(ethernet_h_)
---
> #elif defined(ethernet_h_) || defined(UIPETHERNET_H)
1554c1554
<   #if defined(ADAFRUIT_CC3000_H) || defined(ESP8266) || defined(ethernet_h_) || defined(WiFi_h)
---
>   #if defined(ADAFRUIT_CC3000_H) || defined(ESP8266) || defined(ethernet_h_) || defined(UIPETHERNET_H) || defined(WiFi_h)
