Ethernet drivers for lwIP on esp8266

This library brings full ethernet (RJ45 cables) connectivity into an already existing lwIP stack, such as the one in esp8266.

Every network services should work

  • dhcp (client only for now)
  • dns
  • http(s) clients+servers
  • mqtt
  • ... your already working network services
  • no need for separate UDP/TCP api (like uIP or others, lwIP is already here)

W5100, W5500 and enc28j60 drivers are slightly modified versions of

https://github.com/njh/W5500MacRaw

https://github.com/njh/EtherSia (enc28j60)

How to use

Example soon (watch the few opened issues)

As for now, the network interface is working as DHCP client only

What's next

  • allow dhcp server
  • provide better network helpers (like arduino's WiFi.status())

Notes (esp8266 and w5500, w5100?)

  • the TCP/IP part of W5x00 chips is not used, the ethernet interface only is.
  • Do not directly connect SPI CS(ChipSelect) to esp8266'SS(SlaveSelect) (GPIO15), use another pin (hacks using a transistor exist for using this pin).

Roadmap

  • integration in esp8266 arduino core (this repository will be obsoleted)
  • dhcp server / driver for enc28j60
  • NAT (esp8266/arduino core (lwip2)) (done)
