Roy van Dam / NetworkAPI

A new object oriented network api that can be used to replace the one provided by the EthernetInterface library.

Dependents:   NetRelais TCP_Client_Example TCP_Server_Example UDP_Server_Example ... more

Object oriented network interface for the mbed platform

Currently implemented:

  • Address
  • Endpoint
  • UDP Socket
  • TCP Socket
  • Databuffer
  • Select API

It depends on the EthernetInterface for the lwip network stack.

Please do not hesitate to contact me with any remarks, improvements or questions.

The API is also available for unix at GitHub: LibNosa
