Library for ENC28J60 Ethernet modules.

/media/uploads/hudakz/enc28j60_module01.jpg

Ported to mbed from Norbert Truchsess's UIPEthernet library for Arduino. Thank you Norbert!

  • Full support for persistent (streaming) TCP/IP and UDP connections Client and Server each, ARP, ICMP, DHCP and DNS.
  • Works with both Mbed OS 2 and Mbed OS 5.

Usage:

  • Import the library into your project.
  • Add #include "UipEthernet.h" to main.cpp
  • Create one instance of the UipEthernet class initialized with the MAC address you'd like to use and SPI pins of the connected Mbed board.

Example programs:

Import programWebSwitch_ENC28J60

HTTP Server serving a simple webpage which enables to remotely turn a digital output on/off. Compile, download, run and type 'IP_address/secret/' (don't forget the last '/') into your web browser and hit ENTER.

Import programHTTPServer_Echo_ENC28J60

A simple HTTP server echoing received requests. Ethernet connection is over an ENC28J60 board. Usage: Type the server's IP address into you web browser and hit <ENTER>.
