Library for ENC28J60 Ethernet modules.
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"
tomain.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>.
Import programTcpServer_ENC28J60
Simple TCP/IP Server using the UIPEthernet library for ENC28J60 Ethernet boards.
Import programTcpClient_ENC28J60
Simple TCP/IP Client using the UIPEthernet library for ENC28J60 Ethernet boards.
Import programUdpServer_ENC28J60
Simple UDP Server using the UIPEthernet library for ENC28J60 Ethernet boards.
Import programUdpClient_ENC28J60
Simple UDP Client using the UIPEthernet library for ENC28J60 Ethernet boards.
Import programMQTT_Hello_ENC28J60
MQTT Client example program. Ethernet connection is via an ENC28J60 module.
