## Ethernet Library for Arduino
4+
5+
With an STM32 board with Ethernet compatibility, this library allows a STM32
6+
board (NUCLEO, DISCOVERY, ...) to connect to the internet.
7+
8+
For more information about this library please visit us at
9+
http://www.arduino.cc/en/Reference/Ethernet
10+
11+
## Note
12+
13+
The library is based on LwIP, a Lightweight TCP/IP stack.
14+
http://git.savannah.gnu.org/cgit/lwip.git
15+
The LwIP has been ported as Arduino library. The STM32Ethernet library depends
16+
on it.
17+
18+
EthernetClass::maintain() in no more required to renew IP address from DHCP.
19+
It is done automatically by the LwIP stack in a background task.
20+
21+
An Idle task is required by the LwIP stack to handle timer and data reception.
22+
This idle task is called inside the main loop in background by the function
23+
stm32_eth_scheduler(). Be careful to not lock the system inside the function
24+
loop() where LwIP could never be updated. Call EthernetUDP::parsePacket() or
25+
EthernetClient::available() performs an update of the LwIP stack.
26+

Advanced Chat Server
3+
4+
A more advanced server that distributes any incoming messages
5+
to all connected clients but the client the message comes from.
6+
To use, telnet to your device's IP address and type.
7+
You can see the client's input in the serial monitor as well.
