W5x00 ethernet library for STM32F103 micro-controllers
----
That library has been ported from the **WIZnet WIZ_Ethernet_Library**, to STM32F103 microcontrollers.
The library supports **W5100** and **W5500** Ethernet controllers. The source code has been modified to support the **W5200** too, but has not been tested (yet) on a real W5200 controller.
Ported to STM32F103 on 23 Aug 2015 by **Vassilis Serasidis**
Library installation
----
### *Install the library globally* ###
* Unzip the file **Ethernet_STM-master.zip** into your Arduino IDE directory
> arduino\libraries
and rename the folder **Ethernet_STM-master** to **Ethernet_STM**
In this case the library can be used from the 8-bit and 32-bit Arduino boards (UNO, Nano, DUE etc) and from STM32F1 microcontroller series (for example STM32F103).
#### *Install the library for using it only with STM32F1 series* ###
* Unzip the file **Ethernet_STM-master.zip** into your Arduino IDE directory
> ...arduino\hardware\Arduino_STM32\STM32F1\libraries
and rename the folder **Ethernet_STM-master** to **Ethernet_STM**
Selecting the Ethernet type controller (W5100, W5200 or W5500)
----
For selecting among those tree chips edit the file:
`Ethernet_STM\src\utility\w5100.h`
and comment-out only the line with the chip you want to use.
By default the **W5500** ethernet controller is selected.
```
//#define W5100_ETHERNET_SHIELD // Arduino Ethenret Shield and Compatibles ...
//#define W5200_ETHERNET_SHIELD // WIZ820io, W5200 Ethernet Shield
#define W5500_ETHERNET_SHIELD // WIZ550io, ioShield series of WIZnet
```
If you edit the **w5100.h** file, save it and re-compile your sketch.
Selecting W5500 Sockets number and RAM buffer amount
----
For selecting the Sockets number (1-8) and the RAM buffer amount (1-16 kBytes) for each Socket, edit the file:
`Ethernet_STM\src\utility\w5500.h`
and change the values you want.
```
Total RAM buffer is 16 kBytes for Transmitter and 16 kBytes for receiver for 1 Socket.
The Total W5500 RAM buffer is 32 kBytes (16 + 16).
If you use more Sockets then the RAM buffer must be split.
For example: if you use 2 Sockets then all socket must use upto 16 kBytes in total RAM.
So, we have:
#define MAX_SOCK_NUM 2 // Select two Sockets.
#define RXBUF_SIZE 8 // The Receiver buffer size will be 8 kBytes
#define TXBUF_SIZE 8 // The Transmitter buffer size will be 8 kBytes
In total we use (2 Sockets)*(8 kBytes) for transmitter + (2 Sockets)*(8 kBytes) for receiver = 32 kBytes.
I would prefer to use only 1 Socket with 16 kBytes RAM buffer for transmitter and 16 kByte for receiver buffer.
#define MAX_SOCK_NUM 1 // Select only one Socket
#define RXBUF_SIZE 16 // Select 16 kBytes Receiver RAM buffer
#define TXBUF_SIZE 16 // Select 16 kBytes Transmitter RAM buffer
```
Default settings:
```
#define MAX_SOCK_NUM 8 // Select the number of Sockets (1-8)
#define RXBUF_SIZE 2 // Select the Receiver buffer size (1 - 16 kBytes)
#define TXBUF_SIZE 2 // Select the Transmitter buffer size (1 - 16 kBytes)
```
If you edit the **w5500.h** file, save it and re-compile your sketch.
Using the Ethernet_STM library
----
1. Choose the desired ethernet chip you want to use (W5100, W5200 or W5500) from the w5100.h file
2. include this library in your sketch
`#include <Ethernet_STM.h>`
All functions / commands have the same syntax with the stock Arduino Ethernet library.
PIN Connections

Twitter Serial GW
Sample : Serial port => Twitter gateway
Run this program on Arduino and connect via some Serial port terminal software.
Type a message and hit enter key, and it will be posted to Twitter.
Arduino IDE Serial Monitor is not usable because it doesn't seem able to send Enter key code.
Notice
-The library uses this site as a proxy server for OAuth stuff. Your tweet may not be applied during maintenance of this site.
-Please avoid sending more than 1 request per minute not to overload the server.
-Twitter seems to reject repeated tweets with the same contenet (returns error 403).

Cosm sensor client
This sketch connects an analog sensor to Cosm (http://xively.com)
using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
the Adafruit Ethernet shield, either one will work, as long as it's got
a Wiznet Ethernet module on board.
This example has been updated to use version 2.0 of the cosm.com API.
To make it work, create a feed with a datastream, and give it the ID
sensor1. Or change the code below to match your feed.
Circuit:
* Analog sensor attached to analog in 0
* Ethernet shield attached to pins 10, 11, 12, 13

* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being

/** Total RAM buffer is 16 kBytes for Transmitter and 16 kBytes for receiver for 1 Socket.
* The Total W5500 RAM buffer is 32 kBytes (16 + 16).
* If you use more Sockets then the RAM buffer must be split.
* For example: if you use 2 Sockets then all socket must use upto 16 kBytes in total RAM.
* So, we have:
*
* #define MAX_SOCK_NUM 2 // Select two Sockets.
* #define RXBUF_SIZE 8 // The Receiver buffer size will be 8 kBytes
* #define TXBUF_SIZE 8 // The Transmitter buffer size will be 8 kBytes
*
* In total we use (2 Sockets)*(8 kBytes) for transmitter + (2 Sockets)*(8 kBytes) for receiver = 32 kBytes.
*
* I would prefer to use only 1 Socket with 16 kBytes RAM buffer for transmitter and 16 kByte for receiver buffer.
*
* #define MAX_SOCK_NUM 1 // Select only one Socket
* #define RXBUF_SIZE 16 // Select 16 kBytes Receiver RAM buffer
* #define TXBUF_SIZE 16 // Select 16 kBytes Transmitter RAM buffer
