<a><h2>Introduction</a></h2>
|
||
|
|
<p>This example implements a basic Web server and a basic TFTP server.
|
||
|
|
It is running on top of the <a href="http://www.sics.se/~adam/lwip"<font color="red"></font>lwIP TCP/IP stack</a> and the AVR32 UC3 <a href="http://freertos.org"<font color="red"></font>freeRTOS.org</a> port.</p>
|
||
|
|
<p>This example thus contains a port of the <a href="http://www.sics.se/~adam/lwip"<font color="red"></font>lwIP TCP/IP stack</a>. This port is using both the AVR32 UC3 <a href="http://freertos.org"<font color="red"></font>freeRTOS.org</a> port and the AVR32 UC3A MACB interface for the Ethernet access.</p>

<a><h2>lwIP TCP/IP stack</a></h2>
|
||
|
|
<p>lwIP is an implementation of the TCP/IP protocol suite. The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full scale TCP.</p>
|

<DT><B><u>lwIP features</u>:</B>
|

<a><h2>The Basic Web server</a></h2>
|
||
|
|
<p>Implements a simplistic WEB server.</p>
|
||
|
|
<B><u>Demo description</u>:</B> Every time a connection is made and data is received, a dynamic page that shows the current FreeRTOS.org kernel statistics is generated and returned. The connection is then closed.</p>
|
||
|
|
<B><u>Note</u>:</B> The WEB server is reachable at the IP address 192.168.0.2.

<a><h2>The Basic TFTP server</a></h2>
|
||
|
|
<p>Implements a simplistic TFTP server.</p>
|
||
|
|
<DT><B><u>Demo description</u>:</B>
|
||
|
|
<DD><p class="whs3"><li>To put a file onto the TFTP server (Supported file size < 2048 bytes), on a PC command line type <i><b>tftp 192.168.0.2 PUT "a_file"</i></b>: this will copy <i>a_file</i> from your hard drive to a RAM buffer of the demo.</p></li>
|
||
|
|
<DD><p class="whs3"><li>To get a file from the TFTP server, on a PC command line type <i><b>tftp 192.168.0.2 GET "a_file"</i></b>: this will copy <i>a_file</i> from the RAM buffer of the application to the PC's hard drive.</p></li>
|
||
|
|
<B><u>Note 1</u>:</B> only one file at a time is supported on this TFTP server. This is because the TFTP server being a simplistic example, it does not use a file system to store files but a predefined RAM area of 2048 Bytes.
|
||
|
|
<p><B><u>Note 2</u>:</B> The TFTP server is reachable at the IP address 192.168.0.2.</p>
