| |
| <h2>Introduction</h2> |
| <p>This example implements a basic Web server and a basic TFTP server. |
| It is running on top of the <a href="http://savannah.nongnu.org/projects/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://savannah.nongnu.org/projects/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> |
| |
| <p> </p> |
| |
| <h2>lwIP TCP/IP stack</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> |
| <DD><p class="whs3"><li>IP (Internet Protocol) including packet forwarding over multiple network interfaces</p></li> |
| <DD><p class="whs3"><li>ICMP (Internet Control Message Protocol) for network maintenance and debugging</p></li> |
| <DD><p class="whs3"><li>UDP (User Datagram Protocol) including experimental UDP-lite extensions</p></li> |
| <DD><p class="whs3"><li>TCP (Transmission Control Protocol) with congestion control, RTT estimation and fast recovery/fast retransmit</p></li> |
| <DD><p class="whs3"><li>Specialized raw API for enhanced performance</p></li> |
| <DD><p class="whs3"><li>Optional Berkeley-alike socket API</p></li> |
| <DD><p class="whs3"><li>DHCP (Dynamic Host Configuration Protocol)</p></li> |
| <DD><p class="whs3"><li>PPP (Point-to-Point Protocol)</p></li> |
| <DD><p class="whs3"><li>ARP (Address Resolution Protocol) for Ethernet</p></li> |
| <p>lwIP is freely available (under a BSD-style license) in C source code format and can be downloaded from the <a href="http://savannah.nongnu.org/projects/lwip"<font color="red"></font>development homepage</a>.</p> |

| |
| <h2>The Basic Web server</h2> |
| <p>Implements a simplistic WEB server. To use this demo part, define HTTP_USED to 1, else define to 0. (default is 1)</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. |
| |
| <p> </p> |
| |
| <h2>The Basic TFTP server</h2> |
| <p>Implements a simplistic TFTP server. To use this demo part, define TFTP_USED to 1, else define to 0. (default is 1)</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> |
| |
| <p> </p> |
| |
| <h2>The Basic SMTP client</h2> |
| <p>Implements a simplistic SMTP client. To use this demo part, define SMTP_USED to 1, else define to 0. (default is 0)</p> |
| <DT><B><u>Demo description</u>:</B> |
| <DD><p class="whs3"><li>Prior to compile and run the SMTP client, you will have to configure the connection settings : |
| <DD><DD><li>Server address : default is <i>192.168.0.1</i>.</li> |
| <DD><DD><li>Server name : used in the EHLO field, default is <i>smtp.domain.com</i>.</li> |
| <DD><DD><li>Mail sender : used in the mailfrom field, default is <i>sender@domain.com</i>.</li> |
| <DD><DD><li>Mail recipient : used in the mailto field, default is <i>receiver@domain.com</i>.</li> |
| <DD><DD><li>Mail content : default is <i>Subject: *** SPAM ***\r\nFROM: \"Your Name here\" <sender@domain.com>\r\nTO: \"Your Contact here\" <receiver@domain.com>\r\n\r\nSay what you want here</i>.</li> |
| </p></li> |
| <DD><p class="whs3"><li>Once all fields are configured, remove the <i>#error</i> lines to allow compilation.</p></li> |
| <DD><p class="whs3"><li>Run the software and press Push Button 0 to send an email.</p></li> |
| |
| <p> </p> |
| |
| <h2>Device Info</h2> |
| All AVR32 UC3A devices with a MACB module can be used. This example has been tested with the following setup(s): |
| <DD><p class="whs3"><li type="disc">AT32UC3A0512 on the EVK1100 evaluation kit.</li></p> |
