Description of example project

||
|
|
==============================
|
||
|
|
|
||
|
|
HTTPSERVER
|
||
|
|
|
||
|
|
This is a demonstration of how to make the most basic kind
|
||
|
|
of server using lWIP.
|
||
|
|
|
||
|
|
* httpd.c - uses,
|
||
|
|
- the raw API
|
||
|
|
- the system timer to to have certain functions called at regular intervals to
|
||
|
|
perform house-keeping tasks, such as handling TCP timeouts, retransmissions and so forth.
|
||
|
|
- Uses CGI and SSI
|
||
|
|
|
||
|
|
* fsdata.c is the flash file system, generated from the makefsdata folder using the makefsdata utility
|
||
|
|
- to generate new content for the server,
|
||
|
|
1. place your web content in the folder fs of makefsdata folder
|
||
|
|
2. run makefsdata without arguments
|
||
|
|
3. copy fsdata.c to the folder httpserver_raw using name fsdata.dat
|
||

Hardware Setup

===============
|
||
|
|
XMC4500 Relaxkit
|

|
|
|

|
|
How to test the application
|
||
|
|
============================
|
||
|
|
a. Copy the files to a new project
|
||
|
|
The following directories need to be added to the compiler include paths:
|
||
|
|
"${workspace_loc:/${ProjName}/lwip/include}"
|
||
|
|
"${workspace_loc:/${ProjName}/lwip/port/nosys/include}"
|
||
|
|
"${workspace_loc:/${ProjName}/lwip/port/nosys/netif}"
|
||
|
|
"${workspace_loc:/${ProjName}/httpserver_raw}"
|
||
|
|
|
||
|
|
The following macors need to be defined in the compiler settings:
|
||
|
|
XMC_ETH_PHY_KSZ8081RNB
|
||
|
|
|
||
|
|
b. Compile and flash the application onto the device
|
||
|
|
c. Run the application.
|
||
|
|
|
||
|
|
The IP address of the board is manual configured using 192.168.0.10.
|
||
|
|
Reconfigure PC network address to something like 192.168.0.11.
|
||
|
|
Direct your web browser at 192.168.0.10, a welcome message should be displayed.
|
||
|
|
Pressing the button toggles the LED1 of the Relaxkit.
|
||
|
|
|
||
|
|
NOTE: New batch of Relaxkit boards are using ksz8081 instead of ksz8031.
|
||
|
|
If the application hangs in the ethernetif_error function, please use the ksz8031 by replacing the C macro XMC_ETH_PHY_KSZ8081RNB by XMC_ETH_PHY_KSZ8031RNL in compiler settings.
