webserver IPv6 raven
|
|
====================
|
|
|
|
This example features a simple webserver running on top of the IPv6 contiki
|
|
stack. It differs from the generic webserver6 example in that wherever possible
|
|
data is stored in AVR flash memory instead of RAM. In addition are cgi scripts
|
|
for displaying temperature and voltage sensors, and sleep and radio statistics,
|
|
on web pages.
|
|
|
|
A bare $make will use the avr-raven platform. Alternate compatible platforms
|
|
can be specified, e.g. $make TARGET=avr-atmega128rfa1. In that case the
|
|
webserver process and web content located in that platform directory will be
|
|
used.
|
|
|
|
The perl script /tools/makefsdata converts web content from (by default)
|
|
all the files in the /httpd-fs subdirectory into the c source file /httpd-fsdata.c.
|
|
This file is not deleted in a $make clean so that a rebuild can be done without
|
|
perl in the toolchain (e.g. from a Windows cmd window). If any web file is
|
|
changed the dependencies will attempt to update httpd-fsdata.c. If perl
|
|
is not present, touching httpd-fsdata.c will give it a newer modification date
|
|
and allow the build to continue.
|
|
|
|
Two alternate web contents Huginn and Muninn are included in this directory.
|
|
Use e.g. $make WEBDIR=Huginn to generate a webserver6-huginn.elf file.
|
|
Different ipv6 address suffix and server names can be specified in the makefsdata.h
|
|
file of each directory so that mote addresses will not conflict.
|
|
|
|
webserver6.elf is always generated. It is also copied to another file whose
|
|
name indicates the platform and web directory. $make clean operates only the
|
|
specified target and webdir. For example:
|
|
|
|
make # builds webserver6.elf and webserver6-avr-raven.elf
|
|
make WEBDIR=huginn # builds webserver6.elf and webserver6-huginn-avr-raven.elf
|
|
make WEBDIR=muninn TARGET=avr-atmega128rfa1 # (builds webserver6.elf and webserver6-muninn-avr-atmega128rfa1.elf)
|
|
make clean WEBDIR=huginn TARGET=avr-atmega128rfa1 # deletes the avr-atmega128rfa1 objects and webserver6-huginn-avr-atmega128rfa1.elf
|
|
make clean # deletes the avr-raven objects and webserver6-avr-raven.elf
|
|
|
|
|
|
make WEBDIR=xxx
|
|
|
|
always forces regeneration of web content into httpd-fsdata.c and so requires
|
|
PERL. A bare $make after that will not regenerate httpd-fsdata.c. Use
|
|
|
|
make WEBDIR=default
|
|
|
|
to switch back to the default /http-fs/ content.
|
|
|
|
See Makefile.webserver for optional switches for RPL or a coffee file system.
|
|
|
|
make UIP_CONF_RPL=1 # for a RPL node, or if rpl has become the contiki default,
|
|
make UIP_CONF_RPL=0 # to override
|
|
|
|
Much head banging can result if you do not _make clean_ when changing make
|
|
options, as the normal build dependencies are bypassed and the needed object
|
|
modules may not be rebuilt.

Connect
|
|
-------
|
|
|
|
make connect
|
|
|
|
will invoke the /tools/serial-log.pl perl script to connect to your serial
|
|
debug port. This will log to the console and optional log file, adding useful
|
|
time stamps. Edit the makefile for your serial port configuration.
