It's run on a Asus WL500gd with openwrt 0.9.
I managed to cross-compile imagemagick for openwrt, but I stumbled into a
major problem later. Imagemagick requires ghostscript, and that I never
succeeded to cross-compile that huge package for openwrt.
Ghostscript and imagemagick are available for NSLU2 though. So it should be
possible to use imagemagick on that device.

.5-3-1_armeb.ipk
I have made a simple web-interface to control some switches and
potentiometers via cgi-scripts too, but it's still a major hack and under
development.
Perhaps I can show it in a few days. I don't want to give out the URL to
Christian Schumann's web-interface even if it's password protected.

Christian,
What platform does this run on ?
I like the graphic....do you happen know if imagemagic runs on an unslung
NSLU2 ?
Did you implement control of any outputs from a web interface ?
thanks for sharing
cheers

Sorry, I copied an old script, and here is a bit more simplified error
check. Only test error-status "$?" is needed.
#!/bin/ash
readsensor () (
VAL=`owread -s 3002 $1/$2 2>&1`
ERR=$?
[ $ERR != 0 ] && {
date >>$DEBUGFILE
echo >>$DEBUGFILE "ERROR: owread $1 failed 1st time: $VAL"
VAL=`owread -s 3002 $1/$2 2>&1`
ERR=$?
[ $ERR != 0 ] && {
echo >>$DEBUGFILE "ERROR: owread $1 failed 2nd time: $VAL";
false; return;
}
}
# save last value to a file as well (mostly for web-server)
[ "$2" = "temperature" ] && echo "$VAL" > /tmp/last_val.$1.$2
echo "$VAL"
true;
)
writesensor () (
VAL=`owwrite -s 3002 $1/$2 $3 2>&1`
ERR=$?
[ $ERR != 0 ] && {
date >>$DEBUGFILE
echo >>$DEBUGFILE "ERROR: owwrite $1/$2 $3 failed 1st time."
VAL=`owwrite -s 3002 $1/$2 $3 2>&1`
ERR=$?
[ $ERR != 0 ] && {
echo >>$DEBUGFILE "ERROR: owwrite $1/$2 $3 failed 2nd time.";
false; return;
}
}
true;
)
VAL=`readsensor $SENSOR PIO`
ERR=$?
[ $ERR != 0 ] && exit 1
