Hi!
here is the script i use to display messages on the LCD:
init the display:
=================
#! /bin/bash
cd /tmp/
cd /wetter/uncached/29.*/LCD_H
printf "\x0C" > screen
printf "1" > clear
printf "1" > clear
printf "1" > home
# printf "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" > screen
write messages:
===============
#! /bin/bash
cd /tmp/
# Sensor values
MSG[1]="$1"
MSG[2]="$2"
MSG[3]="$3"
MSG[4]="$4"
# Sensor names can be whatever you like
TEMP[1]="$5"
TEMP[2]="$6"
TEMP[3]="$7"
# TEMP[4]="$8"
cd /wetter/29.*/LCD_H
printf "1" > home
msg2=""
# for INDEX in 1 3 2 4
for INDEX in 1 3 2
do
msg=`printf '%-10s%-10s' "${MSG[$INDEX]}" "${TEMP[$INDEX]}"`
msg2="$msg2""$msg"
done
# last line just for long text
msg=`printf '%-20s' "${MSG[4]}"`
msg2="$msg2""$msg"
printf "$msg2" > screen
cheers,
Zoff.

that requires sensitive data to be transmitted over the Web. Learn how to
best implement a security strategy that keeps consumers' information secure
and instills the confidence they need to proceed with transactions.
