logging time of death (or other values) in DS1307

[flavigny]

Hello,
at this time, when my O'Maxi crashes I lost SdCard, here is an easy way to keep some values, for me last time running.
I connected a (3$ clock-chip: DS1307; see previous post) and installed i2c-tools
I wrote script copying time in external memory:
prepare script x:
[root@alarm ~]# cat > x
#!/bin/sh
while [ true ]
do
for i in {0..6}
do
i2cset -y 0 104 0x1$i `i2cget -y 0 104 $i`
done
sleep 1
done
^d

start it:
[root@alarm ~]# chmod +x x
[root@alarm ~]# ./x&
[1] 337
[root@alarm ~]#

watch logged time:
[root@alarm ~]# i2cdump -y -r 0-31 0 104 b
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00: 47 16 07 04 12 0b 0c 13 27 40 47 07 07 04 12 0b
10: 45 16 07 04 12 0b 0c 00 30 38 54 29 20 16 01 82

[root@alarm ~]#
