    Warning
i2cset commands with wrong parameters can damage your system. Handle with care!
The bus number may change after a restart, don't hardcode it into your scripts.

Before you use any commands on this page you MUST find out the bus number for the led control on your system
Run
i2cdetect -y 0
	search=" 26 "
	i=0
	while [ "$i" -le 4 ]; do
	# echo "Trying bus $i"
	probe=`i2cdetect -y "$i" 2>&1`
	if echo "$probe" \| grep -q "$search"
	then
	echo "$i"
	exit 0
	fi
