Was the script on your system? I just realized that the input --low
option didn't work for a push button. It was originally setup for the
audiophonics board. Using inputs as low is much safer......less chance
of connecting voltage to the wrong pin.
So here is the fixed script.
Code:
--------------------
#!/bin/sh
#
# piCorePlayer Power Button Script - Used to shutdown pCP with a GPIO input.
#
# Version 1.1 2018-06-24
# Bug fix for --low
#
#
# Defaults are for the Audiophonics power button
DEBUG=0
IN_LOW=0
PIN_IN=17
PIN_OUT=22
PUPDOWN="off"
PATH=/bin:/usr/bin:/usr/local/bin
usage() {
echo " usage: $0 [-i] [-o] [--low] [--help] [--debug]"
echo " -i GPIO input pin to shutdown pCP"
echo " -o GPIO output pin for successful pCP boot"
echo " --low Input is active low (and set pull up
resistor)"
echo " --high Input is active high (and set pull down
resistor)"
echo " --debug Script run as normal, but will not shutdown
pCP"
echo " --help script usage"
echo ""
echo " Note: pin numbers are in BCM notation"
echo ""
exit 1
}
validate_pin(){
VAL=$(echo $1 | grep -o '[[:digit:]]*')
if [ "$VAL" != "" ]; then
if [ $VAL -le 31 ]; then
return 0
fi
fi
return 1
}
O=$(/usr/bin/getopt -al help,low,high,debug -- i:o:h "$@") || exit 1
eval set -- "$O"
[ "$1" = "--" ] && echo "No command line settings, Using defaults"; echo ""
while true; do
case "$1" in
-i) PIN_IN=$2; shift;;
-o) PIN_OUT=$2; shift;;
--debug) DEBUG=1;;
--low) IN_LOW=1; PUPDOWN="up";;
--high) IN_LOW=0; PUPDOWN="down";;
--help) usage;;
--) shift; break;;
-*) usage;;
*) break;;
esac
shift
done
echo "piCorePlayer Power button shutdown script starting..."
validate_pin $PIN_IN
if [ $? -ne 0 ]; then
echo "Error in Input Pin Assignment"
exit 1
fi
validate_pin $PIN_OUT
if [ $? -ne 0 ]; then
echo "Error in Output Pin Assignment"
exit 1
fi
echo "Asserting pins : "
echo -n "ShutDown : GPIO${PIN_IN}=in, "
[ ${IN_LOW} -eq 1 ] && echo "Low" || echo "High"
echo "BootOK : GPIO${PIN_OUT}=out, High"
gpio -g mode $PIN_IN in
gpio -g mode $PIN_IN $PUPDOWN
gpio -g mode $PIN_OUT out
gpio -g write $PIN_OUT 1
[ $IN_LOW -eq 0 ] && IN_CHK=1 || IN_CHK=0
while [ 1 ]; do
if [ "$(/usr/local/bin/gpio -g read ${PIN_IN})" = "$IN_CHK" ]; then
echo "piCorePlayer shutting down."
[ $DEBUG -eq 0 ] && sudo /sbin/poweroff
break
fi
/bin/sleep 1
done
exit 0
