I also written some scripts for the GPIO pins first off all I wrote a script to initialize all the pins that I have connected

Code:

#!/bin/sh
#RED - RGB-strip
echo 79 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio79/direction
#BIG - Case Button
echo 80 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio80/direction
#POWER - Case Led
echo 81 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio81/direction
#FAN - Case fan
echo 82 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio82/direction
#RPM_FAN - Case fan
echo 83 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio83/direction
#GREEN - RGB-strip
echo 84 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio84/direction
#SMALL - Case Button
echo 85 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio85/direction
#BLUE - RGB-strip
echo 86 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio86/direction
#HDD - Case Button
echo 87 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio87/direction

To test all these pins I also wrote a script

Code:

#!/bin/bash
#MikeD
#Test all pins in use
LOOPS=5
ON_TIME=.5
OFF_TIME=.25

At last I wrote a script to power my fan in function of the temperature

Code:

#!/bin/bash
#MikeD Automatic fan on cpu temp
 
CHECK_TIME=10 #IN SEC
 
function pwm(){
LOOP=0
while [ $LOOP -lt $(($CHECK_TIME*75)) ]; do
        echo 1 > /sys/class/gpio/gpio82/value
        sleep $1
        echo 0 > /sys/class/gpio/gpio82/value
        sleep $2
        LOOP=$(($LOOP+1))
done
}
 
function fanOff() {
                echo 0 > /sys/class/gpio/gpio82/value
                sleep $CHECK_TIME
}
 
function fanTweFiv() {
                pwm .025 .075
}
 
function fanFifty() {
                pwm .050 .050
}
 
function fanSevFiv() {
                pwm .075 .025
}
 
function fanFull() {
                echo 1 > /sys/class/gpio/gpio82/value
                sleep $CHECK_TIME
}
 
while [ 1 ]; do
        TEMP=$(cat /sys/class/thermal/thermal_zone0/temp)
 
if [ $TEMP -le 20000 ]
then
                fanOff
fi
 
if [ $TEMP -gt 20000 -a $TEMP -le 25000 ]
then
                fanTweFiv
fi
 
if [ $TEMP -gt 25000 -a $TEMP -le 35000 ]
then
                fanFifty
fi
 
if [ $TEMP -gt 35000 -a $TEMP -le 45000 ]
then
                fanSevFiv
fi
 
if [ $TEMP -gt 45000 ]
then
                fanFull
fi
 
done
