keypad_load_pcparport.sh

之前在 embedded linux 上写 keypad driver 参考的源代码,有写 keypad driver 需要的朋友可以参考

#!/bin/sh
module="keypad"
device="keypad"
mode="664"

# Group: since distributions do it differently, look for wheel or use staff
#if grep '^staff:' /etc/group > /dev/null; then
#    group="staff"
#else
#    group="wheel"
#fi

# invoke insmod with all arguments we got
# and use a pathname, as newer modutils don't look in . by default
/sbin/insmod -f ./$module.o $* || exit 1

major=`cat /proc/devices | awk "\\$2==\"$module\" {print \\$1}"`

# Remove stale nodes and replace them, then give gid and perms
# Usually the script is shorter, it's scull that has several devices in it.

rm -f /dev/${device}

mknod /dev/${device} c $major 0


#chgrp $group /dev/${device}
#chmod $mode  /dev/${device}
