Openhab 1.7.1 problems accessing GPIO

[Joao Paulo Atila Rocha]

Hello friends.

I read a few cases in the forum, but my problem is not equal to none.

I will give more details:

----------------------------------------------------------------

Hardware = Raspberry 2.

OS = I'm using linux distro based on OSMC (media center).

Openhab = version 1.7.1

I follow all possible steps in the link:

# https://github.com/openhab/openhab/wiki/GPIO-Binding

I tried to run with the root user, but the daemon don't start, i changed the Following file:

# / Etc / default / openhab

this is the file that manages this function in this version:

# /usr/share/openhab/bin/openhab.in.sh

log message----------------------------------------------------------------

[ERROR] [.o.b.gpio.internal.GPIOBinding] - Error occured while creating backend object for item Light_FF_Office_Ceiling, exception: /sys/class/gpio/gpio18/active_low

[ERROR] [.o.b.gpio.internal.GPIOBinding] - Error occured while creating backend object for item Light_FF_Office_Ceiling, exception: Device or resource busy

I understand that it is a permission issue on Linux because I ran the following commands with the openhab user:

echo "18" > /sys/class/gpio/export

echo "out" > /sys/class/gpio/gpio18/direction (Permission denied)

echo "1" > /sys/class/gpio/gpio18/value (Permission denied)

if they can help me with a little knowledge I will be very grateful.

thank you for attention

Hello guys

I did some research and I resolved the problem of access to GPIO, follow details of how I resolved.

-------------------------------------------------------------------------------

nano /etc/udev/rules.d/998-fix-input.rules

KERNEL=="gpio18", SUBSYSTEM=="gpio", ACTION=="add", PROGRAM="/usr/bin/java /bin/sh"

KERNEL=="gpio*", SUBSYSTEM=="gpio", ACTION=="add", PROGRAM="/usr/bin/java gpio /sys%p"

SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c 'chown -R root:openhab /sys/class/gpio && chmod -R 770 /sys/class/gpio'"

-------------------------------------------------------------------------------

but I still can not turn on a lamp using openhab interface, I'll keep studying, if someone has an idea how to solve this problem, I will be very grateful.

It seems a problem with openhab configration (are you using a mao file ?).

Try to post .items and .sitemap files
