# Use two different rules for GPIO's.
|
|
#
|
|
# 1. The first rule (gpiochip0) allows to configure the GROUP and MODE of
|
|
# the 'export' and 'unexport' files. This is basically executed once on
|
|
# boot and it's needed so a normal user (with group 'digiapix')
|
|
# is able to export/unexport gpios.
|
|
#
|
|
# 2. The second rule configures the GROUP and MODE of the sysfs files that
|
|
# are created whenever a 'gpio' is exported.
|
|
#
|
|
# This way we filter out multiple gpiochipX events that we don't want to attend
|
