|

# An FHEM Perl module to control RaspberryPi extension board PiFace
|
||||
#
|
||||
# The PiFace is an add-on board for the Raspberry Pi featuring 8 open-collector outputs,
|
||||
# with 2 relays and 8 inputs (with 4 on-board buttons).
|
||||
# These functions are fairly well fixed in the hardware,
|
||||
# so only the read, write and internal pull-up commands are implemented.
|
||||
#
|
||||
# Please read commandref for details on prerequisits!
|
||||
# Depends on wiringPi library from http://wiringpi.com
