<h3>PIFACE</h3>
<ul>
<b>Prerequesits</b>
<ul>
The PIFACE module managed the <a href=http://www.raspberrypi.org/>Raspberry Pi</a> extension board <a href=http://www.piface.org.uk/products/piface_digital/>PiFace Digital</a>.<br>
PIFACE controls the input ports 0..7 and output ports 0..7.
<ul>
<li>The relays 0 and 1 have corresponding output port 0 and 1.</li>
<li>The switches 0..3 have corresponding input ports 0..3 and must be read with attr portMode<0..7> = up</li>
</ul>
The status of the ports can be displayed periodically. The update of the states via interrupt is not supported.<br>
The module can be periodically monitored by a watchdog function.<br>
The ports can be read and controlled individually by the function <a href="#readingsProxy">readingsProxy</a>.<br>
PIFACE is tested with the Raspbian OS.<br><br>
<b>Preparatory Work</b><br>
The use of PIFACE module requires some preparatory work.
<ul>
<br>
<li>Module needs tools from <a href=http://wiringpi.com>Wiring Pi</a>. Install it with<br>
<code>git clone git://git.drogon.net/wiringPi<br>
cd wiringPi<br>
./build</code><br>
</li>
<li>PiFace Digital need the SPI pins on the Raspberry Pi to be enabled in order to function.
Start <code>sudo raspi-config</code>, select <code>Option 8 Advanced Options</code>
and set the <code>A5 SPI</code> option to "Yes".
</li>
<li>The function of the PiFace Digital can be tested at OS command line. For example:<br>
<code>gpio -p readall</code><br>
<code>gpio -p read 200</code><br>
<code>gpio -p write 201 0</code> or <code>gpio -p write 201 1</code><br>
</li>
<li>The watchdog function monitors the input port 7 and the output port 7.<br>
If the watchdog is enabled, this ports can not be used for other tasks.
In order to monitor the input port 7, it must be connected to the ground!<br>
The OS command "shutdown" must be enable for fhem if an OS restart is to
be executed in case of malfunction. For example, with <code>chmod +s /sbin/shutdown</code>
or <code>sudo chmod +s /sbin/shutdown</code>.<br>
</li>
</ul>

The function of the PiFace extension can be monitored periodically.
The watchdog module checks the function of ports in7 and out7.
If the watchdog function is to be used, ports in7 and out7 are reserved for this purpose.
The port 7 must be connected to ground.<br>
If [watchdog] = on, the result of which is periodically logged and written to the reading watchdog.<br>
If [watchdog] = silent, FHEM is restarted after the first error detected.
If the error could not be eliminated, then the Raspberry operating system is restarted.
If the error is not corrected as well, the monitoring function is disabled and the error is logged.
