<p>It is possible to access the GPIO pins using a kernel device driver instead of accessing the pins directly through /dev/mem. This has the advantage that you can set up the device driver options so that pin access does not require root permissions.</p>
<p>This panel allows you to setup and manage the <A HREF="topic_gpiodev.htm">GPIO Device Driver</A> settings and pins.</p>
<p>Access to the pins can be granted to members of the group <I><B>gpio</B></I>. The panel provides a simple interface that allows you to toggle this option on and off using the 'Allow Group Access' checkbox and also manage group membership</p>
<p>Changes to the 'Allow Group Access' setting will persist across system reboots.</p>
<p><b>Several of these options are not applicable when the system is running using the device tree and in that case the options will be disabled.</b></p>
