<p id="GUID-D25228C5-D51E-54A3-A5D0-0B68A9E8E7C8"> Device Drivers are software
components that implement the interface between Symbian platform and peripherals.
Symbian platform provides drivers for many phone peripherals. </p>
<p>When you create a phone, you must: </p>
<ul>
<li id="GUID-B06430B3-BB1B-5050-8CD7-98B224B8D9F8"><p>make a decision which
drivers are needed for your phone. </p> </li>
<li id="GUID-0EA1EB70-D6BD-5B31-AD5E-25E73BB30098"><p>create a port of the
code that Symbian platform provides to work with your phone hardware. </p> </li>
</ul>
<p>This section describes the logical device drivers, the kernel trace tool
and the run mode debugger. </p>
