Driver Examples</h1>
<p>The driver examples are full working CMSIS-Drivers that may be adapted to a different hardware. Examples are currently available for the NXP LPC1800 series and provide the implementation of a complete CMSIS-Driver. The following examples are available in the directory <b>.\CMSIS\Pack\Example\CMSIS_Driver</b>.</p>
<table class="doxtable">

<p>These CMSIS-Drivers use additional modules for GPIO and DMA control:</p>
<table class="doxtable">

<tr>
<td>SCU_LPC18xx.c </td><td>SCU_LPC18xx.h </td><td>SCU Interface for LPC1800 series </td></tr>
</table>
<p>The CMSIS-Drivers for the LPC1800 device have also many configuration options that are controls using #define statements in the file <b>.\CMSIS\Pack\Example\CMSIS_Driver\Config\RTE_Device.h</b>. Using this file, the I/O pin and DMA assignment can be set among other parameters such as USB speed and PHY interfaces.</p>
<p>Further driver reference implementations are available in Device Family Packs (DFP) labeled with version 2.0.0 or higher. </p>
