<h1>Configuration options for uIP</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
uIP is configured using the per-project configuration file <a class="el" href="a00140.html">uipopt.h</a>.
<p>
This file contains all compile-time options for uIP and should be tweaked to match each specific project. The uIP distribution contains a documented example "uipopt.h" that can be copied and modified for each project.<p>
<dl compact><dt><b>Note:</b></dt><dd>Most of the configuration options in the <a class="el" href="a00140.html">uipopt.h</a> should not be changed, but rather the per-project uip-conf.h file. </dd></dl>

Turn on support for IP packet reassembly.
<p>
uIP supports reassembly of fragmented IP packets. This features requires an additonal amount of RAM to hold the reassembly buffer and the reassembly code size is approximately 700 bytes. The reassembly buffer is of the same size as the uip_buf buffer (configured by UIP_BUFSIZE).<p>
