<p>Release consists of the RTOS sources and three sample projects - see
<a class="reference" href="../index.html">Release description</a> for details. Each sample located in separate
folder. Structure of test project folder (folders are in brackets '[]'):</p>
<pre class="literal-block">
[Config] - linker scripts and other utilities
[Exe] - executable product[s]
[List] - listings and other temporary text files
[Obj] - objects and other intermediate files
[settings] - IAR IDE auxiliary files
[Src] - test project sources
slon.ewd - IAR IDE auxiliary file
slon.ewp - IAR IDE project
slon.eww - IAR IDE workspace
</pre>
<p><strong>slon</strong> is test project name.</p>
<p>Structure of the RTOS folder:</p>
<pre class="literal-block">

<p>There is only one way provided to build any sample - <strong>IAR IDE</strong>.</p>
<p>Just launch IDE, open appropriate workspace (*.eww file), choose project target (RAM/Flash),
and build the project.
Default chip type, the sample project is targeted for is LPC2119. To alter chip type, three
settings has to be changed:</p>
<ol class="arabic simple">
<li>Project->Options->General Options->Target->Device</li>
<li>Project->Options->C/C++ Compiler->Preprocessor->Defined symbols (consult device.h for appropriate value)</li>
<li>Project->Options->Assembler->Preprocessor->Defined symbols (consult device.h for appropriate value)</li>
</ol>
<p>If user want to use his own build system <a class="footnote-reference" href="#id3" id="id2" name="id2">[1]</a> he has to specify the following
command-line options for various tools:</p>

<p>This release supports only LPC2119, LPC2129, LPC2212, LPC2214 devices. If user wants to use other
LPC2xxx family device supported by compiler, two files has to be changed: <tt class="docutils literal"><span class="pre">device.h</span></tt> in Src folder
and <tt class="docutils literal"><span class="pre">OS_Target_core.h</span></tt> in scmRTOS/ARM7 folder. Contence of those files is simple enought.</p>
