<div class="textblock"><p>Example projects using CMSIS-RTOS RTX are available for various development boards. To make use of these examples, you need to install a Device Family Pack in µVision and use Pack Installer to open a CMSIS-RTOS Blinky project. If you wish to start a CMSIS-RTOS RTX from scratch, follow these steps:</p>
<ul>
<li>Create a new project and select a device.</li>
<li><p class="startli">In the Manage Run-Time Environment window that opens, select <b>CMSIS::CORE</b> and <b>CMSIS::RTOS (API)::Keil RTX</b>. If the <b>Validation Output</b> requires other components to be present, try to use the <b>Resolve</b> button:</p>
<div class="image">
<img src="manage_rte_output.png" alt="manage_rte_output.png"/>
</div>
</li>
</ul>
<ul>
<li><p class="startli">Click <b>OK</b>. In the <b>Project</b> window, you will see the files that have been automatically added to you project, such as <b>RTX_Conf_CM.c</b> and the system and startup files:</p>
<div class="image">

</div>
</li>
</ul>
<ul>
<li><p class="startli">You can add template files to the project by right-clicking on <b>Source Group 1</b> and selecting <b>Add New Item to 'Source Group 1'</b>. In the new window, click on <b>User Code Template</b>. On the right-hand side you will see all available template files for CMSIS-RTOS RTX:</p>

Define and Reference Object Definitions</h1>
<p>With <code>#define</code> <code>osObjectsExternal</code> objects are defined as external symbols. This allows to create a consistent header file that is used throughout a project. If you are using the <b>CMSIS-RTOS</b> <b>'main'</b> <b>function</b> user code template, such a header file (called <code>osObjects.h</code>) will be added automatically to the project:</p>
