<div class="textblock"><p>The element <a class="el" href="pdsc_components_pg.html#element_components">/package/components</a> describes software components contained in the PACK. A component lists the files that belong to a component and that are relevant for a project. The component itself or each individual file may refer to a <a class="el" href="pdsc_conditions_pg.html#element_condition">condition</a> that must resolve to true; if it is false the component or file is not applicable in the given context.</p>
<p>Each component must have a Class (Cclass=), a Group (Cgroup=), and a Version (Cversion=) which is used to identify the component. Optionally a component may have a Sub-Group (Csub=) and Variant (Cvariant=) to add further categories. The Class, Group, Sub-Group, Variant and Version is used together with the vendor specified by the PACK, to identify a component. A component vendor must ensure that the combination Class, Group, Sub-Group and Version is unique and not used by multiple components.</p>

<h1><a class="anchor" id="Component_Bundle"></a>
Component Bundle</h1>
<p>In case multiple inter-dependent components that belong to the same <b>Cclass</b> form part of a solution, these can be grouped into a <em>bundle</em>. A <em>bundle</em> specifies identical attributes <b>Cclass</b>, <b>Cversion</b> and optionally <b>Cgroup</b> and <b>Cvendor</b> for several components. Components within a bundle inherit these attributes set by the bundle and cannot alter these attributes. Bundles ensure consistency of attributes across multiple interworking components and restrict the mix and match of components within a Cclass from different Software Packs.</p>
<p>An example of a <b>bundle</b> is shown in the <a class="el" href="createPackBoard.html#cp_BundleExample">Create a BSP Bundle</a> section where the bundle is used to deliver board support files for a certain development platform.</p>
<h1><a class="anchor" id="Component_Files"></a>
Component Files</h1>
<p>The files of a Software Component will be used in development tool-chains to build an application. Depending on the attributes, the files are handled differently:</p>
<ul>
<li>Libraries, source, and header files without an attribute cannot be modified. These files are stored in the folders of the Software Component and get directly included from this location into the project.</li>
<li>Source and header files that have the attribute <code>"config"</code> are copied to the project so that they can be edited by the user and tailored to the needs of the application. If a Software Component allows multiple instances of files, they can be copied multiple times to a project and will get a suffix <em>_%Instance%</em> (see <a class="el" href="pdsc_components_pg.html#Component_Instances">Component Instances</a>). Please note that header files that are used with the attribute <code>"config"</code> need to be stored separately from other header files (for example in an extra directory) to avoid that due to the include path search order of the compiler, the unmodified header file in the pack repository is found first and used by the compiler (creating unexpected results).</li>
<li>Source and header files that have the attribute <code>"template"</code> are part of <a class="el" href="cp_SWComponents.html#cp_CodeTemplates">User Code Templates</a> and can be added to a project manually by the user.</li>
</ul>
<p>The following image shows the dependency between the attribute and the display in a development environment:</p>
<div class="image">
<img src="component_files.png" alt="component_files.png"/>
<div class="caption">
Display of files of a Software Component in development tools</div></div>
<h1><a class="anchor" id="Component_Instances"></a>
Component Instances</h1>
<p>Modern microcontrollers often have multiple instances of the same peripheral interface (for example UART, SPI, USB, etc.). To be able to have separate configuration files for each of these instances, Software Components can have multiple instances as well. The attribute <b>maxInstances</b> declares the maximum number of instances that can be used in a project for a certain Software Component.</p>
<p>If the user selects for example two instances of the same component, all files with the attribute <code>"config"</code> will be copied twice to the project. The name of the component (for example <code>config_mylib.h</code>) will be expanded with an <code>_%Instance%</code> number:</p>
<ol type="1">
<li>Instance: config_mylib<em>_0</em>.h</li>
<li>Instance: config_mylib<em>_1</em>.h</li>
</ol>
<p>The availability of instances in a project can be made public in the <code>RTE_Components.h</code> file. This can be used to check for the availability of a certain instance in the user application code:</p>

<h1><a class="anchor" id="RTE_Components_h"></a>
RTE_Components.h</h1>
<p>The build environment should generate a C/C++ include file with the name <b>RTE_Components.h</b> that contains:</p>
<ul>
<li>The statements of the related &lt;RTE_Components_h&gt; element for all selected software components.</li>
