To add the RTOS functionality to an existing CMSIS-based application, the RTOS library (and typically a configuration file) needs to be added. The available functionality of the RTOS library is defined in the header file <b><a class="el" href="cmsis__os_8h.html">cmsis_os.h</a></b> that is specific for each CMSIS-RTOS implementation.</p> +<div class="image"> +<img src="CMSIS_RTOS_Files.png" alt="CMSIS_RTOS_Files.png"/> +<div class="caption"> +CMSIS-RTOS File Structure</div></div> +<p> Depending on the CMSIS-RTOS implementation, execution may start with the <b>main</b> function as the first thread. This has the benefit that an application programmer may use other middleware libraries that create threads internally, but the remaining part of the user application just uses the <b>main</b> thread. Therefore, the usage of the RTOS can be invisible to the application programmer, but libraries can use CMSIS-RTOS features.</p> +<p>Once the files are added to a project, the user can start working with the CMSIS-RTOS functions.
