+/**
+\page cmsis_os_h Header File Template: cmsis_os.h
+
+The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
+Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
+its implementation.
+
+The file cmsis_os.h contains:
+ - CMSIS-RTOS API function definitions
+ - struct definitions for parameters and return types
+ - status and priority values used by CMSIS-RTOS API functions
+ - macros for defining threads and other kernel objects
+
+
+<b>Name conventions and header file modifications</b>
+
+All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
+Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
+All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
+ 
+Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation. 
+These definitions can be specific to the underlying RTOS kernel.
+
+Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
+compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
+
+
+<b>Function calls from interrupt service routines</b>
+
+The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
+  - \ref osSignalSet
+  - \ref osSemaphoreRelease
+  - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
+  - \ref osMessagePut, \ref osMessageGet
+  - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
+
+Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called 
+from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
+
+Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
+If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
+
+
+<b>Define and reference object definitions</b>
+
+With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
+that is used troughtout a project as shown below:
+
+<i>Header File</i>
+\code
+#include <cmsis_os.h>                                         // CMSIS RTOS header file
+
+// Thread definition
+extern void thread_sample (void const *argument);             // function prototype
+osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
+
+// Pool definition
+osPoolDef(MyPool, 10, long);                      
+\endcode
+
+
+This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is 
+present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
+used throughout the whole project.
+
+<i>Example</i>
+\code
+#include "osObjects.h"     // Definition of the CMSIS-RTOS objects
+\endcode
+
+\code
+#define osObjectExternal   // Objects will be defined as external symbols
+#include "osObjects.h"     // Reference to the CMSIS-RTOS objects
+\endcode
