-/**
-\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 throughout 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

-\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 throughout 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
