 | |
| \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
