|
||||
* $Date: 5. February 2013
|
||||
* $Revision: V1.02
|
||||
*
|
||||
* Project: CMSIS-RTOS API
|
||||
* Title: cmsis_os.c
|
||||
*
|
||||
* Version 0.02
|
||||
* Initial Proposal Phase
|
||||
* Version 0.03
|
||||
* osKernelStart added, optional feature: main started as thread
|
||||
* osSemaphores have standard behavior
|
||||
* osTimerCreate does not start the timer, added osTimerStart
|
||||
* osThreadPass is renamed to osThreadYield
|
||||
* Version 1.01
|
||||
* Support for C++ interface
|
||||
* - const attribute removed from the osXxxxDef_t typedef's
|
||||
* - const attribute added to the osXxxxDef macros
|
||||
* Added: osTimerDelete, osMutexDelete, osSemaphoreDelete
|
||||
* Added: osKernelInitialize
|
||||
* Version 1.02
|
||||
* Control functions for short timeouts in microsecond resolution:
|
||||
* Added: osKernelSysTick, osKernelSysTickFrequency, osKernelSysTickMicroSec
|
||||
* Removed: osSignalGet
|
||||
*

\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
