mbedAustin 11:cada08fc8a70 26 \page cmsis_os_h Header File Template: cmsis_os.h
mbedAustin 11:cada08fc8a70 27
mbedAustin 11:cada08fc8a70 28 The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
mbedAustin 11:cada08fc8a70 29 Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
mbedAustin 11:cada08fc8a70 30 its implementation.
mbedAustin 11:cada08fc8a70 31
mbedAustin 11:cada08fc8a70 32 The file cmsis_os.h contains:
mbedAustin 11:cada08fc8a70 33 - CMSIS-RTOS API function definitions
mbedAustin 11:cada08fc8a70 34 - struct definitions for parameters and return types
mbedAustin 11:cada08fc8a70 35 - status and priority values used by CMSIS-RTOS API functions
mbedAustin 11:cada08fc8a70 36 - macros for defining threads and other kernel objects
mbedAustin 11:cada08fc8a70 37
mbedAustin 11:cada08fc8a70 38
mbedAustin 11:cada08fc8a70 39 <b>Name conventions and header file modifications</b>
mbedAustin 11:cada08fc8a70 40
mbedAustin 11:cada08fc8a70 41 All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
mbedAustin 11:cada08fc8a70 42 Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
mbedAustin 11:cada08fc8a70 43 All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
mbedAustin 11:cada08fc8a70 44
mbedAustin 11:cada08fc8a70 45 Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
mbedAustin 11:cada08fc8a70 46 These definitions can be specific to the underlying RTOS kernel.
mbedAustin 11:cada08fc8a70 47
mbedAustin 11:cada08fc8a70 48 Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
mbedAustin 11:cada08fc8a70 49 compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
mbedAustin 11:cada08fc8a70 50
mbedAustin 11:cada08fc8a70 51
mbedAustin 11:cada08fc8a70 52 <b>Function calls from interrupt service routines</b>
mbedAustin 11:cada08fc8a70 53
mbedAustin 11:cada08fc8a70 54 The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
mbedAustin 11:cada08fc8a70 55 - \ref osSignalSet
mbedAustin 11:cada08fc8a70 56 - \ref osSemaphoreRelease
mbedAustin 11:cada08fc8a70 57 - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
mbedAustin 11:cada08fc8a70 58 - \ref osMessagePut, \ref osMessageGet
mbedAustin 11:cada08fc8a70 59 - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
mbedAustin 11:cada08fc8a70 60
mbedAustin 11:cada08fc8a70 61 Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
mbedAustin 11:cada08fc8a70 62 from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
mbedAustin 11:cada08fc8a70 63
mbedAustin 11:cada08fc8a70 64 Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
mbedAustin 11:cada08fc8a70 65 If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
mbedAustin 11:cada08fc8a70 66
mbedAustin 11:cada08fc8a70 67
mbedAustin 11:cada08fc8a70 68 <b>Define and reference object definitions</b>
mbedAustin 11:cada08fc8a70 69
mbedAustin 11:cada08fc8a70 70 With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
mbedAustin 11:cada08fc8a70 71 that is used throughout a project as shown below:
mbedAustin 11:cada08fc8a70 72
mbedAustin 11:cada08fc8a70 73 <i>Header File</i>
mbedAustin 11:cada08fc8a70 74 \code
mbedAustin 11:cada08fc8a70 75 #include <cmsis_os.h> // CMSIS RTOS header file
mbedAustin 11:cada08fc8a70 76
mbedAustin 11:cada08fc8a70 77 // Thread definition
mbedAustin 11:cada08fc8a70 78 extern void thread_sample (void const *argument); // function prototype
mbedAustin 11:cada08fc8a70 79 osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
mbedAustin 11:cada08fc8a70 80
mbedAustin 11:cada08fc8a70 81 // Pool definition
mbedAustin 11:cada08fc8a70 82 osPoolDef(MyPool, 10, long);
mbedAustin 11:cada08fc8a70 83 \endcode
mbedAustin 11:cada08fc8a70 84
mbedAustin 11:cada08fc8a70 85
mbedAustin 11:cada08fc8a70 86 This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
mbedAustin 11:cada08fc8a70 87 present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
mbedAustin 11:cada08fc8a70 88 used throughout the whole project.
mbedAustin 11:cada08fc8a70 89
mbedAustin 11:cada08fc8a70 90 <i>Example</i>
mbedAustin 11:cada08fc8a70 91 \code
mbedAustin 11:cada08fc8a70 92 #include "osObjects.h" // Definition of the CMSIS-RTOS objects
mbedAustin 11:cada08fc8a70 93 \endcode
mbedAustin 11:cada08fc8a70 94
mbedAustin 11:cada08fc8a70 95 \code
mbedAustin 11:cada08fc8a70 96 #define osObjectExternal // Objects will be defined as external symbols
mbedAustin 11:cada08fc8a70 97 #include "osObjects.h" // Reference to the CMSIS-RTOS objects
mbedAustin 11:cada08fc8a70 98 \endcode
