donatien 0:e6ccf0b3d718 20 \page cmsis_os_h Header File Template: cmsis_os.h
donatien 0:e6ccf0b3d718 21
donatien 0:e6ccf0b3d718 22 The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
donatien 0:e6ccf0b3d718 23 Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
donatien 0:e6ccf0b3d718 24 its implementation.
donatien 0:e6ccf0b3d718 25
donatien 0:e6ccf0b3d718 26 The file cmsis_os.h contains:
donatien 0:e6ccf0b3d718 27 - CMSIS-RTOS API function definitions
donatien 0:e6ccf0b3d718 28 - struct definitions for parameters and return types
donatien 0:e6ccf0b3d718 29 - status and priority values used by CMSIS-RTOS API functions
donatien 0:e6ccf0b3d718 30 - macros for defining threads and other kernel objects
donatien 0:e6ccf0b3d718 31
donatien 0:e6ccf0b3d718 32
donatien 0:e6ccf0b3d718 33 <b>Name conventions and header file modifications</b>
donatien 0:e6ccf0b3d718 34
donatien 0:e6ccf0b3d718 35 All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
donatien 0:e6ccf0b3d718 36 Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
donatien 0:e6ccf0b3d718 37 All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
donatien 0:e6ccf0b3d718 38
donatien 0:e6ccf0b3d718 39 Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
donatien 0:e6ccf0b3d718 40 These definitions can be specific to the underlying RTOS kernel.
donatien 0:e6ccf0b3d718 41
donatien 0:e6ccf0b3d718 42 Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
donatien 0:e6ccf0b3d718 43 compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
donatien 0:e6ccf0b3d718 44
donatien 0:e6ccf0b3d718 45
donatien 0:e6ccf0b3d718 46 <b>Function calls from interrupt service routines</b>
donatien 0:e6ccf0b3d718 47
donatien 0:e6ccf0b3d718 48 The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
donatien 0:e6ccf0b3d718 49 - \ref osSignalSet
donatien 0:e6ccf0b3d718 50 - \ref osSemaphoreRelease
donatien 0:e6ccf0b3d718 51 - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
donatien 0:e6ccf0b3d718 52 - \ref osMessagePut, \ref osMessageGet
donatien 0:e6ccf0b3d718 53 - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
donatien 0:e6ccf0b3d718 54
donatien 0:e6ccf0b3d718 55 Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
donatien 0:e6ccf0b3d718 56 from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
donatien 0:e6ccf0b3d718 57
donatien 0:e6ccf0b3d718 58 Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
donatien 0:e6ccf0b3d718 59 If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
donatien 0:e6ccf0b3d718 60
donatien 0:e6ccf0b3d718 61
donatien 0:e6ccf0b3d718 62 <b>Define and reference object definitions</b>
donatien 0:e6ccf0b3d718 63
donatien 0:e6ccf0b3d718 64 With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
donatien 0:e6ccf0b3d718 65 that is used troughtout a project as shown below:
donatien 0:e6ccf0b3d718 66
donatien 0:e6ccf0b3d718 67 <i>Header File</i>
donatien 0:e6ccf0b3d718 68 \code
donatien 0:e6ccf0b3d718 69 #include <cmsis_os.h> // CMSIS RTOS header file
donatien 0:e6ccf0b3d718 70
donatien 0:e6ccf0b3d718 71 // Thread definition
donatien 0:e6ccf0b3d718 72 extern void thread_sample (void const *argument); // function prototype
donatien 0:e6ccf0b3d718 73 osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
donatien 0:e6ccf0b3d718 74
donatien 0:e6ccf0b3d718 75 // Pool definition
donatien 0:e6ccf0b3d718 76 osPoolDef(MyPool, 10, long);
donatien 0:e6ccf0b3d718 77 \endcode
donatien 0:e6ccf0b3d718 78
donatien 0:e6ccf0b3d718 79
donatien 0:e6ccf0b3d718 80 This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
donatien 0:e6ccf0b3d718 81 present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
donatien 0:e6ccf0b3d718 82 used throughout the whole project.
donatien 0:e6ccf0b3d718 83
donatien 0:e6ccf0b3d718 84 <i>Example</i>
donatien 0:e6ccf0b3d718 85 \code
donatien 0:e6ccf0b3d718 86 #include "osObjects.h" // Definition of the CMSIS-RTOS objects
donatien 0:e6ccf0b3d718 87 \endcode
donatien 0:e6ccf0b3d718 88
donatien 0:e6ccf0b3d718 89 \code
donatien 0:e6ccf0b3d718 90 #define osObjectExternal // Objects will be defined as external symbols
donatien 0:e6ccf0b3d718 91 #include "osObjects.h" // Reference to the CMSIS-RTOS objects
donatien 0:e6ccf0b3d718 92 \endcode
