mbed_official 48:e9a2c7cb57a4 50 \page cmsis_os_h Header File Template: cmsis_os.h
mbed_official 48:e9a2c7cb57a4 51
mbed_official 48:e9a2c7cb57a4 52 The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
mbed_official 48:e9a2c7cb57a4 53 Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
mbed_official 48:e9a2c7cb57a4 54 its implementation.
mbed_official 48:e9a2c7cb57a4 55
mbed_official 48:e9a2c7cb57a4 56 The file cmsis_os.h contains:
mbed_official 48:e9a2c7cb57a4 57 - CMSIS-RTOS API function definitions
mbed_official 48:e9a2c7cb57a4 58 - struct definitions for parameters and return types
mbed_official 48:e9a2c7cb57a4 59 - status and priority values used by CMSIS-RTOS API functions
mbed_official 48:e9a2c7cb57a4 60 - macros for defining threads and other kernel objects
mbed_official 48:e9a2c7cb57a4 61
mbed_official 48:e9a2c7cb57a4 62
mbed_official 48:e9a2c7cb57a4 63 <b>Name conventions and header file modifications</b>
mbed_official 48:e9a2c7cb57a4 64
mbed_official 48:e9a2c7cb57a4 65 All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
mbed_official 48:e9a2c7cb57a4 66 Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
mbed_official 48:e9a2c7cb57a4 67 All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
mbed_official 48:e9a2c7cb57a4 68
mbed_official 48:e9a2c7cb57a4 69 Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
mbed_official 48:e9a2c7cb57a4 70 These definitions can be specific to the underlying RTOS kernel.
mbed_official 48:e9a2c7cb57a4 71
mbed_official 48:e9a2c7cb57a4 72 Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
mbed_official 48:e9a2c7cb57a4 73 compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
mbed_official 48:e9a2c7cb57a4 74
mbed_official 48:e9a2c7cb57a4 75
mbed_official 48:e9a2c7cb57a4 76 <b>Function calls from interrupt service routines</b>
mbed_official 48:e9a2c7cb57a4 77
mbed_official 48:e9a2c7cb57a4 78 The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
mbed_official 48:e9a2c7cb57a4 79 - \ref osSignalSet
mbed_official 48:e9a2c7cb57a4 80 - \ref osSemaphoreRelease
mbed_official 48:e9a2c7cb57a4 81 - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
mbed_official 48:e9a2c7cb57a4 82 - \ref osMessagePut, \ref osMessageGet
mbed_official 48:e9a2c7cb57a4 83 - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
mbed_official 48:e9a2c7cb57a4 84
mbed_official 48:e9a2c7cb57a4 85 Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
mbed_official 48:e9a2c7cb57a4 86 from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
mbed_official 48:e9a2c7cb57a4 87
mbed_official 48:e9a2c7cb57a4 88 Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
mbed_official 48:e9a2c7cb57a4 89 If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
mbed_official 48:e9a2c7cb57a4 90
mbed_official 48:e9a2c7cb57a4 91
mbed_official 48:e9a2c7cb57a4 92 <b>Define and reference object definitions</b>
mbed_official 48:e9a2c7cb57a4 93
mbed_official 48:e9a2c7cb57a4 94 With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
mbed_official 48:e9a2c7cb57a4 95 that is used throughout a project as shown below:
mbed_official 48:e9a2c7cb57a4 96
mbed_official 48:e9a2c7cb57a4 97 <i>Header File</i>
mbed_official 48:e9a2c7cb57a4 98 \code
mbed_official 48:e9a2c7cb57a4 99 #include <cmsis_os.h> // CMSIS RTOS header file
mbed_official 48:e9a2c7cb57a4 100
mbed_official 48:e9a2c7cb57a4 101 // Thread definition
mbed_official 48:e9a2c7cb57a4 102 extern void thread_sample (void const *argument); // function prototype
mbed_official 48:e9a2c7cb57a4 103 osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
mbed_official 48:e9a2c7cb57a4 104
mbed_official 48:e9a2c7cb57a4 105 // Pool definition
mbed_official 48:e9a2c7cb57a4 106 osPoolDef(MyPool, 10, long);
mbed_official 48:e9a2c7cb57a4 107 \endcode
mbed_official 48:e9a2c7cb57a4 108
mbed_official 48:e9a2c7cb57a4 109
mbed_official 48:e9a2c7cb57a4 110 This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
mbed_official 48:e9a2c7cb57a4 111 present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
mbed_official 48:e9a2c7cb57a4 112 used throughout the whole project.
mbed_official 48:e9a2c7cb57a4 113
mbed_official 48:e9a2c7cb57a4 114 <i>Example</i>
mbed_official 48:e9a2c7cb57a4 115 \code
mbed_official 48:e9a2c7cb57a4 116 #include "osObjects.h" // Definition of the CMSIS-RTOS objects
mbed_official 48:e9a2c7cb57a4 117 \endcode
mbed_official 48:e9a2c7cb57a4 118
mbed_official 48:e9a2c7cb57a4 119 \code
mbed_official 48:e9a2c7cb57a4 120 #define osObjectExternal // Objects will be defined as external symbols
mbed_official 48:e9a2c7cb57a4 121 #include "osObjects.h" // Reference to the CMSIS-RTOS objects
mbed_official 48:e9a2c7cb57a4 122 \endcode
