mbed_official 80:2dab120a94c2 26 \page cmsis_os_h Header File Template: cmsis_os.h
mbed_official 80:2dab120a94c2 27
mbed_official 80:2dab120a94c2 28 The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
mbed_official 80:2dab120a94c2 29 Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
mbed_official 80:2dab120a94c2 30 its implementation.
mbed_official 80:2dab120a94c2 31
mbed_official 80:2dab120a94c2 32 The file cmsis_os.h contains:
mbed_official 80:2dab120a94c2 33 - CMSIS-RTOS API function definitions
mbed_official 80:2dab120a94c2 34 - struct definitions for parameters and return types
mbed_official 80:2dab120a94c2 35 - status and priority values used by CMSIS-RTOS API functions
mbed_official 80:2dab120a94c2 36 - macros for defining threads and other kernel objects
mbed_official 80:2dab120a94c2 37
mbed_official 80:2dab120a94c2 38
mbed_official 80:2dab120a94c2 39 <b>Name conventions and header file modifications</b>
mbed_official 80:2dab120a94c2 40
mbed_official 80:2dab120a94c2 41 All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
mbed_official 80:2dab120a94c2 42 Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
mbed_official 80:2dab120a94c2 43 All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
mbed_official 80:2dab120a94c2 44
mbed_official 80:2dab120a94c2 45 Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
mbed_official 80:2dab120a94c2 46 These definitions can be specific to the underlying RTOS kernel.
mbed_official 80:2dab120a94c2 47
mbed_official 80:2dab120a94c2 48 Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
mbed_official 80:2dab120a94c2 49 compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
mbed_official 80:2dab120a94c2 50
mbed_official 80:2dab120a94c2 51
mbed_official 80:2dab120a94c2 52 <b>Function calls from interrupt service routines</b>
mbed_official 80:2dab120a94c2 53
mbed_official 80:2dab120a94c2 54 The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
mbed_official 80:2dab120a94c2 55 - \ref osSignalSet
mbed_official 80:2dab120a94c2 56 - \ref osSemaphoreRelease
mbed_official 80:2dab120a94c2 57 - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
mbed_official 80:2dab120a94c2 58 - \ref osMessagePut, \ref osMessageGet
mbed_official 80:2dab120a94c2 59 - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
mbed_official 80:2dab120a94c2 60
mbed_official 80:2dab120a94c2 61 Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
mbed_official 80:2dab120a94c2 62 from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
mbed_official 80:2dab120a94c2 63
mbed_official 80:2dab120a94c2 64 Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
mbed_official 80:2dab120a94c2 65 If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
mbed_official 80:2dab120a94c2 66
mbed_official 80:2dab120a94c2 67
mbed_official 80:2dab120a94c2 68 <b>Define and reference object definitions</b>
mbed_official 80:2dab120a94c2 69
mbed_official 80:2dab120a94c2 70 With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
mbed_official 80:2dab120a94c2 71 that is used throughout a project as shown below:
mbed_official 80:2dab120a94c2 72
mbed_official 80:2dab120a94c2 73 <i>Header File</i>
mbed_official 80:2dab120a94c2 74 \code
mbed_official 80:2dab120a94c2 75 #include <cmsis_os.h> // CMSIS RTOS header file
mbed_official 80:2dab120a94c2 76
mbed_official 80:2dab120a94c2 77 // Thread definition
mbed_official 80:2dab120a94c2 78 extern void thread_sample (void const *argument); // function prototype
mbed_official 80:2dab120a94c2 79 osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
mbed_official 80:2dab120a94c2 80
mbed_official 80:2dab120a94c2 81 // Pool definition
mbed_official 80:2dab120a94c2 82 osPoolDef(MyPool, 10, long);
mbed_official 80:2dab120a94c2 83 \endcode
mbed_official 80:2dab120a94c2 84
mbed_official 80:2dab120a94c2 85
mbed_official 80:2dab120a94c2 86 This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
mbed_official 80:2dab120a94c2 87 present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
mbed_official 80:2dab120a94c2 88 used throughout the whole project.
mbed_official 80:2dab120a94c2 89
mbed_official 80:2dab120a94c2 90 <i>Example</i>
mbed_official 80:2dab120a94c2 91 \code
mbed_official 80:2dab120a94c2 92 #include "osObjects.h" // Definition of the CMSIS-RTOS objects
mbed_official 80:2dab120a94c2 93 \endcode
mbed_official 80:2dab120a94c2 94
mbed_official 80:2dab120a94c2 95 \code
mbed_official 80:2dab120a94c2 96 #define osObjectExternal // Objects will be defined as external symbols
mbed_official 80:2dab120a94c2 97 #include "osObjects.h" // Reference to the CMSIS-RTOS objects
mbed_official 80:2dab120a94c2 98 \endcode
