DieterGraef 0:f9b6112278fe 26 \page cmsis_os_h Header File Template: cmsis_os.h
DieterGraef 0:f9b6112278fe 27
DieterGraef 0:f9b6112278fe 28 The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
DieterGraef 0:f9b6112278fe 29 Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
DieterGraef 0:f9b6112278fe 30 its implementation.
DieterGraef 0:f9b6112278fe 31
DieterGraef 0:f9b6112278fe 32 The file cmsis_os.h contains:
DieterGraef 0:f9b6112278fe 33 - CMSIS-RTOS API function definitions
DieterGraef 0:f9b6112278fe 34 - struct definitions for parameters and return types
DieterGraef 0:f9b6112278fe 35 - status and priority values used by CMSIS-RTOS API functions
DieterGraef 0:f9b6112278fe 36 - macros for defining threads and other kernel objects
DieterGraef 0:f9b6112278fe 37
DieterGraef 0:f9b6112278fe 38
DieterGraef 0:f9b6112278fe 39 <b>Name conventions and header file modifications</b>
DieterGraef 0:f9b6112278fe 40
DieterGraef 0:f9b6112278fe 41 All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
DieterGraef 0:f9b6112278fe 42 Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
DieterGraef 0:f9b6112278fe 43 All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
DieterGraef 0:f9b6112278fe 44
DieterGraef 0:f9b6112278fe 45 Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
DieterGraef 0:f9b6112278fe 46 These definitions can be specific to the underlying RTOS kernel.
DieterGraef 0:f9b6112278fe 47
DieterGraef 0:f9b6112278fe 48 Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
DieterGraef 0:f9b6112278fe 49 compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
DieterGraef 0:f9b6112278fe 50
DieterGraef 0:f9b6112278fe 51
DieterGraef 0:f9b6112278fe 52 <b>Function calls from interrupt service routines</b>
DieterGraef 0:f9b6112278fe 53
DieterGraef 0:f9b6112278fe 54 The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
DieterGraef 0:f9b6112278fe 55 - \ref osSignalSet
DieterGraef 0:f9b6112278fe 56 - \ref osSemaphoreRelease
DieterGraef 0:f9b6112278fe 57 - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
DieterGraef 0:f9b6112278fe 58 - \ref osMessagePut, \ref osMessageGet
DieterGraef 0:f9b6112278fe 59 - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
DieterGraef 0:f9b6112278fe 60
DieterGraef 0:f9b6112278fe 61 Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
DieterGraef 0:f9b6112278fe 62 from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
DieterGraef 0:f9b6112278fe 63
DieterGraef 0:f9b6112278fe 64 Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
DieterGraef 0:f9b6112278fe 65 If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
DieterGraef 0:f9b6112278fe 66
DieterGraef 0:f9b6112278fe 67
DieterGraef 0:f9b6112278fe 68 <b>Define and reference object definitions</b>
DieterGraef 0:f9b6112278fe 69
DieterGraef 0:f9b6112278fe 70 With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
DieterGraef 0:f9b6112278fe 71 that is used throughout a project as shown below:
DieterGraef 0:f9b6112278fe 72
DieterGraef 0:f9b6112278fe 73 <i>Header File</i>
DieterGraef 0:f9b6112278fe 74 \code
DieterGraef 0:f9b6112278fe 75 #include <cmsis_os.h> // CMSIS RTOS header file
DieterGraef 0:f9b6112278fe 76
DieterGraef 0:f9b6112278fe 77 // Thread definition
DieterGraef 0:f9b6112278fe 78 extern void thread_sample (void const *argument); // function prototype
DieterGraef 0:f9b6112278fe 79 osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
DieterGraef 0:f9b6112278fe 80
DieterGraef 0:f9b6112278fe 81 // Pool definition
DieterGraef 0:f9b6112278fe 82 osPoolDef(MyPool, 10, long);
DieterGraef 0:f9b6112278fe 83 \endcode
DieterGraef 0:f9b6112278fe 84
DieterGraef 0:f9b6112278fe 85
DieterGraef 0:f9b6112278fe 86 This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
DieterGraef 0:f9b6112278fe 87 present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
DieterGraef 0:f9b6112278fe 88 used throughout the whole project.
DieterGraef 0:f9b6112278fe 89
DieterGraef 0:f9b6112278fe 90 <i>Example</i>
DieterGraef 0:f9b6112278fe 91 \code
DieterGraef 0:f9b6112278fe 92 #include "osObjects.h" // Definition of the CMSIS-RTOS objects
DieterGraef 0:f9b6112278fe 93 \endcode
DieterGraef 0:f9b6112278fe 94
DieterGraef 0:f9b6112278fe 95 \code
DieterGraef 0:f9b6112278fe 96 #define osObjectExternal // Objects will be defined as external symbols
