| emilmont | 6:350b53afb889 | 26 | \page cmsis_os_h Header File Template: cmsis_os.h |
| emilmont | 6:350b53afb889 | 27 | |
| emilmont | 6:350b53afb889 | 28 | The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS). |
| emilmont | 6:350b53afb889 | 29 | Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents |
| emilmont | 6:350b53afb889 | 30 | its implementation. |
| emilmont | 6:350b53afb889 | 31 | |
| emilmont | 6:350b53afb889 | 32 | The file cmsis_os.h contains: |
| emilmont | 6:350b53afb889 | 33 | - CMSIS-RTOS API function definitions |
| emilmont | 6:350b53afb889 | 34 | - struct definitions for parameters and return types |
| emilmont | 6:350b53afb889 | 35 | - status and priority values used by CMSIS-RTOS API functions |
| emilmont | 6:350b53afb889 | 36 | - macros for defining threads and other kernel objects |
| emilmont | 6:350b53afb889 | 37 | |
| emilmont | 6:350b53afb889 | 38 | |
| emilmont | 6:350b53afb889 | 39 | <b>Name conventions and header file modifications</b> |
| emilmont | 6:350b53afb889 | 40 | |
| emilmont | 6:350b53afb889 | 41 | All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions. |
| emilmont | 6:350b53afb889 | 42 | Definitions that are prefixed \b os_ are not used in the application code but local to this header file. |
| emilmont | 6:350b53afb889 | 43 | All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread. |
| emilmont | 6:350b53afb889 | 44 | |
| emilmont | 6:350b53afb889 | 45 | Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation. |
| emilmont | 6:350b53afb889 | 46 | These definitions can be specific to the underlying RTOS kernel. |
| emilmont | 6:350b53afb889 | 47 | |
| emilmont | 6:350b53afb889 | 48 | Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer |
| emilmont | 6:350b53afb889 | 49 | compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation. |
| emilmont | 6:350b53afb889 | 50 | |
| emilmont | 6:350b53afb889 | 51 | |
| emilmont | 6:350b53afb889 | 52 | <b>Function calls from interrupt service routines</b> |
| emilmont | 6:350b53afb889 | 53 | |
| emilmont | 6:350b53afb889 | 54 | The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR): |
| emilmont | 6:350b53afb889 | 55 | - \ref osSignalSet |
| emilmont | 6:350b53afb889 | 56 | - \ref osSemaphoreRelease |
| emilmont | 6:350b53afb889 | 57 | - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree |
| emilmont | 6:350b53afb889 | 58 | - \ref osMessagePut, \ref osMessageGet |
| emilmont | 6:350b53afb889 | 59 | - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree |
| emilmont | 6:350b53afb889 | 60 | |
| emilmont | 6:350b53afb889 | 61 | Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called |
| emilmont | 6:350b53afb889 | 62 | from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector. |
| emilmont | 6:350b53afb889 | 63 | |
| emilmont | 6:350b53afb889 | 64 | Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time. |
| emilmont | 6:350b53afb889 | 65 | If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive. |
| emilmont | 6:350b53afb889 | 66 | |
| emilmont | 6:350b53afb889 | 67 | |
| emilmont | 6:350b53afb889 | 68 | <b>Define and reference object definitions</b> |
| emilmont | 6:350b53afb889 | 69 | |
| emilmont | 6:350b53afb889 | 70 | With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file |
| emilmont | 6:350b53afb889 | 71 | that is used throughout a project as shown below: |
| emilmont | 6:350b53afb889 | 72 | |
| emilmont | 6:350b53afb889 | 73 | <i>Header File</i> |
| emilmont | 6:350b53afb889 | 74 | \code |
| emilmont | 6:350b53afb889 | 75 | #include <cmsis_os.h> // CMSIS RTOS header file |
| emilmont | 6:350b53afb889 | 76 | |
| emilmont | 6:350b53afb889 | 77 | // Thread definition |
| emilmont | 6:350b53afb889 | 78 | extern void thread_sample (void const *argument); // function prototype |
| emilmont | 6:350b53afb889 | 79 | osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100); |
| emilmont | 6:350b53afb889 | 80 | |
| emilmont | 6:350b53afb889 | 81 | // Pool definition |
| emilmont | 6:350b53afb889 | 82 | osPoolDef(MyPool, 10, long); |
| emilmont | 6:350b53afb889 | 83 | \endcode |
| emilmont | 6:350b53afb889 | 84 | |
| emilmont | 6:350b53afb889 | 85 | |
| emilmont | 6:350b53afb889 | 86 | This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is |
| emilmont | 6:350b53afb889 | 87 | present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be |
| emilmont | 6:350b53afb889 | 88 | used throughout the whole project. |
| emilmont | 6:350b53afb889 | 89 | |
| emilmont | 6:350b53afb889 | 90 | <i>Example</i> |
| emilmont | 6:350b53afb889 | 91 | \code |
| emilmont | 6:350b53afb889 | 92 | #include "osObjects.h" // Definition of the CMSIS-RTOS objects |
| emilmont | 6:350b53afb889 | 93 | \endcode |
| emilmont | 6:350b53afb889 | 94 | |
| emilmont | 6:350b53afb889 | 95 | \code |
| emilmont | 6:350b53afb889 | 96 | #define osObjectExternal // Objects will be defined as external symbols |
| emilmont | 6:350b53afb889 | 97 | #include "osObjects.h" // Reference to the CMSIS-RTOS objects |
| emilmont | 6:350b53afb889 | 98 | \endcode |
