The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
|
| PA |
0:7ae810ca8a42
|
23
|
Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
|
| PA |
0:7ae810ca8a42
|
24
|
its implementation.
|
| PA |
0:7ae810ca8a42
|
25
|
|
| PA |
0:7ae810ca8a42
|
26
|
The file cmsis_os.h contains:
|
| PA |
0:7ae810ca8a42
|
27
|
- CMSIS-RTOS API function definitions
|
| PA |
0:7ae810ca8a42
|
28
|
- struct definitions for parameters and return types
|
| PA |
0:7ae810ca8a42
|
29
|
- status and priority values used by CMSIS-RTOS API functions
|
| PA |
0:7ae810ca8a42
|
30
|
- macros for defining threads and other kernel objects
|
| PA |
0:7ae810ca8a42
|

<b>Name conventions and header file modifications</b>
|
| PA |
0:7ae810ca8a42
|
34
|
|
| PA |
0:7ae810ca8a42
|
35
|
All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
|
| PA |
0:7ae810ca8a42
|
36
|
Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
|
| PA |
0:7ae810ca8a42
|
37
|
All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
|
| PA |
0:7ae810ca8a42
|
38
|
|
| PA |
0:7ae810ca8a42
|
39
|
Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
|
| PA |
0:7ae810ca8a42
|
40
|
These definitions can be specific to the underlying RTOS kernel.
|
| PA |
0:7ae810ca8a42
|
41
|
|
| PA |
0:7ae810ca8a42
|
42
|
Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
|
| PA |
0:7ae810ca8a42
|
43
|
compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
|
| PA |
0:7ae810ca8a42
|

<b>Function calls from interrupt service routines</b>
|
| PA |
0:7ae810ca8a42
|
47
|
|
| PA |
0:7ae810ca8a42
|
48
|
The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
|
| PA |
0:7ae810ca8a42
|
49
|
- \ref osSignalSet
|
| PA |
0:7ae810ca8a42
|
50
|
- \ref osSemaphoreRelease
|
| PA |
0:7ae810ca8a42
|
51
|
- \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
|
| PA |
0:7ae810ca8a42
|
52
|
- \ref osMessagePut, \ref osMessageGet
|
| PA |
0:7ae810ca8a42
|
53
|
- \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
|
| PA |
0:7ae810ca8a42
|
54
|
|
| PA |
0:7ae810ca8a42
|
55
|
Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
|
| PA |
0:7ae810ca8a42
|
56
|
from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
|
| PA |
0:7ae810ca8a42
|
57
|
|
| PA |
0:7ae810ca8a42
|
58
|
Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
|
| PA |
0:7ae810ca8a42
|
59
|
If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.

With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file

This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
|
| PA |
0:7ae810ca8a42
|
81
|
present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
|
| PA |
0:7ae810ca8a42
|
82
|
used throughout the whole project.
