System and Thread Viewer
The System and Thread Viewer window shows system state information and running threads for an RTOS application.
Open the window with Debug – OS Support – System and Thread Viewer.
One thread can run in multiple instances. All active threads are listed in this dialog. The System property shows general information about the RTOS configuration. The item Thread Usage shows the number of available and used threads that are currently active.
The Threads property shows details about thread execution, including information about priority, execution state, and stack usage. Threads columns identify:
Where
| ID | Thread index assigned when the thread was started. |
| Name | Name of the thread function. |
| Priority | Current thread priority. |
| State | Current thread state. |
| Delay | Delay timeout value of a thread. |
| Event Value | Event flags set for a thread. |
| Event Mask | Event flags that the thread is waiting for. |
| Stack Usage |
Stack usage of a thread.
If the option Stack usage watermark is enabled in the
file RTX_Conf_CM.c, then the field Stack Usage
shows the current and maximum stack load.
|
Note
- Then Event Viewer provides timing information of the thread activity.
- Refer to Configuration of Thread count and Stack Space for details.
