Description

Function Documentation

void EvrRtxTimerError ( osTimerId_t  timer_id,
int32_t  status 
)
Parameters
[in]timer_idtimer ID obtained by osTimerNew or NULL when ID is unknown.
[in]statusextended execution status.

The event TimerError is generated when Timer Management routines complete their execution due to an error.

The status parameter indicates the execution status and can be one of the osStatus_t codes or one of the extended execution status codes which are summarized in the table below.

Extended Status Code Description
osRtxErrorKernelNotReady Kernel scheduler is not in Ready state.
osRtxErrorKernelNotRunning Kernel scheduler is not executing - there is no running thread.
osRtxErrorInvalidControlBlock Object control block with invalid alignment or size was specified.
osRtxErrorInvalidDataMemory Object data memory with invalid alignment or size was specified.
osRtxErrorInvalidThreadStack Thread stack memory with invalid alignment or size was specified.
osRtxErrorInvalidPriority Invalid thread priority was specified.
osRtxErrorThreadNotJoinable Specified thread is not joinable.
osRtxErrorMutexNotOwned Specified mutex is not owned by the current running thread.
osRtxErrorMutexNotLocked Specified mutex is not locked.
osRtxErrorMutexLockLimit Maximum number of recursive mutex locks reached.
osRtxErrorSemaphoreCountLimit Semaphore count limit reached.
osRtxErrorTZ_InitContext_S Secure context memory system initialization failed.
osRtxErrorTZ_AllocContext_S Secure context memory allocation failed.
osRtxErrorTZ_FreeContext_S Secure context memory deallocation failed.
osRtxErrorTZ_LoadContext_S Secure context load failed.
osRtxErrorTZ_SaveContext_S Secure context save failed.

Value in the Event Recorder shows:

  • timer_id : timer ID.
  • status : execution status code.
void EvrRtxTimerCallback ( osTimerFunc_t  func,
void *  argument 
)
Parameters
[in]funcstart address of a timer call back function.
[in]argumentargument to the timer call back function.

The event TimerCallback is generated when the timer callback function is called.

Value in the Event Recorder shows:

  • func : start address of a timer call back function.
  • argument : memory address of argument to the timer call back function.
void EvrRtxTimerNew ( osTimerFunc_t  func,
osTimerType_t  type,
void *  argument,
const osTimerAttr_t *  attr 
)
Parameters
[in]funcstart address of a timer call back function.
[in]typeosTimerOnce for one-shot or osTimerPeriodic for periodic behavior.
[in]argumentargument to the timer call back function.
[in]attrtimer attributes.

The event TimerNew is generated when the function osTimerNew is called.

Value in the Event Recorder shows:

  • func : start address of a timer call back function.
  • type : timer type: osTimerOnce for one-shot or osTimerPeriodic for periodic behavior.
  • argument : memory address of argument to the timer call back function.
  • attr : memory address of Timer attributes or 0 when they are not specified.

In case when timer attributes are provided in the API call they are also detailed in the Event Recorder.

void EvrRtxTimerCreated ( osTimerId_t  timer_id,
const char *  name 
)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.
[in]namepointer to timer object name.

The event TimerCreated is generated when the function osTimerNew successfully creates a timer object.

Value in the Event Recorder shows:

  • timer_id : timer ID.
void EvrRtxTimerGetName ( osTimerId_t  timer_id,
const char *  name 
)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.
[in]namepointer to timer object name.

The event TimerGetName is generated when the function osTimerGetName is called and its execution result is known.

Value in the Event Recorder shows:

  • timer_id : timer ID.
  • name : retrieved memory address of name string (0 in case of a failure).
void EvrRtxTimerStart ( osTimerId_t  timer_id,
uint32_t  ticks 
)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.
[in]tickstime ticks value of the timer.

The event TimerStart is generated when the function osTimerStart is called.

Value in the Event Recorder shows:

  • timer_id : timer ID.
  • ticks : time ticks value of the timer.
void EvrRtxTimerStarted ( osTimerId_t  timer_id)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.

The event TimerStarted is generated when the function osTimerStart successfully starts or restarts the timer operation.

Value in the Event Recorder shows:

  • timer_id : timer ID.
void EvrRtxTimerStop ( osTimerId_t  timer_id)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.

The event TimerStop is generated when the function osTimerStop is called.

Value in the Event Recorder shows:

  • timer_id : timer ID.
void EvrRtxTimerStopped ( osTimerId_t  timer_id)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.

The event TimerStopped is generated when the function osTimerStop successfully stops the timer operation.

Value in the Event Recorder shows:

  • timer_id : timer ID.
void EvrRtxTimerIsRunning ( osTimerId_t  timer_id,
uint32_t  running 
)
Parameters
[in]timer_idtimer ID obtained by osTimerNew.
[in]runningrunning state: 0 not running, 1 running.

The event TimerIsRunning is generated when the function osTimerIsRunning is called and its execution result is known.

Value in the Event Recorder shows:

  • timer_id : timer ID.
  • running : timer running state: 0 not running, 1 running.
void EvrRtxTimerDelete ( osTimerId_t  timer_id)
Parameters
