Macro Definition Documentation

◆ OS_IDLE_TASK_STACK_SIZE

#define OS_IDLE_TASK_STACK_SIZE   configMINIMAL_STACK_SIZE

stack size of the idle task

Definition at line 62 of file os.c.

Function Documentation

◆ OS_DelayTask()

void OS_DelayTask ( uint32_t  delay_ms)

Delays a task in milliseconds.

TODO

Parameters
delay_mstime delay value

Definition at line 186 of file os.c.

◆ OS_DelayTaskUntil()

void OS_DelayTaskUntil ( uint32_t *  pPreviousWakeTime,
uint32_t  milliseconds 
)

Delay a task until a specified time.

TODO

Parameters
pPreviousWakeTimePointer to a variable that holds the time at which the task was last unblocked. PreviousWakeTime must be initialized with the current time prior to its first use (PreviousWakeTime = OS_osSysTick()).
millisecondstime delay value in milliseconds

Definition at line 196 of file os.c.

◆ OS_EnterTaskCritical()

void OS_EnterTaskCritical ( void  )

Enter Critical interface function for use in FreeRTOS-Tasks and FreeRTOS-ISR.

checks the function context (task/thread mode or interrupt (handler) mode) and calls the corresponding enter-critical function

Definition at line 174 of file os.c.

◆ OS_ExitTaskCritical()

void OS_ExitTaskCritical ( void  )

Exit Critical interface function for use in FreeRTOS-Tasks and FreeRTOS-ISR.

Checks the function context (task/thread mode or interrupt (handler) mode) and calls the corresponding exit-critical function

Definition at line 178 of file os.c.

◆ OS_GetTickCount()

uint32_t OS_GetTickCount ( void  )

Returns OS based system tick value.

TODO

Returns
time stamp in milliseconds, based on the operating system time.

Definition at line 182 of file os.c.

◆ OS_InitializeOperatingSystem()

void OS_InitializeOperatingSystem ( void  )

Initialization the RTOS interface.

This function initializes the mutexes, eventgroups and tasks.

Definition at line 104 of file os.c.

Here is the call graph for this function:

◆ OS_StartScheduler()

void OS_StartScheduler ( void  )

Starts the operating system scheduler.

Definition at line 100 of file os.c.

◆ OS_SystemTickHandler()

void OS_SystemTickHandler ( void  )

Handles the tick increment of operating systick timer.

TODO

Definition at line 206 of file os.c.

◆ OS_TriggerTimer()

void OS_TriggerTimer ( volatile OS_TIMER_s timer)

Increments the system timer os_timer.

The os_timer is a runtime-counter, counting the time since the last reset.

Parameters
timerTODO

Definition at line 141 of file os.c.

◆ vApplicationGetIdleTaskMemory()

void vApplicationGetIdleTaskMemory ( StaticTask_t **  ppxIdleTaskTCBBuffer,
StackType_t **  ppxIdleTaskStackBuffer,
uint32_t *  pulIdleTaskStackSize 
)

Supplies the memory for the idle task.

This is needed due to the usage of configSUPPORT_STATIC_ALLOCATION. This is an FreeRTOS function an does not adhere to foxBMS function naming convetions.

Parameters
ppxIdleTaskTCBBufferTODO
ppxIdleTaskStackBufferTODO
pulIdleTaskStackSizeTODO

Definition at line 113 of file os.c.

◆ vApplicationIdleHook()

void vApplicationIdleHook ( void  )

Hook function for the idle task.

This is an FreeRTOS function an does not adhere to foxBMS function naming convetions

Definition at line 133 of file os.c.

Here is the call graph for this function:

◆ vApplicationStackOverflowHook()

void vApplicationStackOverflowHook ( TaskHandle_t  xTask,
char *  pcTaskName 
)

Hook function for StackOverflowHandling.

This handler is used when the operation system encounters a stackoverflow in a task. This is an FreeRTOS function an does not adhere to foxBMS function naming convetions

Parameters
xTaskTODO
pcTaskNameTODO

Definition at line 137 of file os.c.
