A helper API for Task creation for the user domain and also a wrapper module for the task creation functions of FreeRTOS.

This module is used to control and limit the use of task creation by the user so to accommodate easy backward compatibility in the future.

  • This module is limited to when the RTOS Scheduler is not running

Functions#

ReturnCode_t
ZW_UserTask_Init(void)

Initializes this module.

ReturnCode_t
ZW_UserTask_CreateTask(ZW_UserTask_t *task, TaskHandle_t *xHandle)

Used to create user application level tasks.

bool
ZW_UserTask_ApplicationRegisterTask(void(*appTaskFunc)(SApplicationHandles *), uint8_t iZwRxQueueTaskNotificationBitNumber, uint8_t iZwCommandStatusQueueTaskNotificationBitNumber, const SProtocolConfig_t *pProtocolConfig)

Used to create the main application task at highest UserTask priority.

Enumeration Documentation#

ZW_UserTask_Priority_t#

ZW_UserTask_Priority_t
Enumerator
USERTASK_PRIORITY_BACKGROUND

Right above idle priority. Good for HMI and worker threads.

USERTASK_PRIORITY_NORMAL

The default 'APP'-task priority.

USERTASK_PRIORITY_HIGHEST

High priority UserTask. Good for handling interrupts requests.

ReturnCode_t#

ReturnCode_t

Return code used by the functions in this module.

Enumerator
Code_Success

Success.

Code_Fail_Unknown

Default failed code with no helping indication.

Code_Fail_NoMemory

Failed due to lack of memory.

Code_Fail_LimitReached

A set limit is reached for this operation.

Code_Fail_NotFound

A specific entity could not be found.

Code_Fail_Suspended

The operation or the entire module is globally suspended and cannot be utilized at this point in time.

Code_Fail_InvalidState

Not in an appropriate state for this call.

Code_Fail_InvalidOperation

This operation can not be allowed at this point.

Code_Fail_InvalidParameter

Wrong/invalid input parameters.

Code_DependencyUnavailable

A required resource or dependency that this operation relies on was not setup or available. Perhaps wrong initialization order.

Code_Fail_Busy

A resource needed by this operation or call is busy. Try again later. Potential racing condition or untimely action.

Code_Fail_Timeout

Failed due to timeout.

Code_Fail_Driver

Error occurred at the driver level.

Code_Fail_NotImplemented

This operation is not supported due to limited implementation or need.

Code_Fail_NotAllowed

This operation cannot be performed, since it is blocked or not allowed.

Function Documentation#

ZW_UserTask_Init#

ReturnCode_t ZW_UserTask_Init (void )

Initializes this module.

Parameters
N/A

  • Should not be used directly.

Return Returns ReturnCode_t. See Also

ZW_UserTask_CreateTask#

ReturnCode_t ZW_UserTask_CreateTask (ZW_UserTask_t * task, TaskHandle_t * xHandle)

Used to create user application level tasks.

Parameters
[out]task

Used to return the task handle. Can be NULL Return Returns ReturnCode_t. See ReturnCode_t for more info.

N/AxHandle

ZW_UserTask_ApplicationRegisterTask#

bool ZW_UserTask_ApplicationRegisterTask (void(*)(SApplicationHandles *) appTaskFunc, uint8_t iZwRxQueueTaskNotificationBitNumber, uint8_t iZwCommandStatusQueueTaskNotificationBitNumber, const SProtocolConfig_t * pProtocolConfig)

Used to create the main application task at highest UserTask priority.

Parameters
N/AappTaskFunc

Application task that will be triggered by FreeRTOS. (function pointer)

N/AiZwRxQueueTaskNotificationBitNumber

The bit number set by Protocol when a message has been put on the ZW Rx queue. (Receiving EAPPLICATIONEVENT_ZWRX events)

N/AiZwCommandStatusQueueTaskNotificationBitNumber

The bit number Set by Protocol when a message has been put on the ZW command status queue. (Receiving EAPPLICATIONEVENT_ZWCOMMANDSTATUS events)

N/ApProtocolConfig

Pointer to a statically allocated Protocol Config structure.

This function further registers Queue Notification Bit Numbers so that an association is created between the bit number and the event handle to invoke for that event, when it occurs.

This function should only be called once, or false is returned

  • This task is the only UserTask that should use the ZAF API functions. Accessing the ZAF API functions from any other ZW_UserTask.h generated tasks will lead to undefined behavior

Returns

  • true if the main APP task was created successfully, false if not.
