Function Documentation

void isf_init_task ( uint32 initial_data )

This function initializes the ISF components for operation.

Purpose:: The ISF initialization task calls each ISF component to perform a one-time initialization. Each ISF component executes its initialization routine, if enabled in isf_user_config.h and if there are any initialization activities to perform.

Parameters:

[in] initial_data This is required by MQX and any UINT32 value can be used.

Returns:: This function does not return any values.

Constraints:: (1) The isf_init_task() must be the highest priority task in the system.
(2) This API call must be invoked only once and must run before any other task in the system runs. This can be ensured by using the default setting in isf_init.h, which sets this task as the highest priority task in the system.
Once initialization is complete, the task exits and its task memory is reclaimed by the system and is made available for application use.

Reentrant: No

Link Libraries:: isf_core.lib

Definition at line 60 of file isf_init.c.

References isf_lib_init().

isf_status_t isf_lib_init ( void * pOptions )

This function initializes the ISF library.

Purpose:: The isf_lib_init() function is called by an application to initialize the ISF library.
Note: This initialization must be done in the user application before it calls any ISF function.

Parameters:

[in] pOptions This must be a NULL pointer.

Returns:: isf_lib_init() returns a value of type isf_status_t indicating the result of the operation.

Return values:

ISF_SUCCESS	is returned when the library initializes successfully.
ISF_ERR_LIB_INIT	is returned when the library does not initialize successfully.

Reentrant: No

Link Libraries:: None.

This function initializes the ISF library.

API ISF library get information.

void isf_system_sync ( void )

This function synchronizes the user tasks and the system initialization.

Purpose:: This function blocks the user tasks from executing until ISF initialization is completed.

Returns:: This function does not return any values.

Constraints:

Reentrant: No
