Z-Stack Structure

Contents Start with the main function. osal_init_system() osalAddTask() osalInitTasks() Define Simple Descriptor Task Init function Task Event processing function

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

osal_init_system() Task initialize

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

osalAddTask()

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

osalTaskInit() User Task ZigBee Task

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

osalTaskAdd Create a new Task Control Block

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

osalInitTasks Call every init function on each task added

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

SerialApp_init() We are using “Service Discovery”

Flow chart osal_init_system() osalTaskInit() osalAddTasks() osalInitTasks() osal_start_system() osalTaskAdd (MAC…) osalTaskAdd (NWK…) osalTaskAdd (USER…) SerialApp_Init() SerialApp_ProcessEvent() MAIN()

SerialApp_ProcessEvent()(1) Use a system event to process ZigBee packets

SerialApp_ProcessEvent()(2) We can also use user-defined events

Sending data to the ZigBee network Code for sending a packet to ZigBee network

Issues We don’t have to write all of these codes. Important to understand how the sending function works Good to know how Z-Stack works.
