Zigbee任务间传递数据

1.定义任务间传递数据的结构体

typedef struct
{
    osal_event_hdr_t hdr;
    uint8 mydata;
}temp_collect_task_msg;
   typedef struct
{
    osal_event_hdr_t hdr;
    uint8 mydata;
}voltage_scan_task_msg;
    typedef struct
{
    osal_event_hdr_t hdr;
    uint8 mydata;
}remote_ctl_temp_task_msg;
typedef struct
{
   osal_event_hdr_t hdr;
   uint8 * mydata;
}light_control_task_msg;

2.在需要执行任务间数据发送的时候执行如下语句

temp_collect_task_msg * Temp_Msg = (temp_collect_task_msg *)osal_msg_allocate(sizeof(temp_collect_task_msg));

remote_ctl_temp_task_msg * Remote_Temp_Msg = (remote_ctl_temp_task_msg *)osal_msg_allocate(sizeof(remote_ctl_temp_task_msg));

light_control_task_msg * light_Msg =(light_control_task_msg*)osal_msg_allocate(sizeof(light_control_task_msg));

Temp_Msg ->hdr.event = ----;
Temp_Msg->mydata = ----;

Remote_Temp_Msg->hdr.event = ----;

Remote_Temp_Msg->mydata = ----;

light_Msg ->hdr.event = ----;

light_Msg ->mydata = ----;

osal_msg_send(Light_Control_TaskID,(uint8 *)Temp_Msg);

osal_msg_send(Light_Control_TaskID,(uint8 *)Remote_Temp_Msg);

osal_msg_send(Light_Control_TaskID,(uint8 *)light_Msg);

3.在任务循环里执行如下语句：

afIncomingMSGPacket_t *MSGpkt;

temp_collect_task_msg * TEMP_Msg;

remote_ctl_temp_task_msg * REMOTE_Temp_Msg;
light_control_task_msg * LIGHT_MSG;

if(events & SYS_EVENT_MSG)
{
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( Light_Control_TaskID );

TEMP_Msg = (temp_collect_task_msg *)MSGpkt;

REMOTE_Temp_Msg = (remote_ctl_temp_task_msg * )MSGpkt;
Light_MSG = (light_control_task_msg *)MSGpkt;

     while ( MSGpkt )
      {
        switch(MSGpkt->hdr.event )
        {

          case AF_INCOMING_MSG_CMD:
               Light_App_ProcessMSGCmd( MSGpkt );
               break;

case ----:

TEMP_Msg->mydata----

break;

case ----:

REMOTE_Temp_Msg->mydata----

break;

case ----:

Light_MSG->mdata----

break;

       osal_msg_deallocate( (uint8 *)MSGpkt );// Release the memory
        MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( Light_Control_TaskID );
      }

      return (events ^ SYS_EVENT_MSG);    // return unprocessed events

}
