//说明:通过队列API传输一个结构体数据

typedef struct AdData_STRUCT
{
     unsigned int xVal;
     unsigned int yVal;
     unsigned int zVal;
}AdData;

#define ADVAL_QUEUE_LEN 10
QueueHandle_t AdValQueue;

//task0 添加结构体数据到队列中去

void ADTask(void const * agrv)

{

AdData AdVal;
//创建一个队列

AdValQueue = xQueueCreate( ADVAL_QUEUE_LEN, sizeof(struct AdData_STRUCT * ));

if( AdValQueue == 0 )
     {
         // Queue was not created and must not be used.
         //创建队列失败

}

for(;;)

{
          struct AdData_STRUCT *pTmp;

          AdVal.xVal = 0;
          AdVal.yVal = 1;
          AdVal.zVal = 2;

          pTmp=&AdVal;//传递地址

          xQueueSend( AdValQueue, (void*)&pTmp, ( TickType_t ) 0);

         osDelay(1000);
     }

}

//task1 接收一个结构体中的数据

void StartDefaultTask(void const * argument)

{

       for(;;)
     {
          struct AdData_STRUCT *pTmp;

          if( AdValQueue != 0 )
          {
               // Receive a message on the created queue. Block for 10 ticks if a
               // message is not immediately available.
               if( xQueueReceive( AdValQueue, &pTmp, ( TickType_t )10 ))
               {
                    printf("%u %u %u\r\n",pTmp->xVal,pTmp->yVal,pTmp->zVal);
               }
          }
osDelay(1000);
     }
     }

}
