cc2530按键控制led灯闪烁

以下是使用cc2530芯片和Z-Stack协议栈控制LED灯闪烁的示例代码：

{
  SAMPLEAPP_ENDPOINT,          //  Endpoint
  SAMPLEAPP_PROFID,            //  Profile ID

void SampleApp_Init( byte task_id )
{

  HalLedSet( HAL_LED_1, HAL_LED_MODE_OFF );
}

UINT16 SampleApp_ProcessEvent( byte task_id, UINT16 events )
{
  afIncomingMSGPacket_t *MSGpkt;
  (void)task_id;

  if ( events & SYS_EVENT_MSG )
  {
    MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );
    while ( MSGpkt )
    {
      switch ( MSGpkt->hdr.event )
      {
        case ZDO_STATE_CHANGE:
          SampleApp_HandleZDOMsgs( (zdoIncomingMsg_t *)MSGpkt );
          break;

        case KEY_CHANGE:
          SampleApp_HandleKeys( ((keyChange_t *)MSGpkt)->state, ((keyChange_t *)MSGpkt)->keys );
          break;

        default:
          break;
      }

      osal_msg_deallocate( (uint8 *)MSGpkt );
      MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );
    }

    return ( events ^ SYS_EVENT_MSG );
  }

  return 0;
}

void SampleApp_HandleZDOMsgs( zdoIncomingMsg_t *inMsg )
{
  switch ( inMsg->hdr.event )
  {
    case ZDO_STATE_CHANGE:
      if ( (inMsg->hdr.status == NetworkSecured) ||
           (inMsg->hdr.status == DevConfgured) )
      {
        HalLedSet( HAL_LED_1, HAL_LED_MODE_ON );
      }
      break;

    default:
      break;
  }
}

void SampleApp_HandleKeys( byte shift, byte keys )
{
  if ( keys & HAL_KEY_CODE_TOGGLE )
  {
    uint8 leds = HalLedGet();
    if ( leds & HAL_LED_1 )
    {
      HalLedSet( HAL_LED_1, HAL_LED_MODE_OFF );
    }
    else
    {
      HalLedSet( HAL_LED_1, HAL_LED_MODE_ON );
    }
  }
}

在此示例代码中，使用`SampleApp_HandleKeys`函数处理按键事件。当按下`HAL_KEY_CODE_TOGGLE`按键时，切换LED灯的状态。在`SampleApp_Init`函数中，通过调用`RegisterForKeys`函数注册按键事件。在`SampleApp_HandleZDOMsgs`函数中，当网络安全性被确认或设备被配置时，LED灯会闪烁。

请注意，此示例代码需要与Z-Stack协议栈一起使用，以便在cc2530芯片上运行。
