CANoe学习笔记-第十章节-Panel实例

1.前期准备工作

1.1首先创建三个节点

1.2 添加相关的系统变量如下

1.3 新建如下dbc文件

1.4 按照书中的要求，新建Panel面板

2.三个节点的程序分别为

2.1 Engine 节点程序

//Engine Node CAPL Program
    includes
    {
      
    }

    variables
    {
      
    }
    //处理系统变量-sysvar::Engine::EngineStateSwitch
    on sysvar sysvar::Engine::EngineStateSwitch
    {
     $EngineState::OnOff = @this;
      if(@this)
        $EngineState::EngineSpeed = @sysvar::Engine::EngineSpeedEntry;
      else
        $EngineState::EngineSpeed = 0;
    }

    //process the change event of sysvar::Engine::EngineSpeedEntry
    on sysvar sysvar::Engine::EngineSpeedEntry
    {
      if(@sysvar::Engine::EngineStateSwitch) 
      {
        $EngineState::EngineSpeed = @this;
      }
    }

2.2 Door 节点程序

//Door Node CAPL Program
    includes
    {
      
    }

    variables
    {
      int gDebugCounterTX = 0;
      int gDebugCounterTXRQ = 0;
      int gDebugCounterRX = 0;
      
    }

    on start
    {
       setWriteDbgLevel(0); // set DbgLevel = 1 to get more information in Write-Window
    }
    
    //check DoorState transmission direction
    on message DoorState 
    {
      //Check DoorState Message transmission direction - TX
      if (this.dir == TX)
      {
        gDebugCounterTX++;
        if(gDebugCounterTX == 10)
        {
          writeDbgLevel(1,"DoorState TX received by node %NODE_NAME%");
          gDebugCounterTX = 0;
        }     
      }
      //Check DoorState Message transmission direction - TXREQUEST
      if(this.dir == TXREQUEST)
      {
        gDebugCounterTXRQ++;
        if(gDebugCounterTXRQ == 10)
        {
          writeDbgLevel(1,"DoorState TXREQUEST received by node %NODE_NAME%");
          gDebugCounterTXRQ = 0;
        } 
      }
      //Check DoorState Message transmission direction - RX
      if (this.dir == RX)
      {
        gDebugCounterRX++;
        if(gDebugCounterRX == 10)
        {
          writeDbgLevel(1,"Error: DoorState RX received by node %NODE_NAME%");
          gDebugCounterRX = 0;
        }
      }
    }    
    
    //to disable the debug info output
    on key '0'
    {
      setwriteDbgLevel(0);
    }
    
    //to enable the debug info output
    on key '1'
    {
      setwriteDbgLevel(1);
    }

2.3 Display 节点程序

//Display Node CAPL Program
    includes
    {
      
    }

    variables
    {
      
    }

    //process the EngineState Message received
    on message EngineState 
    {  
      // engine state received
      if (this.dir == RX)
      {
        @sysvar::Engine::EngineSpeedDspMeter = this.EngineSpeed / 1000.0;
      }
    }
    
    //process the DoorState Message received
     on message DoorState 
    {  
      // door state received
      if (this.dir == RX)
      {
          @EnvDoorState = this.Door_L + this.Door_R * 2;
      }
    }
