Comm.PutPointer Data(FinalWrite Param,4);

}

}

I have:

jComboBox1.setM odel(new javax.swing.Def aultComboBoxMod el(new String[] {\"30\", \"50\" }));

i get nex error:

java.lang.Array IndexOutOfBound sException

Hove must i configure argument for WriteParamToPic ?

I have trayed to change number of arrays in WriteParamToPic, but it returns me other errors.

Thank you

FinalWriteParam[i] = (byte) WriteParam[i];
At this point WriteParam is longer than FinalWriteParam because

Code:

WriteParam = ParamIn.toCharArray();

is returning an Array os size bigger than 4. You have to decide what you want to do with the surplus bits first to solve that problem

Thank you wery much.I don't get error any more.

But now, I’ll gone to tray to explain next problem. And if we well resolve it, I’ll
be much closer to my final faculty work.

I'm sending data (parameters) to the PIC microcontroller . I have made application for regulation of temperature. And to control and supervise it i need to use a graphic interface. So, from Hyper terminal i can do it wery well.
My PIC understands characters sent from keyboard one by one.

But in my Java work:...
my code doesn’t accurate me valid transmission. I have to press (activate transmission) on button several time to get result and much time the transferred data isn’t correct. I'll appreciate every suggestions because i assume that them well lead me to conclusion have to resolve communication problem.

Now when I think. I have programmed microcontroller to activate interrupt itch time it gets data (one character)on him input. So it could be resolution to include a delay between sending of
characters to give microcontroller time to elaborate data.
Yes , I think this could be wright way. So if I resume I have to send character by character and to include minimum delay between itch transmission.Wr ight?

To continue before sent code:

Code:

 void PutPointerData(byte [] ChIn, int ChNumb) 
{
try 
{
OutStream.write(ChIn,0,ChNumb);
OutStream.flush();
} catch (IOException ex) 
{
ex.printStackTrace();
}
}

**ivannavi** · Feb 14 '07, 01:26 PM

And now i have a concrete problem:

Code:

public static void WriteParamToPic(String ParamIn)
    {
        char [] WriteParam = new char[4];       
        WriteParam =ParamIn.toCharArray();
        for(int i=0; i<4; i++){            
          Comm.PutData((byte) WriteParam[i]) ;
        }
    }

 //  to send induvidual character
 void PutData (byte ChIn)	    
            {
                try {
                    OutStream.write((byte) ChIn);
                    OutStream.flush();
                    } catch (IOException ex) 
                    {
                    ex.printStackTrace();
                    }
            }

I can't test my code because i need a delay between itch sending.
So I have tray at next way:
I think that from the code can be ungderstud that i would like to make a delay betwen induidual sending, but like you my see i realy need help.

Code:

public static void WriteParamToPic(String ParamIn)
    {
        char [] WriteParam = new char[4];       
        WriteParam =ParamIn.toCharArray();
        for(int i=0; i<4; i++){
         Comm.charTimer();        //eror:create a metod charTimer() in     testcomm.TwoWaySerialComm
         Comm.PutData((byte)  WriteParam[i]) ;
        }
       
    }
   
    private  void charTimer() 
    {
	 charTmr = new Timer();
        charTmr.schedule(doNothing,1000);  //error:create fild doNothing
    }

You can use the Thread.sleep method

               }
        }
       
    }

In this way it works.
Thank you wery much.

Anytime. Notice also that I did not really give you much help here. Just a few comments and you managed to fix the problem yourself. It's always a pleasure assisting those who prefer to write their own code themselves.

**ivannavi** · Feb 15 '07, 01:04 PM

Code:

   private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    
        
        if(testcomm.TestForm.mainTmr != null)
           testcomm.TestForm.mainTmr.cancel();      
        
     //other code  

        testcomm.TestForm.startTimer() ;
        // non static metod cannot be referenced from static contrxt
    }

And timer:

Code:

public  void startTimer() 
    {
	mainTmr = new Timer();
        mainTmr.schedule((new TimerChhRunCls()),1000,timeSampleLong);
    }
    class TimerChhRunCls extends TimerTask 
    {
        public void run() 
        {
            ReadTemperatureFromRS232();
        }
        
    }

Sure, that with yours help it can do more.

My school work is done, but I wont to improve(make beater) it, that it can be used in technical application

for real. So, there is some more work to do.

I have to stop timer and activate it again after other code (data transmission) has been done.

But I get error (comment). What must i do to resolve it? A must admit that theory about static and non static isn't steal clear to me.

What error(comment) are you getting.

**ivannavi** · Feb 15 '07, 04:25 PM

// non static metod cannot be referenced from static context

and it referes to next line of code:
testcomm.TestFo rm.startTimer() ;

it is part of first block of code in previous post.

Thank you

This may really depend on how you designed your classes, but
what happens if you make the startTimer method static?

**ivannavi** · Feb 15 '07, 05:01 PM

First i have changed metod to static and then variable timeSampleLong too.
But i could not resolve next error :
"non-static variable this couldnot be referenced from a static context"
which refers to:
mainTmr.schedul e((new TimerChhRunCls( )),1000,timeSam pleLong);
