That code looks like somebody was testing certain values.

Maybe try the following code, it has not been tested by me and might need some corrections:

Code: [Select]

    Dim Delta As Integer
    Dim Last_Angle As Integer = 360
    Dim Total_Turns As Single

    Private Sub RotationalIndicator1_ValueChanged(sender As Object, e As EventArgs) Handles RotationalIndicator1.ValueChanged
        Dim Current_Angle As Integer = RotationalIndicator1.Value

        '* Determine Delta (CW or CCW)
        If Current_Angle > 180 AndAlso Last_Angle = 360 Then
            Delta = Last_Angle - Current_Angle
        ElseIf Current_Angle <= 180 AndAlso Last_Angle = 360 Then
            Delta = Current_Angle
        Else
            Delta = Current_Angle - Last_Angle
        End If

        Total_Turns = Total_Turns + ( Delta / 360 )

        RotationalIndicator1.Text = Total_Turns.ToString("0.0")

        If Current_Angle = 0 Then
            Last_Angle = 360
        Else
            Last_Angle = Current_Angle
        End If
    End Sub


I tried this and seems working but because I don't have the compass with me, I can't tell whether it is 100% working. my only concern is the indicator will not display 360, after 359, it will be 0 again. so, I can't tell if the code is fully correct until I got the physical compass later.

how to convert this to vb.net please?
it looks like C# and I used the converter but no luck.

Code: [Select]

int Start_Angle;    // The first compass reading to mark our beginning rotation.
                    // signed int, will range 0 to 359
int Last_Angle;     // preserve the value of the last reading.
                    // signed int, will range 0 to 359
int Current_Angle;  // computed position for where we are now.
                    // signed int, will range -720 to +720

void Init_Rotation(int Current_Pos);
void Get_Rotation(int Current_Pos);
                                   
void main(void)
{
  Init_Rotation(10);
  Get_Rotation(20);
 
  Init_Rotation(10);
  Get_Rotation(350);
 
  Init_Rotation(90);
  Get_Rotation(271);
 
  Init_Rotation(20);
  Get_Rotation(10); 
 
  Init_Rotation(350);
  Get_Rotation(10); 
 
  Init_Rotation(271);
  Get_Rotation(90); 
}

void Init_Rotation(int Current_Pos)
{
  // set Start_Angle, Last_Angle,
  // and Current_Angle to the current reading
  Current_Angle = Last_Angle = Start_Angle = Current_Pos;   
}

void Get_Rotation(int Current_Pos)
{
  // will take the current reading,
  // compute the Current_Angle,
  // then update Last_Angle, and Current_Angle
  int Delta;
 
  // compute delta angle
  Delta = Current_Pos - Last_Angle;
 
  // put Delta into range of
  // -180 <= angle <= 180
  if (Delta > 180) Delta -= 360;
  if (Delta < -180) Delta += 360;
 
  // update Current_Angle
  Current_Angle += Delta;
 
  // update last reading with our current reading
  Last_Angle = Current_Pos;   
}
my main problem is that I don't quite understand this part:

Code: [Select]

void main(void)
{
  Init_Rotation(10);
  Get_Rotation(20);
 
  Init_Rotation(10);
  Get_Rotation(350);
 
  Init_Rotation(90);
  Get_Rotation(271);
 
  Init_Rotation(20);
  Get_Rotation(10); 
 
  Init_Rotation(350);
  Get_Rotation(10); 
 
  Init_Rotation(271);
  Get_Rotation(90); 
}
what is does actually?

I have tried that but that only true if the direction starts from 0,1,2,3.... 359
what if it starts like this, 0,359,358,357,356....1?

also if the value pass trough 0 again, then the no. of turn will turn back to zero.

Hi All,

I want to do a counting on number of turn on the rotational indicator on both direction.
For example, if my arrow has made twice clockwise turn, it will show 2 on my apps.
same for CCW. How can I do that on VB.net for this control?

Hi, I need to start the app from a different page. but the drop down menu only shows MainForm.
Can someone help please. Also I got this message at the Compile section:
An error occurred trying to load the page.
Object reference not set to an instance of an object.
is it meant to be like that?

« on: August 27, 2020, 06:37:59 AM »

Hi All,

I'd like to hear you guys experience regarding the use of this driver.
I'm using a Omron CJ2M with 9600 7 2 E setting using RS232.

So far it works only that the response is a bit slow sometimes it could take up to 3 second to see a change on the HMI. attached is the screenshot.

i guess i have same issue with this guy: https://www.advancedhmi.com/forum/index.php?topic=2763.0

i'm not sure if the whole tab page is updating at the same time. if yes, can someone tell me how to stop updating the hidden tab page?

Tips & Tricks / Analog cylinder

« on: August 27, 2020, 04:17:14 AM »

this is an option to escape the problem with the current analog cylinder issue: https://www.advancedhmi.com/forum/index.php?topic=2572.msg15477#msg15477

1. create a cylinder housing using a picturebox. you can set background image to represent a cylinder housing.
2. create a cylinder rod using BarLevel. set show value to False. Play around with properties to get your desired display. set the FillDirection to represent the in/out movement of the rod.

you can create vertical and horizontal cylinder with this easily.
