SIOC Script for Speed Indicator

[aeromax 10]

Hi

thanks for that

[Aircraft Aviation 2]

Hi Max,

I'm a bit confused at the logic of the script you're using. I personally have not used that logic.

Firstly, is your Airspeed Indicator linear? If so, please post the servo values for the "0" position and the "400" knots position.

If it is non-linear, please post a picture, so I can figure out the "stepping" required for each section.

Regards,

Jack

Hi Dear !. Thanks for fast responding.

[Aircraft Aviation 2]

Hi Max,

When I say linear/non-linear, I am talking about the guage itself.

A linear gauge means that the gaps between each marking are exactly the same. If they are different, it's non-linear.

I shall start writing your script and I will post it here when finished.

ok, i understand it !.

Sorry, but i never used sioc before or something like that !.

If you like a (macro)-picture of speed-indicator dial; i can send it; just let me know, where if have to do that.

thank´s a lot !

Hi Max,

Please try this script:

Var 0002, name IAS_Servo, Link USB_SERVOS, Output 1, PosL 0, PosC 562, PosR 988, Type 2 // IAS Servo Instrument

Var 0001, name IAS, Link FSUIPC_IN, Offset $02BC, Length 4, // IAS from SIM
{
  L0 = DIV &IAS 128     // FSUIPC Conversion Airspeed IAS
  L0 = ABS L0     // L0 not signed 
  L2 = L0    
  IF L0 <= 100     // First sector
  {
    L1 = L2 * 1.27     // (127 steps/100 values) = 1.27
  }
  ELSE     // Is a greater value
  {
    L2 = L0 - 100     //  L2 only have values for next sector
    IF L0 <= 200     // Second sector
    {
      L1 = L2 * 3.69     // (369 steps / 100 values) = 3.69
      L1 = L1 + 127     // Add steps of others sectors (+127)
    }
    ELSE
    {
      L2 = L0 - 200     // L2 only have values for next sector
      IF L0 <= 300     // 3. Sector
      {
        L1 = L2 * 2.94     // ( 294 / 100) = 2.94
        L1 = L1 + 496     // Add steps of others sectors (127 + 369) 
      }
      ELSE     // Out of range
      {
        L2 = L0 - 300     //  L2 only have values for next sector
        IF L0 <= 400     // 4. sector
        {
          L1 = L2 * 1.980     // (198 steps / 100 values) = 1.980
          L1 = L1 + 790     // Add steps of others sectors (127 + 369 + 294)
        }
        ELSE
        {
          L1 = 988         // Max. position of IAS Gauge
        }
      }
    }
  }
  &IAS_Servo = 0 + L1     // Add to minimum (0)
}[/CODE]

It should work, if the values you gave me are correct.

Also, please note, you MUST ensure that your Servo is accurate. Does the servo hit exactly 400 Knots each time you send it the value of 988? Or does it go to 410, or something like that? It MUST be accurate.

Please tell me if the script works.

Kindest regards,

Jack

Yeep.

[Aircraft Aviation 2]

AWESOME ! THAT´s GREAT !!

YES I´LL TRY THAT ONE AND ´LL LET YOU KNOW IF IT WORKS.

PERFECT, THANK YOU SO MUCH !!

No problem Max, I hope it works!

If it doesn't I shall try again for you.

Jack

[aeromax 10]

Superb.

[Aircraft Aviation 2]

Hi Max,

That's great! I'm so glad it worked for you.

To fix the < 100 Knots issue, I will need a picture (any image, doesn't have to be a photo) of your instrument. It sounds like there are some irregular steps between 0 and 100. I will need to adjust the multiplier value.

Kindest regards,

Jack

thanks for that

[Aircraft Aviation 2]

Hi Max,

That really is fantastic news, I'm so happy that I could help. In fact, I hadn't written a Servo script in over a year, so I appreciate the practice!

Did you solve the airspeed problem between 0 and 100 Knots, or wold you like me to re-write that section of the script still?

Kindest regards,

Jack

[aeromax 10]

awesome !!

[Aircraft Aviation 2]

Hi Max,

It is no problem, it should be quite easy.

Please can you tell me what the gauge reads at 60 Knots (what value in IOCards.test?).

Hi Max,

Okay, try this script:

Var 0002, name IAS_Servo, Link USB_SERVOS, Output 1, PosL 0, PosC 562, PosR 988, Type 2 // IAS Servo Instrument

Var 0001, name IAS, Link FSUIPC_IN, Offset $02BC, Length 4, // IAS from SIM
{
  L0 = DIV &IAS 128     // FSUIPC Conversion Airspeed IAS
  L0 = ABS L0     // L0 not signed 
  L2 = L0    
  IF L0 <= 60     // 1. Sector
      {
        L1 = L2 * 0.3333333     // ( 20 / 60) = 0.3333......
      }
      ELSE     // Out of range
    {
  IF L0 <= 100     // 2 sector
  {
    L1 = L2 * 2.675     // (107 steps/40 values) = 2.675
    L1 = L1 + 20     // Add steps of others sectors (+20)
  }
  ELSE     // Is a greater value
  {
    L2 = L0 - 100     //  L2 only have values for next sector
    IF L0 <= 200     // 3 sector
    {
      L1 = L2 * 3.69     // (369 steps / 100 values) = 3.69
      L1 = L1 + 127     // Add steps of others sectors (+20 + 107)
    }
    ELSE
    {
      L2 = L0 - 200     // L2 only have values for next sector
      IF L0 <= 300     // 4. Sector
      {
        L1 = L2 * 2.94     // ( 294 / 100) = 2.94
        L1 = L1 + 496     // Add steps of others sectors (20 + 107 + 369) 
      }
      ELSE     // Out of range
      {
        L2 = L0 - 300     //  L2 only have values for next sector
        IF L0 <= 400     // 5. sector
        {
          L1 = L2 * 1.980     // (198 steps / 100 values) = 1.980
          L1 = L1 + 790     // Add steps of others sectors (127 + 369 + 294)
        }
        ELSE
        {
          L1 = 988         // Max. position of IAS Gauge
        }
      }
    }
  }
  &IAS_Servo = 0 + L1     // Add to minimum (0)
}

Yeep. !

Now using that script with difference.

[Aircraft Aviation 2]

Hi Max,

Of course, you are right. I made a small mathematical error at the start of the script.

Try this one instead:

Var 0002, name IAS_Servo, Link USB_SERVOS, Output 1, PosL 0, PosC 562, PosR 988, Type 2 // IAS Servo Instrument

Var 0001, name IAS, Link FSUIPC_IN, Offset $02BC, Length 4, // IAS from SIM
{
  L0 = DIV &IAS 128     // FSUIPC Conversion Airspeed IAS
  L0 = ABS L0     // L0 not signed 
  L2 = L0    
  IF L0 <= 60     // 1. Sector
      {
        L1 = L2 * 0.333333     // ( 20 / 60) = 0.333333
      }
      ELSE     // Out of range
    {
    L2 = L0 - 60     //  L2 only have values for next sector
  IF L0 <= 100     // 2 sector
  {
    L1 = L2 * 2.675     // (107 steps/40 values) = 2.675
    L1 = L1 + 20     // Add steps of others sectors (+20)
  }
  ELSE     // Is a greater value
  {
    L2 = L0 - 100     //  L2 only have values for next sector
    IF L0 <= 200     // 3 sector
    {
      L1 = L2 * 3.69     // (369 steps / 100 values) = 3.69
      L1 = L1 + 127     // Add steps of others sectors (+20 + 107)
    }
    ELSE
    {
      L2 = L0 - 200     // L2 only have values for next sector
      IF L0 <= 300     // 4. Sector
      {
        L1 = L2 * 2.94     // ( 294 / 100) = 2.94
        L1 = L1 + 496     // Add steps of others sectors (20 + 107 + 369) 
      }
      ELSE     // Out of range
      {
        L2 = L0 - 300     //  L2 only have values for next sector
        IF L0 <= 400     // 5. sector
        {
          L1 = L2 * 1.980     // (198 steps / 100 values) = 1.980
          L1 = L1 + 790     // Add steps of others sectors (127 + 369 + 294)
        }
        ELSE
        {
          L1 = 988         // Max. position of IAS Gauge
        }
      }
    }
  }
  &IAS_Servo = 0 + L1     // Add to minimum (0)
}
}[/CODE]

So thats it.

Hi Max,

Please try this script for your VSI:

Var 0001, name VSI, Link USB_SERVOS, Output 2, PosL 127, PosC 448, PosR 1023, Type 2     // VSI Servo

  L0 = &VSI_D * 0.7895     // FSUIPC conversion, L0=VS
  L0 = ABS L0     // L0 not signed 
  L2 = L0    
  IF L0 <= 500    // First sector
  {
    L1 = L2 * 0.192     // (96 steps/500 values) = 0.192
  }
  ELSE     // Is a greater value
  {
    L2 = L0 - 500     //  L2 only have values for next sector
    IF L0 <= 1000     // Second sector
    {
      L1 = L2 * 0.184     // (92 steps / 500 values) = 0.184
      L1 = L1 + 96    // Add steps of others sectors
    }
    ELSE
    {
      L2 = L0 - 1000     // L2 only have values for next sector
      IF L0 <= 2000     // 3. Sector
      {
        L1 = L2 * 0.131     // ( 131 / 1000) = 0.131
        L1 = L1 + 188     // Add steps of others sectors 96 + 92
      }
      ELSE
      {
        L2 = L0 - 2000     // L2 only next sector
        IF L0 <= 4000     // 4. Sector
        {
          L1 = L2 * 0.0315     // ( 132 / 2000) =0.066
          L1 = L1 + 319    // Add steps of others sectors 92 + 96 + 131
        }
        ELSE     // Out of range
        {
          L1 = 1023         // Max. position

      }
    }
  }
  IF &VSI_D < 0     // If VSI is Negative
  {
    &VSI = 572 - L1     // Subctract from center
  }
  ELSE
  {
    &VSI = 572 + L1     // Else add to center
  }
}[/CODE]

Ok.
