    Sioc Leading Zero Blanking Probs

    Hi Guys,

    Having a problem with blanking a leading zero on a O/C Display II card. I've tried to follow Nico Howto which was very helpful.

    I have a four digit display for RPM and when below 1000rpm I want the leading zero supressed. I have run my code thru the IOconsole

    in SIOC and it seems to give me the correct values UNTILL I hit > 1000 or 2000 rpm. It then goes weird giving incorrect values.

    When operated with the hardware, Master card outputs and other Displays operate even though they are not configured in Sioc.

    Could someone please review my code and see where im wrong and correct if possible. My maths and programming skills are

    very basic and all help would be appreciated.

    Here is the code and thanks

    Les



    Code:
    Var 6020, name rpm, Link FSUIPC_IN, Offset $0898, Length 2, Type 1
    {
      L0 = &rpm * 10800
      L1 = L0 / 65536
      L2 = MOD L1 10
      &Digitr = L2
      L2 = MOD L1 100
      &Digitl1 = L2
    
      L2 = MOD L1 1000
      &Digitl2 = L2
    
      L2 = Div L1 1000
      IF L2 < 1
     {
      &Digitl3 = -999999
     }
     ELSE
     {
      &Digitl3 = L2  
     }
    }
    
    
    Var 1, name Digitr Link IOCARD_DISPLAY, Digit 0, Numbers 1
    
    Var 2, name Digitl1 Link IOCARD_DISPLAY, Digit 1, Numbers 1
     Var 3, name digitl2 Link IOCARD_DISPLAY, Digit 2, Numbers 1
     Var 4, name Digitl3 Link IOCARD_DISPLAY, Digit 3, Numbers 1

    Re: Sioc Leading Zero Blanking Probs

    Hi Les,

    It looks to me that the second and third digits are also wrong.
    You forgot to divide by 10 before doing the Modulo operations. You have to divide by 10 in order to get the next digit.

    Try this:
    Code:
    Var 6020, name rpm, Link FSUIPC_IN, Offset $0898, Length 2, Type 1
    {
      L0 = &rpm * 10800
      L1 = L0 / 65536
    
    
      L2 = MOD L1 10
      &Digitr = L2
      L1 = DIV L1 10
      L2 = MOD L1 10
      &Digitl1 = L2
      L1 = DIV L1 10
      L2 = MOD L1 10
      &Digitl2 = L2
      L1 = DIV L1 10
      L2 = MOD L1 10
      IF L2 = 0
      {
        &Digitl3 = -999999
      }
      ELSE
      {
        &Digitl3 = L2  
      }
    }
    Regards,
    Nico

    Re: Sioc Leading Zero Blanking Probs

    Hi Nico,
    Thanks, it works fine now in sioc sim, i thought i could do div with the Mod, but obviously i was wrong. Didnt think
    to do div first.
    Regards
