SIOC Help Needed

I am trying to program my landing gear lever in sioc using the following but it doesn't seem to be working

Code:

---

Var 1, name gear_control, Link FSUIPC_OUT, Offset $0BE8, Length 4

Var 2, Link IOCARD_SW, Device 3, Input 20, Type P
        {
        &gear_control = 0
        }

Var 3, Link IOCARD_SW, Device 3, Input 21, Type P
        {
        &gear_control = 16383
        }

---

the script compiles without errors but doesn't operate the landing gear.

Can any sioc experts help?

Hi,

In your script each time the push button changes value (0->1 and 1-> 0) the "gear_control = .. " statement is executed.
However, that should only happen when the button is pushed.

Try this:

Code:

---

Var 1, name gear_control, Link FSUIPC_OUT, Offset $0BE8, Length 4

Var 2, Link IOCARD_SW, Device 3, Input 20, Type P
{
  IF v2 = 1
  {
    &gear_control = 0
  }
}

Var 3, Link IOCARD_SW, Device 3, Input 21, Type P
{
  IF v3 = 1
  {
    &gear_control = 16383
  }
}

Hi Nico,

Thanks for the reply, I have tried your suggestion but unfortunately it still isn't working. A bit of experimentation has shown that If I change the Var 1 statement to make it light an led instead of writing to the FSUIPC offset it works so the code is executing - there is obviously something going wrong in the process of writing to FSUIPC, just not sure what!

Further update: I have tried changing the code to write to a different offset (used the one to pause/un-pause the sim) and this worked so it seems that my code is working OK but the offset I am writing to is not working as expected. I am writing to offset 0BE8 which is listed as Gear control 0=Up, 16383=Down - I would have expected this to raise / lower the gear but it doesn't seem to be doing anything. (I am using the default 737-800 for testing).

Problem solved!! I have used offset 3110 (send controls) instead of 0BE8, using this to send the values 66080 (gear down) and 66079 (gear up) has everything working as expected!
