PMDG 737 and OpenCockpits MCP

OK,

so just got my MCP panel from opencockpits and have started my SIOC for it, I was wondering if anyone was having issues with the speed of the rotaries due to keypresses having to be sent... So i started to have a play and came up with this.

Its so much better now, you can get quite nice fast changes with a fast spin, but keep the accuracy when slow.. enjoy :)

BTW it needs cleaning up so sorry about the naming etc :)

Code:

---

var 9991, name temphdg, value 0
var 9992, name LastHDGRot, value 0
var 8100, name Plus, Link SUBRUTINE
{
&temphdg = &plus

if &temphdg = &LastHDGRot
{
 &temphdg = 0
}
if &plus > 0
{
CALL &HDGplus
}
}

var 8101, name Minus, Link SUBRUTINE
{
&temphdg = &Minus

if &temphdg = &LastHDGRot
{
 &temphdg = 0
}
if &minus > 0
{
CALL &HDGminus
}
}


Var 8001, name HDGplus, Link SUBRUTINE
{
&KEYS = 47
&KEYS = 0
}
Var 8002, name HDGminus, Link SUBRUTINE
{
&KEYS = 48
&KEYS = 0
}



Var 9082, name HDGrot, Link IOCARD_ENCODER, Input 6, Aceleration 8, Type 2
{
&CRSRdisplay = &HDGrot
if &HDGrot > 0
{
IF &temphdg = 0
{
        &LastHDGRot = &HDGrot               
        &Plus = 0
        &Plus = TIMER &HDGrot 1 1
}
}
else
{

IF &temphdg = 0
{
    L1 = &HDGrot * -1
  &LastHDGRot = L1               
  &Minus = 0
  &Minus = TIMER L1 1 1
}       
}


  IF &HDGled = 0
  {
    L0 = &HDGrot * -1
    &MEMHDG = ROTATE 0 ,359 ,L0
  }
  CALL &HDGaff

}

Mr Roper

Many thanks for your recent contributions, your programming experience is proving very helpfull. It just shows what a forum can achieve with diverse skills.

Regards

David

Its curiuos..i no have any problem with sioc code from oc in my pmdg...but have little low speed in changes whe use OGS...thanks any way...:p

Thanks Mr Roper for this extract of your code.

I'll try to integrate it in my script in an attempt to solve the sluggish change of HDG values.

Cheers,
Sylvain

updated to include course, heading and altitude rotaries :)

I have also used a few different offsets, so that we dont have to remember the hdg etc when in LNAV/VNAV mode

This is simply fantastic!
After having seen some offsets in the various posts here I had been thinking about how I could use them optimally but you are too quick mate :lol:

Super!
I'll have to check this in the coming days (weeks maybe as real life is getting in the way quite a lot right now)!

MrRoper... We'll need you when PMDG releases the NGX... stick around please :wink:

Thanks again,
Sylle

Sorry if this is an elementary question, but I would be grateful if anyone could explain the mechanism by which IOCP communicates the change in state of the MCP push buttons in the script that Mr Roper has kindly posted.

For example:
I can see that Var 0060 the FD Switch depends on the state of I/O Card input 16, and the action is the &Keys=56/&Keys=0 toggle.

I can also see that the key press required by PMDG is either Ctrl+f or tab+f, so I'm assuming these must be mapped somewhere ? - But I can't see where at the moment.

I was looking at building my own microcontroller based MCP control hardware with a Visual Basic host app, but I was just weighing up whether to go that way or down the Opencockpits route.

Has anybody here tried building their own ?

Rob

the mapping is in the SIOC.cfg file at the bottem, the meanings for these are in the SIOC manual somewhere ;)

Ah - The missing link !

Thanks Mr Roper - Do you have any idea how one would get a VB app to send the keypress/scancode to PMDG ?

I guess, one would need to place the data into the keyboard buffer, but I can't see any reference to a method in the VB docs.

Cheers,

Rob

You are probably best using an API to send the key, you might even have to hook into the DirectX input but i doubt it.

Have a look ehre at the SendInput API

http://www.pinvoke.net/default.aspx/user32.SendInput

Thanks Mr Roper - I'll take a look at that link.

I have just found the statement sendkeys string this morning though.

I have tried it with the FD switch, and it works ok.
