Help needed with TRIM-wheel motor control

[Kremi54]

Hello Pete,

 

I need some help with the following issue.

 

In the FSUIPC Programmers Reference manual I found the following description about the elevator trim motor.

<<  Offset $3370 length 4  >>

Four single byte PFC driver ?alive counters:

3370 = COM port read thread alive and running
3371 = Elevator trim motor action (0=off, 1=up, 2=dn)                      <<== I need this value to start and stop my trimmotor
3372 = COM port write thread alive
3373 = Main FS chain alive

 

so i wrote a small sioc script as follows:
==========================================================================================
Var 20 name Motor_1 Link USB_DCMOTOR  Output 1   // DC motor variable control
Var 21 name TRIMWHEEl Link FSUIPC_IN Offset $3371 Length 4  // get TRIMWHEEL value from $3371 = Elevator trim motor action (0=off, 1=up, 2=dn)
{
  &Motor_1 = &TRIMWHEEL      // the motor change stops ans starts depending on &TRIMWHEEL
}
===========================================================================================
saved this file in the SIOC-config and started FSX, SIOC and Prosim completely,
but in flight I did not get any input in &TRIMWHEEL, checked in IOCPConsole from SIOC. I know I have to mask out bits, but the

contents of the &TRIMWHEEL is not filled, it stays zero.

 

Can you expalin to me what I do wrong ??

 

Do I need to load some extra .dll's ? I'm running SIOC version 4.01, have a full FSUIPC license and for the flight sim I run Prosim737, (licensed)

Okay. And presumably you are using a PFC 737 cockpit fitted with the motorised trim? And you are using the current version of the PFCFSX.DLL driver?

 

so i wrote a small sioc script as follows:==========================================================================================

 

Sorry, how does SIOC relate to PFC hardware? I'm lost!

Hello Pete,

Thanks for your help.. First let me describe the hardware i will be using for the trimotor.

I use FSX + Prosim737 and a Opencockpits DC- motor card controlled via Sioc. It is just a basic test to eventualy building a motorized trimwheel.

I found in the FSUIPC Reference manual an offset that I think that it is just what I need to control the DC-motorcard, namely:

the offset $3370, so I would like to use the value of byte $337, 0, 1 or 2 , in a Sioc script to use those values to control my motor.

The main question is , can I use the following declaration to get the value of offset $3370 in Var21 so I can convert Var21 into values I need to control my DC-motor card?

If I use the following script:

Var 21 name Trimwheel link Fsuipc_in offset $3370 length 4

Will the Var21 be filled wth contents from $3370 ?

If so, than I can use it, but when I tested it, nothing is filled in Var21.

Koos

But those offsets, 3370-3373 are just diagnostic values provided by my PFCFSX.DLL driver, which is only useful with the appropriate PFC manufactured hardware -- the 737 cockpit, in fact, the only serial port device they made with a motorised trim.

 

As for your SIOC declarations and so forth, I'm afraid they are lost on me. I do not use and never have used SIOC and i don't know anything about it.

 

Sorry,
