Hello ,
Does anyone know the correct Offset values for PMDG Flaps which work from a Servo,
I have tried alot of interpolation input and output settings but can't seem to get it right.
Thanks if anyone has them or can give me a few tips.
Regards
Nick

Hi Nick,

be so kind to give us more information. In which way did you try it? Is it possible for you to upload the pictures of your config (servo and offsets) or can you describe it in another way?
I think so we are able to help you.

Hi
The correct Flaps Offset is..... (For PMDG B737NGX)
Offset: 6568 Size: 8 Byte Type: FLT32 x 2 Name: MAIN_TEFlapsNeedle[2]

The First 4 Bytes are the FLT32 Offset for Flaps Left..... The second 4 Bytes are for Flaps Right.
( In the Real B73 and PMDG the Gauge include TWO needles... One for Left and one wor Rigth Flaps.... BUT you normaly not see it cause both needles work simultary..... Only if you habe a issue in one system like hydraulics the needles show different Data. )

So if you only like to simulate ONE Needle in your gauge use Offset 6568 ... 4 Bytes FLT32

Value have a LINEAR range from 0-40.... Now you only need to define in interpolation the steps like you use in your real gauge..... Use this tutorial to understand the basic technics.

Hi,
Thanks for the Info guys, I knew the correct Flap offset, but not the 4 Bytes for ONE needle.
I will try the Interpolation settings again and see how I go with that. I am using a Servo not a stepper Motor and I am wondering
if I use One pin only with all 9 Interpolation settings, because I did read somewhere you use separate output pins for each 9 settings.
I will keep you informed with what I find out.
Thanks
Nick

Negative !

In case of Servo or Stepper Motors you not need multiple Pins..... the Motor is controlled by the software.... So whatever you use Interpolation or not.... Whaever you have 1 or 100 Interpolation entrys..... The Motor work always same way with 1 Pin (Servo) or 4 Pin (Stepper) .

Maby you mixup a LED Tutorial. If you like to show the Flaps Position by using 9 different LED..... There you need a pin for every LED.....
Or you read a INPUT Guide.... If you not use a potentiometer and make a construction with 9 Switches.... then you need 9 Pins, too.

So keep Cool.... That workes.... (PS. Not forget the Transform to eleminate the Decimal problem that is explaned in the linked guide)

Hi ,

Thanks for correcting me, yes I have done that with LEDs, ok just One pin for Interpolation settings.
