Hello gents,

I am new to AAO and am attempting my first binding. My first goal is to assign a physical axis (Saitek Throttle Quadrant lever) to the turbocharger lever found in the Aeroplane Heaven P-47D (which has no in-sim binding). Thus far, I have managed to bind the two, but strangely enough, when I move the physical axis on the Saitek, instead of a smooth response from "off" to "full", I get an on/off style of response in roughly the middle of the lever's throw instead, i.e., I move the physical lever a ways and the virtual lever snaps from one end of it’s travel to another. No in-between. This is not what I want. Can anyone more familiar with AAO give any helpful pointers?

(For clarity, the turbo lever on the P-47 is a proportional one, the more or less it is advanced, the more or less boost the engine receives).

Many thanks in advance-

Chris

How did you do this, what did you assign exactly to operate this lever? Event, axis variable, LVar, IE, BVar, - ??

Most likely, the axis range is wrong for the event/variable that you are using (= the Axis Min, Max and Rounding settings don't match what your target expects)

Also, not every lever has full axis coverage. For example the Asobo Condition Levers only have three settings = values (0,1,2). You cannot set the lever to a position between those.

Thank you very much for responding, 

I assigned the following: IE:INSTRUMENT_LEVER_boost_control. I entered it in the Enter Variable  field of the Change Axis Assignment window of AAO. I believe this is referred to as an Input Event (it is the onlything I can enter that makes the virtual lever move at all).

I can't post an image but the values ranges are as follows 

Filter =1

"Prog" is ticked

Axis Min =-16838

Axis Max = 16383

Shift = 0

Update Value = Continuously

Roundings = Int

No need to type them, once you are connected to the sim, AAO will read the IEs for this aircraft from MSFS. The IE's can then be selected from the normal events list ("Select simulator event"), on the tab "MSFS IEs"

Axis Min, Max and Rounding are probably wrong and must be changed. Check the value range either in MSFS developer mode or in AAo using "Scripting->Watch simulator events".
My guess would be Min = 0 (or -1) and Max = 1, Rounding = Float. Numerical value boxes are either changed with the mouse wheel (left half = big changes, right half = small changes) or by doubleclick + type.

Do not set the axis to "continuously" unless you have to. When you do this, the app will constantly send a signal to the sim, even when you are not moving the lever at all.

Clicking on the grey question mark in the top menu opens the PDF manual - lots and lots of information in there, 200 pages worth.

THAT WORKED!!!! 🤩

Thank you!!!

Chris

 

I found the gray question mark to access the pdf, but nothing happens when I click it?

UPDATE: nevermind and thank you, I found a pdf of the manual I can use, ver. 4.5.5.

Thank you again for your help-

Chris
