Devicelink Functionality

[Storebror]

Actually the DeviceLink output is just fine.
A turn/slip indicator can use any range of values for turn and slip.
IL2 uses the physical degree value for slip, which is reasonable.
Furthermore IL2 uses a standard rate 1 turn for the turn indicator at 50%, which is reasonable too.
This means that when the output for the turn indicator can have values from -1.0 to +1.0, then -1.0 means 6 degrees per second to the left, -0.5 is 3 degress per second to the left (rate 1 turn), 0 is straight, +0.5 is 3 degrees per second to the right and +1.0 is 6 degrees per second to the right.

You will have to adjust the min/max values for your indicator like
Minimum Value = -1
Maximum Value = 1
In case your turn indicator's maximum values are twice a standard turn as well, otherwise adjust the values so they match the maximim 6 degrees per second output from IL2.

As long as Data type = Float is set, everything should be fine.

Excellent reply Storebror, was hoping some one would throw the dog a bone!
I needed something to naw on! Now just need to figure out how to apply your information.

I sent an e-mail to FI tech support, but unfortunately their tech support is not as good as their product! Hopefully they will reply.

I have 9 gauges working, but the turn/slip one is a bit different. Here is what their software looks like for turn/slip......

FI- had min value -1000 & max 1000 , I changed to -1 & 1 , but no joy.

This is were the problem may be with understanding how to set values to needle movements!!!! Can use anywhere from 3 to 20 needle values.

Needle has position numbers , values per position?

Well, this is a bit hard to judge for someone who doesn't have the same piece of hardware.

Let's rule out the easiest thing first:
Is DeviceLink putting out values for turn/slip yes or no?
This can be answered first by taking a look into IL-2's code where it's plain to see that in online sessions this output will be suppressed.
You should fly offline for your tests though.
Next we can give it a try with a sample client app.
I've made one for Android to check what I get back from DeviceLink and this is what I see flying offline:

Slip Deg. and Turn Ind. show valid values which means "it works".

Now we see these lines in your G-Step functions maintenance window:

030, Slip, Position, Gauge,  , 04, 034, 000, 0, 1, 1
031, turn, Position, Gauge,  , 04, 036, 000, 0, 1, 1

Whether or not "turn" should have a capital "T" is debateable.
The DeviceLink query parameters (34, 36) seem fine.
Comparing this to other DeviceLink Parameters configured there, we see that these two lines have a "000" behind the DeviceLink Parameter, whereas others have "001" at that place.
Can it be that there's a mistake here?
Furthermore you once mentioned that the default config for turn gauge has value ranges of -1000 to +1000.
How about applying a multiplier of 1000 to that gauge?
In my book the line should look like this:

031, turn, Position, Gauge,  , 04, 036, 001, 0, 1000, 1

Pfeil, I appreciate your post have been watching it for some time waiting to see if D-team was going to input. Hope you don't mind me using it. Thought about starting another but figured you would not mind keeping it alive!

Storebror, Not sure how to look into IL-2 code, not familiar with sample client app? Is this a app I can download somewhere?

Looking @ G-step functions, devicelink configured parameters, looks like all the other position category functions do have the "000" behind the devicelink parameter. The engine functions have the "001" Also have a look at the multiplier numbers for the VSI and attitude.

I tried...

Code:

031, turn, Position, Gauge, , 04, 036, 000, 0, 1000, 1

No joy

No sorry, that's just something I've started locally for a planned project (remote gauges on Android Devices), but the project stalled.
The app is not publically available and spreading development apks isn't quite my style of software distribution

I think the bottom line is that DeviceLink does send the right float values for slip and turn when you fly offline (online it will just send 0's for these values).
If your software cannot pick up these values, you should get in contact with that software manufacturer.

Thanks for input/replies Mike, was helpfull. Flight Illusions tech support did send me an e-mail yesterday asking for my config file. Hopefully they will be able to help me.
