Hello,
I'm using Prepar3D / generic aircraft.
I checked an analog input with release 9.0. I selected FSUIPC-EventID / AXIS_RUDDER-SET, 65764. It doesn't work.
Same with the other axis (Aileron, Elevator).
On the same card Arduino 2560, buttons are well functioning.

May I have some help please

I was also looking for an analog input method.
It is explained here.

OK

I still not test it.... My Poti is not deliverd from China till now.
But i still see some examples from other users.

The Poti gives a value of 0-1024. So if you use the "@" as explaned in the linked guide then Mobiflight will send this value to the Sim.

About Problems:

1. Get sure the used Offset allow you to WRITE it. For sure we can NOT write a Offset that is marked as "Read Only".

2. Think about usecase. I personally not recommend to use a MF Poti for Controlls like Rudder, Throttle, Aleron and so on. Here a Joystick Controller and the Windows/Sim internal HID Controllers are 1000 times more comfortable , accurate and more easy !
Poti via MF are used for things like Dimm Lights and some specila elements !

3. Recalculate the Value so it fit to the Range of the Offset in the Sim.
Remember.... The Poti gives a Value "0-1024" ...... The Rudder Axis in FSUIPC is for example -16383 to +16383
So we need a Formula to make this compatible.
if(@<512,(@-512)*32*-1,@*32)
NOTE: i not test this in case i got no poti..... May its wrong. Please try out !
Good Luck !
