Hall sensor value in Freejoy different to that using Leo Bodnar BU0836A

[psjshep]

Hi,
I am not an electronics expert but an enthusiast.

• I am using the Authentikit project to 3D print flight sim controls (this example, a Spitfire throttle)
• That utilises a Leo Bodnar BU0836A 12-bit joystick interface
• the throttle uses 3 x A1324LUA-T Hall Effect Sensors for 3 axis (Mixture, throttle & prop RPM)
• I am trying to use a STM32F103C8 instead as it has more buttons available - this has properly flashed & I am able to configure & use buttons & axis.
• using Windows "Setup USB game controllers" utility, & ticking "display raw data" I can see the values received.

Q1
Why are the values shown in the windows utility different to that shown in the FreeJoy configurator?

Q2
The max value tops out at 32767 on the throttle axis before reaching full travel, but does not when using the BU0836A - is there some reason for this?

Thx, & be gentle with me :)
Phil

Additional:
For FreeJoy, the minimum value is around -2500 & maxes out at 32767 about 4/5 of the movement

For BU0836A, min val is 1250 & max is 3750!
