How use input Axis class with an digital input digital potentionmeter

[camzilla1050]

Hi,
I'm using JoystickXL on a Adafruit CircuitPython 10.0.3 on 2025-10-17; Raspberry Pi Pico with rp2040 to build a throttle device for x-Plane12 on linux.
The simple version worked fine with 3 Axes + 2 buttons and is recognized perfectly by X-Plane.

But now I replace the 3 faders potentiometers by 3 hall effect captors + a digital pot ( based on the arduino rudder pedals project ).

I've also add an hcf4051 Analog Multiplexer due to limitations in my Raspberry Pico i/o.

• Input: Hall effect captors -> hcf4051 Multiplexer -> board.A0
• Outpout : code.py -> digital pot MCP41050

The problem for me now is Axis input class accepts only Analog input. Some one has an idea how to solve it?

Tnx
