joystick adc noise / random shaking in center #37

observations

even though joystick is calibrated recently, the armchair moves slightly / shakes randomly when not touching joystick

fading makes it less significant
its very noticable in sport-mode (8x button press)
stronger shaking for some time after startup
- temperature?
- previous mechanical stress from cover just removed
general issue with noise e.g. when driving slowly it feels shaky

ideas

[x] analyse signal with scope
[x] debug signal with logging
hardware filter? (R-C)
software filter?
