i'm using &msc SCROLL_UP/DOWN and &kp UP/DOWN on rotary encoders with the QDEC driver. if i move in one direction, after the final detent, sometimes a movement in the reverse direction occurs. is there any way to prevent this from happening in the firmware?

Is there a resolution sort of setting in the qdec driver? Symptom sounds like resolution is too low

after doing a bit of searching, i haven't found any https://docs.zephyrproject.org/latest/samples/sensor/qdec/README.html.
i have steps set to the number of detents, 24. when i rotate one detent, it registers 1 UP or DOWN. but when rotating multiple detents it'll often behave in the way described in the OP

steps is typically not the number of detents. It is usually 2x or 4x the number of detents, depending on the internal resolution of the encoder

i'll try 2x and 4x the detents. the resolution on the part datasheet is 24ppr

setting steps to 96 appears to have done the trick. thanks again 🙇♂️
if anyone stumbles across this issue in the future, the encoder i'm using is PEC12R-4220F-S0024
