Encoder scroll not working after switching branch

[eerraa]

I've been using my keyboard with the following keymap code compiled on the petejohanson/zmk/tree/feat/pointers-move-scroll branch:

#include <behaviors.dtsi>
#include <dt-bindings/zmk/bt.h>
#include <dt-bindings/zmk/keys.h>
#include <dt-bindings/zmk/mouse.h>
#include <dt-bindings/zmk/outputs.h>
#include <dt-bindings/zmk/rgb.h>

#define ZMK_MOUSE_DEFAULT_MOVE_VAL 1200  // 600
#define ZMK_MOUSE_DEFAULT_SCRL_VAL 100   // 10

/ {
    behaviors {
        mmv {
            acceleration-exponent = <1>;      // 1
            time-to-max-speed-ms = <1000>;    // 500
            delay-ms = <0>;                   // 0
        };

        msc {
            acceleration-exponent = <1>;      // 0
            time-to-max-speed-ms = <400>;     // 300
            delay-ms = <0>;                   // 10
        };

Recently, I switched to the petejohanson/zmk/tree/feat/pointers-with-input-processors branch to use ZMK STUDIO. However, after switching, the encoder's scroll up and scroll down functions stopped working.

I've spent some time trying to figure out what changes might have caused this issue, but I haven't been able to identify the reason. Could someone help me understand why this is happening and how to fix it?

My ZMK config repository is available at: https://github.com/eerraa/zmk-config-sofle

Thank you in advance for your help!

(Note: I apologize if my question seems basic - I'm new to programming and English isn't my first language.)

To override the speed, you need to #define ZMK_MOUSE_DEFAULT_SCRL_VAL etc. before #include <dt-bindings/zmk/mouse.h>, since they affect how SCRL_DOWN etc. are defined in the header.

Maybe in the previous branch the speed adjustment wasn't needed, but in this one the scale of scroll values are different so it is needed, not sure.

I also don't think your mmv or msc overrides do anything, because the node names are different: https://github.com/zmkfirmware/zmk/pull/2477/files#diff-1a97e7069fcda9561fe5cdda2b476644bbba071fa6d4c286777a50f90a3269fcR12. You'd be better off using the usual &msc {...}; approach to override values.

As an aside, please keep questions for features not in main branch either in ZMK Discord (#pointing-devices channel is good for this), or at least in the PR itself (#2477).
