[Bug] MOUSEKEY_BASE_SPEED has no effect in Kinetic mode

[y-usuzumi]

Describe the Bug

In Kinetic mode, as per the document, MOUSEKEY_BASE_SPEED controls the maximum mouse speed. However, no matter which value I give it, the maximum mouse speed seems to be the same. However, if I increase MOUSEKEY_MOVE_DELTA, the maximum mouse speed increases.

My config:

#define MK_KINETIC_SPEED
#define MOUSEKEY_INTERVAL 8
#define MOUSEKEY_MOVE_DELTA 4
#define MOUSEKEY_INITIAL_SPEED 1
#define MOUSEKEY_BASE_SPEED 100

My goal is to increase the duration from pressing a mouse cursor button to reach its maximum speed.

Thanks!

@drashna Do you have any idea what’s going on here? I think I am affected by the same bug on my Planck EZ. I set my base speed to 0 for testing purposes, and my maximum speed is still extremely fast.

Maybe it would be wise to take @liyang’s reimplementation instead of trying to fix the current code. The code looks cleaner and the documentation is so much more descriptive.

Edit: I think this issue might actually be a duplicate of #12082.

@y-usuzumi If all you want to archive is to increase the duration for reaching maximum speed, maybe setting MOUSEKEY_MOVE_DELTA to a lower value could help you. I don’t see why you would need to change MOUSEKEY_BASE_SPEED to archive this.

As a workaround for limiting the maximal speed, one can simply decrease the value of MOUSEKEY_MOVE_MAX instead of MOUSEKEY_BASE_SPEED. For example, add the following to your config.h:

#define MOUSEKEY_MOVE_MAX 20

I think the kinetic mode is still not working on v0.14.30. In mousekey.c, the ifndef MK_COMBINED clause takes precedence over ifdef MK_KINETIC_SPEED. However, MOUSEKEY_MOVE_DELTA is still used by the other mode, which is why.
