[Bug] Mouse key MS_BTN1 ~ MS_BTN8 are not working when PS/2 trackpoint enabled with RP2040 MCU #24599

Describe the Bug

Hi, I'm trying to create a keyboard with trackpoint module for myself.
I've got the PS/2 trackpoint module and use Raspberry PI PICO (RP2040 MCU) to test my QMK firmware.
I've enabled the PS/2 mouse and vendor driver in keyboard.json and the trackpoint works fine. Then I tried to update my keymap to support sending mouse button click(left/middle/right button click) from my keyboard, but I find it is not working. The tricky thing is only MS_BTN1 ~ MS_BTN8 are not working, others works fine(e.g. the wheel scroll keycode MS_WHLU and MS_WHLD).
I tried to disable the PS/2 module and driver then the result is MS_BTN1 ~ MS_BTN3 are working again. I can send mouse click from my keyboard.
is this a conflict between RP2040 ps2 vendor driver and mouse key feature? How can I resolve this and let my trackpoint and mouse keycode work together? Or maybe @gamelaster can give some suggestions from ps2_vendor.c side?

I used the latest master branch qmk_firmware repository.
Below are my related files (my keyboard name is nomouse):

Hi, from PS/2 mouse, there is bitfield which just contains left, middle and right button state. It is passed then to QMK PS/2 interface. I am just using the keyboard with PS/2 trackpoint and mouse buttons works just fine.

I have no idea what mouse_key property does at all, so I can't help with this. Although, I don't think the issue is in RP2040 PS/2 PIO driver.

do you know how can I debug this? I dont know how to resolve it now... 😂 @gamelaster

gamelaster · 2024-11-16T08:45:00Z

@tachikomachann I am sorry, no clues :(

tachikomachann · 2024-11-17T04:01:41Z

@gamelaster I do more test and try to dig more details:

Add debug log in process_record_user and find the MS_BTN1 ~ MS_BTN3 keycode can be processed in this, so I think the pin connection and key press event should be correct?

I keep the the ps/2 mouse config and just remove ps/2 trackpoint module from my breadboard. Mouse key can send left/middle/right click after removing the module.
I find the MS_BTN3 become the scroll button(i.e. hold the MS_BTN3, trackpoint movement will become mouse wheel scroll ) even though I don't enable any scroll button setting.

According above details, maybe I can confirm that the mouse key buttons behavior is overridden by ps/2 module? Can I override the behavior of MS_BTN1 ~ MS_BTN3 in process_record_user as a workaround? I'm not familiar with ps/2 driver code and don't know how to troubleshoot in ps/2 code
