Remapping keyboard with VoodooPS2

Those keys are NX keys... from VoodooPS2Keyboard.cpp:
Code: 
        NX_KEYTYPE_PLAY,        0x34,
        NX_KEYTYPE_NEXT,        0x42,       // if this event repeated, act as NX_KEYTYPE_FAST
        NX_KEYTYPE_PREVIOUS,    0x4d,        // if this event repeated, act as NX_KEYTYPE_REWIND



It is work you need to do, not me. You can find out how to capture ACPI events in the brightness guide.

Thank you for the codes :)

I tested the keys and got an output for each combination:
Fn only:
default 20:50:24.892997 +0200 kernel ACPIDebug: "EC _QD3 enter"
default 20:50:24.893219 +0200 kernel ACPIDebug: "EC _QD3 exit"
default 20:50:25.018264 +0200 kernel ACPIDebug: "EC _QD4 enter"
default 20:50:25.018488 +0200 kernel ACPIDebug: "EC _QD4 exit"

Fn+Down Arrow (should be play/pause):
default 20:51:38.608152 +0200 kernel ACPIDebug: "EC _QD3 enter"
default 20:51:38.608385 +0200 kernel ACPIDebug: "EC _QD3 exit"
default 20:51:38.839506 +0200 kernel ACPIDebug: "EC _Q6F enter"
default 20:51:38.839738 +0200 kernel ACPIDebug: "EC _Q6F exit"
default 20:51:38.909295 +0200 kernel ACPIDebug: "EC _QD4 enter"
default 20:51:38.909474 +0200 kernel ACPIDebug: "EC _QD4 exit"

Fn+Right Arrow (should be next):
default 20:52:40.293189 +0200 kernel ACPIDebug: "EC _QD3 enter"
default 20:52:40.293427 +0200 kernel ACPIDebug: "EC _QD3 exit"
default 20:52:40.567926 +0200 kernel ACPIDebug: "EC _Q6D enter"
default 20:52:40.568063 +0200 kernel ACPIDebug: "EC _Q6D exit"
default 20:52:40.898467 +0200 kernel ACPIDebug: "EC _QD4 enter"
default 20:52:40.898713 +0200 kernel ACPIDebug: "EC _QD4 exit"

Fn+Left Arrow (should be previous):
default 20:53:28.092488 +0200 kernel ACPIDebug: "EC _QD3 enter"
default 20:53:28.092726 +0200 kernel ACPIDebug: "EC _QD3 exit"
default 20:53:28.356237 +0200 kernel ACPIDebug: "EC _Q6C enter"
default 20:53:28.356434 +0200 kernel ACPIDebug: "EC _Q6C exit"
default 20:53:28.612699 +0200 kernel ACPIDebug: "EC _QD4 enter"
default 20:53:28.612892 +0200 kernel ACPIDebug: "EC _QD4 exit"

If I understood correctly, should I use these patches?
Code: 
into method label _Q6F replace_content
begin
// Play Pause\n
    Notify(\_SB.PCI0.LPCB.PS2K, 0x0034) //PlayPauseKey\n
end;
into method label _Q6D replace_content
begin
// Next\n
    Notify(\_SB.PCI0.LPCB.PS2K, 0x0042) //NextKey\n
end;
into method label _Q6C replace_content
begin
// Previous\n
    Notify(\_SB.PCI0.LPCB.PS2K, 0x004d) //PreviousKey\n
end;

Additionally, I see that my Fn key sends a code alone. Can I make it work on macOS?
What about the ACPIDebug kext+Patches? should I keep them installed/applied?

Thank you!

Notify does not use ADB codes. It accepts "modified" PS2 codes.

And I don't know what Fn+arrows have to do with your media controls.

So how can I use ADB? If I can...
What should the modified PS2 codes be? :p

As you saw, my Fn key sends a 'signal' even if I only press it without another key. How can I make it work on macOS too? (Edited the last comment too late :p )

It is not possible to send ADB codes directly via Notify. Must send PS2 codes that are mapped to ADB.

See brightness guide: https://www.tonymacx86.com/threads/guide-patching-dsdt-ssdt-for-laptop-backlight-control.152659/

You would need to determine how to detect that in ACPI and send a PS2 code that can map to Fn ADB.

I found this inside VoodooPS2's keyboard info.plist:
Code: 
<string>46=4d;scroll =&gt; Previous-track</string>
                            <string>e045=34;pause =&gt; Play-Pause</string>
                            <string>e052=42;insert =&gt; Next-track</string>
What I can understand from here?
If it's nothing (guess it really can't help me), In which way I can find them?

Thanks!

Those are "Custom PS2" mappings for a specific laptop. They map the PS2 codes on the left of the '=' to the ADB codes on the right of the '='.

The same can be done via ACPI/RMCF.

But how it's done?
Sorry for asking too much questions, but I really don't understand. :(
Thanks again.

You will need to be much more specific about what you're trying to accomplish.

Getting the PS2 code for Play/Pause+Next+Previous.
The codes I should put inside my DSDT Patch.
