Add support for IBM M-50 to ibmpc_usb

[RaoulDuke-Esq]

Hi Hasu,

Would it be possible to add layout support for the M-50 (50 key IBM keypad) to ibmpc_usb? When loaded with the baseline ibmpc_usb firmware it registers as ID:AB83(AT) and sends the following:

All letters send as lowercase but are shown shifted for ease of read
A W E R \ U I O ; . (keypad dot)
Z X C V ENTER M , L . ?
1 2 3 4 F10 7 8 9 0 " (numbers are NOT keypad numbers)
LSFT F1 F2 5 F9 6 = F8 [ -
LCTL LALT F3 T BSPC Y. ] F6 F7 H

Can you share hid_listen ouput when the keyboard is plugged in?

Keboard layout is defined just as CPP macro like this.

tmk_keyboard/tmk_core/common/unimap.h

Line 49 in 792074f

#define UNIMAP( \

You can define your layout in your keymap(unimap) file, unimap_plain.c for example.

'A' is identified by code 0x04 in unimap and 'W' by 0x1A.

tmk_keyboard/tmk_core/common/unimap.h

Line 103 in 792074f

UNIMAP_A, // 0x04

So K04 and K1A are placed for A and W in paramter list part. you have to do that for all other keys.
Unused codes should be defined as AC_NO in the latter part.

#define UNIMAP_M50( \
    K04, K1A, ... K66, \
...
    K78, K7A, ... K0B \
) { \
    { AC_NO,    AC_NO,    AC_NO,    AC_##K03, AC_##K04, AC_##K05, AC_##K06, AC_##K07,   /* 00-07 */ \

Thanks Hasu. I'll try creating a unman using those instructions.

I don't seem to be able to run hid_listen on any of my computers but I am able to get the console output:
