Add support for IBM M-50 to ibmpc_usb

RaoulDuke-Esq commented 2 years ago

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. https://github.com/tmk/tmk_keyboard/blob/792074f49b30ea9d39becdd3364cac7883024ac9/tmk_core/common/unimap.h#L49

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. https://github.com/tmk/tmk_keyboard/blob/792074f49b30ea9d39becdd3364cac7883024ac9/tmk_core/common/unimap.h#L103

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 */ \
      AC_##K08, AC_##K09, AC_##K0A, AC_##K0B, AC_##K0C, AC_##K0D, AC_##K0E, AC_##K0F }, /* 08-0F */ \

      AC_##K18, AC_##K19, AC_##K1A, AC_##K1B, AC_##K1C, AC_##K1D, AC_##K1E, AC_##K1F }, /* 18-1F */ \

    { AC_##K30, AC_##K31, AC_##K32, AC_##K33, AC_##K34, AC_##K35, AC_##K36, AC_##K37,   /* 30-37 */ \
      AC_##K38, AC_##K39, AC_##K3A, AC_##K3B, AC_##K3C, AC_##K3D, AC_##K3E, AC_##K3F }, /* 38-3F */ \
    { AC_##K40, AC_##K41, AC_##K42, AC_##K43, AC_##K44, AC_##K45, AC_##K46, AC_##K47,   /* 40-47 */ \

    { AC_##K50, AC_##K51, AC_##K52, AC_##K53, AC_##K54, AC_##K55, AC_##K56, AC_##K57,   /* 50-57 */ \

    { AC_##K60, AC_##K61, AC_##K62, AC_##K63, AC_##K64, AC_##K65, AC_##K66, AC_##K67,   /* 60-67 */ \

}

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:

tmk / tmk_keyboard
