It has 80 keys plus an Fn key; some of the keys have + Japanese labelings. It has an LShift and an RShift key, but only a + single Ctrl and Alt key. + The Fn key is internal to the keyboard. It makes the keyboard send + different scancodes if it is pressed, and an Fn keypress alone cannot + be intercepted. + + * Datel + The Datel Keyboard is a British IBM PS/2 keyboard that ships with an + adapter. + + * Tototek Adapter (the Lik-Sang one) + The Tototek adapter converts the IBM PS/2 protocol to the GameCube + SI protocol and also converts the PS/2 scancodes into GameCube + scancodes. The keys that have Japanese labelings on the ASCII + keyboard get mapped to keys like PrintScreen and Pause. + There are some interesting details about the Tototek Adapter: + 1) As there are no GameCube scancodes for RStrg and RAlt, the + adapter sends LStrg and LAlt instead. + 2) There are GameCube scancodes both for LShift (0x54) and RShift + (0x55), but the adapter sends LShift no matter which Shift key + is pressed. + 3) The key right of LShift on non-US keyboards sends no scancode. + 4) The Pause/SysReq key only sends the keycode of 0x37 once, even if + it's pressed down continuously. + 5) The Numpad is completely broken. The GameCube has no scancodes + for the Numpad, so Tototek seems to have tried to map the PS/2 + Numpad scancodes to GameCube scancodes. + The NumLock key sends 0x6A, a scancode that is undefined for the + GameCube. 0-9 and Enter send the scancodes of their counterparts + on the alphanumeric part of the keyboard, regardless of the + status of NumLock, so he Numpad cannot be used as cursor keys. + Numpad-- sends the same as -_, which is okay, but Numpad-+ sends + the same as ;: - this makes sense for the the Japanese ASCII + labeling only. + Numpad-* sends 0x37, the same as Pause/SysReq, but this one + continues sending it. And Numpad-/ sends 0x36, just like + PrintScreen. + 5) All combinations of Pause/SysReq with other keys are possible, + except for these: LStrg or LStrg together with Pause/SysReq + doesn't send anything. This would have been SysReq. + 6) The adapter easily gets confused by two keys for which it + produces the same GameCube scancodes: If you hold down LStrg + and press RStrg, the LStrg scancode will disappear even though + LStrg is srill pressed down. The same is true for Ctrl and Alt. + It would have made sense to add a switch that disables the scancode + conversion completely. Or, as a simple hack in the converter's + firmware, to always send the PS/2 scancode + 0x80 as a second key + if the scancode that is sent is ambiguous. +*/ #include <linux/input.h> #include <linux/module.h> @@ -49,14 +104,122 @@ static unsigned char gckbd_keycode[256] = { - 0, 0, 0, 0, 0, 0,102,107,104,109, 0, 0, 0, 0, 0, 0, - 30, 48, 46, 32, 18, 33, 34, 35, 23, 36, 37, 38, 50, 49, 24, 25, - 16, 19, 31, 20, 22, 47, 17, 45, 21, 44, 2, 3, 4, 5, 6, 7, - 8, 9, 10, 11, 12, 0, 43, 40, 26, 13, 55, 27, 51, 52, 53, 0, - 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 87, 88, 1,110,111, 41, + /* 00 */ 0, + /* 01 */ 0, + /* 02 */ 0, + /* 03 */ 0, + /* 04 */ 0, + /* 05 */ 0, + /* 06 */ 102, /* TODO: Home */ + /* 07 */ 107, /* TODO: End */ + /* 08 */ 104, /* TODO: PgUp */ + /* 09 */ 109, /* TODO: PgDn */ + /* 0a */ 0x46, /* ScrollLock */ + /* 0b */ 0, + /* 0c */ 0, + /* 0d */ 0, + /* 0e */ 0, + /* 0f */ 0, + /* 10 */ 30, /* A */ + /* 11 */ 48, /* B */ + /* 12 */ 46, /* C */ + /* 13 */ 32, /* D */ + /* 14 */ 18, /* E */ + /* 15 */ 33, /* F */ + /* 16 */ 34, /* G */ + /* 17 */ 35, /* H */ + /* 18 */ 23, /* I */ + /* 19 */ 36, /* J */ + /* 1a */ 37, /* K */ + /* 1b */ 38, /* L */ + /* 1c */ 50, /* M */ + /* 1d */ 49, /* N */ + /* 1e */ 24, /* O */ + /* 1f */ 25, /* P */ + /* 20 */ 16, /* Q */ + /* 21 */ 19, /* R */ + /* 22 */ 31, /* S */ + /* 23 */ 20, /* T */ + /* 24 */ 22, /* U */ + /* 25 */ 47, /* V */ + /* 26 */ 17, /* W */ + /* 27 */ 45, /* X */ + /* 28 */ 21, /* Y */ + /* 29 */ 44, /* Z */ + /* 2a */ 0x02, /* 1 */ + /* 2b */ 0x03, /* 2 */ + /* 2c */ 0x04, /* 3 */ + /* 2d */ 0x05, /* 4 */ + /* 2e */ 0x06, /* 5 */ + /* 2f */ 0x07, /* 6 */ + /* 30 */ 0x08, /* 7 */ + /* 31 */ 0x09, /* 8 */ + /* 32 */ 0x0a, /* 9 */ + /* 33 */ 0x0b, /* 0 */ + /* 34 */ 0x0c, /* -_ (or Numpad--) */ + /* 35 */ 0x0d, /* =+ */ + /* 36 */ 43, /* TODO: is either PrintScreen or Numpad-/ */ + /* 37 */ 40, /* TODO: is either Pause/SysReq or Numpad-* */ + /* 38 */ 0x1a, /* [{ */ + /* 39 */ 0x27, /* ;: (or Numpad-+) */ + /* 3a */ 0x28, /* '" */ + /* 3b */ 0x1b, /* ]} */ + /* 3c */ 0x33, /* ,< */ + /* 3d */ 0x34, /* .> (or Numpad-,) */ + /* 3e */ 0x35, /* /?
