Original layout is commented as keyboard-us-en (US-English). German layout is commented as keyboard-de (de = deutsch = "german"). Now there are two tables for keys with and without SHIFT-Key. It should be easier to implement different international layouts. However, it's bigger now and uses more memory. 2009-09-05 (Y-M-D) Fixed bugs - code bug on home-key fixed new replace-codes for de_ae, de_ou and de_ue New - Documentation of control-key bits This should be helpful for translatíons of this driver into different languages. - table_alt_r This table contains characters for the german "AltGr" key. - AltGr+F1..F12 Returns line-characters, selected from $90..$9f 2009-09-06 (Y-M-D) Fixed bugs - patch table_shift for "?" Differences to Parallax driver: - Different codes for NumLock, CapsLock and ScrLock to avoid conflict with german "ß" Codes are defined as constants and easy to change - Easy Cursor codes implemented to avoit conflict with the "Ä"-key Easy Cursor codes are easy to understand, for example "Cursor Left" is the character "←" ------------------------------------------------------------------} CON de_ae = $A6 'replace code - not used on keyboard de_oe = $A7 'replace code - not used on keyboard de_ue = $A8 'replace code - not used on keyboard lock = $BC 'Parallax used codes $DD, $DE and $DF 'There was a conflict between $DF=NumLock="ß" ScrLk = lock CpsLk = lock+1 NumLk = lock+2 ' 'Uncomment one of the next constant blocks ' ' {{Parallax cursor codes start}} {{ CrsLt = $C0E4 CrsRt = $C1E6 CrsUp = $C2E8 CrsDn = $C3E2 CrsHm = $C4E7 'Conflict with key "Ä" ($C4) CrsEn = $C5E1 PgUp = $C6E9 PgDn = $C7E3 Bksp = $00C8 Del = $C9EA Ins = $CAE0 Esc = $00CB Apps = $CC00 Power = $CD00 Sleep = $CE00 WkUp = $CF00 }} {{Parallax cursor codes end}} {{Easy cursor codes start}} CrsLt = $02E4 '← CrsRt = $03E6 '→ CrsUp = $04E8 '↑ CrsDn = $05E2 '↓ CrsHm = $06E7 '◀ CrsEn = $07E1 '▶ PgUp = $A0E9 ' PgDn = $A2E3 ' Bksp = $00C8 'È Del = $BAEA ' Ins = $BBE0 ' Esc = $001B ' Apps = $CC00 'Ì Power = $CD00 'Í Sleep = $CE00 'Î WkUp = $CF00 'Ï {{Easy cursor codes end}} VAR long cog long par_tail 'key buffer tail read/write (19 contiguous longs) long par_head 'key buffer head read-only long par_present 'keyboard present read-only long par_states[8] 'key states (256 bits) read-only long par_keys[8] 'key buffer (16 words) read-only (also used to pass initial parameters) PUB keystart(dpin, cpin) : okay '' Start keyboard driver - starts a cog '' returns false if no cog available '' '' dpin = data signal on PS/2 jack '' cpin = clock signal on PS/2 jack '' '' use 100-ohm resistors between pins and jack '' use 10K-ohm resistors to pull jack-side signals to VDD '' connect jack-power to 5V, jack-gnd to VSS '' '' all lock-keys will be enabled, NumLock will be initially 'on', '' and auto-repeat will be set to 15cps with a delay of .5s okay := startx(dpin, cpin, %0_000_000, %01_01000) PUB startx(dpin, cpin, locks, auto) : okay '' Like start, but allows you to specify lock settings and auto-repeat '' '' locks = lock setup '' bit 6 disallows shift-alphas (case set soley by CapsLock) '' bits 5..3 disallow toggle of NumLock/CapsLock/ScrollLock state '' bits 2..0 specify initial state of NumLock/CapsLock/ScrollLock '' (eg. %0_001_100 = disallow ScrollLock, NumLock initially 'on') '' '' auto = auto-repeat setup '' bits 6..5 specify delay (0=.25s, 1=.5s, 2=.75s, 3=1s) '' bits 4..0 specify repeat rate (0=30cps..31=2cps) '' (eg %01_00000 = .5s delay, 30cps repeat) longmove(@par_keys, @dpin, 4) okay := cog := cognew(@entry, @par_tail) + 1 PUB present : truefalse '' Check if keyboard present - valid ~2s after start '' returns t|f truefalse := -par_present PUB key : keycode '' Get key (never waits) '' returns key (0 if buffer empty) if par_tail <> par_head keycode := par_keys.word[par_tail] par_tail := ++par_tail & $F PUB getkey : keycode '' Get next key (may wait for keypress) '' returns key repeat until (keycode := key) PUB newkey : keycode '' Clear buffer and get new key (always waits for keypress) '' returns key par_tail := par_head keycode := getkey PUB gotkey : truefalse '' Check if any key in buffer '' returns t|f truefalse := par_tail <> par_head PUB clearkeys '' Clear key buffer par_tail := par_head PUB keystate(k) : state '' Get the state of a particular key '' returns t|f state := -(par_states[k >> 5] >> k & 1) CON ' Graphics-Objekt ''*************************************** ''* Graphics Driver v1.0 * ''* Author: Chip Gracey * ''* Copyright (c) 2005 Parallax, Inc. * ''* See end of file for terms of use. * ''*************************************** '' '' Theory of Operation: '' '' A cog is launched which processes commands via the PUB routines.
