30 | Author: Giuseppe Lipari |
||
31 | Start date: 19/6/96 |
||
32 | |||
33 | File: Keyb.C |
||
34 | Revision: 1.5.1 |
||
35 | |||
36 | Last update : 14/Apr/1999 |
||
37 | |||
38 | This file contains : |
||
39 | -- A fast handler that get the scan code from the key interface |
||
40 | and put it in a port (non blocking) ; Inside this handler we can't |
||
41 | make any primitive call; it runs with interrupt enabled, so that the |
||
42 | timer cannot be blocked. Its priority is 1 (from hardware). |
||
43 | -- A sporadic soft process that gets the data from the port and |
||
44 | tries to recognize any scan code. With the help of a table that varies |
||
45 | from keyboad to keyboard (e.g. italian vs american) it puts the ascii |
||
46 | code intoanother port, with a byte that indicates the pression of any |
||
47 | control key (Shift, Ctrl, Alt). I tried to make the initialization |
||
48 | of this table as standard as possible, so that one has to change only |
||
49 | the include file with all the codes |
||
50 | -- Some functions (exported) to initialize the interface and get the |
||
51 | ascii code |
||
52 | |||
53 | Revision 1.4 (Gerardo) Added support for italian keyboard; required |
||
54 | to add a new status variable rightalt to cope with italian keybs |
||
55 | assignment! Added the keyb_set_map function to select the keymaps |
||
56 | and finally build the english & italian keymaps |
||
57 | |||
58 | Revision 1.5 (Giorgi) |
||
59 | |||
60 | Split the file into keyb.c and 8042.c: |
||
61 | 8042.c low level hardware interface |
||
62 | keyb.c user interface to kerboard routines |
||
63 | (8042.c is the "source" of data that keyb.c must interpretate) |
||
64 | |||
65 | Modification made: |
||
66 | -- fast handler remove (now in 8042.c) |
||
67 | -- all function that make direct I/O with hardware now in 8042.c |
||
68 | -- keyb_init() modified (to interfaces with 8042.c) |
||
69 | -- key_sendKeyCmd() removed; key_sendCtrCmd() removed |
||
70 | -- scanCode() & KeyProc modified (keyboard ACK are tested in KeyProc) |
||
71 | -- actled() removed (now in 8042.c with name 8042_keyboardleds); all |
||
72 | reference changed |
||
73 | -- Key_1 port removed (comunication in handled by functions in 8042.c) |
||
74 | -- added functions to enable/disable keyboard |
||
75 | |||
76 | PS: the modification are marked with "MG" |
||
77 | |||
78 | Revision 1.5.1 (Giorgi) |
||
79 | |||
80 | Modification to compile on 3.2.0 |
||
81 | -- added wcet time to all task |
||
82 | -- RECEIVE port now are STREAM port |
