|

Commands
|
||||
--------
|
||||
ADB command is 1byte and consists of 4bit-address, 2bit-command
|
||||
type and 2bit-register. The commands are always sent by Host.
|
||||
|
||||
Command format:
|
||||
7 6 5 4 3 2 1 0
|
||||
| | | |------------ address

A A A A 1 0 R R Listen(write to a device)
|
||||
A A A A 1 1 R R Talk(read from a device)
|
||||
|
||||
The command to read keycodes from keyboard is 0x2C which
|
||||
consist of keyboard address 2 and Talk against register 0.
|
||||
|
||||
Address:
|
||||
2: keyboard
|
||||
3: mice
|
||||
|
||||
Registers:
|
||||
0: application(keyboard uses this to store its data.)
|

1: application
|
||||
2: application(keyboard uses this for LEDs and state of modifiers)
|
||||
3: status and command
|

Communication
|
||||
-------------
|
||||
This is a minimum information for keyboard communication.

[from Apple IIgs Hardware Reference Second Edition]
|
||||
|
||||
Criterion for bit0/1:
|
||||
After 55us if line is low/high then bit is 0/1.
|
||||
|
||||
Attention & start bit:
|
||||
Host asserts low in 560-1040us then places start bit(1).
|
||||
|
||||
Tlt(Stop to Start):
|
||||
Bus stays high in 140-260us then device places start bit(1).
|
||||
|
||||
Global reset:
|
||||
Host asserts low in 2.8-5.2ms. All devices are forced to reset.
|
||||
|
||||
Service request from device(Srq):
|
||||
Device can request to send at commad(Global only?) stop bit.
|
||||
Requesting device keeps low for 140-260us at stop bit of command.
|
||||
|
||||
|
||||
Keyboard Data(Register0)
|
||||
This 16bit data can contains two keycodes and two released flags.

First keycode is palced in upper byte. When one keyocode is sent,
|

lower byte is 0xFF.

Keycodes:
|
||||
Scancode consists of 7bit keycode and 1bit release flag.
|
||||
Device can send two keycodes at once. If just one keycode is sent
|
||||
keycode1 contains it and keyocode2 is 0xFF.
|
||||
|
||||
Power switch:
|
||||
You can read the state from PSW line(active low) however
|
||||
the switch has a special scancode 0x7F7F, so you can
|
||||
also read from Data line. It uses 0xFFFF for release scancode.
|

|

Keyboard LEDs & state of keys(Register2)
|
||||
This register hold current state of three LEDs and nine keys.
|

The state of LEDs can be changed by sending Listen command.

|

Signaling
|
||||
---------
|
||||
CLOCK is always from KEYBOARD. DATA are sent with MSB first.
|
||||
|
||||
1) IDLE: both lines are high.
|
||||
CLOCK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
DATA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
2) KEYBOARD->HOST: HOST reads bit on rising edge.
|
||||
CLOCK ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~
|
||||
DATA ~~~~~~~~~~~~X777777X666666X555555X444444X333333X222222X111111X000000X~~~~~~~
|
||||
<--> 160us(clock low)
|
||||
<---> 180us(clock high)
|
||||
|
||||
3) HOST->KEYBOARD: HOST asserts bit on falling edge.
|
||||
CLOCK ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~

<----> 840us(request to send by host) <---> 80us(hold DATA)
|
||||
<--> 180us(clock low)
|
||||
<---> 220us(clock high)
|
||||
|
||||
|
||||
Protocol
|
||||
--------
|
||||
COMMAND:
|
||||
Inquiry 0x10 get key event with block
|
||||
Instant 0x12 get key event
|
||||
Model 0x14 get model number(M0110 responds with 0x09)
|
||||
bit 7 1 if another device connected(used when keypad exists?)
|
||||
bit4-6 next device model number
|
||||
bit1-3 keyboard model number
|
||||
bit 0 always 1
|
||||
Test 0x16 test(ACK:0x7D/NAK:0x77)
|
||||
|
||||
KEY EVENT:
|
||||
bit 7 key state(0:press 1:release)
|
||||
bit 6-1 scan code(see below)
|
||||
bit 0 always 1
|
||||
To get scan code use this: ((bits&(1<<7)) | ((bits&0x7F))>>1).
|
||||
|
||||
Note: On the M0110A, Keypad keys and Arrow keys are preceded by 0x79.
|
||||
Moreover, some Keypad keys(=, /, * and +) are preceded by 0x71 on press and 0xF1 on release.
|
||||
|
||||
ARROW KEYS:
|
||||
Arrow keys and Calc keys(+,*,/,= on keypad) share same byte sequence and preceding byte of
|
||||
Calc keys(0x71 and 0xF1) means press and release event of SHIFT. This causes a very confusing situation,
|
||||
it is difficult or impossible to tell Calc key from Arrow key plus SHIFT in some cases.
|
||||
|
||||
Raw key events:
|
||||
press release

||||
