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.

|
|
<--> 160us(clock low)
|

3) HOST->KEYBOARD: HOST asserts bit on falling edge.

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
|
