Following information obtained from Tomi Engdahl (then@delta.hut.fi),

Microsoft serial mouse
|
||||
|
||||
Serial data parameters:
|
||||
1200bps, 7 databits, 1 stop-bit
|
||||
|
||||
Data packet format:
|
||||
Data packet is 3 byte packet. It is send to the computer every time mouse
|
||||
state changes (mouse moves or keys are pressed/released).
|
||||
D7 D6 D5 D4 D3 D2 D1 D0
|
||||
1. X 1 LB RB Y7 Y6 X7 X6
|
||||
2. X 0 X5 X4 X3 X2 X1 X0
|
||||
3. X 0 Y5 Y4 Y3 Y2 Y1 Y0
|
||||
|
||||
Note: The bit marked with X is 0 if the mouse received with 7 databits
|
||||
and 2 stop bits format. It is also possible to use 8 databits and 1 stop
|
||||
bit format for receiving. In this case X gets value 1. The safest thing
|
||||
to get everything working is to use 7 databits and 1 stopbit when
|
||||
receiving mouse information (and if you are making mouse then send out
|
||||
7 databits and 2 stop bits).
|
||||
The byte marked with 1. is send first, then the others. The bit D6 in
|
||||
the first byte is used for syncronizing the software to mouse packets
|
||||
if it goes out of sync.
|
||||
|
||||
LB is the state of the left button (1 means pressed down)
|
||||
RB is the state of the right button (1 means pressed down)
|
||||
X7-X0 movement in X direction since last packet (signed byte)
|
||||
Y7-Y0 movement in Y direction since last packet (signed byte)
|
||||
|
||||
Mouse identification
|
||||
When DTR line is toggled, mouse should send one data byte containing
|
||||
letter 'M' (ascii 77).
|
||||
|
||||
|
||||
Logitech serial mouse
|
||||
|
||||
Logitech uses the Microsoft serial mouse protocol in their mouses (for
|
||||
example Logitech Pilot mouse and others). The origianal protocol supports
|
||||
only two buttons, but logitech as added third button to some of their
|
||||
mouse models. To make this possible logitech has made one extension to
|
||||
the protocol.
|
||||
I have not seen any documentation about the exact documents, but here is
|
||||
what I have found out: The information of the third button state is sent
|
||||
using one extra byte which is send after the normal packet when needed.
|
||||
Value 32 (dec) is sent every time when the center button is pressed down.
|
||||
It is also sent every time with the data packet when center button is kept
|
||||
down and the mouse data packet is sent for other reasons. When center
|
||||
button is released, the mouse sends the normal data packet followed by
|
||||
data bythe which has value 0 (dec). As you can see the extra data byte
|
||||
is sent only when you mess with the center button.
|
||||
|
||||

||||

|
||||
5. Y7' Y6' Y5' Y4' Y3' Y4' Y1' Y0'
|
||||
|
||||
LB is left button state (0 = pressed, 1 = released)
|
||||
CB is center button state (0 = pressed, 1 = released)
|
||||
RB is right button state (0 = pressed, 1 = released)
|
||||
X7-X0 movement in X direction since last packet in signed byte
|
||||
format (-128..+127), positive direction right
|
||||
Y7-Y0 movement in Y direction since last packet in signed byte
|
||||
format (-128..+127), positive direction up
|
||||
X7'-X0' movement in X direction since sending of X7-X0 packet in
|
||||
signed byte format (-128..+127), positive direction right
|
||||
Y7'-Y0' movement in Y direction since sending of Y7-Y0 packet in
|
||||
signed byte format (-128..+127), positive direction up
|
||||
|
||||
The last two bytes in the packet (bytes 4 and 5) contains information
|
||||
about movement data changes which have occured after data bytes 2 and 3
|
||||
have been sent.
