|

Bit3 => Always 1, as specified by PS/2 protocol.
|
|
Bit2 => Finger index, 0 is the first finger, 1 is the second finger.
|
|
If bit 1 and 0 are all 1 and bit 4 is 0, the middle external
|

Bit1 => Right Button, 1 is pressed, 0 is not pressed.

Byte 2: X coordinate (xpos[9:2])

Byte 3: Y coordinate (ypos[9:2])

Bit6 => scroll left button

|
|
|
|
When one of the two fingers is up, the device will output four consecutive
|
|
MFMC#0 report packets with zero X and Y to represent 1st finger is up or
|
|
four consecutive MFMC#1 report packets with zero X and Y to represent that
|
|
the 2nd finger is up. On the other hand, if both fingers are up, the device
|
|
will output four consecutive single-finger, absolute coordinate(SFAC) packets
|
|
with zero X and Y.

* Programming Sequence for Page Register Reading/Writing
|
|
==============================================================================
|
|
|
|
In order to overcome the limitation of maximum number of registers
|
|
supported, the hardware separates register into different groups called
|
|
'pages.' Each page is able to include up to 255 registers.
|
|
|
|
The default page after power up is 0x82; therefore, if one has to get
|
|
access to register 0x8301, one has to use following sequence to switch
|
|
to page 0x83, then start reading/writing from/to offset 0x01 by using
|
|
the register read/write sequence described in previous section.
|
|
|
|
Page register reading sequence:
|
|
|
|
1. send 0xf3 PS/2 command to FSP;
|
|
|
|
2. send 0x66 PS/2 command to FSP;
|
|
|
|
3. send 0x88 PS/2 command to FSP;
|
|
|
|
4. send 0xf3 PS/2 command to FSP;
|
|
|
|
5. send 0x83 PS/2 command to FSP;
|
|
|
|
6. send 0x88 PS/2 command to FSP;
|
|
|
|
7. send 0xe9(status request) PS/2 command to FSP;
|
|
|
|
8. the response read from FSP should be the requested page value.
|
|
|
|
Page register writing sequence:
|
|
|
|
1. send 0xf3 PS/2 command to FSP;
|
|
|
|
2. send 0x38 PS/2 command to FSP;
|
|
|
|
3. send 0x88 PS/2 command to FSP;
|
|
|
|
4. send 0xf3 PS/2 command to FSP;
|
|
|
|
5. if the page address being written is not required to be
|
|
inverted(refer to the 'Register inversion requirement' section),
|
|
goto step 6
|
|
|
|
5a. send 0x47 PS/2 command to FSP;
|
|
|
|
5b. send the inverted page address to FSP and goto step 9;
|
|
|
|
6. if the page address being written is not required to be
|
|
swapped(refer to the 'Register swapping requirement' section),
|
|
goto step 7
|
|
|
|
6a. send 0x44 PS/2 command to FSP;
|
|
|
|
6b. send the swapped page address to FSP and goto step 9;
|
|
|
|
7. send 0x33 PS/2 command to FSP;
|
|
|
|
8. send the page address to FSP;
|
|
|
|
9. the page register writing sequence is completed.

* Gesture ID
|
|
==============================================================================
|
|
|
|
Unlike other devices which sends multiple fingers' coordinates to host,
|
|
FSP processes multiple fingers' coordinates internally and convert them
|
|
into a 8 bits integer, namely 'Gesture ID.' Following is a list of
|
|
supported gesture IDs:
|
|
|
|
ID Description
|
|
0x86 2 finger straight up
|
|
0x82 2 finger straight down
|
|
0x80 2 finger straight right
|
|
0x84 2 finger straight left
|
|
0x8f 2 finger zoom in
|
|
0x8b 2 finger zoom out
|
|
0xc0 2 finger curve, counter clockwise
|
|
0xc4 2 finger curve, clockwise
|
|
0x2e 3 finger straight up
|
|
0x2a 3 finger straight down
