* Finger Sensing Pad Intellimouse Mode(scrolling wheel, 4th and 5th buttons)
|
||||
==============================================================================
|
||||
A) MSID 4: Scrolling wheel mode plus Forward page(4th button) and Backward
|
||||
page (5th button)
|
||||
@1. Set sample rate to 200;
|
||||
@2. Set sample rate to 200;
|
||||
@3. Set sample rate to 80;
|
||||
@4. Issuing the "Get device ID" command (0xF2) and waits for the response;
|
||||
@5. FSP will respond 0x04.

* Programming Sequence for Determining Packet Parsing Flow
|
||||
==============================================================================
|
||||
1. Identify FSP by reading device ID(0x00) and version(0x01) register
|
||||
|
||||
2. Determine number of buttons by reading status2 (0x0b) register
|
||||
|
||||
buttons = reg[0x0b] & 0x30
|
||||
|
||||
if buttons == 0x30 or buttons == 0x20:
|
||||
# two/four buttons
|
||||
Refer to 'Finger Sensing Pad PS/2 Mouse Intellimouse'
|
||||
section A for packet parsing detail(ignore byte 4, bit ~ 7)
|
||||
elif buttons == 0x10:
|
