ALPS HID Touchpad Protocol
|
||||
----------------------
|
||||
|
||||
Introduction
|
||||
------------
|
||||
Currently ALPS HID driver supports U1 Touchpad device.
|
||||
|
||||
U1 devuce basic information.
|
||||
Vender ID 0x044E
|
||||
Product ID 0x120B
|
||||
Version ID 0x0121
|
||||
|
||||
|
||||
HID Descriptor
|
||||
------------
|
||||
Byte Field Value Notes
|
||||
0 wHIDDescLength 001E Length of HID Descriptor : 30 bytes
|
||||
2 bcdVersion 0100 Compliant with Version 1.00
|
||||
4 wReportDescLength 00B2 Report Descriptor is 178 Bytes (0x00B2)
|
||||
6 wReportDescRegister 0002 Identifier to read Report Descriptor
|
||||
8 wInputRegister 0003 Identifier to read Input Report
|
||||
10 wMaxInputLength 0053 Input Report is 80 Bytes + 2
|
||||
12 wOutputRegister 0000 Identifier to read Output Report
|
||||
14 wMaxOutputLength 0000 No Output Reports
|
||||
16 wCommandRegister 0005 Identifier for Command Register
|
||||
18 wDataRegister 0006 Identifier for Data Register
|
||||
20 wVendorID 044E Vendor ID 0x044E
|
||||
22 wProductID 120B Product ID 0x120B
|
||||
24 wVersionID 0121 Version 01.21
|
||||
26 RESERVED 0000 RESERVED
|
||||
|
||||
|
||||
Report ID
|
||||
------------
|
||||
ReportID-1 (Input Reports) (HIDUsage-Mouse) for TP&SP
|
||||
ReportID-2 (Input Reports) (HIDUsage-keyboard) for TP
|
||||
ReportID-3 (Input Reports) (Vendor Usage: Max 10 finger data) for TP
|
||||
ReportID-4 (Input Reports) (Vendor Usage: ON bit data) for GP
|
||||
ReportID-5 (Feature Reports) Feature Reports
|
||||
ReportID-6 (Input Reports) (Vendor Usage: StickPointer data) for SP
|
||||
ReportID-7 (Feature Reports) Flash update (Bootloader)
|
||||
|
||||
|
||||
Data pattern
|
||||
------------
|
||||
Case1 ReportID_1 TP/SP Relative/Relative
|
||||
Case2 ReportID_3 TP Absolute
|
||||
ReportID_6 SP Absolute
|
||||
|
||||
|
||||
Command Read/Write
|
||||
------------------
|
||||
To read/write to RAM, need to send a commands to the device.
|
||||
The command format is as below.
|
||||
|
||||
DataByte(SET_REPORT)
|
||||
Byte1 Command Byte
|
||||
Byte2 Address - Byte 0 (LSB)
|
||||
Byte3 Address - Byte 1
|
||||
Byte4 Address - Byte 2
|
||||
Byte5 Address - Byte 3 (MSB)
|
||||
Byte6 Value Byte
|
||||
Byte7 Checksum
|
||||
|
||||
Command Byte is read=0xD1/write=0xD2 .
|
||||
Address is read/write RAM address.
|
||||
Value Byte is writing data when you send the write commands.
|
||||
When you read RAM, there is no meaning.
|
||||
|
||||
DataByte(GET_REPORT)
|
||||
Byte1 Response Byte
|
||||
Byte2 Address - Byte 0 (LSB)
|
||||
Byte3 Address - Byte 1
|
||||
Byte4 Address - Byte 2
|
||||
Byte5 Address - Byte 3 (MSB)
|
||||
Byte6 Value Byte
|
||||
Byte7 Checksum
|
||||
|
||||
Read value is stored in Value Byte.
|
||||
