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.
