This is keyboard firmware for PFU HHKB style keyboard and Teensy/Teensy++ 2.0. This is keyboard firmware for AVR USB MCUs or Teensy/Teensy++ 2.0.
OS see this as composite device which has keyboard and mouse.

It works as normal keyboard.
It is for modified Macway keyboard(TP-999KB-E).

keyboard has mouse key now.
keyboard with layers.(see keymap.c)

ghost
matrix
mechanical with diodes
membrane
OS Support Status
-----------------
NKRO is possible at least relatively new OS.
Following OS supports both Extended and Bitmarp report.
Windows7 64bit
Windows2000 SP4
Ubuntu 10.4(Linux 2.6)
USB NKRO methods
----------------
1. Virtual keyboards
Keyboard can increase its KRO by using virtual keyboards with Standard or Extended report.
If the keyboard has 2 virtul keyboard with Standard report(6KRO), it gets 12KRO.
Using this method means the keyboard is a composite device.
2. Exteded report
It needs large report size for this method to achive NKRO.
If a keyboard has 101keys, it needs 103byte report. It seems to be inefficient.
3. Bitmap report
If the keyboard has less than 128keys, 16byte report will be enough for NKRO.
The 16byte report seems to be reasonable cost to get NKRO.
Report Format
-------------
Other report formats than followings are possible, though these format are typical one.
1. Standard 8bytes
modifiers(bitmap) 1byte
reserved 1byte(not used)
keys(array) 1byte*6
Standard report can send 6keys plus 8modifiers simultaneously.
Standard report is used by most keyboards in the marketplace.
Standard report is identical to boot protocol report.
Standard report is hard to suffer from compatibility problems.
2. Extended standard 16,32,64bytes
modifiers(bitmap) 1byte
reserved 1byte(not used)
keys(array) 1byte*(14,32,62)
Extended report can send N-keys by using N+2bytes.
Extended report is expected to be compatible with boot protocol.
3. Bitmap 16,32,64bytes
keys(bitmap) (16,32)bytes
Bitmap report can send at most 128keys by 16bytes and 256keys by 32bytes.
Bitmap report can achieve USB NKRO efficiently in terms of report size.
Bitmap report needs a deliberation for boot protocol implementation.
Compatibility Problem
---------------------
Some BIOS doesn't send SET_PROTCOL request, a keyboard can't switch to boot protocol mode.
This may cuase a problem on a keyboard which uses other report than Standard.
Windows Problem
---------------
1. Windows accepts only 6keys in case of Standard report.
It should be able to send 6keys plus 8modifiers.
2. Windows accepts only 10keys in case of 16bytes Extended report.
It should be able to send 14keys plus 8modifiers.
3. Windows accepts only 18keys in case of 32bytes Extended report.
It should be able to send 30keys plus 8modifiers.
If keys are pressed in excess of the number, wrong keys are registered on Windows.
This problem will be reportedly fixed soon.(2010/12/05)
