Alternative Controller for HHKB pro
|
||||
===================================
|
||||
I want to add vi cursor and mouse keys to HHKB. Original HHKB controller is not programmable and
|
||||
firmware source code is not open. So, customizing HHKB needs to replace original controller with programmable one.
|
||||
I used Teensy++ as alternative controller. Though a Teensy has enough ports to drive HHKB,
|
||||
Teensy++ has clean pinout and it makes programing and wiring easier.
|
||||
|
||||
This is just a proof of concept for replacing controller of HHKB, not a complete firmware.
|
||||
|
||||
My prototype firmware source tree is here:
|
||||
branch: hhkb(http://github.com/tmk/tmk_keyboard/tree/hhkb)
|
||||
This firmware is a port of my previous project:
|
||||
HHKB style Mod(http://geekhack.org/showwiki.php?title=Island:11930)
|
||||
PJRC:
|
||||
Teensy++/Teensy(http://www.pjrc.com/teensy/)
|
||||
|
||||
|
||||
Pros:
|
||||
* without pattern cutting, case mod and soldering
|
||||
* can keep original controller intact
|
||||
* can change HHKB behaviour as you like(by C programming)
|
||||
|
||||
Cons:
|
||||
* void your warranty
|
||||
* unavailability of Teensy++/Teensy(because of PS3 cracking boom?)
|
||||
|
||||
Features:
|
||||
* customized keymap
|
||||
* more keymap layers
|
||||
* mouse keys for minimum mouse operation(never comfortable for normal use)
|
||||
* and more...(in the future)
|
||||
|
||||
Any suggestions or ideas are welcome.
|
||||
|
||||
|
||||
NOTE:
|
||||
My HHKB is just "Professional". This means followings may not be applied to "Professional2".
|
||||
|
||||
DISCLAIMER:
|
||||
I'm not a professional for electronics and MCU programming. This may damage your HHKB.
|
||||
And my English writing is poor, I'm not sure I can convey my notions accurately.

Signals charts:
|
||||
While pressing space bar, watched HHKB original controller signals by logic analyzer.
|
||||
Row and column is looping between 0-7 each for selecting a key.
|
||||
A key is scaned every about 15ms, so scan rate is 66Hz.
|
||||
|
||||
(HHKB_chart1.jpg)
|
||||
|
||||
Space bar locate at ROW:3 COL:7. Key are selected by HC4051(C,B,A) and LS145(C,B,A).
|
||||
Key state can be read on TP1684(4/KEY) while asserting low on LS145(D).
|
||||
Usage of TP1684(5) is unknown. Key state can be read without using this signal.
|
||||
|
||||

Matrix scan pseudo code:
|

|

SELECT_ROW(row); // set HC4051(A,B,C)
|
||||

||||
for (col: 0-7) {
