1 Alternative Controller for HHKB Pro
2 ===================================
3 I wanted to add some features like vi cursor and mouse keys to my [HHKB][HHKB] but its controller is not programmable and firmware source code is not open, of course. This means customizing this keyboard needs to replace original controller with programmable one.
5 This controller can work with HHKB **Professional**, **Professional 2**, **JP** and **Type-S**.
7 See [this thread][AltController] in geekhack.org for details.

14 * Bluetooth module RN-42 is supported.(2015/01)
19 * More keymap layers(more Fn keys)
24 See README of [tmk_keyboard] for more.

29 * No risks: Everything is all reversible
30 * No need for PCB trace patching, case cutting or any other destructive mod
31 * Can keep original controller intact
32 * Can change all HHKB behavior as you like
36 * Lose USB hub function of Pro2
39 I'm not a professional of electronics nor MCU programming. This may damage your HHKB.
40 And my English writing is poor, I'm not sure I can convey my notions accurately.
42 ## Quick-Start Guide for TMK Alt Controller
43 1. Build a custom keyboard layout using the online tool
44 * Use Chrome if the site does not behave as expected
45 * Make sure to generate the file using the right template
47 * [Bluetooth](http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?hhkb_rn42)
48 * [USB-only](http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?hhkb)
51 * [Bluetooth](http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?hhkb_jp_rn42)
52 * [USB-only](http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?hhkb_jp)
54 1. Save the `.hex` file to your computer; note this is all you need to generate
55 a custom layout with most of the available features (including mouse control)
56 * Check-out [the last third of this video](https://www.youtube.com/watch?v=TYmAb8zOPWU&t=561s)
57 to get an idea of how to build your own layout; it includes how to load to the firmware using FLIP<P>
60 1. Download and install the `dfu-programmer` (the alternative to FLIP), open-source available
61 for Windows, Linux, and Mac OS. e.g., for Mac OS: `brew install dfu-programmer` <P>
62 _Note: This bootloader is all that is required to load/flash the firmware created
63 using the online tool. You do not need the full `avr-gcc` development stack
64 because you created the required `.hex` file using the online tool instead._
66 1. Please read and understand this next step in full before running the
67 following three commands
70 dfu-programmer atmega32u4 erase --force
71 dfu-programmer atmega32u4 flash <your_downloaded_file>.hex
72 dfu-programmer atmega32u4 launch
75 Or if your are on Unix-like shell you can use command sequence concatinated with `&&`
79 dfu-programmer atmega32u4 erase --force && \
80 dfu-programmer atmega32u4 flash <your_downloaded_file>.hex && \
81 dfu-programmer atmega32u4 launch
84 * Run commands from the directory where you saved your `.hex` file
85 * Put controller into programmable mode(bootloader) by hitting the red button located on your controller
86 * Once in this mode, you will no longer have access to your HHKB, you need other keyboard to input the commands or mouse to copy and paste.
87 * `erase` clears existent firmware on flash memory
88 * `flash` loads new firmware you downloaded
89 * `launch` restarts keyboard
90 * See `man dfu-programmer` for details
91 * Replug controller and redo the process when you are in trouble
93 * `sleep 20` gives you time to switch your controller to a programmable mode
94 These commands execute automatically once the ~ 20 seconds have passed.
98 See [doc/HHKB.txt](doc/HHKB.txt) and files under [doc/](doc/) for internal of HHKB and this controller.
101 ## Build Firmware & Program
102 See [this document](../../tmk_core/doc/build.md) and [this](https://github.com/tmk/tmk_keyboard/wiki#build-firmware) first.
105 Build options and firmware settings are available in `Makefile` and `config.h` or `config_rn42.h`.
109 To define your own keymap create file named `keymap_<name>.c` and see [keymap document](../../tmk_core/doc/keymap.md) and existent keymap files.
113 Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. Just `make` with `KEYMAP` option like:
115 $ make -f Makefile.<variant> KEYMAP=<name> clean
116 $ make -f Makefile.<variant> KEYMAP=<name>
118 `Makefile` can be used for **Pro2 and Pro** USB controller, `Makefile.jp` for **JP**, `Makefile.rn42` for **Pro2** Bluetooth and `Makefile.rn42.jp` for **JP** Bluetooth.
122 First, push reset button on board to start bootloader.
124 This command programs the controller with [dfu-programmer] if the tool is installed and configured properly.
126 $ make -f Makefile.<variant> KEYMAP=<name> dfu
128 Or you can also use [FLIP] command to program. Also the tool should be installed and configured properly. FLIP GUI application is also available.
130 $ make -f Makefile.<variant> KEYMAP=<name> flip
136 ### TMK Alt Controller Board
137 Preassmbled controller is available from [here](https://geekhack.org/index.php?topic=71517.0).
139 You can find design files of the controller at [Keyboard Controller Board for HHKB(KiCad project)](https://github.com/tmk/HHKB_controller).
