+Alternative Controller for HHKB Pro
+===================================
+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.
+
+This controller can work with HHKB **Professional**, **Professional** 2, **JP** and **Type-S**.
+
+See [this thread][AltController] in geekhack.org.
+
+[HHKB]: http://www.pfu.fujitsu.com/hhkeyboard/
+[AltController]: http://geekhack.org/index.php?topic=12047.0
+
+
+## Update
+* Bluetooth module RN-42 is supported.(2015/01)
+* V-USB and iWRAP are no longer supported now, but still it'll works with a little fix. See not_supported directory.(2015/01)
+
+
+##Features
+* Customizable keymap
+* More keymap layers(more Fn keys)
+* Mouse keys
+* USB NKRO
+* Bluetooth(RN-42)
+
+See README of [tmk_keyboard] for more.
+
+[tmk_keyboard]: http://github.com/tmk/tmk_keyboard
+
+###Pros
+* No risks: Everything is all reversible
+* No need for PCB trace patching, case cutting or any other destructive mod
+* Can keep original controller intact
+* Can change all HHKB behavior as you like
+
+###Cons
+* Void your warranty
+* Lose USB hub function of Pro2
+
+##DISCLAIMER
+I'm not a professional of electronics nor MCU programming. This may damage your HHKB.
+And my English writing is poor, I'm not sure I can convey my notions accurately.
+
+
+##Documents
+See [doc/HHKB.txt](doc/HHKB.txt) and files under [doc/](doc/) for internal of HHKB and this controller.
+
+
+##Build Firmware & Program
+See [this document](../../doc/build.md) first.
+
+### Configuration
+If your target is **HHKB JP** you need to set `HHKB_JP` build option in `Makefile` or use `Makefile.jp` instead of `Makefile`.
+
+If you use other than **TMK Alt Controller Board** set proper `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`. At least PJRC Teensy requires changing `BOOTLOADER_SIZE` to 512.
+
+### Build
+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. Just `make` with `KEYMAP` option like:
+
+ $ make -f Makefile.<jp|pjrc|rn42> KEYMAP=(hasu|hhkb|spacefn|<name>)
+
+You can omit `-f` option when you use `Makefile`. `Makefile` is used for **Pro2 and Pro**, `Makefile.jp` fits for **JP** model and `Makefile.rn42` supports Bluetooth module **RN-42**. `Makefile.pjrc` uses **PJRC** as output protocol instead of **LUFA**.
+
+
+### Program
+First, push reset button on board to start bootloader.
+
+This command programs the controller with [dfu-programmer] if the tool is installed and configured properly.
+
+ $ make -f Makefile.<variant> KEYMAP=<name> dfu
+
+Or you can also use [FLIP] command to program. Also the tool should be installed and configured properly. FLIP GUI application is also available.
+
+ $ make -f Makefile.<variant> KEYMAP=<name> flip
+
+Use [Teensy Loader] if your controller is Teensy/Teensy++.
+
+
+##Keymap
+To define your own keymap create file named `keymap_<name>.c` and see [keymap document](../../doc/keymap.md) and existent keymap files.
+
+
+##Hardware
+You have some options for hardware. Development boards with USB AVR family(ATMega32U4, AT90USB1286) like Teensy will work while MegaAVR with [V-USB] library is also cheaper option for DIY.
+
+###1. TMK Alt Controller Board
+Design files are available at [Keyboard Controller Board for HHKB(KiCad project)](https://github.com/tmk/HHKB_controller) and see [Controller Distribution thread](http://geekhack.org/index.php?topic=56494.0) if you get an assembled one.
+
+
+###2. PJRC Teensy
+See [this thread](http://geekhack.org/index.php?topic=57008.0).
+
+
+###3. V-USB version
+See [V-USB controller for HHKB](doc/V-USB.md).

+Internal of HHKB pro
+=====================
+HHKB pro has MCU and some chips on separate two PCBs.
+
+Controller PCB
+--------------
+ M38K07M4 Renesas MCU with USB function
+ http://documentation.renesas.com/eng/products/mpumcu/rej03b0192_38k0ds.pdf
+

+
+Keyswitch PCB
+-------------
+ HC4051 Analog Multiplexer: select a row line.
+ http://www.ti.com/lit/ds/schs122j/schs122j.pdf
+ LS145 BCD Decoder: select a column line.
+ http://www.ti.com/lit/ds/symlink/sn74ls145.pdf
+ BU9831 Non-volatile electronic potentiometer: for calibration?
+ https://www.spezial.com/doc/rohm-a/bu9831.pdf
+ TP1683/4 Capacitive Sensing controller: no datasheet available.
+
+ (HHKB_keyswitch.jpg)

+ Topre original chip?
+ (HHKB_TP1684.jpg)
+
+
+Connector Cable
+---------------
+Two PCBs are connected by 15 lines(13 in case of Pro2).
+Vcc and GND use 3(2) lines each, other lines are for keyboard signaling.
+

+
+ NOTE: guessing pin5(KEY_PREV) may work for hysteresis of capacitive sensing.
+ NOTE: 1KOhm didn't work as pullup resistor on KEY. AVR internal pullup or 10KOhm resistor was OK.
+ NOTE: JP has two HC4051(Z2,Z3) and line 5, 6 and 7 are connected to both of them.

+Signals charts
+--------------
+ While pressing space bar, watched HHKB Pro 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. A key is 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).
+
+ (HHKB_chart2.jpg)

+ 3) Wait 5us after column select, then set prev, strobe colD to spit out key status and read it.
+ prev _~~~~_____ 20us if previous key state is low
+ colD ~~~__~~~~~ 10us strobe
+ key ~~~____~~~ 22us indicates current state of the key
+
+ NOTE: JP scans twice fast as Pro/Pro2 does. So Pro/Pro2 scans 8x8 matrix in 15.4ms while JP scans 16x8 in that time.

+TROUBLE SHOOT
+-------------
+07/16 After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
+ Found R8 had wrong 1K resistor and changed to 10K, after that it can send to the module again. Not sure how it had sent with the wrong 1K before.
+
+07/18 On Linux, had an USB related trouble; keyboard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.
+
+12/07 rn42_rts() read 1 every time. R12 broke in open mode(no coductive), idk why, too much heat with soldering? and PF1 pin was not soldered.
+ It resolved with resoldering PF1 and new resistor on R12.
+
+
+
+

+RN-42 Bluetooth Module Support
+==============================
+Bluetooth controller board works with HHKB Pro2, JP, Type-S and Type-S JP and it supports both USB and Bluetooth as keyboard output protocol. Bluetooth module Roving Networks/Microchip RN-42 is installed on the board.
+
+
+RN-42:
+http://www.microchip.com/wwwproducts/Devices.aspx?product=RN42
+
+
+Capabitlities:
+- USB keyboard functions
+ completely equivarent to USB controller including mouse keys and NKRO.
+- Switching between USB and Bluetooth
+ You can switch the two connections with BT switch or key combination.
+- RN-42 config mode
+ You can change power/connection configuration of the module if needed.
+- Low battery alert
+ Red LED turns on when low voltage.
+- RN-42 status indicator
+ LED indicates status of Bluetooth connection.
+- Pairing
+ The module stores up to 8 connections.
+- Auto connect
+ The module connects the last connected device automatically.
+- iOS support
+ works as keyboard with iPhone5. No tested completely.
+- Android support
+ works as keyboard and mouse with Nexus5. No tested completely.
+- Mouse keys over BT
+ Note that iOS doesn't accept mouse device.
+
+
+Limitations:
+- Short battery life
+ Around 12hr with 1000mAh
+- No connection switching
+ RN-42 auto-connects to the last connected device.
+ Some of consumer products can switch between devices, for example Logitech K480.
+ http://www.logitech.com/en-us/product/multi-device-keyboard-k480?crid=26
+- HHKB JP requires case modification for BT switch and LEDs.
+ without switch power controlled by MCU? Probably using 3.3V regulator enable pin power of RN-42 can be controlled.
+
+NOTE:
+- LIPO BATTERY IS VERY DANGEROUS, TAKE EXTRA CARE OF YOUR SAFETY AND PROPERTY.
+- RN-42 version 6.15 is supported.
+- No NKRO over Bluetooth
+- Check you country's wiress regulation and certification of RN-42.

+Switch to USB mode
+------------------
+You can switch between USB and Bluetooth with pressing 'LShift+RShift+u'.
+
+
+Pairing mode
+------------
+This disconnects current connect and enter pairing mode.
+
+
+
+
+For deveropment
+===============
+
+RN-42 Serial Connection
+-----------------------
+UART: 115200bps, 8bit, 1-stopbit, non-parity, no flow control
+SSP: 115200bps, 8bit, 1-stopbit, non-parity, no flow control(via Bluetooth)
+
+To enter command mode disconnect the module from host and type '$$$'.(you will see 'CMD') and type '+' to get local echo. To exit type '---'(you will see 'END').
+
+
+RN-42 Commands
+--------------
+S-,tmkBT // Device name
+SS,keyboard/mouse // service name
+SM,4 // Auto Connect DTR mode
+SW,8010 // Sniff enable 0x10*0.625ms=10ms; 50ms is laggish and not much power save
+S~,6 // HID profile
+S~,0 // SPP profile
+SH,003C // HID register
+SY,0004 // Transmit power
+SC,0000 // COD: 000005C0 (see HID spec/Bluegiga doc)
+SD,05C0 // bit 12-8 7 6 5-0
+ // 00101 1 1 0
+ // peripheral pointing keybaord joystick, gamepad, ...
+SM,6 // Pairing mode: auto connect
+SM,4 // Master mode: Connection can be controled with GPIO6
+SF,1 // Factroy reset
+R,1 // reboot
+SR,Z // removes all remote addresses for reconnecting.
+ // can be used to connect another host
+SR,I // registers last inquiry address
+
+
+Operation Modes
+---------------
+SM,3 Auto Connect Master mode
+SM,4 Auto Connect DTR Mode uses GPIO6 to make and break connection(Mode =DTR)
+ confirm: auto connect works and control connection with GPIO6
+SM,5 Auto Connect ANY Mode (Mode =ANY)
+ each time GPIO is set, make inquiry and connect to the first found device
+SM,6 automatically reconnect(Mode =Pair)
+ confirm: auto connect works well but difficult to enter command mode.

+
+Apple iOS
+---------
+Keyboard can be used with iPhone, but mouse cannot.
+
+
+Android
+-------
+3.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.
+
+
+Power Management
+----------------
+Inquiry and Page window Idle or Active (3.1.1)
+ Downside: delay in discovery or connection time
+ SI, // set inquiry scan window(discovery) on/off duty?
+ SJ, // set page scan window(connection)
+ This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
+
+Sniff mode Transmit
+ Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
+ In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
+ SW,<val> // set interval timer(*0.625ms) 0000-7FFF
+
+Deep sleep Idle (3.1.2)
+ In this mode the module shuts down completly and only draws about 300uA. To enable this set the most signifant bit(0x8000) of Sniff interaval timer.
+ SW,8320 // deep sleep enable(interval=0x320*0.625=500ms)
+ In normal sleep the firmware is still running in idle mode, and wakes up about 20 times per second to check ports, update LEDs, etc. During deep sleep, the firmware actually stops runnig some tasks and the LEDs only update about once per second.
+ To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
+ *send a charactor to the UART(first charactor will be lost)
+ *toggle CTS low to high and wait 5ms
+ *wake automatically every slot time(<val>*0.625ms)
+ Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
+ Downside: latency and data loss
+
+Disable Output driver Idle or Active (3.1.3)
+ S%,1000 // set all GPIO pins(0-11) to inputs.
+
+Lower Transmit Power Idle or Active (3.1.4)
+ SY,<hex> // transmit power setting(takes effect after a power cycle and reboot)
+ Downside: reducing effective range
+
+
+Optimizig for Latency
+---------------------
+By default the firmware is optimized for throughput.
+SQ,16 // set latency bit
+SQ,0 // unset latency bit
+
+
+Configuration timer settings
+----------------------------
+Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
+
+The module has remote configuration timer to allow remote configuration over Bluetooth after power up in Slave mode. In Master modes the remote configuration timer is set to 0(no remote configuration). (In Trigger Master mode the timer is used as an idle timer to break the connection after time expires with no charactors receive.)
+ ST,0 // no remote, no local when connected
+ ST,<1-252> // local and remote with timeout in seconds from power up
+ ST,253 // local only without timeout
+ ST,254 // remote only without timeout
+ ST,255 // local and remote without timeout
+
