+The Ghost Squid controller
+==========================
+Custom controller for the Cooler Master QuickFire XT keyboard designed by bpiphany.
+
+*Note that this is not the official firmware*
+
+Build
+-----
+Move to this directory then just run `make` like:
+
+    $ make -f Makefile.lufa
+
+At the moment only the LUFA stack is supported.
+
+
+Bootloader
+---------
+To enter bootloader by hardware use a magnet above the controller before connecting the usb cable.
+
+It is still possible to use Boot Magic and Command (LSFT+RSFT+PAUS) to access the bootloader though.

+## 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)

 ### 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 KEYMAP=[hasu|hhkb|spacefn|<name>]
-    $ make -f Makefile.jp KEYMAP=[jp|<name>]        # for HHKB JP
+    $ 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

-    $ make -f Makefile.jp flip      # for HHKB JP
+    $ make -f Makefile.<variant> KEYMAP=<name> flip

 Use [Teensy Loader] if your controller is Teensy/Teensy++.

+Memo of deveopment
+==================
+just memo, NOT WORTH READING
+
+Bug:
+- Factory Reset PIO4 doesn't work
+    - the reason is unclear - 12/08 NOT LOOK INTO ANY MORE
+    - WORKAROUND: use serial pins(3.3V, GND, RX and TX)
+        - SF,1 and R,1 to set factory defalult
+    
+
+Todo:
+- LED cover and switch knob and new Slide Switch
+- RN42 auto configuration
+    - configure the module as HID device every time powering up
+    - this'll reduce work load of assembly
+
+- move rn42 to protocol directory when it becomes reusable stack
+
+- sendchar() in lufa.c no buffer
+    - no buffering. character lost can be caused.
+- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
+
+- BT operations
+    - disconnect
+    - new connection
+    - remove connection
+
+- sendchar() in lufa.c block loop   - DONE 11/29
+    - block loop when powered with AC adapter
+    - FrameNumber is not updated when adapter powered
+
+Improving:
+- ADC resolution
+    AVR120
+    AVR32138
+    - Enhancing ADC resolution by oversampling
+        AVR121  http://www.atmel.com/images/doc8003.pdf
+    - disable digital input buffer DIDR(7.8.6)
+
+Design:
+- suspend.h - DONE 11/26
+    - remove argument from suspend_power_down() for backward compatitibility
+- remove MCU dependent power saving code from core/keyboard - DONE 11/23
+    - it should be located in project matrix.c
+- HHKB matrix.c needs matrix_prev?
+    - is_modified() is obsolete now. really needs?
+- ADC: removing AREF capacitor C10
+    - seems to be better while usb powered
+    - still bad while battery powered
+    http://electronics.stackexchange.com/questions/105849/avcc-and-capacitor-using-adc
+- ADC: smaller resistors for voltage dividor
+    - 1K + 1K: not improved. - 11/27
+
+
+LUFA:
+USB connection check: state of USB deivce
+- USB_DeviceState:
+    USB_Deivce_State_t { Unattached, Powered, Default, Addressed, Configured*, Suspended* }
+    Unattached: unpluged
+    Powered:    pluged with power adapter
+    Default:    enumerate process bigin
+    Addressed:  addressed
+    Configured: enumerated
+    Suspended:  suspended
+
+- USB_IsInitialized: state of LUFA core setup
+    becomes true in USB_Init()  USBController_AVR8.c
+    becomes false in USB_Disable()  USBController_AVR8.c
+- USB_VBUS_GetStatus(): state of VBUS(power/connection)
+- USB_Disable() detaches, disables all interrupts, controller, PLL, regulater.
+
+- When connect to power adapter
+    - event happened: CW or CSW or C or DDC
+    - USB state: not configured
+
+- USB evnets
+    - USB connect: CSWRWRW
+    - USB connect but fail to enumeration: CWRWRWRWS
+    - USB disconnect: D
+    - Power adapter connect: CW, CSW, C
+    - Power adapter disconnect: D
+
+
+Power saving:
+- Pro2 current consumption
+    - active: 138.2mA(no device on Hub)
+    - suspended: 30.9mA(WakeUp enabled DIPSW6)
+    - suspended: 0mA->46.0mA(WakeUp disabled DIPSW6)
+- Pro current consumption
+    - active: 54.0mA
+    - suspended: 40.5mA(WakeUp enabled DIPSW6)
+    - suspended: 0.3mA(WakeUp disabled DIPSW6)
+
+- RN42 3.3V
+    - disconnected(Idle): 5mA (config mode)
+    - connected(Active):
+        SW,0000:  23-26mA
+        SW,0010:  27-29mA worse than 0000 for unknown reason
+        SW,0020:  17-19mA mouse NG
+        SW,0030:  13-16mA laggy mouse NG
+        SW,0050:  10-13mA laggy mouse NG
+
+- matrix power saving
+    - power saving while externally powered and not while unpluged
+- confirm suspend mode lufa.c: matrix_power_*, suspend_wakeup_condition
+- 8MHz clock
+- When not connected in a few minutes get into deep sleep to save battery life
+- CTS is needed for waking up from deep sleep? How deep sleep is activated?
+- firmware controlled 3.3V DC converter to switch on/off BT module
+- sleep MCU and BT module(keyboard is not used)
+- deep sleep MCU and BT module(keyboard is not used for long time)
+- deep sleep MCU and turn off BT module(keyboard is not used and not connected)
+- Battery ADC; switching, high resistance
+    - switching gnd end of divider with PF4
+    - high resistor 100K/1M?
+        capacitor   10nF
+        http://www.eevblog.com/forum/beginners/measuring-battery-voltage-without-consuming-current/
+- During USB suspend change clock source to internal RC from external Xtal(6.8)
+- FRZCLK: you can freeze clock for power saving. still WAKEUPI and VBUSTI interrupts are available while freezing.(21.7.3)
+- Suspend: Clear Suspend Bit, Freeze clock, disable PLL, MCU sleep(21.13)
+- Voltage reference(8.1.1)
+    - to reduce power consumption while power down mode
+- unset ADEN before sleep(24.7)

+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.

+---------
+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

-Roving RN-42
-============
-
-Bug:
- with Nexus5 keyboard and mouse are very laggy.
-
- lose USB connection during power-down mode
-    - USB initialize code in main() causes this - WRONG
-    - Do not power-down during USB connection is active - DONE 11/11
-        (USB_DeviceState == USB_DEVICE_Configured) is used to check USB connection
-        matrix_power_down() matrix.c - 11/23
-
-Todo:
-
-Design:
- remove MCU dependent power saving code from core/keyboard
-    - it should be located in project matrix.c - DONE 11/23
- HHKB matrix.c needs matrix_prev?
-    - is_modified() is obsolete now. really needs?
-
-
-LUFA:
-USB connection check: state of USB deivce
- USB_DeviceState:
-    USB_Deivce_State_t { Unattached, Powered, Default, Addressed, Configured*, Suspended* }
- USB_IsInitialized: state of LUFA core setup
-    becomes true in USB_Init()  USBController_AVR8.c
-    becomes false in USB_Disable()  USBController_AVR8.c
- USB_VBUS_GetStatus(): state of VBUS(power/connection)
- USB_Disable() detaches, disables all interrupts, controller, PLL, regulater.
-
-
-Power saving:
- confirm suspend mode lufa.c: matrix_power_*, suspend_wakeup_condition
- 8MHz clock
- When not connected in a few minutes get into deep sleep to save battery life
- CTS is needed for waking up from deep sleep? How deep sleep is activated?
- firmware controlled 3.3V DC converter to switch on/off BT module
- sleep MCU and BT module(keyboard is not used)
- deep sleep MCU and BT module(keyboard is not used for long time)
- deep sleep MCU and turn off BT module(keyboard is not used and not connected)
- Battery ADC; switching, high resistance
-    - switching gnd end of divider with PF4
-    - high resistor 100K/1M?
-        capacitor   10nF
-        http://www.eevblog.com/forum/beginners/measuring-battery-voltage-without-consuming-current/
- During USB suspend change clock source to internal RC from external Xtal(6.8)
- FRZCLK: you can freeze clock for power saving. still WAKEUPI and VBUSTI interrupts are available while freezing.(21.7.3)
- Suspend: Clear Suspend Bit, Freeze clock, disable PLL, MCU sleep(21.13)
-
-Improving:
- BT LED; connecting, linked, sleeping, deep sleeping
- Battry LED; blink(using timer?)
- move rn42 to protocol directory when it becomes reusable stack
- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
- ADC resolution
-    AVR120
-    AVR32138
-
-Testing:
- Factroy reset doesn't work; need to **test again** 10K pull-up is too high?
- Lipo voltage ADC value is not stabilized
- DCDC converter: squeaky inducter; try other inductors
-
- Keymap layer bug: during space is pressed(mousekey) press Fn(HHKB) then release space before Fn, in result HHKB layer is locked(toggled) unintentionally.

-Done:
- low battery alert(solid light) 09/04

-To enable BT when USB powered it still needs to turn siwtch on, Lipo consumes quinscent current at 5V converter in vain.(Not good)

-MCU can controlled power of RN-42 without hardware switch.
-When USB powered and switch is on Lipo consumes quinscent current at 5V converter in vain.(Not good)

-Switch is needed to save Lipo when not used because decent power saving is not available now. If firmware can turn off BT module completely and make MCU deep sleep the switch will be not even needed.

-DONE:
- BT_INDICATOR LED turns on wrongly when touching line or pin.  -- pull-up enabled on PF6/GPIO2 08/30
- Lipo charger configuration: fast charge time:  USB charger spec? -- used 2kohm
- use LED of charger to alarm low battery. LED should be powered directly from Lipo? - cancel; powered from VUSB
- Use RTS in serial_uart.c to resolve missing chars from help message of RN-42 - done
- CTS/RTS lines are needed? just connect in loop back if no flow control is needed. - done
- add IO pin to charger status CHRG; LED control(low) and detect charge status(input HiZ) 07.24
- LINKED: add trace on PIO2 to PF6   07.24
- Lipo voltage ADC sensing
- Lipo charger MCP73831: needs capacitor 4.7uF *2
- USB connection check - 07.01
- BT on/off check: whether RX line is pulled up? - checking RTS 07.01
- USB/BT switching  BT is on -> BT, BT is off -> USB - 07.01
- Under voltage lock out UVLO for protection of Lipo - Lipo has discharge protection at 3.100V    07.01
- Power saving: HHKB scan, BT radio control - 9h with 850mAh, this is enough   07.01
- Power selector doesn't work; Q4 MOSFET leaks from Lipo to USB power line. -- use Schottky instead 07/04
-

-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; keyobard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.

-Keyboard can be used with iPhone, but mouse cannot.
-To operate iOS with keyboard is not so useful, though.
-There may be iOS specific scancodes?

-
-Pairing
-------
-First, host initiates pairing process and once it is done, auto connect will work thereafter.
-SM,3        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.
-
-SR,Z        removes all remote addresses for reconnecting.
-                can be used to connect another host
-SR,I        registers last inquiry address
-
-
-Fast data mode
--------------
-The module enters fast data mode after 'remote configuration timer' window is passed from power on.
-In this mode the module does not accept '$$$' to enter command mode.
-
-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
-

-3.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.

+NerD keyboard firmware
+========================
+
+Korean Keyboard designed by GON.
+
+*Note that this is not the official firmware*
+
+
+Hardware revision
+-----------------
+
+This firmware was developed and tested for NerD pcb version 1.61 and 2.0.
+
+
+Supported features
+------------------
+
+* All layout options are supported
+* All leds are supported
+* 60% and 80% (TKL) pcbs are supported
+
+
+Changing Bootloader
+-------------------
+
+You can't simply just upload this firmware to a new NerD board because the original
+bootloader won't accept DFU connections.
+
+You can change the bootloader of the keyboard with an ISP programmer of your choice.
+The bootloader pins are easy to access on the NerD pcb.
+
+*Be aware that after changing the bootloader the official configuration software
+won't work anymore and you'll lose your warrenty. GON won't provide any support for this firmware.*
+
+
+Build
+-----
+
+For building you have to specify two build-options, LAYOUT and KEYMAP. The layout option defines
+pcb layout and can be either 60% or 80% at the momemnt. The keymap option selects your
+preferred keymapping.
+
+Move to this directory then just run `make LAYOUT=60 KEYMAP=ansi150`
+
+to compile a firmware for a 60% pcb with ANSI 150 key mapping.
