-## READ FIRST
-- **README** of top directory : https://github.com/tmk/tmk_keyboard/blob/master/README.md
-- **README** of target project(keyboard/converter) directory.

-Note that you'll need to read **both**.

-# Debug Console
-## hid_listen can't recognize device
-When debug console of your device is not ready you will see like this:
-
-    Waiting for device:.........
-
-once the device is pluged in then *hid_listen* finds it you will get this message:
-
-    Waiting for new device:.........................
-    Listening:
-
-Check if you can't get this 'Listening:' message:
-- build with `CONSOLE_ENABLE=yes` in **Makefile**.
-
-You may need privilege to access the device on OS like Linux.
-- try `sudo hid_listen`
-
-## Can't get message on console
-Check:
-- *hid_listen* finds your device. See above.
-- Enable debug with pressing **Magic**+d. See [Magic Commands](https://github.com/tmk/tmk_keyboard#magic-commands).
-- set `debug_enable=true` usually in `matrix_init()` in **matrix.c**.
-- try using 'print' function instead of debug print. See **common/print.h**.
-- disconnect other devices with console function. See [Issue #97](https://github.com/tmk/tmk_keyboard/issues/97).
-
-## Linux or UNIX like system requires Super User privilege
-Just use 'sudo' to execute *hid_listen* with privilege.
-```
-$ sudo hid_listen
-```
-
-Or add an *udev rule* for TMK devices with placing a file in rules directory. The directory may vary on each system.
-
-File: /etc/udev/rules.d/52-tmk-keyboard.rules(in case of Ubuntu)
-```
-# tmk keyboard products     https://github.com/tmk/tmk_keyboard
-SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
-```

-# Miscellaneous
-## NKRO Doesn't work
-First you have to compile frimware with this build option `NKRO_ENABLE` in **Makefile**.
-
-Try `Magic` **N** command(`LShift+RShift+N` by default) when **NKRO** still doesn't work. You can use this command to toggle between **NKRO** and **6KRO** mode temporarily. In some situations **NKRO** doesn't work you need to switch to **6KRO** mode, in particular when you are in BIOS.
-
-If your firmeare built with `BOOTMAGIC_ENABLE` you need to turn its switch on by `BootMagic` **N** command(`Space+N` by default). This setting is stored in EEPROM and keeped over power cycles.

-
-
-## TrackPoint needs reset circuit(PS/2 mouse support)
-Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

-## Can't read column of matrix beyond 16 
-Use `1UL<<16` instead of `1<<16` in `read_cols()` in **matrix.h** when your columns goes beyond 16.
-
-In C `1` means one of **int** type which is **16bit** in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say `1<<16`. You have to use **unsigned long** type with `1UL`.

-## Pull-up Resistor
-In some case converters needed to have pull-up resistors to work correctly. Place the resistor between VCC and signal line in parallel.
-
-For example:
-```
-Keyboard       Conveter
-               ,------.
-5V------+------|VCC   |
-        |      |      |
-        R      |      |
-        |      |      |
-Signal--+------|PD0   |
-               |      |
-GND------------|GND   |
-               `------'
-R: 1K Ohm resistor
-```

-## Arduino Micro's pin naming is confusing
-Note that Arduino Micro PCB marking is different from real AVR port name. D0 of Arduino Micro is not PD0, PD0 is D3. Check schematic yourself.
-http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
-
-
-
-## Bootloader jump doesn't work
-Properly configure bootloader size in **Makefile**. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.
-```
-# Size of Bootloaders in bytes:
-#   Atmel DFU loader(ATmega32U4)   4096    
-#   Atmel DFU loader(AT90USB128)   8192    
-#   LUFA bootloader(ATmega32U4)    4096             
-#   Arduino Caterina(ATmega32U4)   4096             
-#   USBaspLoader(ATmega***)        2048             
-#   Teensy   halfKay(ATmega32U4)   512              
-#   Teensy++ halfKay(AT90USB128)   2048
-OPT_DEFS += -DBOOTLOADER_SIZE=4096
-```
-AVR Boot section size are defined by setting **BOOTSZ** fuse in fact. Consult with your MCU datasheet.
-Note that **Word**(2 bytes) size and address are used in datasheet while TMK uses **Byte**.
-
-AVR Boot section is located at end of Flash memory like the followings.
-```

-## Special Extra key doesn't work(System, Audio control keys)
-You need to define `EXTRAKEY_ENABLE` in **makefile** to use them in TMK.
-```
-EXTRAKEY_ENABLE = yes          # Audio control and System control
-```
-http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-60.html#p157919
-
-
-## Wakeup from sleep doesn't work
-In Windows check `Allow this device to wake the computer` setting in Power **Management property** tab of **Device Manager**. Also check BIOS setting.
-
-Pressing any key during sleep should wake host.
-
-
-## Using Arduino?
-**Note that Arduino pin naming is different from actual chip.** For example, Arduino pin `D0` is not `PD0`. Check circuit with its schematics yourself.
-
-- http://arduino.cc/en/uploads/Main/arduino-leonardo-schematic_3b.pdf
-- http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
-
-Arduino leonardo and micro have **ATMega32U4** and can be used for TMK, though Arduino bootloader may be a problem.
-
-
-## Using PF4-7 pins of USB AVR?
-You need to set JTD bit of MCUCR yourself to use PF4-7 as GPIO. Those pins are configured to serve JTAG function by default. MCUs like ATMega*U* or AT90USB* are affeteced with this.
-
-If you are using Teensy this isn't needed. Teensy is shipped with JTAGEN fuse bit unprogrammed to disable the function.
-
-See this code.
-```
-    // JTAG disable for PORT F. write JTD bit twice within four cycles.
-    MCUCR |= (1<<JTD);
-    MCUCR |= (1<<JTD);
-```
-https://github.com/tmk/tmk_keyboard/blob/master/keyboard/hbkb/matrix.c#L67
-
-And read **26.5.1 MCU Control Register – MCUCR** of ATMega32U4 datasheet.
-
-
-## Adding LED indicators of Lock keys
-You need your own LED indicators for CapsLock, ScrollLock and NumLock? See this post.
-
-http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-120.html#p191560
-
-## Program Arduino Micro/Leonardo
-Push reset button and then run command like this within 8 seconds.
-
-```
-avrdude -patmega32u4 -cavr109 -b57600 -Uflash:w:adb_usb.hex -P/dev/ttyACM0
-```
-
-Device name will vary depending on your system.

-## USB 3 compatibility
-I heard some people have a problem with USB 3 port, try USB 2 port.
-
-
-## Mac compatibility
-### OS X 10.11 and Hub

-
-## Problem on BIOS(UEFI)/Resume(Sleep&Wake)/Power cycles
-Some people reported their keyboard stops working on BIOS and/or after resume(power cycles).
-
-As of now root of its cause is not clear but some build options seem to be related. In Makefile try to disable those options like `CONSOLE_ENABLE`, `NKRO_ENABLE`, `SLEEP_LED_ENABLE` and/or others.
