# Frequently Asked Questions
-## General
-
-### What is QMK?
-
-[QMK](https://github.com/qmk), short for Quantum Mechanical Keyboard, is a group of people building tools for custom keyboards. We started with the [QMK firmware](https://github.com/qmk/qmk_firmware), a heavily modified fork of [TMK](https://github.com/tmk/tmk_keyboard).
-
-### Why the name Quantum?
-
-<!-- FIXME -->
-
-### What Differences Are There Between QMK and TMK?
-
-TMK was originally designed and implemented by [Jun Wako](https://github.com/tmk). QMK started as [Jack Humbert's](https://github.com/jackhumbert) fork of TMK for the Planck. After a while Jack's fork had diverged quite a bit from TMK, and in 2015 Jack decided to rename his fork to QMK.
-
-From a technical standpoint QMK builds upon TMK by adding several new features. Most notably QMK has expanded the number of available keycodes and uses these to implement advanced features like `S()`, `LCTL()`, and `MO()`. You can see a complete list of these keycodes in [Quantum Keycodes](quantum_keycodes.html).
-
-From a project and community management standpoint TMK maintains all the officially supported keyboards by himself, with a bit of community support. Separate community maintained forks exist or can be created for other keyboards. Only a few keymaps are provided by default, so users typically don't share keymaps with each other. QMK encourages sharing of both keyboards and keymaps through a centrally managed repository, accepting all pull requests that follows the quality standards. These are mostly community maintained, but the QMK team also helps when necessary.
-
-Both approaches have their merits and their drawbacks, and code flows freely between TMK and QMK when it makes sense.
-
-# Building
-
-## Windows
-
-### I'm on Windows Vista, 7, or 8, how do I setup my build environment?
-
-Follow the build instructions to [install MHV AVR Tools](https://docs.qmk.fm/build_environment_setup.html#windows-vista-and-later).
-
-### I'm on Windows 10 without the Creators Update. Do I have to install it?
-
-No, but if you don't install the creators update you will not be able to build and flash with a single command. You will be able to build but to flash you will have to use a separate program, such as [QMK Flasher](https://github.com/qmk/qmk_flasher).
-
-# Troubleshooting
-
-## 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:
-```
-
-If you can't get this 'Listening:' message try building 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"
-```
-
-## Software Issues
-
-### 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.
-
-https://github.com/tmk/tmk_keyboard#boot-magic-configuration---virtual-dip-switch
-
-### 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`.

-
-
-### 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.
-```
-byte Atmel/LUFA(ATMega32u4) byte Atmel(AT90SUB1286)
-0x0000 +---------------+ 0x00000 +---------------+

-
-
-### Special Extra key doesn't work(System, Audio control keys)
-You need to define `EXTRAKEY_ENABLE` in `rules.mk` to use them in QMK.
-
-```
-EXTRAKEY_ENABLE = yes # Audio control and System control
-```
-
-### 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.
-
-## Hardware Issues
-
-### 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.

-
-### 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.
-
-
-### 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.

-
-### 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.

-
-## Flashing Problems
-
-### Can't use dfu-programmer or QMK Flasher to flash on Windows
-
-Windows requires a driver to support the keyboard in DFU mode. You can use [QMK Driver Installer](https://github.com/qmk/qmk_driver_installer/releases) to install the necessary drivers.
