+### 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).

+### 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.
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:
```
You may need privilege to access the device on OS like Linux.
- try `sudo hid_listen`
-## Can't get message on console
+### 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).
- 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
+### Linux or UNIX like system requires Super User privilege
Just use 'sudo' to execute *hid_listen* with privilege.
```
$ sudo hid_listen
SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
```

+## Software Issues
-# Miscellaneous
-## NKRO Doesn't work
+### 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.

-## 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
+### 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`.

Properly configure bootloader size in **Makefile**. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.

-## Special Extra key doesn't work(System, Audio control keys)
+### 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
```

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.
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?
+### 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.
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.

+### 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
-## FLIP doesn't work
-### AtLibUsbDfu.dll not found
-Remove current driver and reinstall one FLIP provides from DeviceManager.

+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.
