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? - - - -### 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`. - -http://deskthority.net/workshop-f7/rebuilding-and-redesigning-a-classic-thinkpad-keyboard-t6181-60.html#p146279 - - -### 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 +---------------+ - | | | | - | | | | - | Application | | Application | - | | | | - = = = = - | | 32KB-4KB | | 128KB-8KB -0x6000 +---------------+ 0x1E000 +---------------+ - | Bootloader | 4KB | Bootloader | 8KB -0x7FFF +---------------+ 0x1FFFF +---------------+ - - -byte Teensy(ATMega32u4) byte Teensy++(AT90SUB1286) -0x0000 +---------------+ 0x00000 +---------------+ - | | | | - | | | | - | Application | | Application | - | | | | - = = = = - | | 32KB-512B | | 128KB-2KB -0x7E00 +---------------+ 0x1FC00 +---------------+ - | Bootloader | 512B | Bootloader | 2KB -0x7FFF +---------------+ 0x1FFFF +---------------+ -``` - -And see this discussion for further reference. -https://github.com/tmk/tmk_keyboard/issues/179 - - -### 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. - -- http://geekhack.org/index.php?topic=50176.msg1127447#msg1127447 -- http://www.mikrocontroller.net/attachment/52583/tpm754.pdf - -### 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<
