See [doc/other_projects.md](doc/other_projects.md). +# Quantum Mechanical Keyboard Firmware + +This is a keyboard firmware based on the [tmk_keyboard firmware](http://github.com/tmk/tmk_keyboard) with some useful features for Atmel AVR controllers, and more specifically, the [OLKB product line](http://olkb.co), the [ErgoDox EZ](http://www.ergodox-ez.com) keyboard, and the [Clueboard product line](http://clueboard.co/). + +QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, TMK. + +This documentation is edited and maintained by Erez Zukerman of ErgoDox EZ. If you spot any typos or inaccuracies, please [open an issue](https://github.com/jackhumbert/qmk_firmware/issues/new). + +The OLKB product firmwares are maintained by Jack, the Ergodox EZ by Erez, and the Clueboard by [Zach White](https://github.com/skullydazed). + +## Important background info: TMK documentation + +The documentation below explains QMK customizations and elaborates on some of the more useful features of TMK. To understand the base firmware, and especially what *layers* are and how they work, please see [TMK_README.md](/TMK_README.md). + +## Getting started + +* [BUILD_GUIDE.md](BUILD_GUIDE.md) contains instructions to set up a build environment, build the firmware, and deploy it to a keyboard. Once your build environment has been set up, all `make` commands to actually build the firmware must be run from a folder in `keyboard/`. +* If you're looking to customize a keyboard that currently runs QMK or TMK, find your keyboard's directory under `keyboard/` and run the make commands from there. +* If you're looking to apply this firmware to an entirely new hardware project (a new kind of keyboard), you can create your own Quantum-based project by using `./new_project.sh `, which will create `/keyboard/` with all the necessary components for a Quantum project. + +### Makefile Options + +You have access to a bunch of goodies! Check out the Makefile to enable/disable some of the features. Uncomment the `#` to enable them. Setting them to `no` does nothing and will only confuse future you. + + BACKLIGHT_ENABLE = yes # Enable keyboard backlight functionality + MIDI_ENABLE = yes # MIDI controls + UNICODE_ENABLE = no # <-- This is how you disable an option, just set it to "no" + BLUETOOTH_ENABLE = yes # Enable Bluetooth with the Adafruit EZ-Key HID + +### Customizing Makefile options on a per-keymap basis + +If your keymap directory has a file called `makefile.mk` (note the lowercase filename, and the `.mk` extension), any Makefile options you set in that file will take precedence over other Makefile options (those set for Quantum as a whole or for your particular keyboard). + +So let's say your keyboard's makefile has `CONSOLE_ENABLE = yes` (or maybe doesn't even list the `CONSOLE_ENABLE` option, which would cause it to revert to the global Quantum default). You want your particular keymap to not have the debug console, so you make a file called `makefile.mk` and specify `CONSOLE_ENABLE = no`. + +## Quick aliases to common actions + +Your keymap can include shortcuts to common operations (called "function actions" in tmk). + +### Switching and toggling layers + +`MO(layer)` - momentary switch to *layer*. As soon as you let go of the key, the layer is deactivated and you pop back out to the previous layer. When you apply this to a key, that same key must be set as `KC_TRNS` on the destination layer. Otherwise, you won't make it back to the original layer when you release the key (and you'll get a keycode sent). You can only switch to layers *above* your current layer. If you're on layer 0 and you use `MO(1)`, that will switch to layer 1 just fine. But if you include `MO(3)` on layer 5, that won't do anything for you -- because layer 3 is lower than layer 5 on the stack. + +`LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped. Like `MO()`, this only works upwards in the layer stack (`layer` must be higher than the current layer). + +`TG(layer)` - toggles a layer on or off. As with `MO()`, you should set this key as `KC_TRNS` in the destination layer so that tapping it again actually toggles back to the original layer. Only works upwards in the layer stack. + +### Fun with modifier keys + +* `LSFT(kc)` - applies left Shift to *kc* (keycode) - `S(kc)` is an alias +* `RSFT(kc)` - applies right Shift to *kc* +* `LCTL(kc)` - applies left Control to *kc* +* `RCTL(kc)` - applies right Control to *kc* +* `LALT(kc)` - applies left Alt to *kc* +* `RALT(kc)` - applies right Alt to *kc* +* `LGUI(kc)` - applies left GUI (command/win) to *kc* +* `RGUI(kc)` - applies right GUI (command/win) to *kc* +* `HYPR(kc)` - applies Hyper (all modifiers) to *kc* +* `MEH(kc)` - applies Meh (all modifiers except Win/Cmd) to *kc* +* `LCAG(kc)` - applies CtrlAltGui to *kc* + +You can also chain these, like this: + + LALT(LCTL(KC_DEL)) -- this makes a key that sends Alt, Control, and Delete in a single keypress. + +The following shortcuts automatically add `LSFT()` to keycodes to get commonly used symbols. Their long names are also available and documented in `/quantum/keymap_common.h`. + + KC_TILD ~ + KC_EXLM ! + KC_AT @ + KC_HASH # + KC_DLR $ + KC_PERC % + KC_CIRC ^ + KC_AMPR & + KC_ASTR * + KC_LPRN ( + KC_RPRN ) + KC_UNDS _ + KC_PLUS + + KC_LCBR { + KC_RCBR } + KC_PIPE | + KC_COLN : + +`MT(mod, kc)` - is *mod* (modifier key - MOD_LCTL, MOD_LSFT) when held, and *kc* when tapped. In other words, you can have a key that sends Esc (or the letter O or whatever) when you tap it, but works as a Control key or a Shift key when you hold it down. + +These are the values you can use for the `mod` in `MT()` (right-hand modifiers are not available): + + * MOD_LCTL + * MOD_LSFT + * MOD_LALT + * MOD_LGUI + +These can also be combined like `MOD_LCTL | MOD_LSFT` e.g. `MT(MOD_LCTL | MOD_LSFT, KC_ESC)` which would activate Control and Shift when held, and send Escape when tapped. + +We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact: + + * `CTL_T(kc)` - is LCTL when held and *kc* when tapped + * `SFT_T(kc)` - is LSFT when held and *kc* when tapped + * `ALT_T(kc)` - is LALT when held and *kc* when tapped + * `GUI_T(kc)` - is LGUI when held and *kc* when tapped + * `ALL_T(kc)` - is Hyper (all mods) when held and *kc* when tapped. To read more about what you can do with a Hyper key, see [this blog post by Brett Terpstra](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/) + * `LCAG_T(kc)` - is CtrlAltGui when held and *kc* when tapped + * `MEH_T(kc)` - is like Hyper, but not as cool -- does not include the Cmd/Win key, so just sends Alt+Ctrl+Shift. + +### Temporarily setting the default layer + +`DF(layer)` - sets default layer to *layer*. The default layer is the one at the "bottom" of the layer stack - the ultimate fallback layer. This currently does not persist over power loss. When you plug the keyboard back in, layer 0 will always be the default. It is theoretically possible to work around that, but that's not what `DF` does. + +### Prevent stuck modifiers + +Consider the following scenario: + +1. Layer 0 has a key defined as Shift. +2. The same key is defined on layer 1 as the letter A. +3. User presses Shift. +4. User switches to layer 1 for whatever reason. +5. User releases Shift, or rather the letter A. +6. User switches back to layer 0. + +Shift was actually never released and is still considered pressed. + +If such situation bothers you add this to your `config.h`: + + #define PREVENT_STUCK_MODIFIERS + +This option uses 5 bytes of memory per every 8 keys on the keyboard +rounded up (5 bits per key). For example on Planck (48 keys) it uses +(48/8)\*5 = 30 bytes. + +### Remember: These are just aliases + +These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the tmk ACTION_* functions, please see the [TMK documentation](https://github.com/jackhumbert/qmk_firmware/blob/master/tmk_core/doc/keymap.md#2-action). + +Instead of using `FNx` when defining `ACTION_*` functions, you can use `F(x)` - the benefit here is being able to use more than 32 function actions (up to 4096), if you happen to need them. + +## Macro shortcuts: Send a whole string when pressing just one key + +Instead of using the `ACTION_MACRO` function, you can simply use `M(n)` to access macro *n* - *n* will get passed into the `action_get_macro` as the `id`, and you can use a switch statement to trigger it. This gets called on the keydown and keyup, so you'll need to use an if statement testing `record->event.pressed` (see keymap_default.c). + +```c +const macro_t *action_get_macro(keyrecord_t *record, uint8_t id, uint8_t opt) // this is the function signature -- just copy/paste it into your keymap file as it is. +{ + switch(id) { + case 0: // this would trigger when you hit a key mapped as M(0) + if (record->event.pressed) { + return MACRO( I(255), T(H), T(E), T(L), T(L), W(255), T(O), END ); // this sends the string 'hello' when the macro executes + } + break; + } + return MACRO_NONE; +}; +``` +A macro can include the following commands: + +* I() change interval of stroke in milliseconds. +* D() press key. +* U() release key. +* T() type key(press and release). +* W() wait (milliseconds). +* END end mark. + +So above you can see the stroke interval changed to 255ms between each keystroke, then a bunch of keys being typed, waits a while, then the macro ends. + +Note: Using macros to have your keyboard send passwords for you is possible, but a bad idea. + +### Advanced macro functions + +To get more control over the keys/actions your keyboard takes, the following functions are available to you in the `action_get_macro` function block: + +* `record->event.pressed` + +This is a boolean value that can be tested to see if the switch is being pressed or released. An example of this is + +```c +if (record->event.pressed) { + // on keydown +} else { + // on keyup +} +``` + +* `register_code();` + +This sends the `` keydown event to the computer. Some examples would be `KC_ESC`, `KC_C`, `KC_4`, and even modifiers such as `KC_LSFT` and `KC_LGUI`. + +* `unregister_code();` + +Parallel to `register_code` function, this sends the `` keyup event to the computer. If you don't use this, the key will be held down until it's sent. + +* `layer_on();` + +This will turn on the layer `` - the higher layer number will always take priority. Make sure you have `KC_TRNS` for the key you're pressing on the layer you're switching to, or you'll get stick there unless you have another plan. + +* `layer_off();` + +This will turn off the layer ``. + +* `clear_keyboard();` + +This will clear all mods and keys currently pressed. + +* `clear_mods();` + +This will clear all mods currently pressed. + +* `clear_keyboard_but_mods();` + +This will clear all keys besides the mods currently pressed. + +* `update_tri_layer(layer_1, layer_2, layer_3);` + +If the user attempts to activate layer 1 AND layer 2 at the same time (for example, by hitting their respective layer keys), layer 3 will be activated. Layers 1 and 2 will _also_ be activated, for the purposes of fallbacks (so a given key will fall back from 3 to 2, to 1 -- and only then to 0). + +#### Naming your macros + +If you have a bunch of macros you want to refer to from your keymap, while keeping the keymap easily readable, you can just name them like so: + +``` +#define AUD_OFF M(6) +#define AUD_ON M(7) +#define MUS_OFF M(8) +#define MUS_ON M(9) +#define VC_IN M(10) +#define VC_DE M(11) +#define PLOVER M(12) +#define EXT_PLV M(13) +``` + +As was done on the [Planck default keymap](/keyboard/planck/keymaps/default/keymap.c#L33-L40) + +#### Timer functionality + +It's possible to start timers and read values for time-specific events - here's an example: + +```c +static uint16_t key_timer; +key_timer = timer_read(); +if (timer_elapsed(key_timer) < 100) { + // do something if less than 100ms have passed +} else { + // do something if 100ms or more have passed +} +``` + +It's best to declare the `static uint16_t key_timer;` outside of the macro block (top of file, etc). + +#### Example 1: Single-key copy/paste (hold to copy, tap to paste) + +With QMK, it's easy to make one key do two things, as long as one of those things is being a modifier. :) So if you want a key to act as Ctrl when held and send the letter R when tapped, that's easy: `CTL_T(KC_R)`. But what do you do when you want that key to send Ctrl-V (paste) when tapped, and Ctrl-C (copy) when held? + +Here's what you do: + + +``` +static uint16_t key_timer; + +const macro_t *action_get_macro(keyrecord_t *record, uint8_t id, uint8_t opt) +{ + switch(id) { + case 0: { + if (record->event.pressed) { + key_timer = timer_read(); // if the key is being pressed, we start the timer. + } + else { // this means the key was just released, so we can figure out how long it was pressed for (tap or "held down"). + if (timer_elapsed(key_timer) > 150) { // 150 being 150ms, the threshhold we pick for counting something as a tap. + return MACRO( D(LCTL), T(C), U(LCTL), END ); + } + else { + return MACRO( D(LCTL), T(V), U(LCTL), END ); + } + } + break; + } + } + return MACRO_NONE; +}; +``` + +And then, to assign this macro to a key on your keyboard layout, you just use `M(0)` on the key you want to press for copy/paste. + +#### Example 2: Space Cadet Shift (making it easy to send opening and closing parentheses) + +In the [Modern Space Cadet Keyboard](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/#shift-parentheses), one of cooler features is the Shift Parentheses. To quote Steve Losh: + + > When held while pressing other keys, act like Shift. + > When pressed and released on their own, type an opening or closing parenthesis (left and right shift respectively). + +``` +static uint16_t key_timer; + +const macro_t *action_get_macro(keyrecord_t *record, uint8_t id, uint8_t opt) +{ + switch(id) { + case 0: { + if (record->event.pressed) { + key_timer = timer_read(); // if the key is being pressed, we start the timer. + register_code(KC_LSFT); // we're now holding down Shift. + } else { // this means the key was just released, so we can figure out how long it was pressed for (tap or "held down"). + if (timer_elapsed(key_timer) < 150) { // 150 being 150ms, the threshhold we pick for counting something as a tap. + register_code(KC_9); // sending 9 while Shift is held down gives us an opening paren + unregister_code(KC_9); // now let's let go of that key + } + unregister_code(KC_LSFT); // let's release the Shift key now. + } + break; + } + case 1: { + if (record->event.pressed) { + key_timer = timer_read(); // Now we're doing the same thing, only for the right shift/close paren key + register_code(KC_RSFT); + } else { + if (timer_elapsed(key_timer) < 150) { + register_code(KC_0); + unregister_code(KC_0); + } + unregister_code(KC_RSFT); + } + break; + } + } + return MACRO_NONE; +}; +``` + +And then, to assign this macro to a key on your keyboard layout, you just use `M(0)` on the key you want to press for left shift/opening parens, and `M(1)` for right shift/closing parens. + +## Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc) + +Everything is assuming you're in Qwerty (in software) by default, but there is built-in support for using a Colemak or Dvorak layout by including this at the top of your keymap: + + #include + +If you use Dvorak, use `keymap_dvorak.h` instead of `keymap_colemak.h` for this line. After including this line, you will get access to: + + * `CM_*` for all of the Colemak-equivalent characters + * `DV_*` for all of the Dvorak-equivalent characters + +These implementations assume you're using Colemak or Dvorak on your OS, not on your keyboard - this is referred to as a software-implemented layout. If your computer is in Qwerty and your keymap is in Colemak or Dvorak, this is referred to as a firmware-implemented layout, and you won't need these features. + +To give an example, if you're using software-implemented Colemak, and want to get an `F`, you would use `CM_F` - `KC_F` under these same circumstances would result in `T`. + +## Additional language support + +In `quantum/keymap_extras/`, you'll see various language files - these work the same way as the alternative layout ones do. Most are defined by their two letter country/language code followed by an underscore and a 4-letter abbreviation of its name. `FR_UGRV` which will result in a `ù` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware (but it's being worked on - see Unicode support). + +## Unicode support + +You can currently send 4 hex digits with your OS-specific modifier key (RALT for OSX with the "Unicode Hex Input" layout) - this is currently limited to supporting one OS at a time, and requires a recompile for switching. 8 digit hex codes are being worked on. The keycode function is `UC(n)`, where *n* is a 4 digit hexidecimal. Enable from the Makefile. + +## Other firmware shortcut keycodes + +* `RESET` - puts the MCU in DFU mode for flashing new firmware (with `make dfu`) +* `DEBUG` - the firmware into debug mode - you'll need hid_listen to see things +* `BL_ON` - turns the backlight on +* `BL_OFF` - turns the backlight off +* `BL_` - sets the backlight to level *n* +* `BL_INC` - increments the backlight level by one +* `BL_DEC` - decrements the backlight level by one +* `BL_TOGG` - toggles the backlight +* `BL_STEP` - steps through the backlight levels + +Enable the backlight from the Makefile. + +## MIDI functionalty + +This is still a WIP, but check out `quantum/keymap_midi.c` to see what's happening. Enable from the Makefile. + +## Bluetooth functionality + +This requires [some hardware changes](https://www.reddit.com/r/MechanicalKeyboards/comments/3psx0q/the_planck_keyboard_with_bluetooth_guide_and/?ref=search_posts), but can be enabled via the Makefile. The firmware will still output characters via USB, so be aware of this when charging via a computer. It would make sense to have a switch on the Bluefruit to turn it off at will. + +## International Characters on Windows + +[AutoHotkey](https://autohotkey.com) allows Windows users to create custom hotkeys among others. + +The method does not require Unicode support in the keyboard itself but depends instead of AutoHotkey running in the background. + +First you need to select a modifier combination that is not in use by any of your programs. +CtrlAltWin is not used very widely and should therefore be perfect for this. +There is a macro defined for a mod-tab combo `LCAG_T`. +Add this mod-tab combo to a key on your keyboard, e.g.: `LCAG_T(KC_TAB)`. +This makes the key behave like a tab key if pressed and released immediately but changes it to the modifier if used with another key. + +In the default script of AutoHotkey you can define custom hotkeys. + + <^
