This will get you all set up. +* Read the [QUICK_START.md](QUICK_START.md) if you want to hit the ground running with minimal fuss or you aren't a technical person and you just want to build the firmware with the least amount of hassle possible. +* 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. +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 = yes # Unicode support - this is commented out, just as an example.

Some protocol files are under **Modified BSD License**. -LUFA, PJRC and V-USB stack have their own license respectively. +### 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). -Build Firmware and Program Controller -------------------------------------- -See [doc/build.md](doc/build.md). +`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* -Start Your Own Project ------------------------ -**TBD** -### Config.h Options -#### 1.

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 -Debugging --------- -Use PJRC's `hid_listen` to see debug messages.

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. -### Keyboard Protocols -* lufa/ - LUFA USB stack -* pjrc/ - PJRC USB stack -* vusb/ - Objective Development V-USB -* iwrap/ - Bluetooth HID for Bluegiga iWRAP -* ps2.c - PS/2 protocol -* adb.c - Apple Desktop Bus protocol -* m0110.c - Macintosh 128K/512K/Plus keyboard protocol -* news.c - Sony NEWS keyboard protocol -* x68k.c - Sharp X68000 keyboard protocol -* serial_soft.c - Asynchronous Serial protocol implemented by software - - - -Coding Style -------------- -- Doesn't use Tab to indent, use 4-spaces instead. +### 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. + +#### 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). + +## 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 amont 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. + + <^
