1 atreus keyboard firmware
6 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.
8 BACKLIGHT_ENABLE = yes # Enable keyboard backlight functionality
9 MIDI_ENABLE = yes # MIDI controls
10 # UNICODE_ENABLE = yes # Unicode support - this is commented out, just as an example. You have to use #, not //
11 BLUETOOTH_ENABLE = yes # Enable Bluetooth with the Adafruit EZ-Key HID
13 ## Atreus specific information
15 These configuration files are specifically for the Atreus keyboards created by Phil Hagelberg (@technomancy). This keyboard is available in two variants: one powered by a Teensy 2, one powered by an A-Star. This repository currently assumes that you have an A-Star powered Atreus. If you are using a Teensy2, specify that by adding `TEENSY2=yes` to your `make` commands.
17 If you are coming from the [atreus-firmware](https://github.com/technomancy/atreus-firmware), we've also brought forward the `make upload` command for you to use.
19 ## Quick aliases to common actions
21 Your keymap can include shortcuts to common operations (called "function actions" in tmk).
23 ### Switching and toggling layers
25 `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.
27 `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).
29 `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.
31 ### Fun with modifier keys
33 * `LSFT(kc)` - applies left Shift to *kc* (keycode) - `S(kc)` is an alias
34 * `RSFT(kc)` - applies right Shift to *kc*
35 * `LCTL(kc)` - applies left Control to *kc*
36 * `RCTL(kc)` - applies right Control to *kc*
37 * `LALT(kc)` - applies left Alt to *kc*
38 * `RALT(kc)` - applies right Alt to *kc*
39 * `LGUI(kc)` - applies left GUI (command/win) to *kc*
40 * `RGUI(kc)` - applies right GUI (command/win) to *kc*
42 You can also chain these, like this:
44 LALT(LCTL(KC_DEL)) -- this makes a key that sends Alt, Control, and Delete in a single keypress.
46 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`.
66 `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.
68 These are the values you can use for the `mod` in `MT()` (right-hand modifiers are not available):
75 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.
77 We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact:
79 * `CTL_T(kc)` - is LCTL when held and *kc* when tapped
80 * `SFT_T(kc)` - is LSFT when held and *kc* when tapped
81 * `ALT_T(kc)` - is LALT when held and *kc* when tapped
82 * `GUI_T(kc)` - is LGUI when held and *kc* when tapped
83 * `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/)
85 ### Temporarily setting the default layer
87 `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.
89 ### Remember: These are just aliases
91 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).
93 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.
95 ## Macro shortcuts: Send a whole string when pressing just one key
97 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).
100 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.
103 case 0: // this would trigger when you hit a key mapped as M(0)
104 if (record->event.pressed) {
105 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
112 A macro can include the following commands:
114 * I() change interval of stroke in milliseconds.
117 * T() type key(press and release).
118 * W() wait (milliseconds).
121 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.
123 Note: Using macros to have your keyboard send passwords for you is a bad idea.
125 ### Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc)
127 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:
129 #include "keymap_<layout>.h"
131 Where <layout> is "colemak" or "dvorak". After including this line, you will get access to:
133 * `CM_*` for all of the Colemak-equivalent characters
134 * `DV_*` for all of the Dvorak-equivalent characters
136 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.
138 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`.
140 ## Additional language support
142 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 `รน` 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).
146 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.
148 ## Other firmware shortcut keycodes
150 * `RESET` - puts the MCU in DFU mode for flashing new firmware (with `make dfu`)
151 * `DEBUG` - the firmware into debug mode - you'll need hid_listen to see things
152 * `BL_ON` - turns the backlight on
153 * `BL_OFF` - turns the backlight off
154 * `BL_<n>` - sets the backlight to level *n*
155 * `BL_INC` - increments the backlight level by one
156 * `BL_DEC` - decrements the backlight level by one
157 * `BL_TOGG` - toggles the backlight
158 * `BL_STEP` - steps through the backlight levels
160 Enable the backlight from the Makefile.
164 This is still a WIP, but check out `quantum/keymap_midi.c` to see what's happening. Enable from the Makefile.
166 ## Bluetooth functionality
168 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.
172 Download or clone the whole firmware and navigate to the keyboards/planck folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use `make dfu` to program your PCB once you hit the reset button.
174 Depending on which keymap you would like to use, you will have to compile slightly differently.
177 To build with the default keymap, simply run `make`.
180 Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `<name>.c` and see keymap document (you can find in top readme.md) and existent keymap files.
182 To build the firmware binary hex file with a keymap just do `make` with `KEYMAP` option like:
184 $ make KEYMAP=[default|jack|<name>]
186 Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
