# Command Command, formerly known as Magic, is a way to change your keyboard's behavior without having to flash or unplug it to use [Bootmagic](feature_bootmagic.md). There is a lot of overlap between this functionality and the [Bootmagic Keycodes](feature_bootmagic.md#keycodes). Wherever possible we encourage you to use that feature instead of Command. On some keyboards Command is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk`: ```make COMMAND_ENABLE = yes ``` ## Usage To use Command, hold down the key combination defined by the `IS_COMMAND()` macro. By default this is Left Shift+Right Shift. Then, press the key corresponding to the command you want. For example, to output the current QMK version to the QMK Toolbox console, press Left Shift+Right Shift+`V`. ## Configuration If you would like to change the key assignments for Command, `#define` these in your `config.h` at either the keyboard or keymap level. All keycode assignments here must omit the `KC_` prefix. |Define |Default |Description | |------------------------------------|--------------------------------|------------------------------------------------| |`IS_COMMAND()` |`(get_mods() == MOD_MASK_SHIFT)`|The key combination to activate Command | |`MAGIC_KEY_SWITCH_LAYER_WITH_FKEYS` |`true` |Set default layer with the Function row | |`MAGIC_KEY_SWITCH_LAYER_WITH_NKEYS` |`true` |Set default layer with the number keys | |`MAGIC_KEY_SWITCH_LAYER_WITH_CUSTOM`|`false` |Set default layer with `MAGIC_KEY_LAYER0..9` | |`MAGIC_KEY_DEBUG` |`D` |Toggle debugging over serial | |`MAGIC_KEY_DEBUG_MATRIX` |`X` |Toggle key matrix debugging | |`MAGIC_KEY_DEBUG_KBD` |`K` |Toggle keyboard debugging | |`MAGIC_KEY_DEBUG_MOUSE` |`M` |Toggle mouse debugging | |`MAGIC_KEY_CONSOLE` |`C` |Enable the Command console | |`MAGIC_KEY_VERSION` |`V` |Print the running QMK version to the console | |`MAGIC_KEY_STATUS` |`S` |Print the current keyboard status to the console| |`MAGIC_KEY_HELP` |`H` |Print Command help to the console | |`MAGIC_KEY_HELP_ALT` |`SLASH` |Print Command help to the console (alternate) | |`MAGIC_KEY_LAYER0` |`0` |Make layer 0 the default layer | |`MAGIC_KEY_LAYER0_ALT` |`GRAVE` |Make layer 0 the default layer (alternate) | |`MAGIC_KEY_LAYER1` |`1` |Make layer 1 the default layer | |`MAGIC_KEY_LAYER2` |`2` |Make layer 2 the default layer | |`MAGIC_KEY_LAYER3` |`3` |Make layer 3 the default layer | |`MAGIC_KEY_LAYER4` |`4` |Make layer 4 the default layer | |`MAGIC_KEY_LAYER5` |`5` |Make layer 5 the default layer | |`MAGIC_KEY_LAYER6` |`6` |Make layer 6 the default layer | |`MAGIC_KEY_LAYER7` |`7` |Make layer 7 the default layer | |`MAGIC_KEY_LAYER8` |`8` |Make layer 8 the default layer | |`MAGIC_KEY_LAYER9` |`9` |Make layer 9 the default layer | |`MAGIC_KEY_BOOTLOADER` |`B` |Jump to bootloader | |`MAGIC_KEY_BOOTLOADER_ALT` |`ESC` |Jump to bootloader (alternate) | |`MAGIC_KEY_LOCK` |`CAPS` |Lock the keyboard so nothing can be typed | |`MAGIC_KEY_EEPROM` |`E` |Print stored EEPROM config to the console | |`MAGIC_KEY_EEPROM_CLEAR` |`BSPACE` |Clear the EEPROM | |`MAGIC_KEY_NKRO` |`N` |Toggle N-Key Rollover (NKRO) | |`MAGIC_KEY_SLEEP_LED` |`Z` |Toggle LED when computer is sleeping | /a> 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385
# RGB Lighting

QMK has the ability to control RGB LEDs attached to your keyboard. This is commonly called *underglow*, due to the LEDs often being mounted on the bottom of the keyboard, producing a nice diffused effect when combined with a translucent case.

![Planck with RGB Underglow](https://raw.githubusercontent.com/qmk/qmk_firmware/3774a7fcdab5544fc787f4c200be05fcd417e31f/keyboards/planck/keymaps/yang/planck-with-rgb-underglow.jpg)

Some keyboards come with RGB LEDs preinstalled. Others must have them installed after the fact. See the [Hardware Modification](#hardware-modification) section for information on adding RGB lighting to your keyboard.

Currently QMK supports the following addressable LEDs (however, the white LED in RGBW variants is not supported):

 * WS2811, WS2812, WS2812B, WS2812C, etc.
 * SK6812, SK6812MINI, SK6805

These LEDs are called "addressable" because instead of using a wire per color, each LED contains a small microchip that understands a special protocol sent over a single wire. The chip passes on the remaining data to the next LED, allowing them to be chained together. In this way, you can easily control the color of the individual LEDs.

## Usage

On keyboards with onboard RGB LEDs, it is usually enabled by default. If it is not working for you, check that your `rules.mk` includes the following:

```make
RGBLIGHT_ENABLE = yes
```

At minimum you must define the data pin your LED strip is connected to, and the number of LEDs in the strip, in your `config.h`. If your keyboard has onboard RGB LEDs, and you are simply creating a keymap, you usually won't need to modify these.

|Define         |Description                                                                                              |
|---------------|---------------------------------------------------------------------------------------------------------|
|`RGB_DI_PIN`   |The pin connected to the data pin of the LEDs                                                            |
|`RGBLED_NUM`   |The number of LEDs connected                                                                             |
|`RGBLED_SPLIT` |(Optional) For split keyboards, the number of LEDs connected on each half directly wired to `RGB_DI_PIN` |

Then you should be able to use the keycodes below to change the RGB lighting to your liking.

### Color Selection

QMK uses [Hue, Saturation, and Value](https://en.wikipedia.org/wiki/HSL_and_HSV) to select colors rather than RGB. The color wheel below demonstrates how this works.

<img src="gitbook/images/color-wheel.svg" alt="HSV Color Wheel" width="250"/>

Changing the **Hue** cycles around the circle.<br>
Changing the **Saturation** moves between the inner and outer sections of the wheel, affecting the intensity of the color.<br>
Changing the **Value** sets the overall brightness.<br>

if `RGBLIGHT_EFFECT_xxxx` or `RGBLIGHT_ANIMATIONS` is defined, you also have a number of animation modes at your disposal:

|Mode number symbol           |Additional number  |Description                            |
|-----------------------------|-------------------|---------------------------------------|

Check out [this video](https://youtube.com/watch?v=VKrpPAHlisY) for a demonstration.

Note: For versions older than 0.6.117, The mode numbers were written directly. In `quantum/rgblight.h` there is a contrast table between the old mode number and the current symbol.

### Effect and Animation Toggles

Use these defines to add or remove animations from the firmware. When you are running low on flash space, it can be helpful to disable animations you are not using.

|Define                              |Default      |Description                                                                          |

|`RGBLIGHT_EFFECT_SNAKE`             |*Not defined*|Enable snake animation mode.                                             |
|`RGBLIGHT_EFFECT_STATIC_GRADIENT`   |*Not defined*|Enable static gradient mode.                                             |

### Effect and Animation Settings

The following options are used to tweak the various animations:

|Define                              |Default      |Description                                                                          |
|------------------------------------|-------------|-------------------------------------------------------------------------------------|
|`RGBLIGHT_EFFECT_BREATHE_CENTER`    |*Not defined*|If defined, used to calculate the curve for the breathing animation. Valid values are 1.0 to 2.7 |
|`RGBLIGHT_EFFECT_BREATHE_MAX`       |`255`        |The maximum brightness for the breathing mode. Valid values are 1 to 255             |
|`RGBLIGHT_EFFECT_CHRISTMAS_INTERVAL`|`1000`       |How long to wait between light changes for the "Christmas" animation, in milliseconds|
|`RGBLIGHT_EFFECT_CHRISTMAS_STEP`    |`2`          |The number of LEDs to group the red/green colors by for the "Christmas" animation    |
|`RGBLIGHT_EFFECT_KNIGHT_LED_NUM`    |`RGBLED_NUM` |The number of LEDs to have the "Knight" animation travel                             |
|`RGBLIGHT_EFFECT_KNIGHT_LENGTH`     |`3`          |The number of LEDs to light up for the "Knight" animation                            |
|`RGBLIGHT_EFFECT_KNIGHT_OFFSET`     |`0`          |The number of LEDs to start the "Knight" animation from the start of the strip by    |
|`RGBLIGHT_RAINBOW_SWIRL_RANGE`      |`255`        |Range adjustment for the rainbow swirl effect to get different swirls                |
|`RGBLIGHT_EFFECT_SNAKE_LENGTH`      |`4`          |The number of LEDs to light up for the "Snake" animation                             |

### Example Usage to Reduce Memory Footprint
  1. Remove `RGBLIGHT_ANIMATIONS` from `config.h`.
  1. Selectively add the animations you want to enable. The following would enable two animations and save about 4KiB:

```diff
 #undef RGBLED_NUM
-#define RGBLIGHT_ANIMATIONS
+#define RGBLIGHT_EFFECT_STATIC_GRADIENT
+#define RGBLIGHT_EFFECT_RAINBOW_SWIRL
 #define RGBLED_NUM 12
 #define RGBLIGHT_HUE_STEP 8
 #define RGBLIGHT_SAT_STEP 8
```

### Animation Speed

You can also modify the speeds that the different modes animate at:

Here is a quick demo on Youtube (with NPKC KC60) (https://www.youtube.com/watch?v=VKrpPAHlisY).

```c
// How long (in milliseconds) to wait between animation steps for each of the "Solid color breathing" animations
const uint8_t RGBLED_BREATHING_INTERVALS[] PROGMEM = {30, 20, 10, 5};

// How long (in milliseconds) to wait between animation steps for each of the "Cycling rainbow" animations
const uint8_t RGBLED_RAINBOW_MOOD_INTERVALS[] PROGMEM = {120, 60, 30};

// How long (in milliseconds) to wait between animation steps for each of the "Swirling rainbow" animations
const uint8_t RGBLED_RAINBOW_SWIRL_INTERVALS[] PROGMEM = {100, 50, 20};

// How long (in milliseconds) to wait between animation steps for each of the "Snake" animations
const uint8_t RGBLED_SNAKE_INTERVALS[] PROGMEM = {100, 50, 20};

// How long (in milliseconds) to wait between animation steps for each of the "Knight" animations
const uint8_t RGBLED_KNIGHT_INTERVALS[] PROGMEM = {127, 63, 31};

// These control which hues are selected for each of the "Static gradient" modes
const uint8_t RGBLED_GRADIENT_RANGES[] PROGMEM = {255, 170, 127, 85, 64};
```

## Functions

If you need to change your RGB lighting in code, for example in a macro to change the color whenever you switch layers, QMK provides a set of functions to assist you. See [`rgblight.h`](https://github.com/qmk/qmk_firmware/blob/master/quantum/rgblight.h) for the full list, but the most commonly used functions include:

### Utility Functions

These are defined in [`rgblight_list.h`](https://github.com/qmk/qmk_firmware/blob/master/quantum/rgblight_list.h). Feel free to add to this list!


## Changing the order of the LEDs

If you want to make the logical order of LEDs different from the electrical connection order, you can do this by defining the `RGBLIGHT_LED_MAP` macro in your `config.h`.

Normally, the contents of the LED buffer are output to the LEDs in the same order.

By defining `RGBLIGHT_LED_MAP` as in the example below, you can specify the LED with addressing in reverse order of the electrical connection order.

```c
// config.h

#define RGBLED_NUM 4
#define RGBLIGHT_LED_MAP { 3, 2, 1, 0 }

```
<img src="https://user-images.githubusercontent.com/2170248/55743725-08ad7a80-5a6e-11e9-83ed-126a2b0209fc.JPG" alt="simple mapped" width="50%"/>

For keyboards that use the RGB LEDs as a backlight for each key, you can also define it as in the example below.

```c
// config.h

#define RGBLED_NUM 30

/* RGB LED Conversion macro from physical array to electric array */
#define LED_LAYOUT( \
    L00, L01, L02, L03, L04, L05,  \
    L10, L11, L12, L13, L14, L15,  \
    L20, L21, L22, L23, L24, L25,  \
    L30, L31, L32, L33, L34, L35,  \
    L40, L41, L42, L43, L44, L45 ) \
  { \
    L05, L04, L03, L02, L01, L00,   \
    L10, L11, L12, L13, L14, L15,   \
    L25, L24, L23, L22, L21, L20,   \
    L30, L31, L32, L33, L34, L35,   \
    L46, L45, L44, L43, L42, L41    \
  }

/* RGB LED logical order map */
/* Top->Bottom, Right->Left */
#define RGBLIGHT_LED_MAP LED_LAYOUT( \
  25, 20, 15, 10,  5,  0,       \
  26, 21, 16, 11,  6,  1,       \
  27, 22, 17, 12,  7,  2,       \
  28, 23, 18, 13,  8,  3,       \
  29, 24, 19, 14,  9,  4 )

```
## Clipping Range

Using the `rgblight_set_clipping_range()` function, you can prepare more buffers than the actual number of LEDs, and output some of the buffers to the LEDs. This is useful if you want the split keyboard to treat left and right LEDs as logically contiguous.

You can set the Clipping Range by executing the following code.

```c
// some source
rgblight_set_clipping_range(3, 4);
```
<img src="https://user-images.githubusercontent.com/2170248/55743785-2bd82a00-5a6e-11e9-9d4b-1b4ffaf4932b.JPG" alt="clip direct" width="70%"/>

In addition to setting the Clipping Range, you can use `RGBLIGHT_LED_MAP` together.

```c
// config.h
#define RGBLED_NUM 8
#define RGBLIGHT_LED_MAP { 7, 6, 5, 4, 3, 2, 1, 0 }

// some soruce
  rgblight_set_clipping_range(3, 4);
```
<img src="https://user-images.githubusercontent.com/2170248/55743747-119e4c00-5a6e-11e9-91e5-013203ffae8a.JPG" alt="clip mapped" width="70%"/>

## Hardware Modification

If your keyboard lacks onboard underglow LEDs, you may often be able to solder on an RGB LED strip yourself. You will need to find an unused pin to wire to the data pin of your LED strip. Some keyboards may break out unused pins from the MCU to make soldering easier. The other two pins, VCC and GND, must also be connected to the appropriate power pins.
