 # RGB Lighting
 
-If you've installed addressable RGB lights on your keyboard you can control them with QMK. Currently we support the following addressable LEDs on Atmel AVR processors:
+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.
 
-* WS2811 and variants (WS2812, WS2812B, WS2812C, etc)
-* SK6812RGBW

-Some keyboards come with RGB LEDs pre-installed. Others have to have LEDs installed after the fact. See below for information on modifying your keyboard.
+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.
 
-## Selecting Colors
+Currently QMK supports the following addressable LEDs on AVR microcontrollers (however, the white LED in RGBW variants is not supported):
 
-QMK uses Hue, Saturation, and Value to set color rather than using RGB. You can use the color wheel below to see how this works. Changing the Hue will cycle around the circle. Saturation will affect the intensity of the color, which you can see as you move from the inner part to the outer part of the wheel. Value sets the overall brightness.

+ * SK6812, SK6812MINI, SK6805
 
-<img src="gitbook/images/color-wheel.svg" alt="HSV Color Wheel" width="250">
+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.
 
-If you would like to learn more about HSV you can start with the [Wikipedia article](https://en.wikipedia.org/wiki/HSL_and_HSV).
+## Usage
 
-## Configuration
+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:
 
-Before RGB Lighting can be used you have to enable it in `rules.mk`:
+```make
+RGBLIGHT_ENABLE = yes
+```
 
-    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.
 
-You can configure the behavior of the RGB lighting by defining values inside `config.h`.
+|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` |
 
-### Required Configuration
+Then you should be able to use the keycodes below to change the RGB lighting to your liking.
 
-At minimum you have to define the pin your LED strip is connected to and the number of LEDs connected.
+### Color Selection
 
-```c
-#define RGB_DI_PIN D7     // The pin the LED strip is connected to
-#define RGBLED_NUM 14     // Number of LEDs in your strip
-```
+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"/>
 
-### Optional Configuration
+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>
 
-You can change the behavior of the RGB Lighting by setting these configuration values. Use `#define <Option> <Value>` in a `config.h` at the keyboard, revision, or keymap level.

+
+### 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
+```
 
-If you have `#define RGBLIGHT_ANIMATIONS` in your `config.h` you will have a number of animation modes you can cycle through using the `RGB_MOD` key. You can also `#define` other options to tweak certain animations.
+### Animation Speed
 
-| Option | Default Value | Description |
-|--------|---------------|-------------|
-| `RGBLIGHT_ANIMATIONS` | | `#define` this to enable animation modes. |
-| `RGBLIGHT_EFFECT_BREATHE_CENTER` | 1.85 | Used to calculate the curve for the breathing animation. Valid values 1.0-2.7. |
-| `RGBLIGHT_EFFECT_BREATHE_MAX` | 255 | The maximum brightness for the breathing mode. Valid values 1-255. |
-| `RGBLIGHT_EFFECT_SNAKE_LENGTH` | 4 | The number of LEDs to light up for the "snake" animation. |
-| `RGBLIGHT_EFFECT_KNIGHT_LENGTH` | 3 | The number of LEDs to light up for the "knight" animation. |
-| `RGBLIGHT_EFFECT_KNIGHT_OFFSET` | 0 | Start the knight animation this many LEDs from the start of the strip. |
-| `RGBLIGHT_EFFECT_KNIGHT_LED_NUM` | RGBLED_NUM | The number of LEDs to have the "knight" animation travel. |
-| `RGBLIGHT_EFFECT_CHRISTMAS_INTERVAL` | 1000 | How long to wait between light changes for the "christmas" animation. Specified in ms. |
-| `RGBLIGHT_EFFECT_CHRISTMAS_STEP` | 2 | How many LED's to group the red/green colors by for the christmas mode. |
+You can also modify the speeds that the different modes animate at:
 
-You can also tweak the behavior of the animations by defining these consts in your `keymap.c`. These mostly affect the speed 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 ms) to wait between animation steps for the breathing mode
+// 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 ms) to wait between animation steps for the rainbow mode
+// 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 ms) to wait between animation steps for the swirl mode
+// 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 ms) to wait between animation steps for the snake mode
+// 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 ms) to wait between animation steps for the knight modes
+// 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 colors are selected for the gradient mode
-const uint16_t RGBLED_GRADIENT_RANGES[] PROGMEM = {360, 240, 180, 120, 90};
+// 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};
 ```

-Look in `rgblights.h` for all available functions, but if you want to control all or some LEDs your goto functions are:
+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:

-## Hardware Modification
+## Changing the order of the LEDs
 
-![Planck with RGB Underglow](https://raw.githubusercontent.com/qmk/qmk_firmware/master/keyboards/planck/keymaps/yang/planck-with-rgb-underglow.jpg)
+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`.
 
-Here is a quick demo on Youtube (with NPKC KC60) (https://www.youtube.com/watch?v=VKrpPAHlisY).
+Normally, the contents of the LED buffer are output to the LEDs in the same order.
+<img src="https://user-images.githubusercontent.com/2170248/55743718-01866c80-5a6e-11e9-8134-25419928327a.JPG" alt="simple dicrect" width="50%"/>
 
-For this mod, you need an unused pin wiring to DI of WS2812 strip. After wiring the VCC, GND, and DI, you can enable the underglow in your Makefile.
+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.
 
-    RGBLIGHT_ENABLE = yes
+```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,   \

+    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
 
-In order to use the underglow animation functions, you need to have `#define RGBLIGHT_ANIMATIONS` in your `config.h`.
+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.
 
-Please add the following options into your config.h, and set them up according your hardware configuration. These settings are for the `F4` pin by default:
+You can set the Clipping Range by executing the following code.
 
-    #define RGB_DI_PIN F4     // The pin your RGB strip is wired to
-    #define RGBLED_NUM 14     // Number of LEDs
+```c
+// some soruce
+  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
 
-You'll need to edit `RGB_DI_PIN` to the pin you have your `DI` on your RGB strip wired to.
+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.
