+# QMK Breaking Changes - 2022 May 28 Changelog
+
+## Notable Features :id=notable-features
+
+### Caps Word ([#16588](https://github.com/qmk/qmk_firmware/pull/16588)) :id=caps-word
+
+This is a new feature that allows for capslock-like functionality that turns itself off at the end of the word.
+
+For instance, if you wish to type "QMK" without holding shift the entire time, you can either tap both left and right shift, or double-tap shift, to turn on _Caps Word_ -- then type `qmk` (lowercase) without holding shift. Once you hit any key other than `a`--`z`, `0`--`9`, `-`, `_`, delete, or backspace, this will go back to normal typing!
+
+There are other activation mechanisms as well as configurable options like timeout and the like -- see the [Caps Word documentation](feature_caps_word.md) for more information.
+
+### Quantum Painter ([#10174](https://github.com/qmk/qmk_firmware/pull/10174)) :id=quantum-painter
+
+QMK has had support for small OLED displays for some time now, but hasn't really gained too much ability to draw to panels other than the SSD1306 or SH1106 panels.
+
+Quantum Painter is a new drawing subsystem available to suitable ARM and RISC-V boards that is capable of drawing to large panel RGB LCDs and RGB OLEDs. It also allows for a lot more flexibility with a larger set of drawing APIs -- lines, rectangles, circles, ellipses, text, images, and even animations.
+
+The QMK CLI has new commands added to be able to generate images and fonts for Quantum Painter to digest -- it's even capable of converting animated gifs for display on screen.
+
+See the [Quantum Painter documentation](quantum_painter.md) for more information on how to set up the displays as well as how to convert images and fonts.
+
+!> Quantum Painter is not supported on AVR due to complexity and size constraints. Boards based on AVR such as ProMicro or Elite-C builds will not be able to leverage Quantum Painter.
+
+### Encoder Mapping ([#13286](https://github.com/qmk/qmk_firmware/pull/13286)) :id=encoder-mapping
+
+One of the long-standing complaints with Encoders is that there has been no easy way to configure them in user keymaps. [#13286](https://github.com/qmk/qmk_firmware/pull/13286) added support for [Encoder Mapping](feature_encoders.md#encoder-map), which allows users to define encoder functionality in a similar way to their normal keymap.
+
+!> This is not yet supported by QMK Configurator. It is also unlikely to ever be supported by VIA.
+
+## Changes Requiring User Action :id=changes-requiring-user-action
+
+### `RESET` => `QK_BOOT` ([#17037](https://github.com/qmk/qmk_firmware/pull/17037)) :id=reset-2-qk_boot
+
+QMK is always in the process of picking up support for new hardware platforms. One of the side-effects for future integrations has shown that QMK's usage of `RESET` as a keycode is causing naming collisions. As a result, [#17037](https://github.com/qmk/qmk_firmware/pull/17037) changed usages of `RESET` to the new keycode `QK_BOOT` in the majority of default-like keymaps. At this stage the old keycode is still usable but will likely be removed in the next breaking changes cycle. Users with keymaps containing `RESET` should also move to `QK_BOOT`.
+
+### Sendstring keycode overhaul ([#16941](https://github.com/qmk/qmk_firmware/pull/16941)) :id=sendstring-keycodes
+
+Some keycodes used with `SEND_STRING` and its relatives have been deprecated and may have their old keycode usages removed at a later date. The list of [deprecated keycodes](https://github.com/qmk/qmk_firmware/blob/ebd402788346aa6e88bde1486b2a835684d40d39/quantum/send_string_keycodes.h#L456-L505) should be consulted to determine if you're using one of the older names (the first identifier after `#define`) -- you should swap to the newer variant (the second identifier on the same line).
+
+### Pillow Installation ([#17133](https://github.com/qmk/qmk_firmware/pull/17133)) :id=pillow-install
+
+The merge of Quantum Painter added some new dependencies in the QMK CLI, most notably _Pillow_, which requires some installation in order for the CLI to function. If you've got an existing installation, you'll need to run some commands in order to get things working:
+
+On Windows, if using _QMK MSYS_ or _msys2_, you'll need to run the following command:
+
+```sh
+pacman --needed --noconfirm --disable-download-timeout -S mingw-w64-x86_64-python-pillow
+python3 -m pip install --upgrade qmk
+```
+
+On macOS:
+
+```sh
+brew update
+brew upgrade qmk/qmk/qmk
+```
+
+On Linux or WSL:
+
+```sh
+python3 -m pip install --user --upgrade qmk
+```
+
+### Updated Keyboard Codebases :id=updated-keyboard-codebases
+
+The following keyboards have had their source moved within QMK:

+# Caps Word
+
+It is often useful to type a single word in all capitals, for instance
+abbreviations like "QMK", or in code, identifiers like `KC_SPC`. "Caps Word" is
+a modern alternative to Caps Lock:
+
+* Letters are capitalized while active, and Caps Word automatically disables
+  itself at the end of the word. That is, it stops by default once a space or
+  any key other than `a`--`z`, `0`--`9`, `-`, `_`, delete, or backspace is
+  pressed. Caps Word also disables itself if the keyboard is idle for 5 seconds.
+  This is configurable, see below.
+
+* To avoid requiring a dedicated key for Caps Word, there is an option
+  (`BOTH_SHIFTS_TURNS_ON_CAPS_WORD`) to activate Caps Word by simultaneously
+  pressing both shift keys. See below for other options.
+
+* The implementation does not use the Caps Lock (`KC_CAPS`) keycode. Caps Word
+  works even if you're remapping Caps Lock at the OS level to Ctrl or something
+  else, as Emacs and Vim users often do.
+
+
+## How do I enable Caps Word :id=how-do-i-enable-caps-word
+
+In your `rules.mk`, add:
+
+```make
+CAPS_WORD_ENABLE = yes
+```
+
+Next, use one the following methods to activate Caps Word:
+
+* **Activate by pressing a key**: Use the `CAPS_WORD` keycode (short
+  alias `CAPSWRD`) in your keymap.
+
+* **Activate by pressing Left Shift + Right Shift**: Add `#define
+  BOTH_SHIFTS_TURNS_ON_CAPS_WORD` to config.h. You may also need to disable or
+  reconfigure Command, details below. Then, simultaneously pressing both left
+  and right shifts turns on Caps Word. This method works with the plain
+  `KC_LSFT` and `KC_RSFT` keycodes as well as one-shot shifts and Space Cadet
+  shifts. If your shift keys are mod-taps, hold both shift mod-tap keys until
+  the tapping term, then release them.
+
+* **Activate by double tapping Left Shift**: Add `#define
+  DOUBLE_TAP_SHIFT_TURNS_ON_CAPS_WORD` config.h. Then, double tapping Left Shift
+  turns on Caps Word. This method works with `KC_LSFT` or one-shot Left Shift
+  `OSM(MOD_LSFT)`. To count as a double tap, the maximum time in milliseconds
+  between taps is `TAPPING_TERM`, or if using `TAPPING_TERM_PER_KEY`, the time
+  returned by `get_tapping_term()` for the shift keycode being tapped.
+
+* **Custom activation**: You can activate Caps Word from code by calling
+  `caps_word_on()`. This may be used to activate Caps Word through [a
+  combo](feature_combo.md) or [tap dance](feature_tap_dance.md) or any means
+  you like.
+
+### Troubleshooting: Command :id=troubleshooting-command
+
+When using `BOTH_SHIFTS_TURNS_ON_CAPS_WORD`, you might see a compile message
+**"BOTH_SHIFTS_TURNS_ON_CAPS_WORD and Command should not be enabled at the same
+time, since both use the Left Shift + Right Shift key combination."**
+
+Many keyboards enable the [Command feature](feature_command.md), which by
+default is also activated using the Left Shift + Right Shift key combination. To
+fix this conflict, please disable Command by adding in rules.mk: 
+
+```make
+COMMAND_ENABLE = no
+```
+
+Or configure Command to use another key combination like Left Ctrl + Right Ctrl
+by defining `IS_COMMAND()` in config.h:
+
+```c
+// Activate Command with Left Ctrl + Right Ctrl.
+#define IS_COMMAND() (get_mods() == MOD_MASK_CTRL)
+```
+
+
+## Customizing Caps Word :id=customizing-caps-word
+
+### Idle timeout :id=idle-timeout
+
+Caps Word turns off automatically if no keys are pressed for
+`CAPS_WORD_IDLE_TIMEOUT` milliseconds. The default is 5000 (5 seconds).
+Configure the timeout duration in config.h, for instance 
+
+```c
+#define CAPS_WORD_IDLE_TIMEOUT 3000  // 3 seconds.
+```
+
+Setting `CAPS_WORD_IDLE_TIMEOUT` to 0 configures Caps Word to never time out.
+Caps Word then remains active indefinitely until a word breaking key is pressed.
+
+
+### Functions :id=functions
+
+Functions to manipulate Caps Word:
+
+| Function                | Description                                    |
+|-------------------------|------------------------------------------------|
+| `caps_word_on()`        | Turns Caps Word on.                            |
+| `caps_word_off()`       | Turns Caps Word off.                           |
+| `caps_word_toggle()`    | Toggles Caps Word.                             |
+| `is_caps_word_on()`     | Returns true if Caps Word is currently on.     |
+
+
+### Configure which keys are "word breaking" :id=configure-which-keys-are-word-breaking
+
+You can define the `caps_word_press_user(uint16_t keycode)` callback to
+configure which keys should be shifted and which keys are considered "word
+breaking" and stop Caps Word.
+
+The callback is called on every key press while Caps Word is active. When the
+key should be shifted (that is, a letter key), the callback should call
+`add_weak_mods(MOD_BIT(KC_LSFT))` to shift the key. Returning true continues the
+current "word," while returning false is "word breaking" and deactivates Caps
+Word. The default callback is
+
+```c
+bool caps_word_press_user(uint16_t keycode) {
+    switch (keycode) {
+        // Keycodes that continue Caps Word, with shift applied.
+        case KC_A ... KC_Z:
+        case KC_MINS:
+            add_weak_mods(MOD_BIT(KC_LSFT));  // Apply shift to next key.
+            return true;
+
+        // Keycodes that continue Caps Word, without shifting.
+        case KC_1 ... KC_0:
+        case KC_BSPC:
+        case KC_DEL:
+        case KC_UNDS:
+            return true;
+
+        default:
+            return false;  // Deactivate Caps Word.
+    }
+}
+```
+
+
+### Representing Caps Word state :id=representing-caps-word-state
+
+Define `caps_word_set_user(bool active)` to get callbacks when Caps Word turns
+on or off. This is useful to represent the current Caps Word state, e.g. by
+setting an LED or playing a sound. In your keymap, define
+
+```c
+void caps_word_set_user(bool active) {
+    if (active) {
+        // Do something when Caps Word activates.
+    } else {
+        // Do something when Caps Word deactivates.
+    }
+}
+```
+

-# HD44780 LCD Displays
+# HD44780 LCD Driver
 
-This is an integration of Peter Fleury's LCD library. This page will explain the basics. [For in depth documentation visit his page.](http://www.peterfleury.epizy.com/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)
+## Supported Hardware
 
-You can enable support for HD44780 Displays by setting the `HD44780_ENABLE` flag in your keyboards `rules.mk` to yes.
+LCD modules using [HD44780U](https://www.sparkfun.com/datasheets/LCD/HD44780.pdf) IC or equivalent, communicating in 4-bit mode.
 
-## Configuration

+|2004A |20x4, 5x8 dots|Untested, not currently supported|
 
-You will need to configure the pins used by your display, and its number of lines and columns in your keyboard's `config.h`.
+To run these modules at 3.3V, an additional MAX660 voltage converter IC must be soldered on, along with two 10µF capacitors. See [this page](https://www.codrey.com/electronic-circuits/hack-your-16x2-lcd/) for more details.

-Should you need to configure other properties you can copy them from `quantum/hd44780.h` and set them in your `config.h`
 
 ## Usage
 
-To initialize your display, call `lcd_init()` with one of these parameters:
+Add the following to your `rules.mk`:
-````
-LCD_DISP_OFF             : display off
-LCD_DISP_ON              : display on, cursor off
-LCD_DISP_ON_CURSOR       : display on, cursor on
-LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing
-````
-This is best done in your keyboards `matrix_init_kb` or your keymaps `matrix_init_user`.  
-It is advised to clear the display before use.  
-To do so call `lcd_clrscr()`.
 
-To now print something to your Display you first call `lcd_gotoxy(column, line)`. To go to the start of the first line you would call `lcd_gotoxy(0, 0)` and then print a string with `lcd_puts("example string")`.
+```make
+HD44780_ENABLE = yes
+```
 
-There are more methods available to control the display. [For in depth documentation please visit the linked page.](http://www.peterfleury.epizy.com/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)

+## Examples
+
+### Hello World
+
+Add the following to your `keymap.c`:
+
+```c
+void keyboard_post_init_user(void) {
+    hd44780_init(true, true); // Show blinking cursor

+
+### Custom Character Definition
+
+Up to eight custom characters can be defined. This data is stored in the Character Generator RAM (CGRAM), and is not persistent across power cycles.
+
+This example defines the QMK Psi as the first custom character. The first 16 positions in the character set are reserved for the eight custom characters duplicated.

 `SH_TT` swap-hands tap-toggle key is similar to [layer tap-toggle](feature_layers.md?id=switching-and-toggling-layers). Tapping repeatedly (5 taps by default) will toggle swap-hands on or off, like `SH_TG`. Tap-toggle count can be changed by defining a value for `TAPPING_TOGGLE`.
+
+## Encoder Mapping
+
+When using an encoder mapping, it's also able to handle swapping encoders between sides, too.
+
+Encoder indexes are defined as left-to-right, and the extent of the array needs to match the number of encoders on the keyboard.
+
+As an example, if a split keyboard has a single encoder per side, you can swap the order by using the following code in your keymap:
+```c
+#if defined(SWAP_HANDS_ENABLE) && defined(ENCODER_MAP_ENABLE)
+const uint8_t PROGMEM encoder_hand_swap_config[NUM_ENCODERS] = { 1, 0 };
+#endif
+```

-### `send_unicode_hex_string()` (Deprecated)
-
-Similar to `send_unicode_string()`, but the characters are represented by their Unicode code points, written in hexadecimal and separated by spaces. For example, the table flip above would be achieved with:
-
-```c
-send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B");
-```
-
-An easy way to convert your Unicode string to this format is to use [this site](https://r12a.github.io/app-conversion/) and take the result in the "Hex/UTF-32" section.

 ## Additional Language Support
 
 In `quantum/keymap_extras`, you'll see various language files — these work the same way as the ones for alternative layouts such as Colemak or BÉPO. When you include one of these language headers, you gain access to keycodes specific to that language / national layout. Such keycodes are defined by a 2-letter country/language code, followed by an underscore and a 4-letter abbreviation of the character to which the key corresponds. For example, including `keymap_french.h` and using `FR_UGRV` in your keymap will output `ù` when typed on a system with a native French AZERTY layout.

 ## 追加の言語サポート
 
 `quantum/keymap_extras` には、様々な言語ファイルがあります — これらは Colemak または BÉPO のような代替レイアウトのファイルと同じように動作します。これらの言語ヘッダのいずれかを `#include` すると、その言語/国のレイアウトに固有のキーコードにアクセスできます。このようなキーコードは、2文字の国/言語コードの後に、アンダースコアとキーが対応する4文字の略語が続くことで定義されます。例えば、キーマップに `keymap_french.h` を含め、`FR_UGRV` を使うと、ネイティブのフランス語 AZERTY レイアウトを使うシステムで入力すると、`ù` が出力されます。

-独自の MIDI デバイスを実装する時に、関数を使います。
-
-実際にデバイスを介してバイトを送信するために、送信関数を設定します。このメソッドは、このデバイスで例えば midi_send_cc のような送信関数を呼ぶ時に呼ばれます。
-
-midi_device_input を使ってデバイスからの入力データを処理し、それをデバイスに関連付けられたコールバックで渡します。
-
-デバイスのプロセス関数の最初に呼び出される関数が必要な場合、midi_device_set_pre_input_process_func を使います。通常、入力をポーリングして midi_device_input に渡します。

+# Quantum Painter :id=quantum-painter
+
+Quantum Painter is the standardised API for graphical displays. It currently includes support for basic drawing primitives, as well as custom images, animations, and fonts.
+
+Due to the complexity, there is no support for Quantum Painter on AVR-based boards.
+
+To enable overall Quantum Painter to be built into your firmware, add the following to `rules.mk`:
+
+```make
+QUANTUM_PAINTER_ENABLE = yes
+QUANTUM_PAINTER_DRIVERS = ......
+```
+
+You will also likely need to select an appropriate driver in `rules.mk`, which is listed below.
+
+!> Quantum Painter is not currently integrated with system-level operations such as disabling displays after a configurable timeout, or when the keyboard goes into suspend. Users will need to handle this manually at the current time.
+
+The QMK CLI can be used to convert from normal images such as PNG files or animated GIFs, as well as fonts from TTF files.
+
+Hardware supported:

+```
+
+### `qmk painter-make-font-image`
+
+This command converts a TTF font to an intermediate format for editing, before converting to the QFF File Format.
+
+**Usage**:
+
+```
+usage: qmk painter-make-font-image [-h] [-a] [-u UNICODE_GLYPHS] [-n] [-s SIZE] -o OUTPUT -f FONT
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -a, --no-aa           Disable anti-aliasing on fonts.
+  -u UNICODE_GLYPHS, --unicode-glyphs UNICODE_GLYPHS
+                        Also generate the specified unicode glyphs.
+  -n, --no-ascii        Disables output of the full ASCII character set (0x20..0x7E), exporting only the glyphs specified.
+  -s SIZE, --size SIZE  Specify font size. Default 12.
+  -o OUTPUT, --output OUTPUT
+                        Specify output image path.
+  -f FONT, --font FONT  Specify input font file.
+```
+
+The `FONT` argument is generally a TrueType Font file (TTF).
+
+The `OUTPUT` argument is the output image to generate, generally something like `my_font.png`.
+
+The `UNICODE_GLYPHS` argument allows for specifying extra unicode glyphs to generate, and accepts a string.
+
+**Examples**:
+
+```
+$ qmk painter-make-font-image --font NotoSans-ExtraCondensedBold.ttf --size 11 -o noto11.png --unicode-glyphs "ĄȽɂɻɣɈʣ"
+```
+
+### `qmk painter-convert-font-image`
+
+This command converts an intermediate font image to the QFF File Format.
+
+This command expects an image that conforms to the following format:
+
+* Top-left pixel (at `0,0`) is the "delimiter" color:
+    * Each glyph in the font starts when a pixel of this color is found on the first row
+    * The first row is discarded when converting to the QFF format
+* The number of delimited glyphs must match the supplied arguments to the command:
+    * The full ASCII set `0x20..0x7E` (if `--no-ascii` was not specified)
+    * The corresponding number of unicode glyphs if any were specified with `--unicode-glyphs`
+* The order of the glyphs matches the ASCII set, if any, followed by the Unicode glyph set, if any.
+
+**Usage**:
+
+```
+usage: qmk painter-convert-font-image [-h] [-r] -f FORMAT [-u UNICODE_GLYPHS] [-n] [-o OUTPUT] [-i INPUT]
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -r, --no-rle          Disable the use of RLE to minimise converted image size.
+  -f FORMAT, --format FORMAT
+                        Output format, valid types: pal256, pal16, pal4, pal2, mono256, mono16, mono4, mono2
+  -u UNICODE_GLYPHS, --unicode-glyphs UNICODE_GLYPHS
+                        Also generate the specified unicode glyphs.
+  -n, --no-ascii        Disables output of the full ASCII character set (0x20..0x7E), exporting only the glyphs specified.
+  -o OUTPUT, --output OUTPUT
+                        Specify output directory. Defaults to same directory as input.
+  -i INPUT, --input INPUT
+                        Specify input graphic file.
+```
+
+The same arguments for `--no-ascii` and `--unicode-glyphs` need to be specified, as per `qmk painter-make-font-image`.
+
+**Examples**:
+
+```
+$ cd /home/qmk/qmk_firmware/keyboards/my_keeb

+All APIs require a `painter_device_t` object as their first parameter -- this object comes from the specific device initialisation, and instructions on creating it can be found in each driver's respective section.
+
+To use any of the APIs, you need to include `qp.h`:
+```c
+#include <qp.h>
+```
+
+### General Notes :id=quantum-painter-api-general
+
+The coordinate system used in Quantum Painter generally accepts `left`, `top`, `right`, and `bottom` instead of x/y/width/height, and each coordinate is inclusive of where pixels should be drawn. This is required as some datatypes used by display panels have a maximum value of `255` -- for any value or geometry extent that matches `256`, this would be represented as a `0`, instead.
+
+?> Drawing a horizontal line 8 pixels long, starting from 4 pixels inside the left side of the display, will need `left=4`, `right=11`.
+
+All color data matches the standard QMK HSV triplet definitions:
+
+* Hue is of the range `0...255` and is internally mapped to 0...360 degrees.
+* Saturation is of the range `0...255` and is internally mapped to 0...100% saturation.
+* Value is of the range `0...255` and is internally mapped to 0...100% brightness.
+
+?> Colors used in Quantum Painter are not subject to the RGB lighting CIE curve, if it is enabled.
+
+### Device Control :id=quantum-painter-api-device-control
+
+#### Display Initialisation :id=quantum-painter-api-init
+
+```c
+bool qp_init(painter_device_t device, painter_rotation_t rotation);
+```
+
+The `qp_init` function is used to initialise a display device after it has been created. This accepts a rotation parameter (`QP_ROTATION_0`, `QP_ROTATION_90`, `QP_ROTATION_180`, `QP_ROTATION_270`), which makes sure that the orientation of what's drawn on the display is correct.
+
+```c
+static painter_device_t display;
+void keyboard_post_init_kb(void) {
+    display = qp_make_.......;         // Create the display
+    qp_init(display, QP_ROTATION_0);   // Initialise the display
+}
+```
+
+#### Display Power :id=quantum-painter-api-power
+
+```c
+bool qp_power(painter_device_t device, bool power_on);
+```
+
+The `qp_power` function instructs the display whether or not the display panel should be on or off.
+
+!> If there is a separate backlight controlled through the normal QMK backlight API, this is not controlled by the `qp_power` function and needs to be manually handled elsewhere.
+
+```c
+static uint8_t last_backlight = 255;
+void suspend_power_down_user(void) {
+    if (last_backlight == 255) {
+        last_backlight = get_backlight_level();
+    }
+    backlight_set(0);
+    rgb_matrix_set_suspend_state(true);
+    qp_power(display, false);
+}
+
+void suspend_wakeup_init_user(void) {
+    qp_power(display, true);
+    rgb_matrix_set_suspend_state(false);
+    if (last_backlight != 255) {
+        backlight_set(last_backlight);
+    }
+    last_backlight = 255;
+}
+```
+
+#### Display Clear :id=quantum-painter-api-clear
+
+```c
+bool qp_clear(painter_device_t device);
+```
+
+The `qp_clear` function clears the display's screen.
+
+#### Display Flush :id=quantum-painter-api-flush
+
+```c
+bool qp_flush(painter_device_t device);
+```
+
+The `qp_flush` function ensures that all drawing operations are "pushed" to the display. This should be done as the last operation whenever a sequence of draws occur, and guarantees that any changes are applied.
+
+!> Some display panels may seem to work even without a call to `qp_flush` -- this may be because the driver cannot queue drawing operations and needs to display them immediately when invoked. In general, calling `qp_flush` at the end is still considered "best practice".
+
+```c
+void housekeeping_task_user(void) {
+    static uint32_t last_draw = 0;
+    if (timer_elapsed32(last_draw) > 33) { // Throttle to 30fps
+        last_draw = timer_read32();
+        // Draw a rect based off the current RGB color
+        qp_rect(display, 0, 7, 0, 239, rgb_matrix_get_hue(), 255, 255);
+        qp_flush(display);
+    }
+}
+```
+
+### Drawing Primitives :id=quantum-painter-api-primitives
+
+#### Set Pixel :id=quantum-painter-api-setpixel
+
+```c
+bool qp_setpixel(painter_device_t device, uint16_t x, uint16_t y, uint8_t hue, uint8_t sat, uint8_t val);
+```
+
+The `qp_setpixel` can be used to set a specific pixel on the screen to the supplied color.
+
+?> Using `qp_setpixel` for large amounts of drawing operations is inefficient and should be avoided unless they cannot be achieved with other drawing APIs.
+
+```c
+void housekeeping_task_user(void) {
+    static uint32_t last_draw = 0;
+    if (timer_elapsed32(last_draw) > 33) { // Throttle to 30fps
+        last_draw = timer_read32();
+        // Draw a 240px high vertical rainbow line on X=0:
+        for (int i = 0; i < 239; ++i) {
+            qp_setpixel(display, 0, i, i, 255, 255);
+        }
+        qp_flush(display);
+    }
+}
+```
+
+#### Draw Line :id=quantum-painter-api-line
+
+```c
+bool qp_line(painter_device_t device, uint16_t x0, uint16_t y0, uint16_t x1, uint16_t y1, uint8_t hue, uint8_t sat, uint8_t val);
+```
+
+The `qp_line` can be used to draw lines on the screen with the supplied color.
+
+```c
+void housekeeping_task_user(void) {
+    static uint32_t last_draw = 0;
+    if (timer_elapsed32(last_draw) > 33) { // Throttle to 30fps
+        last_draw = timer_read32();
+        // Draw 8px-wide rainbow down the left side of the display
+        for (int i = 0; i < 239; ++i) {
+            qp_line(display, 0, i, 7, i, i, 255, 255);
+        }
+        qp_flush(display);
+    }
+}
+```
+
+#### Draw Rect :id=quantum-painter-api-rect
+
+```c
+bool qp_rect(painter_device_t device, uint16_t left, uint16_t top, uint16_t right, uint16_t bottom, uint8_t hue, uint8_t sat, uint8_t val, bool filled);
+```
+
+The `qp_rect` can be used to draw rectangles on the screen with the supplied color, with or without a background fill. If not filled, any pixels inside the rectangle will be left as-is.
+
+```c
+void housekeeping_task_user(void) {
+    static uint32_t last_draw = 0;
+    if (timer_elapsed32(last_draw) > 33) { // Throttle to 30fps
+        last_draw = timer_read32();
+        // Draw 8px-wide rainbow filled rectangles down the left side of the display
+        for (int i = 0; i < 239; i+=8) {
+            qp_rect(display, 0, i, 7, i+7, i, 255, 255, true);
+        }
+        qp_flush(display);
+    }
+}
+```
+
+#### Draw Circle :id=quantum-painter-api-circle
+
+```c
+bool qp_circle(painter_device_t device, uint16_t x, uint16_t y, uint16_t radius, uint8_t hue, uint8_t sat, uint8_t val, bool filled);
+```
+
+The `qp_circle` can be used to draw circles on the screen with the supplied color, with or without a background fill. If not filled, any pixels inside the circle will be left as-is.
+
+```c
+void housekeeping_task_user(void) {
+    static uint32_t last_draw = 0;
+    if (timer_elapsed32(last_draw) > 33) { // Throttle to 30fps
+        last_draw = timer_read32();
+        // Draw r=4 filled circles down the left side of the display
+        for (int i = 0; i < 239; i+=8) {
+            qp_circle(display, 4, 4+i, 4, i, 255, 255, true);
+        }
+        qp_flush(display);
+    }
+}
+```
+
+#### Draw Ellipse :id=quantum-painter-api-ellipse
+
+```c
+bool qp_ellipse(painter_device_t device, uint16_t x, uint16_t y, uint16_t sizex, uint16_t sizey, uint8_t hue, uint8_t sat, uint8_t val, bool filled);
+```
+
+The `qp_ellipse` can be used to draw ellipses on the screen with the supplied color, with or without a background fill. If not filled, any pixels inside the ellipses will be left as-is.
+
+```c
+void housekeeping_task_user(void) {
+    static uint32_t last_draw = 0;
+    if (timer_elapsed32(last_draw) > 33) { // Throttle to 30fps
+        last_draw = timer_read32();
+        // Draw 16x8 filled ellipses down the left side of the display
+        for (int i = 0; i < 239; i+=8) {
+            qp_ellipse(display, 8, 4+i, 16, 8, i, 255, 255, true);
+        }
+        qp_flush(display);
+    }
+}
+```
+
+### Image Functions :id=quantum-painter-api-images
+
+#### Load Image :id=quantum-painter-api-load-image
+
+```c
+painter_image_handle_t qp_load_image_mem(const void *buffer);
+```
+
+The `qp_load_image_mem` function loads a QGF image from memory or flash.
+
+`qp_load_image_mem` returns a handle to the loaded image, which can then be used to draw to the screen using `qp_drawimage`, `qp_drawimage_recolor`, `qp_animate`, or `qp_animate_recolor`. If an image is no longer required, it can be unloaded by calling `qp_close_image` below. 
+
+See the [CLI Commands](quantum_painter.md?id=quantum-painter-cli) for instructions on how to convert images to [QGF](quantum_painter_qgf.md).
+
+?> The total number of images available to load at any one time is controlled by the configurable option `QUANTUM_PAINTER_NUM_IMAGES` in the table above. If more images are required, the number should be increased in `config.h`.
+
+Image information is available through accessing the handle:
+
+| Property    | Accessor             |
+|-------------|----------------------|
+| Width       | `image->width`       |
+| Height      | `image->height`      |
+| Frame Count | `image->frame_count` |
+
+#### Unload Image :id=quantum-painter-api-close-image
+
+```c
+bool qp_close_image(painter_image_handle_t image);
+```
+
+The `qp_close_image` function releases resources related to the loading of the supplied image.
+
+#### Draw image :id=quantum-painter-api-draw-image
+
+```c
+bool qp_drawimage(painter_device_t device, uint16_t x, uint16_t y, painter_image_handle_t image);
+bool qp_drawimage_recolor(painter_device_t device, uint16_t x, uint16_t y, painter_image_handle_t image, uint8_t hue_fg, uint8_t sat_fg, uint8_t val_fg, uint8_t hue_bg, uint8_t sat_bg, uint8_t val_bg);
+```
+
+The `qp_drawimage` and `qp_drawimage_recolor` functions draw the supplied image to the screen at the supplied location, with the latter function allowing for monochrome-based images to be recolored.
+
+```c
+// Draw an image on the bottom-right of the 240x320 display on initialisation
+static painter_image_handle_t my_image;
+void keyboard_post_init_kb(void) {
+    my_image = qp_load_image_mem(gfx_my_image);
+    if (my_image != NULL) {
+        qp_drawimage(display, (239 - my_image->width), (319 - my_image->height), my_image);
+    }
+}
+```
+
+#### Animate Image :id=quantum-painter-api-animate-image
+
+```c
+deferred_token qp_animate(painter_device_t device, uint16_t x, uint16_t y, painter_image_handle_t image);
+deferred_token qp_animate_recolor(painter_device_t device, uint16_t x, uint16_t y, painter_image_handle_t image, uint8_t hue_fg, uint8_t sat_fg, uint8_t val_fg, uint8_t hue_bg, uint8_t sat_bg, uint8_t val_bg);
+```
+
+The `qp_animate` and `qp_animate_recolor` functions draw the supplied image to the screen at the supplied location, with the latter function allowing for monochrome-based animations to be recolored. They also set up internal timing such that each frame is rendered at the correct time as per the animated image.
+
+Once an image has been set to animate, it will loop indefinitely until stopped, with no user intervention required.
+
+Both functions return a `deferred_token`, which can then be used to stop the animation, using `qp_stop_animation` below.
+
+```c
+// Animate an image on the bottom-right of the 240x320 display on initialisation
+static painter_image_handle_t my_image;
+static deferred_token my_anim;
+void keyboard_post_init_kb(void) {
+    my_image = qp_load_image_mem(gfx_my_image);
+    if (my_image != NULL) {
+        my_anim = qp_animate(display, (239 - my_image->width), (319 - my_image->height), my_image);
+    }
+}
+```
+
+#### Stop Animation :id=quantum-painter-api-stop-animation
+
+```c
+void qp_stop_animation(deferred_token anim_token);
+```
+
+The `qp_stop_animation` function stops the previously-started animation.
+```c
+void housekeeping_task_user(void) {
+    if (some_random_stop_reason) {
+        qp_stop_animation(my_anim);
+    }
+}
+```
+
+### Font Functions :id=quantum-painter-api-fonts
+
+#### Load Font :id=quantum-painter-api-load-font
+
+```c
+painter_font_handle_t qp_load_font_mem(const void *buffer);
+```
+
+The `qp_load_font_mem` function loads a QFF font from memory or flash.
+
+`qp_load_font_mem` returns a handle to the loaded font, which can then be measured using `qp_textwidth`, or drawn to the screen using `qp_drawtext`, or `qp_drawtext_recolor`. If a font is no longer required, it can be unloaded by calling `qp_close_font` below. 
+
+See the [CLI Commands](quantum_painter.md?id=quantum-painter-cli) for instructions on how to convert TTF fonts to [QFF](quantum_painter_qff.md).
+
+?> The total number of fonts available to load at any one time is controlled by the configurable option `QUANTUM_PAINTER_NUM_FONTS` in the table above. If more fonts are required, the number should be increased in `config.h`.
+
+Font information is available through accessing the handle:
+
+| Property    | Accessor             |
+|-------------|----------------------|
+| Line Height | `image->line_height` |
+
+#### Unload Font :id=quantum-painter-api-close-font
+
+```c
+bool qp_close_font(painter_font_handle_t font);
+```
+
+The `qp_close_font` function releases resources related to the loading of the supplied font.
+
+#### Measure Text :id=quantum-painter-api-textwidth
+
+```c
+int16_t qp_textwidth(painter_font_handle_t font, const char *str);
+```
+
+The `qp_textwidth` function allows measurement of how many pixels wide the supplied string would result in, for the given font.
+
+#### Draw Text :id=quantum-painter-api-drawtext
+
+```c
+int16_t qp_drawtext(painter_device_t device, uint16_t x, uint16_t y, painter_font_handle_t font, const char *str);
+int16_t qp_drawtext_recolor(painter_device_t device, uint16_t x, uint16_t y, painter_font_handle_t font, const char *str, uint8_t hue_fg, uint8_t sat_fg, uint8_t val_fg, uint8_t hue_bg, uint8_t sat_bg, uint8_t val_bg);
+```
+
+The `qp_drawtext` and `qp_drawtext_recolor` functions draw the supplied string to the screen at the given location using the font supplied, with the latter function allowing for monochrome-based fonts to be recolored.
+
+```c
+// Draw a text message on the bottom-right of the 240x320 display on initialisation
+static painter_font_handle_t my_font;
+void keyboard_post_init_kb(void) {
+    my_font = qp_load_font_mem(font_opensans);
+    if (my_font != NULL) {
+        static const char *text = "Hello from QMK!";
+        int16_t width = qp_textwidth(my_font, text);
+        qp_drawtext(display, (239 - width), (319 - my_font->line_height), my_font, text);
+    }
+}
+```
+
+### Advanced Functions :id=quantum-painter-api-advanced
+
+#### Get Geometry :id=quantum-painter-api-get-geometry
+
+```c
+void qp_get_geometry(painter_device_t device, uint16_t *width, uint16_t *height, painter_rotation_t *rotation, uint16_t *offset_x, uint16_t *offset_y);
+```
+
+The `qp_get_geometry` function allows external code to retrieve the current width, height, rotation, and drawing offsets.
+
+#### Set Viewport Offsets :id=quantum-painter-api-set-viewport
+
+```c
+void qp_set_viewport_offsets(painter_device_t device, uint16_t offset_x, uint16_t offset_y);
+```
+
+The `qp_set_viewport_offsets` function can be used to offset all subsequent drawing operations. For example, if a display controller is internally 240x320, but the display panel is 240x240 and has a Y offset of 80 pixels, you could invoke `qp_set_viewport_offsets(display, 0, 80);` and the drawing positioning would be corrected.
+
+#### Set Viewport :id=quantum-painter-api-viewport
+
+```c
+bool qp_viewport(painter_device_t device, uint16_t left, uint16_t top, uint16_t right, uint16_t bottom);
+```
+
+The `qp_viewport` function controls where raw pixel data is written to.
+
+#### Stream Pixel Data :id=quantum-painter-api-pixdata
+
+```c
+bool qp_pixdata(painter_device_t device, const void *pixel_data, uint32_t native_pixel_count);
+```
+
+The `qp_pixdata` function allows raw pixel data to be streamed to the display. It requires a native pixel count rather than the number of bytes to transfer, to ensure display panel data alignment is respected. E.g. for display panels using RGB565 internal format, sending 10 pixels will result in 20 bytes of transfer.
+
+!> Under normal circumstances, users will not need to manually call either `qp_viewport` or `qp_pixdata`. These allow for writing of raw pixel information, in the display panel's native format, to the area defined by the viewport.
+
+## Quantum Painter Display Drivers :id=quantum-painter-drivers
+
+### Common: Standard TFT (SPI + D/C + RST)
+
+Most TFT display panels use a 5-pin interface -- SPI SCK, SPI MOSI, SPI CS, D/C, and RST pins.
+
+For these displays, QMK's `spi_master` must already be correctly configured for the platform you're building for.
+
+The pin assignments for SPI CS, D/C, and RST are specified during device construction.

+# QMK Font Format :id=qmk-font-format
+
+QMK uses a font format _("Quantum Font Format" - QFF)_ specifically for resource-constrained systems.
+
+This format is capable of encoding 1-, 2-, 4-, and 8-bit-per-pixel greyscale- and palette-based images into a font. It also includes RLE for pixel data for some basic compression.
+
+All integer values are in little-endian format.
+
+The QFF is defined in terms of _blocks_ -- each _block_ contains a _header_ and an optional _blob_ of data. The _header_ contains the block's _typeid_, and the length of the _blob_ that follows. Each block type is denoted by a different _typeid_ has its own block definition below. All blocks are defined as packed structs, containing zero padding between fields.
+
+The general structure of the file is:
+
+* _Font descriptor block_
+* _ASCII glyph block_ (optional, only if ASCII glyphs are included)
+* _Unicode glyph block_ (optional, only if Unicode glyphs are included)
+* _Font palette block_ (optional, depending on frame format)
+* _Font data block_
+
+## Block Header :id=qff-block-header
+
+The block header is identical to [QGF's block header](quantum_painter_qgf.md#qgf-block-header), and is present for all blocks, including the font descriptor.
+
+## Font descriptor block :id=qff-font-descriptor
+
+* _typeid_ = 0x00
+* _length_ = 20
+
+This block must be located at the start of the file contents, and can exist a maximum of once in an entire QGF file. It is always followed by either the _ASCII glyph table_ or the _Unicode glyph table_, depending on which glyphs are included in the font.
+
+_Block_ format:
+
+```c
+typedef struct __attribute__((packed)) qff_font_descriptor_v1_t {
+    qgf_block_header_v1_t header;               // = { .type_id = 0x00, .neg_type_id = (~0x00), .length = 20 }
+    uint24_t              magic;                // constant, equal to 0x464651 ("QFF")

+    uint32_t              neg_total_file_size;  // negated value of total_file_size, used for detecting parsing errors
+    uint8_t               line_height;          // glyph height in pixels
+    bool                  has_ascii_table;      // whether the font has an ascii table of glyphs (0x20...0x7E)
+    uint16_t              num_unicode_glyphs;   // the number of glyphs in the unicode table -- no table specified if zero
+    uint8_t               format;               // frame format, see below.
+    uint8_t               flags;                // frame flags, see below.
+    uint8_t               compression_scheme;   // compression scheme, see below.
+    uint8_t               transparency_index;   // palette index used for transparent pixels (not yet implemented)
+} qff_font_descriptor_v1_t;

+```
+
+The values for `format`, `flags`, `compression_scheme`, and `transparency_index` match [QGF's frame descriptor block](quantum_painter_qgf.md#qgf-frame-descriptor), with the exception that the `delta` flag is ignored by QFF.
+
+## ASCII glyph table :id=qff-ascii-table
+
+* _typeid_ = 0x01
+* _length_ = 290
+
+If the font contains ascii characters, the _ASCII glyph block_ must be located directly after the _font descriptor block_.

+#define QFF_GLYPH_WIDTH_BITS 6
+#define QFF_GLYPH_WIDTH_MASK ((1<<QFF_GLYPH_WIDTH_BITS)-1)

+```
+
+## Unicode glyph table :id=qff-unicode-table
+
+* _typeid_ = 0x02
+* _length_ = variable
+
+If this font contains unicode characters, the _unicode glyph block_ must be located directly after the _ASCII glyph table block_, or the _font descriptor block_ if the font does not contain ASCII characters.
+
+```c
+typedef struct __attribute__((packed)) qff_unicode_glyph_table_v1_t {

+    } glyph[N];                       // N glyphs worth of data
+} qff_unicode_glyph_table_v1_t;
+```
+
+## Font palette block :id=qff-palette-descriptor
+
+* _typeid_ = 0x03
+* _length_ = variable
+
+The _font palette block_ is identical to [QGF's frame palette block](quantum_painter_qgf.md#qgf-frame-palette-descriptor), retaining the same _typeid_ of 0x03.
+
+It is only specified in the QFF if the font is palette-based, and follows the _unicode glyph block_ if the font contains any Unicode glyphs, or the _ASCII glyph block_ if the font contains only ASCII glyphs.
+
+## Font data block :id=qff-data-descriptor
+
+* _typeid_ = 0x04
+* _length_ = variable
+
+The _font data block_ is the last block in the file and is identical to [QGF's frame data block](quantum_painter_qgf.md#qgf-frame-data-descriptor), however has a different _typeid_ of 0x04 in QFF.

+# QMK Graphics Format :id=qmk-graphics-format
+
+QMK uses a graphics format _("Quantum Graphics Format" - QGF)_ specifically for resource-constrained systems.
+
+This format is capable of encoding 1-, 2-, 4-, and 8-bit-per-pixel greyscale- and palette-based images. It also includes RLE for pixel data for some basic compression.
+
+All integer values are in little-endian format.
+
+The QGF is defined in terms of _blocks_ -- each _block_ contains a _header_ and an optional _blob_ of data. The _header_ contains the block's _typeid_, and the length of the _blob_ that follows. Each block type is denoted by a different _typeid_ has its own block definition below. All blocks are defined as packed structs, containing zero padding between fields.
+
+The general structure of the file is:
+
+* _Graphics descriptor block_
+* _Frame offset block_
+* Repeating list of frames:
+    * _Frame descriptor block_
+    * _Frame palette block_ (optional, depending on frame format)
+    * _Frame delta block_ (optional, depending on delta flag)
+    * _Frame data block_
+
+Different frames within the file should be considered "isolated" and may have their own image format and/or palette.
+
+## Block Header :id=qgf-block-header
+

+// _Static_assert(sizeof(qgf_block_header_v1_t) == 5, "qgf_block_header_v1_t must be 5 bytes in v1 of QGF");

+```c
+sprintf(wpm_str, "%03d", get_current_wpm());
+snprintf(keylog_str, sizeof(keylog_str), "%dx%d, k%2d : %c");

 If you've done all of that, and you don't want to disable features like RGB, Audio, OLEDs, etc, there are some additional options that you can add to your config.h that can help.
