+# QMK Breaking Changes - 2022 February 26 Changelog
+
+## Notable Features :id=notable-features
+
+### Default USB Polling rate now 1kHz ([#15352](https://github.com/qmk/qmk_firmware/pull/15352))
+
+The default USB Polling rate has been aligned across supported platforms to now be 1ms/1kHz.
+
+Something something *Lets go gamers!*
+
+### Split support for pointing devices ([#15304](https://github.com/qmk/qmk_firmware/pull/15304))
+
+Pointing devices can now be shared across a split keyboard with support for a single pointing device or a pointing device on each side.
+
+See the [Pointing Device](feature_pointing_device.md) documentation for further configuration options.
+
+## Changes Requiring User Action :id=changes-requiring-user-action
+
+### Legacy macro and action_function system removed ([#16025](https://github.com/qmk/qmk_firmware/pull/16025))
+
+The long time deprecated `MACRO()` and `action_get_macro` methods have been removed. Where possible, existing usages have been migrated over to core [Macros](feature_macros.md).
+
+### Create a build error if no bootloader is specified ([#16181](https://github.com/qmk/qmk_firmware/pull/16181))
+
+Bootloader configuration is no longer assumed. Keyboards must now set either:
+
+* `BOOTLOADER` within `rules.mk`
+* `bootloader` within `info.json`
+
+### Rename `AdafruitBLE` to `BluefruitLE` ([#16127](https://github.com/qmk/qmk_firmware/pull/16127))
+
+In preparation of future bluetooth work, the `AdafruitBLE` integration has been renamed to allow potential for any other Adafruit BLE products. 
+
+### Updated Keyboard Codebases :id=updated-keyboard-codebases
+
+The following keyboards have had their source moved within QMK:

-Should you need to configure other properties you can copy them from `quantum/hd44780.h` and set them in your `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.
 
 ## Usage
 
-To initialize your display, call `lcd_init()` with one of these parameters:
-````
-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()`.
+Add the following to your `rules.mk`:
 
-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)

+Sometimes your leader key is not on a comfortable place as the rest of keys on your sequence. Imagine that your leader key is one of your outer top right keys, you may need to reposition your hand just to reach your leader key.
 This can make typing the entire sequence on time hard even if you are able to type most of the sequence fast. For example, if your sequence is `Leader + asd` typing `asd` fast is very easy once you have your hands in your home row. However starting the sequence in time after moving your hand out of the home row to reach the leader key and back is not.
-To remove the stress this situation produces to your hands you can enable an infinite timeout just for the leader key. This mean that, after you hit the leader key you will have an infinite amount of time to start the rest of the sequence, allowing you to proper position your hands on the best position to type the rest of the sequence comfortably.

The rotation and invert `*_RIGHT` options are only used with `POINTING_DEVICE_COMBINED`. If using `POINTING_DEVICE_LEFT` or `POINTING_DEVICE_RIGHT` use the common configuration above to configure your pointing device.

 # Manipulating Mouse Reports
@@ -211,14 +276,14 @@ The report_mouse_t (here "mouseReport") has the following properties:
 To manually manipulate the mouse reports outside of the `pointing_device_task_*` functions, you can use:
 
 * `pointing_device_get_report()` - Returns the current report_mouse_t that represents the information sent to the host computer
-* `pointing_device_set_report(report_mouse_t newMouseReport)` - Overrides and saves the report_mouse_t to be sent to the host computer
+* `pointing_device_set_report(report_mouse_t mouse_report)` - Overrides and saves the report_mouse_t to be sent to the host computer
 * `pointing_device_send()` - Sends the mouse report to the host and zeroes out the report. 
 
 When the mouse report is sent, the x, y, v, and h values are set to 0 (this is done in `pointing_device_send()`, which can be overridden to avoid this behavior).  This way, button states persist, but movement will only occur once.  For further customization, both `pointing_device_init` and `pointing_device_task` can be overridden.
 
 Additionally, by default, `pointing_device_send()` will only send a report when the report has actually changed.  This prevents it from continuously sending mouse reports, which will keep the host system awake.  This behavior can be changed by creating your own `pointing_device_send()` function.
 
-Also, you use the `has_mouse_report_changed(new, old)` function to check to see if the report has changed.

 ## 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.

+## Advanced Settings :id=advanced-settings
+
+Each microcontroller can have multiple advanced settings regarding its GPIO. This abstraction layer does not limit the use of architecture-specific functions. Advanced users should consult the datasheet of their desired device and include any needed libraries. For AVR, the standard avr/io.h library is used; for STM32, the ChibiOS [PAL library](https://chibios.sourceforge.net/docs3/hal/group___p_a_l.html) is used.
+
+## Atomic Operation
+
+The above functions are not always guaranteed to work atomically. Therefore, if you want to prevent interruptions in the middle of operations when using multiple combinations of the above functions, use the following `ATOMIC_BLOCK_FORCEON` macro.
+
+eg.
+```c
+void some_function() {
+     // some process
+     ATOMIC_BLOCK_FORCEON {
+        // Atomic Processing
+     }
+     // some process
+}
+```
+
+`ATOMIC_BLOCK_FORCEON` forces interrupts to be disabled before the block is executed, without regard to whether they are enabled or disabled. Then, after the block is executed, the interrupt is enabled.
+
+Note that `ATOMIC_BLOCK_FORCEON` can therefore be used if you know that interrupts are enabled before the execution of the block, or if you know that it is OK to enable interrupts at the completion of the block.

-# Keyboards with AVR Processors
-
-This page describes the support for for AVR processors in QMK. AVR processors include the atmega32u4, atmega32u2, at90usb1286, and other processors from Atmel Corporation. AVR processors are 8-bit MCUs that are designed to be easy to work with. The most common AVR processors in keyboards have on-board USB and plenty of GPIO for supporting large keyboard matrices. They are the most popular MCU for use in keyboards today.
-
-If you have not yet you should read the [Keyboard Guidelines](hardware_keyboard_guidelines.md) to get a sense of how keyboards fit into QMK.
-
-## Adding Your AVR Keyboard to QMK
-
-QMK has a number of features to simplify working with AVR keyboards. For most keyboards you don't have to write a single line of code. To get started, run `qmk new-keyboard`:
-
-```
-$ qmk new-keyboard
-Ψ Generating a new QMK keyboard directory
-
-Keyboard Name: mycoolkeeb
-Keyboard Type:
-        1. avr
-        2. ps2avrgb
-Please enter your choice:  [1]
-Your Name: [John Smith]
-Ψ Copying base template files...
-Ψ Copying avr template files...
-Ψ Renaming keyboard.[ch] to mycoolkeeb.[ch]...
-Ψ Replacing %YEAR% with 2021...
-Ψ Replacing %KEYBOARD% with mycoolkeeb...
-Ψ Replacing %YOUR_NAME% with John Smith...
-
-Ψ Created a new keyboard called mycoolkeeb.
-Ψ To start working on things, `cd` into keyboards/mycoolkeeb,
-Ψ or open the directory in your preferred text editor.
-```
-
-This will create all the files needed to support your new keyboard, and populate the settings with default values. Now you just need to customize it for your keyboard.
-
-## `readme.md`
-
-This is where you'll describe your keyboard. Please follow the [Keyboard Readme Template](documentation_templates.md#keyboard-readmemd-template) when writing your `readme.md`. You're encouraged to place an image at the top of your `readme.md`, please use an external service such as [Imgur](https://imgur.com) to host the images.
-
-## `<keyboard>.c`
-
-This is where all the custom logic for your keyboard goes. Many keyboards do not need to put anything at all in here. You can learn more about writing custom logic in [Custom Quantum Functions](custom_quantum_functions.md).
-
-## `<keyboard>.h`
-
-This is the file you define your [Layout Macro(s)](feature_layouts.md) in. At minimum you should have a `#define LAYOUT` for your keyboard that looks something like this:
-
-```c
-#define LAYOUT(          \
-      k00, k01, k02,     \
-      k10,   k11         \
-) {                      \
-    { k00, k01,   k02 }, \
-    { k10, KC_NO, k11 }, \
-}
-```
-
-The first half of the `LAYOUT` pre-processor macro defines the physical arrangement of keys. The second half of the macro defines the matrix the switches are connected to. This allows you to have a physical arrangement of keys that differs from the wiring matrix.
-
-Each of the `k__` variables needs to be unique, and typically they follow the format `k<row><col>`.
-
-The physical matrix (the second half) must have a number of rows equaling `MATRIX_ROWS`, and each row must have exactly `MATRIX_COLS` elements in it. If you do not have this many physical keys you can use `KC_NO` to fill in the blank spots.
-
-## `config.h`
-
-The `config.h` file is where you configure the hardware and feature set for your keyboard. There are a lot of options that can be placed in that file, too many to list there. For a complete overview of available options see the [Config Options](config_options.md) page.
-
-### Hardware Configuration
-
-
-At the top of the `config.h` you'll find USB related settings. These control how your keyboard appears to the Operating System. If you don't have a good reason to change you should leave the `VENDOR_ID` as `0xFEED`. For the `PRODUCT_ID` you should pick a number that is not yet in use.
-
-Do change the `MANUFACTURER` and `PRODUCT` lines to accurately reflect your keyboard.
-
-```c
-#define VENDOR_ID       0xFEED
-#define PRODUCT_ID      0x6060
-#define DEVICE_VER      0x0001
-#define MANUFACTURER    You
-#define PRODUCT         my_awesome_keyboard
-```
-
-?> Windows and macOS will display the `MANUFACTURER` and `PRODUCT` in the list of USB devices. `lsusb` on Linux instead prefers the values in the list maintained by the [USB ID Repository](http://www.linux-usb.org/usb-ids.html). By default, it will only use `MANUFACTURER` and `PRODUCT` if the list does not contain that `VENDOR_ID` / `PRODUCT_ID`. `sudo lsusb -v` will show the values reported by the device, and they are also present in kernel logs after plugging it in.
-
-### Keyboard Matrix Configuration
-
-The next section of the `config.h` file deals with your keyboard's matrix. The first thing you should set is the matrix's size. This is usually, but not always, the same number of rows and columns as the physical key arrangement.
-
-```c
-#define MATRIX_ROWS 2
-#define MATRIX_COLS 3
-```
-
-Once you've defined the size of your matrix you need to define which pins on your MCU are connected to rows and columns. To do so simply specify the names of those pins:
-
-```c
-#define MATRIX_ROW_PINS { D0, D5 }
-#define MATRIX_COL_PINS { F1, F0, B0 }
-#define UNUSED_PINS
-```
-
-The number of `MATRIX_ROW_PINS` entries must be the same as the number you assigned to `MATRIX_ROWS`, and likewise for `MATRIX_COL_PINS` and `MATRIX_COLS`. You do not have to specify `UNUSED_PINS`, but you can if you want to document what pins are open.
-
-Finally, you can specify the direction your diodes point. This can be `COL2ROW` or `ROW2COL`.
-
-```c
-#define DIODE_DIRECTION COL2ROW
-```
-
-#### Direct Pin Matrix
-To configure a keyboard where each switch is connected to a separate pin and ground instead of sharing row and column pins, use `DIRECT_PINS`. The mapping defines the pins of each switch in rows and columns, from left to right. Must conform to the sizes within `MATRIX_ROWS` and `MATRIX_COLS`, use `NO_PIN` to fill in blank spaces. Overrides the behaviour of `DIODE_DIRECTION`, `MATRIX_ROW_PINS` and `MATRIX_COL_PINS`.
-
-```c
-// #define MATRIX_ROW_PINS { D0, D5 }
-// #define MATRIX_COL_PINS { F1, F0, B0 }
-#define DIRECT_PINS { \
-    { F1, E6, B0, B2, B3 }, \
-    { F5, F0, B1, B7, D2 }, \
-    { F6, F7, C7, D5, D3 }, \
-    { B5, C6, B6, NO_PIN, NO_PIN } \
-}
-#define UNUSED_PINS
-
-/* COL2ROW, ROW2COL */
-//#define DIODE_DIRECTION
-```
-
-### Backlight Configuration
-
-QMK supports backlighting on most GPIO pins. A select few of these can be driven by the MCU in hardware. For more details see the [Backlight Documentation](feature_backlight.md).
-
-```c
-#define BACKLIGHT_PIN B7
-#define BACKLIGHT_LEVELS 3
-#define BACKLIGHT_BREATHING
-#define BREATHING_PERIOD 6
-```
-
-### Other Configuration Options
-
-There are a lot of features that can be configured or tuned in `config.h`. You should see the [Config Options](config_options.md) page for more details.
-
-## `rules.mk`
-
-You use the `rules.mk` file to tell QMK what files to build and what features to enable. If you are building around an atmega32u4 you can largely leave these defaults alone. If you are using another MCU you may have to tweak some parameters.
-
-### MCU Options
-
-These options tell the build system what CPU to build for. Be very careful if you change any of these settings, you can render your keyboard inoperable.
-
-```make
-MCU = atmega32u4
-F_CPU = 16000000
-ARCH = AVR8
-F_USB = $(F_CPU)
-OPT_DEFS += -DINTERRUPT_CONTROL_ENDPOINT
-```
-
-### Bootloaders
-
-The bootloader is a special section of your MCU that allows you to upgrade the code stored on the MCU. Think of it like a Rescue Partition for your keyboard. 
-
-#### Teensy Bootloader Example
-
-```make
-BOOTLOADER = halfkay
-```
-
-#### Atmel DFU Loader Example
-
-```make
-BOOTLOADER = atmel-dfu
-```
-
-#### Pro Micro Bootloader Example
-
-```make
-BOOTLOADER = caterina
-```
-
-### Build Options
-
-There are a number of features that can be turned on or off in `rules.mk`. See the [Config Options](config_options.md#feature-options) page for a detailed list and description.

+## Flashing STM32Duino Bootloader
+
+As mentioned above, *most* supported STM32 devices already possess a USB DFU bootloader which cannot be overwritten, however the ROM bootloader in the STM32F103 used on the Bluepill is not USB capable. In this case an ST-Link V2 dongle is required to upload the STM32Duino bootloader to the device. These can be readily purchased for relatively cheap on eBay and other places.
+
+This bootloader is a descendant of the Maple bootloader by Leaflabs, and is compatible with dfu-util.
+
+### Software
+
+To communicate with the ST-Link, you must install the following packages:
+
+* **macOS:** `brew install stlink openocd`
+* **Windows (MSYS2):** `pacman -S mingw-w64-x86_64-stlink mingw-w64-x86_64-openocd`
+* **Linux:** will vary by distribution, but will likely be `stlink` and `openocd` through your particular package manager
+
+Additionally, you may need to update the ST-Link's firmware with the [`STSW-LINK007`](https://www.st.com/en/development-tools/stsw-link007.html) application. Note you will be asked to provide your name and email address if you do not have an ST.com account (this does not create one).
+
+Finally, the bootloader binary itself can be downloaded from [here](https://github.com/rogerclarkmelbourne/STM32duino-bootloader/blob/master/bootloader_only_binaries/generic_boot20_pc13.bin).
+
+### Wiring
+
+Connect the four-pin header on the end of the Bluepill to the matching pins on the ST-Link (the pinout will usually be printed on the side):
+
+|ST-Link      |Bluepill|
+|-------------|--------|
+|`GND` (6)    |`GND`   |
+|`SWCLK` (2)  |`DCLK`  |
+|`SWDIO` (4)  |`DIO`   |
+|`3.3V` (8)   |`3.3`   |
+
+### Flashing
+
+Firstly, make sure both jumpers on the Bluepill are set to 0.
+
+Check that the ST-Link can talk to the Bluepill by running `st-info --probe`:
+
+```
+Found 1 stlink programmers
+  version:    V2J37S7
+  serial:     2C1219002B135937334D4E00
+  flash:      65536 (pagesize: 1024)
+  sram:       20480
+  chipid:     0x0410
+  descr:      F1xx Medium-density
+```
+
+If the reported `chipid` is `0x0410`, everything is working. If it is `0x0000`, check your wiring, and try swapping the `SWDIO` and `SWCLK` pins, as some ST-Link dongles may have incorrect pinouts.
+
+Next, run the following command:
+
+```
+st-flash --reset --format binary write <path-to-bootloader> 0x08000000
+```
+
+where `<path-to-bootloader>` is the path to the bootloader `.bin` file above. You can run this command from the directory you downloaded it to, so that you can simply pass in the filename.
+
+If all goes well, you should get output similar to the following:
+
+```
+st-flash 1.7.0

+
+Otherwise, if you receive an `Unknown memory region` error, run the following command to unlock the STM32F103:
+
+```
+openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c "init; reset halt; stm32f1x unlock 0; reset halt; exit"
+```
+
+Then re-plug the ST-Link and try again.
+
+After all of this, unplug the Bluepill from the ST-Link and connect it to USB. It should now be ready to flash using dfu-util, the QMK CLI or Toolbox.
