+# ChibiOS Upgrade Procedure
+
+ChibiOS and ChibiOS-Contrib need to be updated in tandem -- the latter has a branch tied to the ChibiOS version in use and should not be mixed with different versions.
+
+## Getting ChibiOS
+
+* `svn` Initialisation:
+    * Only needed to be done once
+    * You might need to separately install `git-svn` package in your OS's package manager
+    * `git svn init --stdlayout --prefix='svn/' http://svn.osdn.net/svnroot/chibios/`
+    * `git remote add qmk git@github.com:qmk/ChibiOS.git`
+* Updating:
+    * `git svn fetch`
+    * First time around this will take several hours
+    * Subsequent updates will be incremental only
+* Tagging example (work out which version first!):
+    * `git tag -a ver20.3.3 -m ver20.3.3 svn/tags/ver20.3.3`
+    * `git push qmk ver20.3.3`
+    * `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN svn/tags/ver20.3.3`
+    * `git push qmk breaking_YYYY_qN`
+
+## Getting ChibiOS-Contrib
+
+* `git` Initialisation:
+    * `git clone git@github.com:qmk/ChibiOS-Contrib`
+    * `git remote add upstream https://github.com/ChibiOS/ChibiOS-Contrib`
+    * `git checkout -b chibios-20.3.x upstream/chibios-20.3.x`
+* Updating:
+    * `git fetch --all --tags --prune`
+    * `git checkout chibios-20.3.x`
+    * `git pull --ff-only`
+    * `git push origin chibios-20.3.x`
+    * `git tag -a breaking_YYYY_qN -m breaking_YYYY_qN chibios-20.3.x`
+    * `git push origin breaking_YYYY_qN`
+
+## Updating submodules
+
+* Update the submodules
+    * `cd $QMK_FIRMWARE`
+    * `git checkout develop`
+    * `git pull --ff-only`
+    * `git checkout -b chibios-version-bump`
+    * `cd lib/chibios`
+    * `git fetch --all --tags --prune`
+    * `git checkout breaking_YYYY_qN`
+    * `cd ../chibios-contrib`
+    * `git fetch --all --tags --prune`
+    * `git checkout breaking_YYYY_qN`
+* Build everything
+    * `cd $QMK_FIRMWARE`
+    * `qmk multibuild -j4`
+    * Make sure there are no errors
+* Push to the repo
+    * `git commit -am 'Update ChibiOS to XXXXXXXXX'`
+    * `git push --set-upstream origin chibios-version-bump`
+* Make a PR to qmk_firmware with the new branch

+
+### Custom data sync between sides :id=custom-data-sync
+
+QMK's split transport allows for arbitrary data transactions at both the keyboard and user levels. This is modelled on a remote procedure call, with the master invoking a function on the slave side, with the ability to send data from master to slave, process it slave side, and send data back from slave to master.
+
+To leverage this, a keyboard or user/keymap can define a comma-separated list of _transaction IDs_:
+
+```c
+// for keyboard-level data sync:
+#define SPLIT_TRANSACTION_IDS_KB KEYBOARD_SYNC_A, KEYBOARD_SYNC_B
+// or, for user:
+#define SPLIT_TRANSACTION_IDS_USER USER_SYNC_A, USER_SYNC_B, USER_SYNC_C
+```
+
+These _transaction IDs_ then need a slave-side handler function to be registered with the split transport, for example:
+
+```c
+typedef struct _master_to_slave_t {
+    int m2s_data;
+} master_to_slave_t;
+
+typedef struct _slave_to_master_t {
+    int s2m_data;
+} slave_to_master_t;
+
+void user_sync_a_slave_handler(uint8_t in_buflen, const void* in_data, uint8_t out_buflen, void* out_data) {
+    const master_to_slave_t *m2s = (const master_to_slave_t*)in_data;
+    slave_to_master_t *s2m = (slave_to_master_t*)out_data;
+    s2m->s2m_data = m2s->m2s_data + 5; // whatever comes in, add 5 so it can be sent back
+}
+
+void keyboard_post_init_user(void) {
+    transaction_register_rpc(USER_SYNC_A, user_sync_a_slave_handler);
+}
+```
+
+The master side can then invoke the slave-side handler - for normal keyboard functionality to be minimally affected, any keyboard- or user-level code attempting to sync data should be throttled:
+
+```c
+void housekeeping_task_user(void) {
+    if (is_keyboard_master()) {
+        // Interact with slave every 500ms
+        static uint32_t last_sync = 0;
+        if (timer_elapsed32(last_sync) > 500) {
+            master_to_slave_t m2s = {6};
+            slave_to_master_t s2m = {0};
+            if(transaction_rpc_exec(USER_SYNC_A, sizeof(m2s), &m2s, sizeof(s2m), &s2m)) {
+                last_sync = timer_read32();
+                dprintf("Slave value: %d\n", s2m.s2m_data); // this will now be 11, as the slave adds 5
+            } else {
+                dprint("Slave sync failed!\n");
+            }
+        }
+    }
+}
+```
+
+!> It is recommended that any data sync between halves happens during the master side's _housekeeping task_. This ensures timely retries should failures occur.
+
+If only one-way data transfer is needed, helper methods are provided:
+
+```c
+bool transaction_rpc_exec(int8_t transaction_id, uint8_t initiator2target_buffer_size, const void *initiator2target_buffer, uint8_t target2initiator_buffer_size, void *target2initiator_buffer);
+bool transaction_rpc_send(int8_t transaction_id, uint8_t initiator2target_buffer_size, const void *initiator2target_buffer);
+bool transaction_rpc_recv(int8_t transaction_id, uint8_t target2initiator_buffer_size, void *target2initiator_buffer);
+```
+
+By default, the inbound and outbound data is limited to a maximum of 32 bytes each. The sizes can be altered if required:
+
+```c
+// Master to slave:
+#define RPC_M2S_BUFFER_SIZE 48
+// Slave to master:
+#define RPC_S2M_BUFFER_SIZE 48

+## Usage
+
+To enable the feature, there are three steps. First, when compiling your keyboard, you'll need to add the following to your `rules.mk`:
+
+```make
+ST7565_ENABLE = yes
+```
+
+Then in your `keymap.c` file, implement the ST7565 task call. This example assumes your keymap has three layers named `_QWERTY`, `_FN` and `_ADJ`:
+
+```c
+#ifdef ST7565_ENABLE

+    // Host Keyboard Layer Status
+    st7565_write_P(PSTR("Layer: "), false);
+
+    switch (get_highest_layer(layer_state)) {
+        case _QWERTY:
+            st7565_write_P(PSTR("Default\n"), false);
+            break;
+        case _FN:

+
+## Buffer Read Example
+For some purposes, you may need to read the current state of the display buffer. The `st7565_read_raw` function can be used to safely read bytes from the buffer.
+
+In this example, calling `fade_display` in the `st7565_task_user` function will slowly fade away whatever is on the screen by turning random pixels off over time.
+```c
+//Setup some mask which can be or'd with bytes to turn off pixels
+const uint8_t single_bit_masks[8] = {127, 191, 223, 239, 247, 251, 253, 254};
+
+static void fade_display(void) {
+    //Define the reader structure
+    display_buffer_reader_t reader;
+    uint8_t buff_char;
+    if (random() % 30 == 0) {
+        srand(timer_read());
+        // Fetch a pointer for the buffer byte at index 0. The return structure
+        // will have the pointer and the number of bytes remaining from this
+        // index position if we want to perform a sequential read by
+        // incrementing the buffer pointer
+        reader = st7565_read_raw(0);
+        //Loop over the remaining buffer and erase pixels as we go
+        for (uint16_t i = 0; i < reader.remaining_element_count; i++) {
+            //Get the actual byte in the buffer by dereferencing the pointer
+            buff_char = *reader.current_element;
+            if (buff_char != 0) {
+                st7565_write_raw_byte(buff_char & single_bit_masks[rand() % 8], i);
+            }
+            //increment the pointer to fetch a new byte during the next loop
+            reader.current_element++;
+        }
+    }
+}
+```
+
+## Other Examples
+
+In split keyboards, it is very common to have two displays that each render different content and are oriented or flipped differently. You can do this by switching which content to render by using the return value from `is_keyboard_master()` or `is_keyboard_left()` found in `split_util.h`, e.g:
+
+```c
+#ifdef ST7565_ENABLE
+display_rotation_t st7565_init_user(display_rotation_t rotation) {
+    if (!is_keyboard_master()) {
+        return DISPLAY_ROTATION_180;  // flips the display 180 degrees if offhand
+    }
+
+    return rotation;
+}
+
+void st7565_task_user(void) {
+    if (is_keyboard_master()) {
+        render_status();  // Renders the current keyboard state (layer, lock, caps, scroll, etc)
+    } else {
+        render_logo();  // Renders a static logo
+    }
+}
+#endif
+```

 ## FAQ

 ### なぜ Windows/macOS 上で書き込めないのですか？

 Windows と macOS では、実行するために [Docker Machine](http://gw.tnode.com/docker/docker-machine-with-usb-support-on-windows-macos/) が必要です。これはセットアップが面倒なので、お勧めではありません: 代わりに [QMK Toolbox](https://github.com/qmk/qmk_toolbox) を使ってください。

 `make` コマンドの完全な構文は `<keyboard_folder>:<keymap>:<target>` です:
@@ -19,16 +19,32 @@
 `<target>` は以下を意味します
 * target が指定されない場合は、以下の `all` と同じです
 * `all` は指定されたキーボード/リビジョン/キーマップの可能な全ての組み合わせのコンパイルを行います。例えば、`make planck/rev4:default` は1つの .hex を生成しますが、`make planck/rev4:all` は planck で利用可能な全てのキーマップについて hex を生成します。
-* `flash`、`dfu`、`teensy`、`avrdude`、`dfu-util` または `bootloadHID` はファームウェアをコンパイルし、キーボードにアップロードします。コンパイルが失敗すると、何もアップロードされません。使用するプログラマはキーボードに依存します。ほとんどのキーボードでは `dfu` ですが、ChibiOS キーボードについては `dfu-util` 、標準的な Teensy については `teensy` を使います。キーボードに使うコマンドを見つけるには、キーボード固有の readme をチェックしてください。
-* **注意**: 一部のオペレーティングシステムではこれらのコマンドが機能するためには root アクセスが必要です。その場合、例えば `sudo make planck/rev4:default:flash` を実行する必要があります。

+  利用可能なブートローダの詳細は[ファームウェアの書き込み](ja/flashing.md)ガイドを参照してください。
+  * **Note**:  一部のオペレーティングシステムでは、これらのコマンドが機能するためには特権アクセスが必要です。これは、root アクセスなしでこれらにアクセスするために [`udev ルール`](ja/faq_build.md#linux-udev-rules) を設定するか、あるいは root アクセスでコマンドを実行する (`sudo make planck/rev4:default:flash`) 必要があるかもしれないことを意味します。
 * `clean` は、全てをゼロからビルドするためにビルド出力フォルダを掃除します。説明できない問題がある場合は、通常のコンパイルの前にこれを実行してください。
+* `distclean` は、.hex ファイルと .bin ファイルを削除します。
+
+次のターゲットは開発者向けです:
+
+* `show_path` ソースとオブジェクトファイルのパスを表示します。
+* `dump_vars` makefile 変数をダンプします。
+* `objs-size` 個々のオブジェクトファイルのサイズを表示します。
+* `show_build_options` 'rules.mk' のオプションセットを表示します。
+* `check-md5` 生成されたバイナリファイルの md5 チェックサムを表示します。

 make コマンドの最後、つまり target の後に追加のオプションを追加することもできます

 * `make COLOR=false` - カラー出力をオフ
 * `make SILENT=true` - エラー/警告以外の出力をオフ
 * `make VERBOSE=true` - 全ての gcc のものを出力 (デバッグする必要が無い限り面白くありません)
-* `make EXTRAFLAGS=-E` - コンパイルせずにコードを前処理 (#define コマンドをデバッグしようとする場合に便利)
+* `make VERBOSE_LD_CMD=yes` - -v オプションを指定して ld コマンドを実行します。
+* `make VERBOSE_AS_CMD=yes` - -v オプションを指定して as コマンドを実行します。
+* `make VERBOSE_C_CMD=<c_source_file>` - 指定された C ソースファイルをコンパイルするときに -v オプションを追加します。
+* `make DUMP_C_MACROS=<c_source_file>` - 指定された C ソースファイルをコンパイルするときにプリプロセッサマクロをダンプします。
+* `make DUMP_C_MACROS=<c_source_file> > <logfile>` - 指定された C ソースファイルをコンパイルするときにプリプロセッサマクロを `<logfile>` にダンプします。
+* `make VERBOSE_C_INCLUDE=<c_source_file>` - 指定された C ソースファイルをコンパイルするときにインクルードされるファイル名をダンプします。
+* `make VERBOSE_C_INCLUDE=<c_source_file> 2> <logfile>` - 指定された C ソースファイルをコンパイルするときにインクルードされるファイル名を `<logfile>` にダンプします。

 make コマンド自体にもいくつかの追加オプションがあります。詳細は `make --help` を入力してください。最も有用なのはおそらく `-jx` です。これは複数の CPU を使ってコンパイルしたいことを指定し、`x` は使用したい CPU の数を表します。設定すると、特に多くのキーボード/キーマップをコンパイルしている場合は、コンパイル時間を大幅に短縮することができます。通常は、コンパイル中に他の作業を行うための余裕をもたせるために、持っている CPU の数より1つ少ない値に設定します。全てのオペレーティングシステムと make バージョンがオプションをサポートしているわけではないことに注意してください。

+# CONSTELLATION REV1
+
+A gasket 65% keyboard by [aeboards](https://aeboards.com/)
+
+* Keyboard Maintainer: [Xelus22](https://github.com/Xelus22)
+* Hardware Supported: CONSTELLATION
+* Hardware Availability: Custom keyboard group buys
+
+Make example for this keyboard (after setting up your build environment):
+
+    make aeboards/constellation/rev1:default
+
+Reset your keyboard in 3 ways:
+<ol>
+<li>Software reset on Fn + Backspace</li>
+<li>Bootmagic reset: hold down the top left key (usually escape) and plugin the keyboard</li>
+<li>Physical reset: on the back of the PCB, there is a ISP header which you should short the RST and GND together</li>
+</ol>
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

+# CONSTELLATION REV2
+
+A gasket 65% keyboard by [aeboards](https://aeboards.com/)
+
+* Keyboard Maintainer: [Xelus22](https://github.com/Xelus22)
+* Hardware Supported: CONSTELLATION
+* Hardware Availability: Custom keyboard group buys
+
+Make example for this keyboard (after setting up your build environment):
+
+    make aeboards/constellation/rev2:default
+
+Reset your keyboard in 3 ways:
+<ol>
+<li>Software reset on Fn + Backspace</li>
+<li>Bootmagic reset: hold down the top left key (usually escape) and plugin the keyboard</li>
+<li>Physical reset button: on the back of the PCB, there are 2 open pins which you can short, labelled RESET</li>
+</ol>
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
