+# 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

+## 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
+void st7565_task_user(void) {
+    // 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:
+            st7565_write_P(PSTR("FN\n"), false);
+            break;
+        case _ADJ:
+            st7565_write_P(PSTR("ADJ\n"), false);
+            break;
+        default:
+            // Or use the write_ln shortcut over adding '\n' to the end of your string
+            st7565_write_ln_P(PSTR("Undefined"), false);
+    }
+    // Host Keyboard LED Status
+    led_t led_state = host_keyboard_led_state();
+    st7565_write_P(led_state.num_lock ? PSTR("NUM ") : PSTR("    "), false);
+    st7565_write_P(led_state.caps_lock ? PSTR("CAP ") : PSTR("    "), false);
+    st7565_write_P(led_state.scroll_lock ? PSTR("SCR ") : PSTR("    "), false);
+}
+#endif
+```
+## Logo Example
+In the default font, certain ranges of characters are reserved for a QMK logo. To render this logo to the screen, use the following code example:
+```c
+static void render_logo(void) {
+    static const char PROGMEM qmk_logo[] = {
+        0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x86, 0x87, 0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E, 0x8F, 0x90, 0x91, 0x92, 0x93, 0x94,
+        0xA0, 0xA1, 0xA2, 0xA3, 0xA4, 0xA5, 0xA6, 0xA7, 0xA8, 0xA9, 0xAA, 0xAB, 0xAC, 0xAD, 0xAE, 0xAF, 0xB0, 0xB1, 0xB2, 0xB3, 0xB4,
+        0xC0, 0xC1, 0xC2, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8, 0xC9, 0xCA, 0xCB, 0xCC, 0xCD, 0xCE, 0xCF, 0xD0, 0xD1, 0xD2, 0xD3, 0xD4, 0x00
+    };
+    st7565_write_P(qmk_logo, false);
+}
+```
+## 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
+```

+Layout in [Keyboard Layout Editor](http://www.keyboard-layout-editor.com/#/gists/76efb423a46cbbea75465cb468eef7ff) and [adjust layer](http://www.keyboard-layout-editor.com/#/gists/4bcf66f922cfd54da20ba04905d56bd4)
+Features:
+- Symmetric modifiers (CMD/Super, Alt/Opt, Ctrl, Shift)
+- Various modes, can be switched (using Adjust layer and the selected one is stored in EEPROM.
+- Modes for Qwerty and Colemak support
+- Modes for Mac vs Linux/Win support -> different order of modifiers and different action shortcuts on the "UPPER" layer (the red one in the image). Designed to simplify transtions when switching between operating systems often.
+- The OLED on master half shows selected mode and caps lock state and is rotated.
+- Left encoder controls volume up/down/mute. Right encoder PGUP/PGDOWN.

+# Sofle Keyboard
+![SofleKeyboard version 1](https://raw.githubusercontent.com/josefadamcik/SofleKeyboard/master/Images/IMG_20200126_114622.jpg)
+Sofle is 6×4+5 keys column-staggered split keyboard. Based on Lily58, Corne and Helix keyboards.
+More details about the keyboard on my blog: [Let me introduce you SofleKeyboard - a split keyboard based on Lily58 and Crkbd](https://josef-adamcik.cz/electronics/let-me-introduce-you-sofle-keyboard-split-keyboard-based-on-lily58.html)
+The current (temporary) build guide and a build log is available here: [SofleKeyboard build log/guide](https://josef-adamcik.cz/electronics/soflekeyboard-build-log-and-build-guide.html)
+* Keyboard Maintainer: [Josef Adamcik](https://josef-adamcik.cz) [Twitter:@josefadamcik](https://twitter.com/josefadamcik)  
+* Hardware Supported: SofleKeyboard PCB, ProMicro  
+* Hardware Availability: [PCB & Case Data](https://github.com/josefadamcik/SofleKeyboard)
+Make example for this keyboard (after setting up your build environment):
+    make sofle:default
+Flashing example for this keyboard:
+    make sofle:default:flash
+Press reset button on he keyboard when asked.
+Disconnect the first half, connect the second one and repeat the process.
+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).
