+# Planck Firmware Guide
+
+## Setting up the environment
+
+### Windows
+1. Install [WinAVR Tools](http://sourceforge.net/projects/winavr/) for AVR GCC compiler.
+2. Install [DFU-Programmer][dfu-prog] (the -win one).
+3. Start DFU bootloader on the chip first time you will see 'Found New Hardware Wizard' to install driver. If you install device driver properly you can find chip name like 'ATmega32U4' under 'LibUSB-Win32 Devices' tree on 'Device Manager'. If not you will need to update its driver on 'Device Manager' to the `dfu-programmer` driver.
+
+### Mac
+1. Install [CrossPack](http://www.obdev.at/products/crosspack/index.html) or install Xcode from the App Store and install the Command Line Tools from `Xcode->Preferences->Downloads`.
+2. Install [DFU-Programmer][dfu-prog].
+
+### Linux
+1. Install AVR GCC with your favorite package manager.
+2. Install [DFU-Programmer][dfu-prog].
+
+##Verify Your Installation
+1. Clone the following repository: https://github.com/jackhumbert/tmk_keyboard
+2. Open a Terminal and `cd` into `tmk_keyboard/keyboard/planck`
+3. Run `make`. This should output a lot of information about the build process.
+
+## Using the built-in functions
+
+Here is a list of some of the functions available from the command line:
+
+* `make clean`: clean the environment - may be required in-between builds
+* `make`: compile the code
+* `make COMMON=true`: compile with the common (non-extended) keymap
+* `make MATRIX=<matrix_file>`: compile with the referenced matrix file. Default if unspecified is `matrix_pcb.c`. For handwired boards, use `matrix_handwired.c`.
+* `make KEYMAP=<keymap>`: compile with the extended keymap file `extended_keymaps/extended_keymap_<keymap>.c`
+* `make COMMON=true KEYMAP=<keymap>`: compile with the common keymap file `common_keymaps/keymap_<keymap>.c`
+* `make dfu`: build and flash the layout to the PCB
+* `make dfu-force`: build and force-flash the layout to the PCB (may be require for first flash)
+
+Generally, the instructions to flash the PCB are as follows:
+
+1. Make changes to the appropriate keymap file
+2. Save the file
+3. `make clean`
+4. Press the reset button on the PCB/press the key with the `RESET` keycode
+5. `make <arguments> dfu` - use the necessary `KEYMAP=<keymap>` and/or `COMMON=true` arguments here.
+
+## Extended keymap
+
+### Keymap
+
+Unlike the common keymap, prefixing the keycodes with `KC_` is required. A full list of the keycodes is available [here](https://github.com/jackhumbert/tmk_keyboard/blob/master/doc/keycode.txt). For the keycodes available only in the extended keymap, see this [header file](https://github.com/jackhumbert/tmk_keyboard/blob/master/keyboard/planck/extended_keymap_common.h).
+
+You can use modifiers with keycodes like this:
+
+    LCTL(KC_C)
+    
+Which will generate Ctrl+c. These are daisy-chainable, meaning you can do things like:
+
+    LCTL(LALT(KC_C))
+    
+That will generate Ctrl+Alt+c. The entire list of these functions is here:
+
+* `LCTL()`: Left control
+* `LSFT()` / `S()`: Left shift
+* `LALT()`: Left alt/opt
+* `LGUI()`: Left win/cmd
+* `RCTL()`: Right control
+* `RSFT()`: Right shift
+* `RALT()`: Right alt/opt
+* `RGUI()`: Right win/cmd
+
+`S(KC_1)`-like entries are useful in writing keymaps for the Planck.
+
+### Other keycodes
+
+A number of other keycodes have been added that you may find useful:
+
+* `CM_<key>`: the Colemak equivalent of a key (in place of `KC_<key>`), when using Colemak in software (`CM_O` generates `KC_SCLN`)
+* `RESET`: jump to bootloader for flashing (same as press the reset button)
+* `BL_STEP`: step through the backlight brightnesses
+* `BL_<0-15>`: set backlight brightness to 0-15
+* `BL_DEC`: lower the backlight brightness
+* `BL_INC`: raise the backlight brightness
+* `BL_TOGG`: toggle the backlight on/off
+
+### Function layers
+
+The extended keymap extends the number of function layers from 32 to the near-infinite value of 256. Rather than using `FN<num>` notation (still available, but limited to `FN0`-`FN31`), you can use the `FUNC(<num>)` notation. `F(<num>)` is a shortcut for this.
+
+The function actions are unchanged, and you can see the full list of them [here](https://github.com/jackhumbert/tmk_keyboard/blob/master/common/action_code.h). They are explained in detail [here](https://github.com/jackhumbert/tmk_keyboard/blob/master/doc/keymap.md#2-action).
+
+### Macros
+
+Macros have been setup in the `extended_keymaps/extended_keymaps_default.c` file so that you can use `M(<num>)` to access a macro in the `action_get_macro` section on your keymap. The switch/case structure you see here is required, and is setup for `M(0)` - you'll need to copy and paste the code to look like this (e.g. to support `M(3)`):
+
+    switch(id) {
+      case 0:
+        return MACRODOWN(TYPE(KC_A), END);
+        break;
+      case 1:
+        return MACRODOWN(TYPE(KC_B), END);
+        break;
+      case 2:
+        return MACRODOWN(TYPE(KC_C), END);
+        break;
+      case 3:
+        return MACRODOWN(TYPE(KC_D), END);
+        break;
+    } 
+    return MACRO_NONE;
+
+`MACRODOWN()` is a shortcut for `(record->event.pressed ? MACRO(__VA_ARGS__) : MACRO_NONE)` which tells the macro to execute when the key is pressed. Without this, the macro will be executed on both the down and up stroke.

+Planck keyboard firmware
+======================
+DIY/Assembled compact ortholinear 40% keyboard by [Ortholinear Keyboards](http://ortholinearkeyboards.com).
+
+## Extended Keymap
+If you include extended_keymap_common.h instead of keymap_common.h at the top of your file, you'll have access to a bunch of goodies:
+
+- Use `LSFT()`, `LCTL()`, et. al. (listed in extended_keymap_common.h) as modifiers for keys (daisy-chain-able)
+- Use `FUNC(1)` instead of `FN1` (etc.) to access the function layers beyond the 32 function layer limit
+- Use `CM_F` instead of `KC_F` to get the ColeMak equivilent for shortcuts (maps backwards)
+- Use `MACRODOWN()` instead of `MACRO()` to easily make a keydown macro (`CM_*` works here too)
+
+### Some notes on usage:
+
+- The `KEYMAP()` macro is unable to be used due to the bitwise modifications that take place - refer to extended_keymap_jack.c to see how to set things up with the `KC_` prefix
+- Keep an eye on the Makefile - this needs to include the correct files to work
+- Don't forget to use `const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {` instead of the 8bit equivilent
+
+## Build
+
+Follow [this guide](http://deskthority.net/workshop-f7/how-to-build-your-very-own-keyboard-firmware-t7177.html) to setup your development environment before anything else. Abbreviated instructions are provide at the [bottom of this document](https://github.com/rswiernik/tmk_keyboard/tree/rswiernik_dev/keyboard/planck#environment-setup)
+
+Download the whole firmware [here](https://github.com/jackhumbert/tmk_keyboard/archive/master.zip) and navigate to the keyboard/planck folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex that you can load with the Teensy app onto your Planck (once you've hit reset/shorted GND & RST). 
+
+Depending on which keymap you would like to use, you will have to compile slightly differently.
+
+####Default
+To build with the default keymap, simply move to the tmk\_keyboard/keyboard/planck/ and run `make` as follows:
+```
+$ make
+```
+
+## Keymap
+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `keymap_<name>.c` and see keymap document (you can find in top README.md) and existent keymap files.
+    
+####**Extended Keymaps**
+
+To build the firmware binary hex file with an extended keymap just do `make` with `KEYMAP` option like:
+```
+$ make KEYMAP=[common|jack|<name>]
+```
+_The only applicable keymaps will work with this option._ Extended keymaps follow the format **__extended\_keymap\_\<name\>.c__**
+
+####**Common Keymaps**
+
+Building with a common keymap is as simple as adding the COMMON option. Note that only 
+```
+$ make KEYMAP=[common|jack|<name>] COMMON=true
+```
+_The only applicable keymaps will work with this option._ Common keymaps follow the format **__keymap\_\<name\>.c__**
+
+## Notable TMK forks (which some of the keymap files are from)
+- [Shane's Fork](https://github.com/shanecelis/tmk_keyboard/tree/master/keyboard/planck)
+- [Pierre's Fork](https://github.com/pcarrier/tmk_keyboard/blob/pcarrier/planck/keyboard/gh60/keymap_planck.c)
+- [Nathan's Fork](https://github.com/nathanrosspowell/tmk_keyboard/tree/planck-jack/keyboard/planck)
+- [Matthew's Fork](https://github.com/pepers/tmk_keyboard/tree/master/keyboard/planck_grid)
