# Planck Firmware Guide
|
|
|
|
## Setting up the environment
|
|
|
|
### Windows
|
|
1. Install [MHV AVR Tools](https://infernoembedded.com/sites/default/files/project/MHV_AVR_Tools_20131101.exe). Disable smatch, but **be sure to leave the option to add the tools to the PATH checked**.
|
|
2. Install [MinGW](https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download). During installation, uncheck the option to install a graphical user interface. **DO NOT change the default installation folder.** The scripts depend on the default location.
|
|
3. Clone this repository. [This link will download it as a zip file, which you'll need to extract.](https://github.com/jackhumbert/qmk_firmware/archive/master.zip) Open the extracted folder in Windows Explorer.
|
|
4. Right-click on the 1-setup-path-win batch script, select "Run as administrator", and accept the User Account Control prompt. Press the spacebar to dismiss the success message in the command prompt that pops up.
|
|
5. Right-click on the 2-setup-environment-win batch script, select "Run as administrator", and accept the User Account Control prompt. This part may take a couple of minutes, and you'll need to approve a driver installation, but once it finishes, your environment is complete!
|
|
|
|
|
|
### Mac
|
|
|
|
If you're using homebrew, you can use the following commands:
|
|
|
|
brew tap osx-cross/avr
|
|
brew install avr-libc
|
|
brew install dfu-programmer
|
|
|
|
Otherwise, these instructions will work:
|
|
|
|
1. Install Xcode from the App Store.
|
|
2. Install the Command Line Tools from `Xcode->Preferences->Downloads`.
|
|
3. Install [DFU-Programmer][dfu-prog].
|
|
|
|
### Linux
|
|
1. Install AVR GCC with your favorite package manager.
|
|
2. Install [DFU-Programmer][dfu-prog].
|
|
|
|
Note that, since it will be directly accessing USB hardware, the
|
|
`dfu-programmer` program needs to be run as root.
|
|
|
|
## Verify Your Installation
|
|
1. Clone the following repository: https://github.com/jackhumbert/qmk_firmware
|
|
2. Open a Terminal and `cd` into `qmk_firmware/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 KEYMAP=<keymap>`: compile with the extended keymap file `extended_keymaps/extended_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.
|
|
|
|
## Troubleshooting
|
|
If you see something like this
|
|
|
|
0 [main] sh 13384 sync_with_child: child 9716(0x178) died before initialization with status code 0xC0000142
|
|
440 [main] sh 13384 sync_with_child: *** child state waiting for longjmp
|
|
/usr/bin/sh: fork: Resource temporarily unavailable
|
|
|
|
after running 'make' on Windows than you are encountering a very popular issue with WinAVR on Windows 8.1 and 10.
|
|
You can easily fix this problem by replacing msys-1.0.dll in WinAVR/utils/bin with [this one](http://www.madwizard.org/download/electronics/msys-1.0-vista64.zip).
|
|
Restart your system and everything should work fine!
|
|
|
|
|
|
If you see this
|
|
|
|
dfu-programmer atmega32u4 erase
|
|
process_begin: CreateProcess(NULL, dfu-programmer atmega32u4 erase, ...) failed.
|
|
make (e=2): The system cannot find the file specified.
|
|
make: *** [dfu] Error 2
|
|
|
|
when trying to 'make dfu' on Windows you need to copy the dfu-programmer.exe to qmk_firmware/keyboard/planck.
|
|
|
|
|
|
## Quantum MK Firmware
|
|
|
|
### Keymap
|
|
|
|
Unlike the other keymaps, prefixing the keycodes with `KC_` is required. A full list of the keycodes is available [here](https://github.com/jackhumbert/qmk_firmware/blob/master/tmk_core/doc/keycode.txt). For the keycodes available only in the extended keymap, see this [header file](https://github.com/jackhumbert/qmk_firmware/blob/master/quantum/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 `keymaps/keymap_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.
