retro_refit keyboard firmware
|
||||
======================
|
||||
|
||||
## Quantum MK Firmware
|
||||
|
||||
For the full Quantum feature list, see [the parent README.md](/README.md).
|
||||
|
||||
## Building
|
||||
|
||||
Download or clone the whole firmware and navigate to the keyboard/retro_refit folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file.
|
||||
|
||||
Depending on which keymap you would like to use, you will have to compile slightly differently.
|
||||
|
||||
### Default
|
||||
To build with the default keymap, simply run `make`.
|
||||
|
||||
### Other Keymaps
|
||||
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 `<name>.c` and see keymap document (you can find in top README.md) and existent keymap files.
|
||||
|
||||
To build the firmware binary hex file with a keymap just do `make` with `KEYMAP` option like:
|
||||
```
|
||||
$ make KEYMAP=[default|jack|<name>]
|
||||
```
|
||||
Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
