arrow_pad keyboard firmware

======================

|
|
## Keyboard Info
|
|
|
|
The ArrowPad is a wired conversion that can be made to any stand-alone keypad. It uses two main layers - a standard numpad, and a more advanced arrow cluster navigator.
|
|
|
|
The first 24-key ArrowPad was handwired, but the PCB was wired as listed below.
|
|
|
|
```
|
|
<Chip Ref Des> pin <Pin #>
|
|
<Keycap Name> (Silkscreen Name if different) - <Switch Pin #>

Note:
|
|
U2 pin 2 is the Num Lock LED and is active low.

The second ArrowPad was a conversion from a 21-key Genovation keypad. It used a 2 row x 11 column matrix.
|
|
|
|
```
|
|
#define KEYMAP( \
|
|
KM_ESC, KM_TAB, KM_BSL, KM_ARR, \
|
|
KM_NUM, KM_FSL, KM_AST, KM_MIN, \
|
|
KM___7, KM___8, KM___9, ___PLS, \
|
|
KM___4, KM___5, KM___6, KM_PLS, \
|
|
KM___1, KM___2, KM___3, ___ENT, \
|
|
KM___0, _____0, KM_DOT, KM_ENT \
|
|
) { \
|
|
{ KM_ESC, KM_TAB, KM_BSL, KM_ARR, KM___7, KM___8, KM___9, KM_PLS, KM___1, KM___2, KM___3, }, \
|
|
{ KM_NUM, KM_FSL, KM_AST, KM_MIN, KM___4, KM___5, KM___6, KM_ENT, KC_NO, KM___0, KM_DOT, }, \
|
|
}

## 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 keyboards/arrow_pad 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 default`.
|
|
|
|
### 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` in the keymaps folder, 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 a keymap like this:
|
|
|
|
```
|
|
$ make [default|pad_21|pad_24|<name>]
|
|
```
|
|
|
|
Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
