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.

The second ArrowPad was a conversion from a 21-key Genovation keypad. It used a 2 row x 11 column matrix.

Quantum MK Firmware

For the full Quantum feature list, see the parent 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 handwired/arrow_pad: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 handwired/arrow_pad:[default|pad_21|pad_24|<name>]

Keymaps follow the format <name>.c and are stored in the keymaps folder.
