Original code from Hasu's TMK firmware. Ported to QMK by Coloneljesus.
A small device to connect between your USB keyboard and your PC that makes (almost) every keyboard fully programmable.
Original code from the [TMK firmware](https://github.com/tmk/tmk_keyboard/tree/master/converter/usb_usb). Ported to QMK by [Balz Guenat](https://github.com/BalzGuenat).
This port has been tested only on the Pro Micro variant described in the next section.
Make example for this keyboard (after setting up your build environment):
make converter-usb_usb-default
Hardware requirement
--------------------
There are two options.
See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
### TMK USB-USB Converter
You can buy a fully assembled converter from me here.
Getting the Hardware
--------------------
There are two options to get a converter: You can buy one from Hasu or build one yourself.
### Buy a Converter
You can buy a fully assembled converter from me here:
https://geekhack.org/index.php?topic=69169.0
### Arduino Leonardo + Circuit@Home USB Host Shield 2.0
### Build one yourself using Arduino Leonardo + Circuit@Home USB Host Shield 2.0
Buying Arduino Leonardo and USB Host Shield 2.0(from Circuit@home) will be better, you won't need even soldering iron.
Follow normal QMK build instructions to get a binary file. Flashing depends on you hardware.
Limitation
Limitations
----------
Only supports 'HID Boot protocol'.
Note that the converter can host only USB "boot protocol" keyboard(6KRO), not NKRO, it is possible to support NKRO keyboard but you will need to write HID report parser for that. Every NKRO keyboard can have different HID report and it is difficult to support all kind of NKRO keyboards in the market.
Keymap editor
-------------
You can editor keymap and download firmware with web brwoser.
