Use <kbd>TAB</kbd>+<kbd>X</kbd> to cycle through the following LED modes:
- solid
- breathing
- random
- rain
- reactive
- poptang
- off

# ut47
![ut47](https://i.imgur.com/ZDKZQaj.jpg)
Somewhere between ortholinear and standard offset. Created to have all the same functions on a Planck in a keyboard but with a more conventional keyboard row stagger.
Keyboard Maintainer: [filoxo](https://github.com/filoxo), [network_operations]
Hardware Supported: [PCB design](http://www.40percent.club/2016/10/gnap-20-plateless.html), Arduino Pro Micro
Hardware Availability: [How to order](http://www.40percent.club/2017/03/ordering-pcb.html)
### Instructions
To flash the UT47 without LEDs (single controller), run:
make ut47:default
To enable the UT47 LEDs (dual controller), run this for the main controller:
make ut47:default LED_ENABLE=yes
Or you can add `LED_ENABLE = yes` to *rules.mk*
And then flash [LED_controls.ino](LED_controls.ino) to the second controller using [Arduino IDE](https://www.arduino.cc/en/Main/Software) or similar. NOTE: Arduino IDE will require importing additional libraries to compile.
<small>The reason this is an "opt-in" feature is to prevent sending serial communication over the pin, in case it ends up being used for something else (like RGB underglow).</small>
### Layout
Go to the [default layout README](keymaps/default/readme.md) for more information.
### Additional info
Credit: Forked from [di0ib TMK version](https://github.com/di0ib/tmk_keyboard/tree/master/keyboard/gnap)
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.
