# NIBBLE
![NIBBLE](https://nullbits.co/static/img/nibble1.jpg)
A unique, tweakable 65% keyboard kit built by nullbits. [More info at nullbits.co](https://nullbits.co/nibble/)
* Keyboard Maintainer: [Jay Greco](https://github.com/jaygreco)
* Hardware Supported: NIBBLE Rev1, Pro Micro comaptible MCUs.
* Hardware Availability: [nullbits.co](https://nullbits.co/)
Note: If you are seeing issues with MacOS and keyboard hangs after sleep, make sure `NO_USB_STARTUP_CHECK = yes` is set in your rules.mk.
Adds experimental "Remote Keyboard" functionality, which forwards keystrokes from an external macropad, keyboard, or numpad over UART/TRRS, removing the need for an additional USB connection.
Make example for this keyboard (after setting up your build environment):
make nullbitsco/nibble:default
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

/*
Remote keyboard is an experimental feature that allows for connecting another
keyboard, macropad, numpad, or accessory without requiring an additional USB connection.
The "remote keyboard" forwards its keystrokes using UART serial over TRRS. Dynamic VUSB
detect allows the keyboard automatically switch to host or remote mode depending on
which is connected to the USB port.
Possible functionality includes the ability to send data from the host to the remote using
a reverse link, allowing for LED sync, configuration, and more data sharing between devices.
This will require a new communication protocol, as the current one is limited.
