[WIP] AudioMacro18 - Macropad with 18 macro keys and 5 encoders

Disclaimer:
This project is not actively maintained and was created for personal use, hence no official support of any kind is provided!

Goals:  

• Control audio on a application or device basis (Deej)
• Easily create keymaps (QMK)
• Have an interface to dynamically reassign the keymap (VIA/VIAL)
• Remap encoder functions dynamically in an interface (VIAL)

Design:

For the design I've created a fork of Deej that supports communication to it's API over the HID interface, instead of over a serial port.
Using this fork I was able to create some code in my QMK keymap to send volume up/down events over the HID interface to Deej.

Software:

Deej/QMK fork: https://github.com/Pieterv24/deej/tree/qmk

QMK firmware: https://github.com/Pieterv24/vial-qmk/tree/keyboards/keyboards/handwired/pieterv24/audio_macro16

QMK deej firmware (some documentation is available here): https://github.com/Pieterv24/vial-qmk/tree/keyboards/keyboards/handwired/pieterv24/audio_macro16/keymaps/deej

Hardware:

• 18x cherry mx style switches
• 18x diode (for grid)
• 1x arduino pro micro - atmel 32u4 (Make sure the microcontroller supports HID)
• 5x rotary encoder
• 4x m2 screws 
• 4x m2 heat set inserts

Limitations:

• Currently the deej fork required for the audio functionality only works on Linux (tested on arch linux)
• This project is not being actively maintained
