BigKNOBv2

What Is This?

This project includes:

1. QMK files for BigKNOBv2 macropad controller with RGB LED key switches.
2. C# source for application enabling bidirectional communication between BigKNOBv2 and the host computer.

Key Map

• Encoder
  • Single-Tap = Next Layer
  • Double-Tap = Toggle RGB LEDs On/Off
  • Press-Hold = Previous Layer
  • Clockwise Rotation = Next Layer
  • Counter-Clockwise Rotation = Previous Layer
• Button 1:
  • Layer 0 = F13
  • Layer 1 = F17
  • Layer 2 = F21
• Button 2:
  • Layer 0 = F14
  • Layer 1 = F18
  • Layer 2 = F22
• Button 3:
  • Layer 0 = F15
  • Layer 1 = F19
  • Layer 2 = F23
• Button 4:
  • Layer 0 = F16
  • Layer 1 = F20
  • Layer 2 = F24
• RGB LED Colors:
  • Layer 0 = Red
  • Layer 1 = Green
  • Layer 2 = Blue

Raw HID Functionality

• Move to specified layer

How to Install the Firmware?

1. Go through The QMK Tutorial.
2. Insert the desired config.h, rules.mk, and keymap.c files where appropriate prior to building and uploading the firmware.

Notes

• My BigKNOBv2 was custom-ordered through Etsy.
• The keymap was optimized for use with the BigKNOBv2 dented encoder.
• Additional QMK resources are compiled in the QMK Syllabus.
• A VoiceAttack plugin for communicating with BigKNOBv2 is also available.
