# Big Knob
|
||||
|
||||
|
||||
|
||||
A 3D printed single encoder volume knob with a SPI Screen.
|
||||
|
||||
* Keyboard Maintainer: [jpe230](https://github.com/jpe230)
|
||||
* Hardware Supported: Big Knob PCB, Sparkfun ProMicro RP2040 (*See notes*)
|
||||
* Hardware Availability: <https://github.com/Jpe230/big_knob>
|
||||
## Features
|
||||
|
||||
The Big Knob was designed to be easy to assemble:
|
||||
* Designed to be used with a RP2040 board (*See notes*)
|
||||
* ST7735 0.96 inch color display
|
||||
* RGBLight
|
||||
* Easy to 3D print
|
||||
|
||||
### Notes
|
||||
You can use any compatible RP2040 board (I.E.: KB2040, Elite Pi, etc), but you will need to modify the pin definition to match you board
|
||||
|
||||
## Flashing
|
||||
|
||||
Make example for this keyboard (after setting up your build environment):
|
||||
|
||||
qmk compile -kb jpe230/big_knob -km default
|
||||
|
||||
Flashing example for this keyboard:
|
||||
|
||||
qmk flash -kb jpe230/big_knob -km 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).
|
||||
|
||||
## Building Instructions
|
||||
|
||||
You can find the required materials and the instructions to build your own Big Knob in the [project repo](https://github.com/Jpe230/big_knob)
|
||||
|
||||
## Bootloader
|
||||
|
||||
Enter the bootloader in 3 ways:
|
||||
|
||||
* **Bootmagic reset**: Hold down the encoder buitton and plug in the keyboard
|
||||
* **Physical reset button**: Briefly press the reset button on the front of the RP2040 board
|
||||
* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
