# Rotary Numpad
|
|
|
|
|
|
|
|
|
|
This is a personal project of mine where I wanted a number pad that I can put on the left side of keyboard that doesn't have a numberpad. I fell in love with the feel of rotary encoders on my 3d printer, so added three to be able to play around with.

* Keyboard Maintainer: [rabijl](https://github.com/rabijl)
|
|
* Hardware Supported: Sparkfun Pro Micro 5V (atmega32u4)
|
|
* Hardware Availability: https://www.sparkfun.com/products/12640

## How to build from scratch
|
|
|
|
I handsoldered gateron blue switches to a 3D printed case. The design is modified from the [Ultipad](https://www.thingiverse.com/thing:4248565). \
|
|
I used a sparkfun Pro Micro as my microcontroller and the pinout can be found in the `info.json`. I found this [site](https://golem.hu/article/pro-micro-pinout/) \
|
|
to be very useful to identify different pins. You can find useful information on rotary encoders from the qmk docs [here](https://docs.qmk.fm/#/reference_info_json?id=encoders) and [here](https://docs.qmk.fm/#/feature_encoders).
|
|
|
|
### matrix
|
|
|
|
Due to the three rotary encoders, I had to use most of the available pins. Fortunately, all the buttons still fit in a 6x4 matrix. Looking at the diagram below, the three buttons in the first column correspond to each encoder button.

## Flashing
|
|
|
|
Make example for this keyboard (after setting up your build environment):
|
|
|
|
qmk compile -kb handwired/rabijl/rotary_numpad -km default
|
|
|
|
Flashing example for this keyboard:
|
|
|
|
qmk flash -kb handwired/rabijl/rotary_numpad -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).
|
|
|
|
## Bootloader
|
|
|
|
Enter the bootloader in 3 ways:
|
|
|
|
* **Short reset leads**: tap the reset lead to ground twice quickly after qmk is in flash mode
|
|
* **Keycode in layout**: double tap the key mapped to `QK_BOOT`. On the default keymap this can be found by holding in key (0,C) and tapping key (0,A), see the matrix section for the positions of these keys.
|
|
* **Bootmagic reset**: Hold down the key at (0,A) in the matrix (see matrix section) and plug in the keyboard
|
|
|
|
**Note:** if the keyboard doesn't show up after putting the keyboard in reset mode, check that
|
|
your user is added to the `tty` and/or `uucp` groups. \
|
|
You may need to logout after adding these groups to your user, for the changes to take affect.
