# Unsplitted ergo Keyberon [![Build status](https://travis-ci.org/TeXitoi/keyberon-f4.svg?branch=master)](https://travis-ci.org/TeXitoi/keyberon-f4)

## Presentation

A handwired unsplitted ergo keyboard. It uses
[keyberon](https://github.com/TeXitoi/keyberon) for its firmware.

The case is totally parametric: you can customize a lot of things, including:
- number of rows
- number of columns
- number of thumb keys
- angle between the two halves
- column stagger

### First version

### Second version

The dev board has a dedicated cutout.

6×3+4 layout with a bit more stagger.

### Third version

The "plate" is now thick and play the role of case, with just a flat
sheet for the back.

Default version (6×3+4):

![Keyberon v3](images/keyberon-f4-v3.jpg)

Minimal version, for testing, with
```
nb_cols=2;
nb_rows=2;
nb_thumbs=2;
```

### Fourth version

Choc height and spacing (optional), aligned thumb cluster (optional).

Side view, with choc switches on the left, and MX switches on the
right. 5 euro cent coin (21.25 mm of diameter) for scale.

I use this keyboard mostly over the laptop keyboard.

Everything can be found for less than $60 new on Aliexpress without
the case.

## Building

You can follow the [building guide of keyberon
grid](https://github.com/TeXitoi/keyberon-grid/blob/master/BUILDING.md)
or any other handwiring guide. I recommand to read a few to have
different visions.

For the wiring of the dev board, refer to the source code for the pins.

## Compiling

Install the rust toolchain

```shell
curl https://sh.rustup.rs -sSf | sh
rustup target add thumbv7em-none-eabihf
rustup component add llvm-tools-preview
cargo install cargo-binutils
```

Compile the firmware

```shell
cargo objcopy --bin keyberon-f4 --release -- -O binary keyberon.bin
```

## Flashing using DFU

Put the developement board in DFU mode by pushing reset while pushing
boot, and then release boot. Then flash it:
```shell
dfu-util -w -d 0483:df11 -a 0 --dfuse-address 0x08000000:leave -D keyberon.bin
```

The LED on the board should react to caps lock (if you push caps lock
on another keyboard, the light should toggle), and the user button
send space.
