# Atreus

![Atreus](https://atreus.technomancy.us/photos/1.jpg)

A small mechanical keyboard that is based around the shape of the human hand.

Keyboard Maintainer: [Phil Hagelberg](https://github.com/technomancy)  
Hardware Supported: Atreus, PCB-based or hand-wired  
Hardware Availability: https://atreus.technomancy.us

These configuration files are specifically for the Atreus keyboards created by Phil Hagelberg (@technomancy). This keyboard is available in several variants: powered by a Teensy 2 or STM32F103C8T6 based MCU board (usually hand-wired), powered by an A-Star or ProMicro (usually using a PCB). You will need to use different `make` commands depending on the variant you have; see examples below.

Make example for this keyboard (after setting up your build environment):

    make atreus:default:avrdude

If you would like to use one of the alternative controllers:

    make atreus/astar:default:flash
    make atreus/teensy2:default:flash
    make atreus/promicro:default:flash
    make atreus/f103:default:flash

If your keyboard layout is a mirror image of what you expected (i.e. you do not get QWERTY on the left but YTREWQ on the right), then you have an A-Star powered Atreus (older than March 2016) with PCB labels facing *down* instead of up. Specify that by adding `PCBDOWN=yes` to your `make` commands, e.g.

    make PCBDOWN=yes atreus:default:avrdude

*Unlike the TMK firmware, these commands should be run from the root of the repository, not the directory containing this readme.*
