Quick Guide: How to edit keymap on Atreus62



Did you get a pre-built Atreus62 from Profetkeyboards.com with no clue how to edit and re-flash your layout? Here are the steps I took to get it working on a Mac. YMMV:

  1. Download the QMK firmware from the Git repo (click the green ‘clone or download’ button and download the zip. unzip on your computer)
  2. Navigate to the keyboards/atreus62 folder, duplicate the ‘default’ folder, and rename it to something like ‘mylayout’
  3. Open up mylayout/keymap.c in a text editor and start editing the layers to your heart’s content. The keycodes can be found in the readme.
  4. Open up your terminal and navigate to the root folder of the qmk repo you just downloaded, i.e. ‘qmk_firmware-master’ and run ‘make atreus62’. This will spit out 3 hex files to the root folder, one of which should be ‘atreus62_mylayout.hex’
  5. Go to the Quick Start guide and install avrdude
  6. Determine the path to the keyboard by running some terminal commands. Note: when it says to put your keyboard in bootloader mode, all you have to do is get a paperclip and stick it in the hole in the back of the atreus62. You now have 8 seconds of bootloader mode.
  7. Flash your hex to the keyboard by putting it in bootloader mode and running the terminal command as shown a little farther down here. For example, in my case,
    avrdude -p atmega32u4 -c avr109 -U flash:w:atreus62_mylayout.hex -P /dev/cu.usbmodem1411


That’s it! From here on, I can tweak the layout, compile the hex, and flash it.

Here’s my current layout:
