This is a fork of Ben Blazak's ErgoDox firmware.
The official website for the ErgoDox is ErgoDox.org. See also the geekhack and deskthority discussion threads. Kits are periodically for sale on Massdrop, who also hosts build instructions and a `web UI`_ for configuring layouts.
(These instructions are only for the CLI Teensy loader from PJRC.)
Assuming you have teensy_loader_cli somewhere on your $PATH, simply run the following commands from the src directory after running make.
teensy_loader_cli -v -mmcu=atmega32u4 -w ../ergodox-firmware/src/firmware.eep teensy_loader_cli -v -mmcu=atmega32u4 -w ../ergodox-firmware/src/firmware.hex
