ErgoDox

The ErgoDox is a split ergonomic keyboard originally developed by Dominic "Dox" Beauchamp.

• The ErgoDox EZ is a Teensy-based split mechanical keyboard, sold assembled and with warranty at ErgoDox-EZ.com.
• The ErgoDox Infinity is an ARM-based split mechanical keyboard, sold from time to time in kit form at MassDrop.com

The ErgoDox EZ code is maintained by Erez Zukerman and is officially supported by the EZ -- the keyboard ships running QMK from the factory.

The ErgoDox Infinity code is maintained by Fredizzimo, as a community contribution.

Standard Build Instructions

To build QMK for the ErgoDox, see the official build guide.

Additional resources

A graphical configurator for the ErgoDox EZ is available at configure.ergodox-ez.com. It outputs QMK-compiled binaries, as well as source code for your layout, which you can use as a jumping-off point to further customize in QMK.

Flashing Firmware

ErgoDox EZ

The Ez uses the Teensy Loader.

Linux users need to modify udev rules as described on the Teensy Linux page. Some distributions provide a binary, maybe called teensy-loader-cli.

To flash the firmware:

• Build the firmware with make keymapname, for example make default

• This will result in a hex file called ergodox_ez_keymapname.hex, e.g. ergodox_ez_default.hex

• Start the teensy loader.

• Load the .hex file into it.

• Press the Reset button by inserting a paperclip gently into the reset hole in the top right corder.

• Click the button in the Teensy app to download the firmware.

To flash with ´teensy-loader-cli´:

• Build the firmware with make keymapname, for example make default

• Run ´<path/to/>teensy_loader_cli -mmcu=atmega32u4 -w ergodox_ez_.hex´

• Press the Reset button by inserting a paperclip gently into the reset hole in the top right corder.

ErgoDox Infinity

The Infinity is two completely independent keyboards, and needs to be flashed for the left and right halves seperately. To flash them:

• Build the firmware with make infinity-keymapname

• Plug in the left hand keyboard only.

• Press the program button (back of keyboard, above thumb pad).

• Install the firmware with sudo make infinity-keymapname-dfu-util

• Build right hand firmware with make infinity-keymapname MASTER=right

• Plug in the right hand keyboard only.

• Press the program button (back of keyboard, above thumb pad).

• Install the firmware with sudo make infinity-keymapname-dfu-util MASTER=right

More information on the Infinity firmware is available in the TMK/chibios for Input Club Infinity Ergodox

Infinity Master/Two Halves

The Infinity is two completely independent keyboards, that can connect together. You have a few options in how you flash the firmware:

• Flash the left half, rebuild the firmware with "MASTER=right" and then flash the right half. This allows you to plug in either half directly to the computer and is what the above instructions do.

• Flash the left half, then flash the same firmware on the right. This only works when the left half is plugged directly to the computer and the keymap is mirrored. It saves the small extra step of rebuilding with "MASTER=right".

• The same as the previous one but with "MASTER=right" when you build the firmware, then flash the same firmware to both halves. You just have to directly connect the right half to the computer.

• For minor changes such as changing only the keymap without having updated any part of the firmware code itself, you can program only the MASTER half. It is safest to program both halves though.

ErgoDone

The ErgoDone uses its own HID bootloader and needs to be flashed using the TKG Toolkit.

• Build the firmware with make ergodone-keymapname

• While plugging in the USB cable, hold the two right-most keys on the left half of the ErgoDone to enter FLASH mode.

• Use the utility from TKG Toolkit to flash the keyboard: hid_bootloader_cli -mmcu=atmega32u4 ergodox_ergodone_keymapname.hex
