- # ErgoDox EZ
-
- The Ez uses the [Teensy Loader](https://www.pjrc.com/teensy/loader.html).
-
- Linux users need to modify udev rules as described on the [Teensy
- Linux page]. Some distributions provide a binary, maybe called
- `teensy-loader-cli`.
-
- [Teensy Linux page]: https://www.pjrc.com/teensy/loader_linux.html
-
- To flash the firmware:
-
- - Build the firmware with `make <keyboardname>:<keymapname>`, for example `make ergodox_ez: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 corner.
-
- - Click the button in the Teensy app to download the firmware.
-
- See also [video demonstration](https://www.youtube.com/watch?v=9PyiGUO9_KQ) using Teensy in auto mode.
-
- 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_<keymap>.hex´
-
- - Press the Reset button by inserting a paperclip gently into the reset hole
- in the top right corder.
-
- ## Settings
-
- You may want to enable QMK_KEYS_PER_SCAN because the Ergodox has a relatively
- slow scan rate.
