Dactyl
See https://github.com/adereth/dactyl-keyboard
The Dactyl 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 handwired/dactyl:<keymapname>, for examplemake handwired/dactyl:default - 
This will result in a hex file called
handwired_dactyl_<keymapname>.hex, e.g.handwired_dactyl_default.hex - 
Start the teensy loader.
 - 
Load the .hex file into it.
 - 
Put the Teensy in firmware-loading mode:
- If your current layout has a RESET key, press it.
 - If you lack a RESET key, press the reset button on the Teensy board itself.
 
 - 
Click the button in the Teensy app to download the firmware.
 
To flash with ´teensy-loader-cli´:
- 
Build the firmware as above
 - 
Run
<path/to/>teensy_loader_cli -mmcu=atmega32u4 -w handwired_dactyl_<keymapname>.hex - 
If you like, you can do both at once:
make handwired/dactyl:<keymapname>:teensy - 
Put the Teensy in firmware-loading mode:
- If your current layout has a RESET key, press it.
 - If you lack a RESET key, press the reset button on the Teensy board itself.
