Daniel Burkholder af5f59636e Keyboard: Dactyl - Only initialize relevant variables (#3771)
This small change prevents an unused variable from being initialized, throwing a warning during compilation, thus ending fatally.

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 example make 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.
