13 To flash the firmware:
15 - Build the firmware with `make handwired/dactyl:<keymapname>`, for example `make handwired/dactyl:default`
16 - This will result in a hex file called `handwired_dactyl_<keymapname>.hex`, e.g.
17 `handwired_dactyl_default.hex`
19 - Start the teensy loader.
21 - Load the .hex file into it.
23 - Put the Teensy in firmware-loading mode:
24 * If your current layout has a RESET key, press it.
25 * If you lack a RESET key, press the reset button on the Teensy board itself.
27 - Click the button in the Teensy app to download the firmware.
29 To flash with ´teensy-loader-cli´:
31 - Build the firmware as above
33 - Run `<path/to/>teensy_loader_cli -mmcu=atmega32u4 -w handwired_dactyl_<keymapname>.hex`
35 - If you like, you can do both at once: `make handwired/dactyl:<keymapname>:teensy`
37 - Put the Teensy in firmware-loading mode:
38 * If your current layout has a RESET key, press it.
39 * If you lack a RESET key, press the reset button on the Teensy board itself.
