A 65% keyboard by Ducky.
This firmware was tested on the Ducky One 2 SF 1967ST version.
make ducky/one2sf/1967st:default
To enter the 1967ST bootloader to flash, boot the keyboard while holding D+L.
There are then two ways to flash the keyboard:
pip install --user nuvoton-isp
nuvoisp -f ducky_one2sf_ansi.bin
Alternatively you can use elfmimi's nu-isp-cli which is more complete than nuvoisp and allows flashing .hex files as well.
cargo install nu-isp-cli
nu-isp-cli flash ducky_one2sf_ansi.bin
